if two of them are already a foot and the smallest is eight inches, then i would go ahead and throw it into 12/12 now. i like to put mine in flowering stage around 8-12 inches as any more taller than that will give you too big of a plant as it grows way MORE during the flowering stage. you wattage of lights seem good to me, but you have to be more specific. what kind of 150w grow bulbs are those? what color spectrum?
kuri Reviewed by kuri on . When is it ok to go 12/12? I'm at 48 days since my first one pop out of the soil. It's an indoor setup and I got two 150w grow bulbs over head, a 35w grow-an-show underneith, and two 4ft. 40w flouro's on the side, one warm and one soft. I'm running 18/6 now. Is this enough light for a 3x3 area? When should I go 12/12? Do I need more light? One of them seems to be a dwarf. I am not sure what to do with that one. Two are about a foot tall. They seem to be pretty healthy. I was hoping for them to be a bit taller. The last Rating: 5
