Depends on how they are going to be artifcially lit or are you going to be keeping them in a sunny location? They grow fast and usually 4 - 8 weeks prior is fine. If you want then to be 12" my plants get to be 12" in as little as 3 weeks so.

Herbus Reviewed by Herbus on . Alright I gotta Question!! okay i just came up with an idea i could grow maybe 2 or 3 plants in this spot in my house until they were about a foot tall. Then i would take them up to this big hill thing up behind my house to put them(this would be summer). Its a good spot and nobody goes up there. we have very hot sunny summers most of the time . My problem is that it dosent have ALOT of percipitation i mean its not like a desert or anything it rains a decent amount. but would i need to go up there and water the sons of Rating: 5
