doing a rubbermaid grow used one cfl for the seedlings just put in another one but need more i no setting up a carbon filter when i need to and ill set the exhaust up then right now its pretty cool with only 2 cfls.
They're looking prety good Bro.....Mabey just a little overwatered.....Do you have drainage holes in your containers...and how often are you watering????????
Try to let them dry out some between waterings....Like every three days, this will let your roots get a little air that they need and minimize chances of root rot........hope the info helps Bro........
The leaves that have curled prob. won't straighten out just keep an eye on the new growth. they should flaten out when opened up...you need to water until you see a trickle out of the bottom of the container....you don't want to underwater either....just try watering every three days for a while I think you'll see an improvement.........keep me posted........
