Why Repot Your Plant?
You should repot your cannabis plant when it becomes rootbound. This means that the roots have filled up the pot and are growing in a circular pattern around the edge of the pot. When this happens, the plant can’t take in enough nutrients and water, which can stunt its growth.
The plant is rootbound
If you notice your plant’s leaves drooping, even when you’ve watered it recently, it could be a sign that the roots are constricted and need more space. When cannabis plants are rootbound, they’re unable to absorb as much water and nutrients, which can lead to stunted growth.
Other signs that your plant is rootbound include:
-Excessively long roots growing out of the drainage holes in the bottom of the pot
-Roots circling the inside of the pot
-Soil that is dry on top but wet and mushy below
If you think your plant might be rootbound, gently remove it from its pot and check the roots. If they’re white and healthy, the plant probably just needs to be fertilized. If they’re dark and mushy, it’s time to repot.
You’re changing mediums
If you’re changing the type of growing medium you’re using, such as switching from soil to hydroponics, or from one hydroponic system to another, it’s best to repot your plant. Any time you make a change to your plant’s environment, there’s risk of stressing your plant. Repotting will help reduce that stress.
You want to refresh the potting mix
Over time, the potting mix will break down and become less effective at draining and aerating the roots. This process is accelerated in hot weather and when the plant is heavily watered. If the potting mix feels spongy or if water isn’t draining away quickly, it’s time to repot.
You can also refresh the potting mix by top-dressing with fresh mix. This is especially helpful if the top layer of mix is starting to look dusty or if you just want to give your plant a boost. Be sure to use a sterile potting mix and avoid getting any fresh mix on the stem or leaves of the plant.
When to Repot Your Plant
The time to repot your cannabis plant is when the roots have outgrown the current pot. The plant will need a new pot that is about 2 inches larger in diameter than the current pot. If you wait too long to repot the plant, the roots will start to grow out of the drain holes in the bottom of the pot.
The plant is rootbound
One of the most common signs that a plant needs to be repotted is when it becomes rootbound. Rootbound means that the roots of the plant have become so dense that they’re growing in a circular pattern around the bottom of the pot, rather than growing straight down.
Other signs that a plant is rootbound include:
-The plant is growing slowly
-The plant has stopped blooming
-The roots are coming out of the bottom of the pot
-The plant is wilting, even when it’s been watered properly
If you see any of these signs, it’s time to repot your plant.
You’re changing mediums
The vast majority of the time, you’ll be repotting because you’re changing mediums. For instance, you’ve started your plants off in Rockwool cubes or coco coir and want to transplant them into a soil mix.
In this case, you’ll want to transplant your plants while they’re in the vegetative stage. This will give them time to adjust to their new environment and to grow bigger before they start flowering.

##Expansion:
Another common reason to repot is because your plant is healthy and requires a larger pot. In general, you’ll want to repot every 2-3 months while your plant is in the vegetative stage. Once your plant starts flowering, you can slow down on therepotting.
You’ll know it’s time to repot when you see your plant’s roots growing out of the drainage holes of its current pot. When this happens, it’s difficult for your plant to take up water and nutrients, which can cause problems down the road.
You want to refresh the potting mix
Cannabis plants are fast growers, often putting on several inches of growth a week. Once they’ve outgrown their initial pot, it’s time to move them into a larger one. But how do you know when it’s time to repot your plant?
Here are a few signs to look for:
-The roots are coming out of the drainage holes in the bottom of the pot.
-The plant is growing faster than usual and you’re having to water it more frequently.
-The potting mix is breaking down and no longer retains moisture well.
-The plant is toppling over because the roots can’t support the weight of the foliage.
If you see any of these signs, it’s time to repot your cannabis plant.
How to Repot Your Plant
The size of your pot will ultimately determine how often you need to repot your cannabis plant. If you’re growing in a small pot, you’ll need to repot more often than if you’re growing in a large pot. The frequency with which you repot will also depend on how fast your plant is growing. A plant that is growing quickly will need to be repotted more often than a plant that is growing slowly.
The plant is rootbound
When you see that your plant’s roots have started to circle the inside of the container, it’s a sure sign that it’s time to repot. You’ll also notice that the plant is becoming stunted in growth, with yellowing leaves and fewer flowers or buds. All these problems can be remedied by transplanting your rootbound cannabis plant into a larger pot.
You’re changing mediums
If you’re growing in soil and want to change to coco, or vice versa, you’ll need to repot your plant. You may also need to repot if you’re switching from one brand of coco coir to another, as they can differ in pH and other factors. Generally, it’s a good idea to flush your media with plain water a week or so before repotting to help reduce the amount of nutrients your plant will be taking up.
You want to refresh the potting mix
The main reason to repot a cannabis plant is to refresh the potting mix. Over time, the mix breaks down and doesn’t hold nutrients as well as it did when it was new. The breakdown of the mix also leads to compaction, so the roots have a harder time getting access to oxygen, water, and nutrients.
