ill tell you what its all worth it though, because i only invested about 50 dollars in that whole system, i only had to buy the big cfl which was $16, the cfl flood light was like 6 bucks, and the hps fixture was 30 bucks. Im a firm believer in growing in soil too, i think that you can do just as good with soil as you can with a hydro system, i think the only difference is one takes a little longer. Your shit will come out just as good if you know what your doing. I know pretty much all there is to know, ive just never started them indoors before, my last one was brought in from outside cuz i wanted to keep it going cuz we got an early frost. Grrrrr Ohio gotta luvv the weather. But hell yeah it works real well and i didnt have to spend much $ so i cant complain. I did the math and all the lights together put out roughly about 30,000 lumens, I dont know how much of that it actually absorbes, but it definatly worked real well
