Thanks for the reply Jack. Finally a reply from an elder statesman here, hehe. I have the homegrown-hydroponics.com econo stealth cab (I think its called, the $795 one that ends up being 1100 with shipping). Just had it for 3 days now though. Was using the "other top company's" (sunlightsheds.com) PC model for the first month of growth. Had the meager one gallon reservoir at 1100 ppm for more than a week. The aerator stone kept migrating to a corner. The PC was 20 inch high with a 50 watt hps. The cab is almost 36 inches with a 400 hps hanging down a couple of inches. Got root rot in the PC, which I cleaned out as much as I could. Will send a picture of roots, hold on. Okay, got em.

Hey this thing came with the lights coming on every 8 hours and then off 4 hours, breaking up the day into two parts. Could that be killing them? (I told you I was a newb). Thanks for your time replying. Wheezey
