This time on as the seeds grow

So it has been a few weeks since I started my tomatoes, herbs, peppers, broccoli, and spinach.  The tomatoes, peppers, and herbs are coming along nicely.  Broccoli is giving me fits, and spinach has flat out refused to come out and play.  Even though I had a grow light this year, my broccoli quickly became long and leggy, unable to support their own weight and flopped over.  From this point it is usually only a matter of time before they damp off and die.  I have repotted them and tried to bury as much of the stem as possible while lowering the light until it practically sits on the plastic cover.  The problem is I can’t take the cover off because the cats think I’m growing them a buffet and the plastic cover is a good 6 inches from the plants, preventing the grow light from being right over the seedlings.  It doesn’t look good for the broccoli.  The spinach has been reseeded and moved to the warm starter tray.  I’m not holding out much hope for either of them.
