Do you have to fight pH problems when dealing with coir? How do you keep the pots from floating when you flood the table? I plan on trying a traditional SOG, so I thought a 40 gal res would be best because I'll have multiple plants. As for the light, I was planning on picking up one of the new Mars Epistar panels, but then I saw the price. End of that story. I'm thinking king about the Mars reflector light, but regardless of what I go with, it will be LED. Nothing is in stone right now because I'm still in the planning stage. As for right now, though, all 8 of my beans have popped, an they'll most likely hit the dirt tomorrow! It feels good to be back up in AFN, and it feels good to be getting dirt up under my nails again
