More Seed Starting Talk

Lesson learned from last enough to buy a timer for my shop lights this year. Also needed some bottom heat. The directions I have say to give seedlings artificial light for 18 hrs/day. Should I plug the heat mat into my timer with the lights or should the heat stay on 24 hrs/day until germination?

I leave the heat mat on all the time, and run lights for 15 hours a day.

Heat needs to be constant. Lights are debated. Some use 12 hours, some 16, some argue for 24 hours. Experiment and see which works best for you.

All I can attest to is what I do: stuff in the greenhouse gets Mother Earth's time - approximately 12 on and 12 off when she is in a sunny mood and 16 hours of fluorescent when she isn't. Things in the house get 24 hours on. Works for me.
