The best time to transplant cannabis is in the early morning or late afternoon. This is because this is when the plant will absorb the most water during transpiration. Transpire, means “to breathe out” and it makes up about 80% of a cannabis plant’s needs every day. So for it to be ready, you need to wait at least an hour after watering your plants before transplanting into smaller pots/trays and then another 20-30 minutes after transplanting them into bigger ones with higher humidity levels (about 75%). If you don’t have these conditions in place, try waiting until midday or evening when there’s more sunlight around so that they can get enough light but not too much heat from direct rays since this may kill them off faster than necessary.
