No burns on the leaves this moring, but to be safe I did the 'hand test' at the top of the tallest plant; and the heat felt a bit uncomfortable so I raised the light a few more inches.

I turned Leggy #2's pot around so Jr gets better light exposure (gotta love the names I ended up giving 'em! ). So far KC is still the tallest at 11" , Leggy 2 is second at 8.5", Leggy 1 is third just a smidge above 7", Stubby lives up to its name at all of 4" (considering I wasn't sure it would survive the original light fixture falling on it and burning it badly) and looks much healthier than it originally did (to my relief).

Last but not least, Jr is expanding nicely (sprouted several weeks after the rest, go figure), not very tall (1" if that) but the leaves are getting nice and big. Latest pics!
