I am still learning this lighting deal . the evo 8 is made for a 6x6 in veg and 5x5 flower and I have it in a 4x4 .. I bought it so I had room to expand . I really been paying attention to Chas420 and  his grows. I need the space between my canopy and light so I am thinking veg short and flower under the net. Hopefully I want damage her to bad . Should be another learning curve. Don't know what ya can do till you try.. The only thing I regret is I am not in my 20's lmao
