Hello! I just want to ask, - is it important that the sides of the plants get alot of light as well as the top? I have heard that just a light above the plants is all they need, but I have also heard, the more light the better. I am wanting to grow in a enclosed box, and during veg I want to put T5 2ft x4 bulbs on top and along the sides of the box, a couple of 4footers going vertical on the sides to keep the entire side of the plant lit up. Would this be worth it or a waste of time/money? Thanks!
