Plant is late for 7 days, because after 3 days I transplant it from 6l regular pot to 12l Air Pot. Unfortunately it slow down growth. I see that about day 7 it is recovering and growth is getting faster. As I can setup power of light, I am using about 30W now. Grow medium is pure coco coir. I am trying to push growth faster by using light for 24 hours.
