starting petunia seeds
I was wondering if anyone could tell me what I should do with my wave petunia seeds. this year I tried something different and I started all of them in one big flat. On one side I have 50 purple and the other side I have 50 plum vain in the middle I have 50 coral. Both sides are up about an inch but the middle has hardly started.Should I uncover them and take them off the heat pad or will it be okay to leave it the way it is.Also should I put the grow lights on timers or leave on for 24 hours.
