Those lights are "Grow lights". They are more than enough for what I have going in there. I also have another light I hook up when things get bigger. One of those lights is a 400 Watt HPS, the other is a 400 Watt MH. I won't have all those flowers in there in a month, they'll be moved to the outside gardens. I used to use 1000 watt lights, and I still have them, but I decided to down grade, as the bills were a little high.
That light is perfect for indoor growing. Having both HPS, and MH, I have both red and blue spectrums, required for healthy plants. It's allot more light than you'd get from a window. If you got these lights, you'd have more than enough light to get your momma started. Just look at that corn!!! I can't beleive it either. It's my first time trying it.
