also when u say mulch, u mean using peat moss? The sand I used is brick sand off of ma job site. I also but 2" of 3/4 crush stone on the bottom of the pails then 1-2" of sand with the soil on top. I wanted perlite but none of the garden centers had it and they won't stock it for another 2-3 weeks. I called around to 5-7 different garden centers. Stupid question but what's "cal mag"?

With regards to lighting, I have to run fluorescents due to heat issues. Will 5000K be enough for veg? I know there are 6500k out there but I can't seem to find them locally. For flower it's 3200's right?
