...just make sure you don't cook those lovely lil' darlins, cuz they're really really susceptible to it Don't ask me how I know this

The light they're getting is wonderful overkill, and your temp is basically right-on. If you can keep what's going into the soil at a ph of 5.7 to 6.2, that is also near-perfect. Not sure if you have any yet, but try to find a small bottle of SuperThr!ve if you can--the little ones love it, and it helps 'em get big and strong faster...

Start LST-ing 'em [gently!] when they're about four or five inches tall. Seriously

They love it. They're dirty girls, dontchaknow
