one 1000w and one 600w covering a 5x5 tent? Is it overkill for that size of a tent? Right now I just have one 1000w(I feel like it doesn't cover the whole area) in my 5x5 but my next round I wanna throw in the 600w I have sitting around collecting dust. Planning on doing 9 plants. Any one tried this or have experience with it? What's the best way I could do this and what yield should I hope for if I do? I don't wanna do it if it's just gonna be wasting electricity. Any tips or pointers would be appreciated!
