Depending on the size of the pots you’re using, you have to transplant your plants after a number of weeks.
They can now go to the pot you’ll also let them flower in.
It’s key to not damage the roots during the transplanting process, since these easily break off.
There are certain techniques and signals to safely transplant your plants.
In this chapter I’ll teach you everything about repotting plants.
How to transplant
Step by Step
How to transplant marijuana
- Wait until roots grow out the bottom of the pot
- Make sure your soil is moist
- Squeeze the pot a couple of times, so the soil doesn’t stick to the edge
- Grab the pot from above, with the plant between your fingers
- Turn the pot and carefully remove this from the roots
- Put the plant in the new pot, add soil and water it
Once the roots grow out of the bottom of the pot, it’s time to transplant the plant.
If you transplant too early, your root system might still be very small and you could easily damage or break it by the weight of the soil when transplanting.
If you transplant the plant too late, the roots can no longer grow and the plant will stop growing.
This is called rootbound.
Try to avoid rootbound at all times, because the plant won’t grow if the roots can’t develop.
This isn’t much of a problem during the growing stage, because you can still catch up, but you don’t want your plants to stop during the flowering phase, because you won’t be able to catch up, so you’ll end up with a lower yield…
During transplanting, the soil has to be a bit moist, so the clod will easily come out of the pot.
A very dry soil won’t come off the pot and can harm the roots. It’s also not good for a plant to be so dry.
If the soil is soaking wet, it could fall apart when putting the plant in the pot, causing the root system to break off.
This is a nice trick to make sure the whole clod of earth comes out of the pot at once, without having to for instance use a knife along the sides.
Squeezing the middle of the pot once or twice is usually sufficient.
By grabbing the pot from above and holding the plant between your fingers, you make sure the plant can’t fall out and the roots can’t get damaged.
Professional vegetable growers also use this method.
By turning the pot over, you make sure the whole clod is safely placed in your hand, in one piece.
Now you can carefully pull the pot off the clod without damaging the roots.
You can now put the plant in the new pot.
Make sure the pot is about halfway filled with soil and fill it up once you transplanted the plant.
What pot size
The size of the pots you use depends on the number of plants per square feet.
To get a maximal return from your light and space, I always grow according to the Sea Of Green (SOG) method.

This means that you place as many plants as possible to get a nice green blanket, and no light is lost by falling to the ground. As a rule, it boils down to this:
|SURFACE AREA||NUMBER OF PLANTS||POT SIZE|
|12 Square feet||9||5 gallon|
|12 Square feet||16||3 gallon|
|12 Square feet||24||2 gallon|
When multiplying the number of plants with the number of gallons, you’ll see you need about 45 gallons of soil per 11 square feet surface area for growing to make sure the roots can optimally develop.
This is also good to know if you’re using one large container for all your plants.
