Sorry maybe that was badly written, I was wondering when was the best time to start 12/12, I have to white widow at 12 inches tall, they are in a hydro pot that raises them a foot of the floor, the room is 6 foot tall and using ez rollers to suspend.
With the lift from the ground and the distance of the light from the ceiling, what size should I grow to before inducing, I'm using a 400w sylvania grolux hps with a 600w ballast was wondering how high I should grow them before flowering to make sure they dont grow to big?
