Light Green Stems

[Hapchu]

You really want to bury that stem at the min of 1" from leaves. This will help with the stringy stem.

Much appreciated, will do

CFLs, about 15 cm aaand I'm trying to get as close to 25-28° as possible but i don't have a thermometer so i can't be as accurate as i would like to

Keep in mind that the plant is a newborn, getting the light as close as possible should not be a priority imo but then again I don't use CFL's and don't know how much heat they generate at that proximity. High temperatures can cause the plant to stretch causing them to thin out and topple over. I'd support the stem as DemonTrich suggested and I'd try pulling that cfl back a it. I've seen new growth on my plant narrow dramatically when the temperature rose a few days I was away from my grow. Good Luck!
