Also, for about $15 you can order a pint of both DynaGro Grow and Dynagro Bloom, which contain everything you need for a successful grow, including the trace nutes. It's cheap, easy to use, and you'll have enough to grow and harvest quite a few plants, so is definitely worth considering. If you do end up buying some, get some PH Up too,(also on Ebay, and pretty cheap) because the ferts will need adjusted before using, as most do.
