What kind of light are you using?

Keep the light(s) as close as possible without burning them. Just lower the lights gradually over the next day or two. I keep my seedlings less than 1 inch from a 20w CFL (one bulb for each seedling).

You should also get some kind of fan in there to make them sway a little (not too much!) and that'll help to really strengthen up the stems.

Happy growing :jointsmile:
