Go ahead and separate them IMMEDIATELY! You dont want ANY of the roots to tangle. Also I would reccomend using a drop of superthrive for the transplant.
Good luck!

18.5 Gallons? Damn, only need about 4-5 at MOST!
Chronisseur Reviewed by Chronisseur on . transplanting..... not to urgent of a problem but in need of help. ok so I have 2 Jack Herer seedlings that sprouted about 2-4 weeks ago in 1 five gallon pot. So far they are nice and green and growing perfectly...definite potenial is seen in them. great drainage and nutrient rich potting soil has pretty much let them explode upward(already very tall and good stem strength). My question lies in the two 18.5 gallon containers I have waiting for each plant. What is the best time to transplant and what should I be Rating: 5
