Looking great SL. You inspired me with your first LED log to buy a Pro Grow 400 and I like it, but my grow space is 4.5 feet X 4.5 feet and I don't feel like its adequately covering more than 2.5 feet X 2.5 feet. I hung the light in the center of my 4.5 X 4.5 area and I'm just not happy with its coverage. The plants in the 2.5 X 2.5 area are growing very well under the 400 alone, but I want to utilize my entire area. I have debated buying another 400, but I still don't feel like it will cover the space right. Any suggestions on how to cover the edges better? I want to stick with LED to keep the temps and electric bills down. I think maybe I should have bought a 550. I have thought about maybe some LED spotlights. I am also toying with the idea of running my aeroflo2 30 site which if I bought another 400 that would work perfect, I just haven't done hydro in a long time and haven't had much practice with the aeroflo. Also being as I grow in a tent I am restricted on height and the aeroflo sits at almost 2 feet tall with only 4 feet to the top of the tent from there. I would have PM'd ya but I couldn't figure out how to...
