Germinate in paper towels; is heat necessary?
I remember germinating seeds in paper towels in a baggie, and when I read here about people doing it, I decided to try again myself this year. My question - once the seeds germinate and I plant them into starter pots, will they need additional bottom heat? I don't usually heat seedlings for long, as I don't want them to get leggy, but I'm not sure what to do when the seedlings are so small.
If I do need to heat, do you heat for just a few days, or ...???
Thanks for the help!
