I use 33% Perlite, 33% Sierra Organics Potting Mix & 33% Sierra Organics Top Soil. One drop of Superthrive per gallon of distilled water.

Right now Ive got a 265cfm Dayton fan bringing fresh air in but no real exhaust fan. I figured the incoming air would force out the old air since I leave the door open during lights on. But I ordered a 6" Vortex that will be here this week and I'll set it up as an exhaust.

Based on some pictures off damping-off that I looked up on the net, it sure does look similar. I'll bake the soil before my next attempt just to be sure.

Thanks for the replys...
doco Reviewed by doco on . What Happened to my Seedlings? Ok, for the last week these seedlings have continued to yellow and stagnate, with little or no growth at all. I don't know if it's overwatering, underwatering, or heat. We've still had some 75 - 80 days here in SoCal. The PH is fine and I am using a single 95w CFL that puts out about 6000 lumens for this seedling stage. I intially had it only a couple inches from them but it seemed to get warm under the reflector hood (up to 90f) so I moved it up a couple more inches. Maybe these bigger CFLs Rating: 5
