Transplanting marijuana plants
Transplanting marijuana plants can be one of the trickiest parts of growing cannabis. It may seem overwhelming, but when properly researched it can be done with ease by just about anyone.
About transplanting marijuana plants
Once your plants have established a stable root system, they are ready for a period of major foliage growth.
So what makes transplanting cannabis so important? What would even happen if you didn’t do it? In this article, we will answer those questions, and will dive into the following topics:
If you don’t transplant your plants in time they might get rootbound. Rootbound means that the roots have grown all the way around the edges and bottom of the container because it is nog big enough. Your plant will not grow anymore until you transplant it to a larger container.
The following symptoms are signs that your plant is rootbound:
- Stunted Growth
- Smaller and slower bud production
- Easy to burn with low % nutrient solution mixtures
- Red stems

The right time to transplant your cannabis plants is when they have an established, sturdy root system in place. This is the case when the roots grow out of the bottom of the pot. The plant is ready to focus its energy on vegetative growth now, so it needs to be moved to a larger container.
Note: Marijuana plants need around 2 gallons of soil for each foot of growth.
You will need to educate yourself about how to do this properly, since making even a small mistake during the process could have a devastating effect. You will also have to carefully choose where you are going to put your cannabis plants permanently to live out their adult lives.
Transplanting cannabis plants at this stage is always necessary, regardless of how you sprouted your plants to begin with. They simply cannot thrive if they are grown in containers for their whole lives, so you cannot avoid the transplantation process. The best way to deal with this is through research and planning.
So what could happen if you make a mistake while transplanting your cannabis plants? Your plants could go into shock, which might cause their leaves to turn yellow and then wither, finally dying and dropping off the plant altogether. In some more serious cases, the plant itself could actually die from the trauma.
While risky, transplanting your plants will have an overwhelmingly positive effect (when done responsibly). It will help speed up the maturing process of the plant while simultaneously requiring even less hands-on care from you as the grower. In summary, it’s well worth the risk and hassle in the end.

Indoor or outdoor transplanting?
Before beginning the transplanting process, you will first need to make some decisions about your permanent grow site. The location is everything, as it will determine your cannabis plants’ growing environment (and, therefore, their rate of success) as well as your own security.
If you want more control over the environment in which your plants are growing, you may be interested in setting up a permanent grow site indoors. With this method, you can grow all your plants in larger separate containers of some sort (check these containers).

This can be a great way to ensure the health of your plants since you would control every aspect of their lives. On the other hand, growing your cannabis plants indoors will also require you to use a lot more money, time, and effort. Whether it is light, food, water, temperature or ventilation, you will have to provide it yourself.
For growers on a budget or who prefer a more natural method of growing, setting up a grow site outdoors might make the most sense. It costs much less in both money and effort.
That being said, with this method it is even more important to choose the right grow site for your plants, since it will have a significant effect on both the environment around your plants, as well as your own personal security. It will need to be a safe place with easy access, where you can ensure safety for both yourself and your cannabis plants.
When to transplant
The basic idea behind transplanting at a certain time is to do it when your plants’ roots have reached as far as they can grow within the constraints of their container. Roots actually tend to grow further and faster when they are enclosed in a container; it’s almost as if they are eager to reach open space as soon as possible.
Strangely enough, roots that are already planted straight into the ground do not grow with the same amount of urgency. So what happens if you leave your plants in a container for too long? The answer is simple: they’ll just stop growing altogether.
Containers are not the only thing guilty of causing such a response in the plant. Peat plugs can do the same thing since their mesh perimeter usually acts as a hindrance to the roots, and they stop growing as if they were contained in a plastic pot. This will cause them to stop growing as well.
Once your cannabis plants have sprouted, two leaves that are oblong in shape will start to be visible. These are called cotyledons and they come out from the one tiny stem that will pop up from the soil. They don’t resemble the easily recognized marijuana leaves, but after just a few days they will drop off and normal marijuana leaves will emerge. This shows you that your plants are beginning their seedling phase of life.
Plants in this phase are still relatively small in size, but their roots will begin to grow and develop into a proper root system. This system, though nicely developed, is still quite fragile.
You cannot yet move your plants while they are in their seedling phase, but do ensure that they have plenty of light and water (or just moisture in the soil). The seedling phase can be between two and six weeks long.
So how can you identify the time when your plants are ready for transplantation?
Doing it too early would be devastating for your tender seedlings, so you must act with caution. Once you suddenly are seeing faster growth of leaves as well as a firmer stem. You can test the firmness of the stem by grabbing it with your hand (gently) without doing any damage to it. If these things are happening to your young plants, they have officially entered the vegetative growth stage of their life.
You can, of course, begin the growing season a bit earlier by using peat plugs. This is ideal for growers who are located in climates where the growing season is naturally shorter.
If you do go with peat plugs, make sure you are always aware of the mesh perimeters and whether root tendrils are emerging from underneath them. As soon as you see this you will need to transplant the seedlings into a bigger container or else into the ground outdoors. If you don’t, the growth of your plant could remain stunted forever.

How to transplant
The first thing you need to do when transplanting your plants to a new, permanent location is to choose a spot for them. There are three types of locations that you can choose between.
The first one is an indoor location that can be accessed with ease but is not easily noticed by other people. A second option would be to move your plants outdoors, where many of the valuable resources they need come at no cost to you. The third option is a sort of indoor-outdoor hybrid: you can move your plants to larger containers, but in turn, move these containers outdoors temporarily.
During the first 3 weeks of flowering root-binding can seriously decrease your yield. The buds and leaves wont continue to grow because the plant cant grow new roots to support them.
If you are most concerned about the discovery of your plants, the third option might be for you because it means that you will be able to quickly relocate your crop in case of detection. It also works well for moving your plants away from pests.
Out of the three options, moving your plants from one container to another is most likely the simplest and most straightforward option available to you.
No matter what option you choose to go with, there are a few key factors to your successful transplantation. First and most obviously, you need to make sure that new soil (whether in the ground or in containers) is fully prepared before you begin the transplantation process.
If you are moving the plants into new pots, make sure that each pot is 4 gallons at the very smallest if it’s their permanent container. If you are going to move your plants to an outdoor location, simply dig a hole that is a few inches greater in size than the pots that your plants have been living in thus far. Make sure to have piles of dug up soil around the hole as well, so that you can push it back in once you have completed the move.
You should actually keep the plants in the soil that they have already been growing since it will reduce the amount of shock that it undergoes, and will instead ease your plant into its new environment. If you have grown your plants within a closet until now, they are especially susceptible to shock, so be particularly cautious.
The next factor that you need to pay attention to is the condition of the soil that your plants are currently living in. It needs to be moist but not wet, and not dry enough to crumble. The most important thing is that your soil sticks together during the transplantation, keeping the shape of its original container (wiki on transplanting).
The process is simple. Put the palm of your hand on the soil in its original pot, keeping the plant’s stem between two of your middle fingers. Your other hand should be beneath the plant. Using both hands, smoothly flip the pot upside-down, putting the full contents and weight of the plant and its soil into your hand that’s holding the stalk of the plant.
Then put away the container, as you will no longer be needing it, and put your hand back on the bottom of the contents, where you should be able to see the white tendrils of the roots. You then put the whole thing into one of the holes you have already dug in the ground.
Do not panic if large pieces of soil fall from the roots of the plant. Your only priority is getting the plant’s roots back underground and covered completely with soil. With a peat plug, the mesh surrounding your plant’s roots should be pulled off and discarded since your plant will no longer be engulfed by water.
Once you have pushed all the soil onto plant’s roots, make sure to give those roots plenty of water. Use up a full gallon that has added plant food.
The last step is simply to cover up the soil that has been exposed to natural debris and leaves that are already at this location. This will both slow down the evaporation of the water you just poured, as well as camouflage your garden from unexpected discovery.
Once the plant is fully grown you will need to start thinking about flowering and harvest time. Our free little Harvest Guide will help you determine the best moment to cut your plants.
How and when to transplant cannabis plants
Transplanting is the process of “re-homing” a cannabis plant, or moving a plant into a bigger pot with more soil as it grows bigger.
Growers typically start off the cannabis growing process by planting many seeds in small pots because they don’t know if all of them will sprout—or germinate—and they don’t know if all of them will be female.
Only female cannabis plants produce buds, so if you start growing from regular seeds, you will have to sex them out and discard the males.
Why is transplanting marijuana plants important?
Transplanting gives a marijuana plant’s root system more space to spread out, allowing the plant to grow healthy and strong and to flourish.
When roots become cramped and can’t spread out they can get tangled and become “rootbound”—this will effective choke the plant, leading to a stunted, sickly plant, and can even kill it. A healthy root system will lead to a healthy weed plant.
A plant’s container will determine how much the roots can stretch out, and therefore how big your plant will get. A container that’s too small will stunt it.
You don’t want to plant a seed in a giant pot because you could potentially waste soil if the seed doesn’t make it. Also, if growing weed outdoors, it’s hard to plan out a garden and where to put your seeds in the ground if some seeds don’t make it.
Most weed growers start seeds in small 4-inch or 1-gallon pots when germinating.
For the seeds that do make it, they will need bigger homes after several weeks of growing and will need to be transplanted either into a bigger pot or directly into the ground.
When planting into the ground, make sure not to crowd your plants so their roots don’t run into each other.
The symptoms of a rootbound plant include:
- Flimsy new growth
- Stunted flower production
- Stem discoloration (reddening)
- Nutrient sensitivity
A rootbound plant may also appear under-watered. If a plant requires watering more than once a day, it may need to get transplanted.
When to transplant marijuana

Most marijuana plants go through 1-2 transplants during their life but could have more. As an example, transplanting can happen from:
- First container (1-gallon) to second container (2-gallon): 4-8 weeks after seed germination
- Second container (2-gallon) to third container (5-gallon): transplant 8-12 weeks later, or 2 weeks before flowering
Some growers may only transplant once: using the example above, from a 1-gallon to a 5-gallon container, skipping the 2-gallon. And depending on how big you want your weed plants to get, you may transplant into bigger pots than what’s listed above.
The same goes for transplanting outside, in the ground—you can go straight from the first pot into the ground, but it depends on when you transplant and your local climate and weather.
Here are some indicators that your cannabis is ready for a new container.
Number of leaves
Young plants sowed in small containers are usually ready to be transplanted after they’ve sprouted 4-5 sets of leaves, but keep in mind this may vary from strain to strain.
Check the drainage holes at the bottom of the container—a plant should have a healthy and visibly white root system. If roots are growing out of the holes, it’s time to transplant.
Any discoloration or darkening may indicate the plant has become rootbound and a transplant should take place immediately.
End of vegetative stage
A weed plant should be in its final pot or in the ground with plenty of room for its roots before it enters the flowering stage. During flowering, a plant will increase in both size and volume, as the plant itself continues to grow and as buds develop. It will require a substantial amount of space for root development.
How much space does a marijuana plant need?
|Plant height (inches)||Pot size|
|0-6″||4-inch (16 oz.)|
When transplanting cannabis, give the plant at least double the space of its previous container. This reduces the number of times you need to transplant and minimizes the risk of transplant shock, which may occur when a plant experiences extreme stress from root disturbance.
For example, you could go from a 1-gallon to a 2-gallon to a 5-gallon, or from a 2-gallon to a 5-gallon to a 10-gallon.
Medium-sized indoor cannabis plants tend to be fine in 5-gallon containers as a finishing pot. Large outdoor plants may require much bigger containers to reach their behemoth potential, sometimes up to 10- or 20-gallon pots.
When in doubt, always opt for slightly more space than needed. A plant tends to require 2 gallons of soil for every 12 inches of growth it achieves during the vegetative stage. Knowing the potential height of the strain you’re growing is helpful.
Why not start in the largest pot for your marijuana plant?
Growers typically transplant weed plants 1-3 times, moving plants to bigger pots gradually as they get bigger.
If a plant is put in too big of a pot, the roots won’t stretch out that much and won’t soak up as much water. This can cause water to sit in the pot for a long time, waterlogging the plant and leading to root rot.
You can transplant into the largest pot for your weed plant to avoid multiple transplants, but be careful not to water all of the soil—only water around the stalk of the plant where the young roots are.

The process of transplanting weed does not come without risk. Transplant shock can be incredibly detrimental to the growth and development of a cannabis plant, and can even kill it. However, through proper execution, the process of transplanting will benefit the plant and lead to stronger root development and healthier flower production.
First transplant of a cannabis plant
Young cannabis plants should start in a 4-inch or 1-gallon pot. This starting pot should be adequate for a few weeks before transplanting is needed.
Again, the first transplanting should occur after the seedling has sprouted its 4th or 5th set of leaves. To transplant:
- Wash your hands and/or wear gloves to prevent contamination of the delicate roots, and keep the surroundings as sanitary as possible.
- Give the plant a light sprinkling of water to help minimize shock; don’t drench it, as the soil will be difficult to work with.
- Fill the receiving pot with soil, allowing enough space for the new plant.
- Avoid overpacking the soil during and after transplanting—this can compromise drainage and damage the root system.
- Do not disturb or damage the roots when transplanting; the first transplanting poses the greatest risk for shock, which can occur from root damage and agitation.
- Avoid intense light when transplanting; this will help prevent transplant shock as well.
- Fully water in the plant once it’s in its new home.
Additional transplanting of cannabis plants
You may need to transplant your weed plant a second or third time to maximize its growing potential. Always monitor plants for symptoms of distress or overcrowded roots.
To do so, follow the steps above, and make sure the new container is at least twice as big as the old one, if not bigger.
The finishing container is the final home of a plant until it’s harvested. This will be the largest container for a plant, and you always want to transplant into this pot 1-2 weeks before the flowering stage—you don’t want to disturb a plant while it’s flowering.
Keep in mind that large plants may require stakes or other support to avoid structural damage after transplanting.
Transplanting Cannabis: Complete Guide with Kyle Kushman Tips
If you don’t transplant cannabis when it needs to be moved, you could end up with rootbound plants and stunted growth.
Pot size is important when it comes to yield, you want your plants to finish in nice, big pots, but it’s not always sensible to start them this way.
Transplanting cannabis successfully is all about observation, practice and timing.
You need to recognise when your plants are ready to be transplanted, and you need to know how to transplant without stressing or killing them.
For most photoperiod grows, plan to transplant cannabis up to and around three times.
We’re going to look at the full cycle of the plant, when to transplant weed seedlings and transplanting cannabis plants pre-flip, so they can enjoy flowering in their final home.
Why is transplanting cannabis important?
As plants grow above the soil line, the root ball expands below it.
It’s important the plant has enough room to grow in both these dimensions.
Important both for the quality AND the quantity of your final yield.
While it’s true that pot size determines how big your plants can grow, transplanting marijuana directly from a tiny container to a large one can be detrimental.
We’ll talk about this more later on.
The main advantage of transplanting cannabis is that it helps you perfect the watering cycle, allowing the rootball to expand at a manageable rate.
If you don’t transplant your cannabis when it needs to be moved, the roots might outgrow the pot – the plant can become root bound. Root bound cannabis plants struggle to absorb nutrients, oxygen, and water, often leading to sickness and death. Transplanting marijuana plants too soon will have the negative effect of your root ball falling apart.
Growing cannabis is all about providing the most comfort for your plants, allowing them to thrive. One of the best ways to do this is to learn how to transplant cannabis with confidence.
How often do you need to transplant marijuana plants?
If you’ve germinated your cannabis seeds outside of the soil, your first experience of transplanting cannabis plants will be planting them.
Okay, so it’s not a major transplant, but you’re still ‘transplanting’ from the paper towel to the small pot or solo cup.
The first big transplanting decision is when to transplant cannabis seedlings to their first decent-sized plant pot. This will either be an intermediate pot, or their final pot.
Remember: transplanting pot is not something you can predetermine. You need to observe your plants, let them tell you when they’re ready to be moved.
Beginners should think about transplanting weed plants into an intermediate pot. This will help master the wet to dry watering cycle – the best way to water your plants!
Transplanting cannabis seedlings straight into a final container is best left to experienced growers (or those growing autoflowers). Unless your final pot is three gallons or less.
When to transplant your marijuana plant?
You should only really transplant weed plants when:
- Plantinggerminated seeds into their first pot.
- Transplantingpot seedlings into intermediate containers.
- Transplanting into a final grow pot ready for flowering.
The key determining factor in transplanting cannabis is the size of the plant, and, by proxy, the root ball.
You can transplant cannabis as much as needed during the seedling and vegetative stages, but each time you transplant weed, you risk cannabis transplant shock. This is why you need to know exactly how to transplant!
We’ll go into this later on, but for a quick guide and vital tips, you can check out our transplanting video guide right now:
What are the symptoms of a rootbound weed plant?
Thankfully, a rootbound plant is relatively easy to diagnose. Symptoms include:
- Weak new growth.
- Stunted flowering.
- Reddening of the stem.
- Nutrient sensitivity or deficiency.
- Wilting and drooping leaves.
- Soil drying out fast.
- Spots or unusual discoloration on the leaves.
Another telltale sign for transplanting your marijuana plant is when water takes a long time to be absorbed.
You should regularly lift your plant from its pot to check the roots. Are you seeing tangled roots clawing to escape from the pot? This means the soil has become packed and/or rootbound. Either way, it’s time to transplant.
When do you transplant cannabis seedlings?
Spotting when to transplant marijuana seedlings is a skill every grower must learn.
You should first transplant when the young plant sprouts its 4th or 5th set of leaves, and regularly check the drainage holes to assess the condition of the roots.
If the roots are healthy-looking and white, then transplanting your pot doesn’t need to happen immediately. If they’re discolored, growing free of the container, or look tangled, it’s time to get cracking!
Regular checks should help you to transplant before the plant shows huge signs of distress.
Be observant, always.
When do you transplant during the vegetative stage?
Never transplant weed once it begins flowering. Move your plant into its final and largest pot during the onset of the full vegetative phase. Plants transfer much of their energy to bud growth, leaving far less energy for root development than during the vegetive stage.
While flowering, your marijuana shoots for the sky and needs plenty of room to support vital functions. It also needs to absorb all the sweet, sweet, nutes to pump into your buds.
If you’re late to re-pot your weed, don’t do it while it’s flowering. This advice comes from long experience: moving your marijuana at this point spells disaster for your harvest.
Ride it out for now and use the experience to make you a better grower in the future.
How do you choose pot size when transplanting cannabis?
When transplanting cannabis, always pot-up into containers 2-3x the size of the previous one. This reduces the number of times you need to move your plants and minimizes the potential for cannabis transplant shock.
A cannabis plant requires a minimum of two gallons of soil per 12 inches of growth. Knowing the potential height of the strain you’re growing is always handy for planning when to transplant cannabis.
We’re looking at you, sativa lovers!
If you’re unsure of what to expect from your experimental seeds, always opt for more room over less. That way, you won’t be caught off-guard when a twelve-footer dominates your grow room!
Most indoor strains are happy finishing in a five-gallon container. Outdoor strains often dwarf those grown indoors, needing up to 20 gallons of soil per plant.
While planning your weed transplants, use my handy measurement guide on plant height vs. pot size:
- 0–6″ = 16 oz
- 6–12″ = 1-gallon
- 12–24″ = 3-gallon
- 24–42″ = 5-gallon
- 42–60″ = 10-gallon
- 60–84″ = 20-gallon
What do you need to prepare before transplanting pot plants?
Beyond selecting appropriately-sized pots for transplanting marijuana plants, you should prepare a few other things to make the transfer successful.
Prepare young plants by cutting the nutrients in half and letting them dry out as much as possible (not totally).
When you’re transplanting cannabis, removing a plant with a saturated rootstock can severely damage it.
You need to prepare the new medium ahead of the transplant. Flushing or sterilizing helps prevent threats like pests and nutrient imbalances, and you can add food back into the soil with fertilizers and nutrient boosters.
Recycling old earth helps maintain the pH and nutrient levels that your plant already likes, and helps prevent cannabis transplant shock.
Adjust the pH of the new soil to around 6 – 6.5 and always have water ready before you transplant weed plants.
Why not plant seedlings straight into their final home?
Transplanting marijuana seedlings as they grow may sound like hard work, and many new growers skip the transplanting and go straight for large containers.
This can be a mistake.
It’s better to transplant weed than to water small plants in big containers.
When transplanting marijuana seedlings into their final home, you run the risk of waterlogging. A large pot means a lot of soil. Lots of soil needs lots of water, often far more than the plant’s immature root system can handle.
As the roots spread out and colonize the pot, they can become trapped in saturated soil and begin to rot.
Another major reason for not transplanting cannabis into large pots too early is that plants use their stored energy to grow roots. They tend to seek the outside edges of your pot, using a whole lot of this energy to reach the farthest corners.
Transplanting pot plants too soon can, in these cases, actually slow down growth.
All this energy invested in the roots comes at the expense of above-ground growth, like developing leaves.
When you transplant cannabis according to its size and stage, roots can colonize pots quickly, absorbing all the water and nutrients it needs for balanced growth.
In other words—if the pot fits, your buds will blitz!
If transplanting cannabis straight into its final home is your only option, or if you’re ready for the challenge, follow the pro tips below for happier, healthier plants.
- Only saturate the center first, around 50% of the potting media.
- Water your plant in a column pattern—straight down, all the way around, using your seedling as a central point. This encourages roots to take the fastest path to the bottom and promotes upward growth.
- Never let your marijuana dry out during the early stage. Wait until you can see the roots at the bottom of the container to start a wet-dry cycle.
How to transplant cannabis plants
We’ve covered when to transplant cannabis plants, now it’s time to learn how to transplant your marijuana plants.
Freshly germinated seeds are usually happy in their nursery pot for a few weeks. Once they’ve developed four to five sets of leaves, it’s time to move the plants into a fresh new home.
Transplanting seedlings: step by step
Follow these steps to transplant weed safely, minimize the risk of cannabis transplant shock, and maximize your plant’s happiness.
Sterilize the area as much as possible and wash your hands (or wear clean gloves). These actions prevent contamination affecting the roots.
Make sure the soil is relatively dry – wet soil will fall apart when you pull it out.
Prepare your receiving pot with new soil that’s been flushed, sterilized, tested, and fertilized.
Remove the plant from its current pot by squeezing the container and flipping it upside down.
Put it straight into the new pot with the old soil to minimize the risk of shock. Leaving your weed outside of soil for too long, or exposing the roots to bright light can cause severe cannabis transplant shock.
Now your plants are settled, give them a good watering.
Vegetative transplanting: step by step
Depending on the growth rate, and if you stick to the double-up rule (by making each new pot double the size of the previous one,) your next crucial time for transplanting cannabis plants is when they start vegging.
Having your plant in its largest container at least two weeks before flowering begins is a key to bountiful yields.
Transplanting pot plants at this stage is a little riskier – cannabis transplant shock this far into the lifecycle could spell disaster for your harvest.
Let’s look at how to get it right, every time!
Prepare a clean area for the transplant.
Amend your potting medium and add it to the new pots, leaving plenty of room for the root ball. The soil shouldn’t fully fill the pot, it needs to be a few inches off the rim.
Transplanting cannabis plants into soil with the same nutrients, electrical conductivity (EC), and pH for cannabis levels as the old soil significantly reduces the threat of shock.
Flush the new soil, take measurements, and saturate it with the same nutrient mix you fed your plant before.
The soil should be fluffy and light, so you can easily make a hole big enough to sit the rootball.
Spray a little water over the plant and gently squeeze the container to loosen the soil.
Position yourself over the new pot or your compost pile. Hold the base with one hand as you turn the plant upside down. With your other hand, slide the container off.
Seat the root ball in the hole and cover with loose soil, creating an even soil level.
Keep things like light, heat, and humidity consistent until it’s settled into its new soil.
How to avoid cannabis transplant shock
Many beginners are unnecessarily fearful of moving their plants in case cannabis transplant shock occurs.
Every time you move your plant, it’s at risk of shock.
We hear you—nobody wants stunted growth and lower yields.
But here’s the good news—Mother Nature is very forgiving, and with a little due diligence, she’ll take care of you just like she takes care of the earth.
With a little knowledge, even first-time cultivators can avoid shock when transplanting cannabis.
Most shock occurs when you move a plant out of the ground to somewhere entirely new. New soil, new pH levels, new humidity levels. All these features make your plant nervous, so keep your conditions as consistent as possible.
Transplanting weed plants is a unique method of potting up.
You can control every element as you simply move your plant to a bigger space with the same potting media.
To ensure your weed doesn’t fall victim to cannabis transplant shock, follow these basic precautions:
- Take extra care when transplanting marijuana seedlings. Don’t touch their fragile roots as you move them.
- Prune dead or decaying older plant roots to encourage fibrous structures—but don’t break them apart.
- Use the same potting media and fertilizers.
- Flush your soil and test its EC and pH before transplanting weed plants.
- Fertigate the new earth with the same nutrient solution.
- Execute the transplant fast and efficiently. Minimize air and light exposure.
- Return your plants to where they’re happy. Don’t change the light, heat, or humidity until your plants start growing again.
Follow these rules, and instead of shock, your plant will thank you for your efforts with a growth spurt.
How’s that for a pleasant reward?
Is there anything you should do or avoid after transplanting?
After transplanting cannabis seedlings or vegetative weed, there are a few other things you can do to ensure the move doesn’t hurt.
Lay off any training that might put your marijuana under more stress.
After transplanting cannabis plants, you should wait a few days before resuming training and topping.
ALWAYS try to wait till the plant shows signs of healthy new growth. This is nature’s way of telling you “I’m ready. Let’s do this!”
Large plants may need some support in their new home. Consider a frame, plant stake, or other support structure to stop the larger ones toppling over.
When transplanting marijuana plants into their new home before flowering, don’t flip them straight after.
Give them time to get into the new groove to ensure they’re in the right frame of mind to enter the next phase. Let them settle, spread, and secure themselves in the new soil for up to two weeks before flipping.
How do you feed your cannabis plant after transplanting?
Flushing and sterilizing your new soil before transplanting cannabis is key to preventing myriad health risks.
But wait—won’t this leave your plant hungry when it arrives in its new home?
Totally! That’s why fertigating your potting media is essential!
Using the same solution you feed your plants before transplanting marijuana ensures it’s got everything it needs from the get-go.
Remember to recycle the old soil and test the new mix’s pH and EC levels before transplanting cannabis, just to be on the safe side. Your plant shouldn’t need additional nutes beyond its usual cannabis feeding schedule for a few weeks.
Now you’ve moved your ladies, be extra vigilant with them for the next few days. Monitor your plants for any signs of deficiency. Yellow leaves and purple stems are signs that something isn’t right with your pH levels after transplanting your marijuana plant.
Consider upping the nutes a few weeks later. Push them as far as possible for optimal crop outcomes, but be on the lookout for nitrogen-burnt tips.
These indicate that you’ve pushed your plant as far as it’ll go.
What about autoflowering plants: can you transplant them?
Autoflowering strains are one of the easiest to grow and boast rapid growth rates. They can mature within ten weeks after germination.
Transplanting cannabis of this type is generally a bad idea, though auto-experts like Kronic would disagree. Check out Kronic’s video on re-vegging autos – his argument for transplanting autoflowers is compelling!
For most growers, there isn’t enough time in an autoflower’s life cycle to overcome the stress of transplant.
If you must transplant your autos, timing is crucial. Only do it once—when your plant has grown four or five sets of leaves and has a robust root system.
