Help With Lights.

I am an outdoor grower. due to a cold snap that struck right after i began to germinate my seeds, i had to start them indoors. so i planted them in egg cartons with drainage. the soil is about 40% vermiculite and 60% light, fluffy premixed potting soil. The plants are under 4 CFLs. there are about 33 seedlings. some are yellowing at tips. i have read that this could be due to the warm white CFLs. i have very limited growing space. I dont have room to raise the CFLs. If i didnt raise them but added some cool white fluorescents, would this solve my problem?

I am currently having the problem you are having and am also using an egg carton. I used starting soil and have used 2 cool white CFLs. They seem to be doing fine and should be planted some time soon. Good luck!

Warm white is more for flowering. Stick with some cool white, especially if they are still pretty small.

Do you have any pictures? As long as the heat isn't a factor, you should be fine. Do a test with your hand and make an assessment. If it is too much heat, then move the lights back a little. Good luck with transplanting outside.
