Lookin' good. That's a nice tent, huge, lol. Nice little seedling there. Was it germ'ed on the MH? I've always had my seedlings get burned by the MH, CFL is what I like for seeds/clones. Either way, looking awesome. Nice set-up with the airstones, sadly, I bet there will be some lose in pressure and one airstone will output more than the other. I like either the circular ones(haven't used one yet, but they look just so perfect for DWC in a bucket) or the little cylinder ones, the cheap ass kind. They just work good and are cheap. Either way, lookin' fresh.
