DWC buckets are also great if you have a tall grow area (remember, the bucket stands over a foot high before your plant even starts). I have been growing 4 and 5 foot plants in mine under a 250w HPS (2.33' wide x 1.5' deep x 7' high grow area) and pulling 6+ ounces each time, and it's great quality stuff too! Like tinytoon says, pH is an important factor, as is a good air pump. :thumbsup:

Other than that, it's cheap and easy to maintain! :jointsmile:
