good set=up with the bulbs. I would pack some more medium around the stems and gently tie down the stretchier plants-train em while they're young.And get those cfls to within a couple inches of the tops of the plants.This should thicken those stems up.Keep up the good work- your plants have a home now, make them happy in it.Good to see persistance, and motivation on your part- the keys to success. peace
