In this article we will discuss the cultivation of cannabis transplantation technique. Although it is not exact, as different gardeners can use different techniques in different crops, based on the present moment and deciding what to do in every new crop.
Personally, I don’t transplant most of my plants; only those that I have placed small flowerpots and, those that, when the flowering time comes, require a change; even having replaced the substrate with compost and humus. Usually they are high sativa percentage genetics, since they require much more food than an indica genetics.
My technique consists of leaving an approximate 30 cm of free pot to be able, after the solstice, to place the plants new substrate made up of compost, mycorrhiza worm humus, trichoderma, microalgae, etc., so that the plant starts a next ‘happy’ cycle and does not stress due to the lack of food.
If you start with small pots with your cannabis genetics, we are going to see when a good time to transplant is.
It is recommended to do three transplants:
- The first one, when we pass the seedling to the initial pot.
- The second, when the plant doubles in the size of the pot .
- The third and last one, after the solstice. This will be the perfect time for the roots to expand better and achieve the perfect support for the plant to resist despite the weight of the flowers.
When to make them
As we stated in a previous article (biodynamic cultivation), if you want to follow a biodynamic crop, you will have to carry out these transplants in a new and growing moon, which is when the sap ascends to the aerial part of the plants. You must always try to do a good watering a little before the sun goes down; asmuch as is the ideal time to do so.
We must carry out this technique carefully, do not panic and try to remove the entire pot and place it immediately in a larger pot. After that, cover quickly and water again after having completed it.
If you do not have much experience and you damage the roots a bit, REMEMBER not to expose the plant that was transplanted to the sun, at least for a few days. If it became much stressed, and it has significantly decreased, keep it pulverised, hydrated and in a cool place without winds that could stress it even more.
The plant will most probably recover in a week and you will see how the growth returns to normal.
If you saw that it begins to die, surely it is because the main root has been affected and it will be your turn to start again.
Pots for transplants
For the first transplant, you can start with a 1.5 or 2 l small pot; then, 15 or 20 days when the plant doubles the size of the pot. Is at that moment when you can transplant to 7 or 10 l. pot.
After 20 or 30 days of this second transplant, the plant will have already generated a visible support and would have doubled the size of the pot again, this will be the last transplant to a 15 or 20 l pot. before the flowering.
If you cultivate indoors, the shape of the transplant will depend a lot on the space you have and the type of crop.
For a conventional crop you can make the first transplant when the plant reaches a height between 25 and 30 cm that will be between 3 and 4 weeks from germination, deciding the liters of pot according to the space. A second transplant should be done after 15 or 20 days and a final one before flowering, as in the case of outdoor transplants.
I hope this article has been helpful and that your crops are prosperous and get better and better.
