Seems I post this every day
Plants do not see light the way you and I do, in fact most of what they actually use we can't see at all, if your lights are the right spectrum they will grow
if you keep the plant healthy and green you can harvest in stages and increase your yields by as much as 30%
just because it looks like shade to you does not mean it is shade to the plant, ask yourself are the leaves at the bottom of a 30 foot tree any different from the ones at the top?
