I have three girls in 3.5 gal pots that are doing well.I had them bunched together but they were getting to big so I decided to put them side by side and found that the outer two are really not getting a whole lot of good light coverage.I have the lights at 14 inches from plants and if I raise it the coverage will open up somewhat but the light intensity will drop even more towards the outer two plants.I,m a little disappointed that the coverage drops off that much so the only thing I can do is rotate them to the center so they all get the center stronger light.I knew before I bought it they said the foot print was about three to four feet but didn't think the intenseity would drop that much towards the outer edges.The optimum would be to have another light but there goes another four hundred bucks and that would be over 800.00 bucks to properly grow three or four plants and that seems kind of crazy to me.I guess ill just have to deal with it the best I can and maybe get another light down the road.
