Transplant was a freakshow, the substrate came apart as the roots were not very big but they seem to have recovered already.
They are on 5L pots and Im thinking of growing them there until the end - I normally use 11L pots but would like to try reduce soil use, let me know if you think I will need the 11L instead, this is a closet grow and will veg them for 4-5weeks at most before flipping.
