Good stuff WH, I tried twice to get a recirc system to work but I have such a small space it is not worth the hassle - the tubing bends were too sharp and nothing could be moved around at all. Must have wasted $50 and a weeks worth of free time trying, but the space constraint kicked my butt.

Good news is that I have enough supplies to try it again once I reconfigure my grow space. But instead I have decided to try my hand at a SCROG, since that approach seems most well suited to my small area and 400W HPS lighting.

P.S. Love that Kushette left behind gifts for the holidy season... Stop by my new log sometime as I am just getting the BD's set to go into the area today or tomorrow.
