Bottom Heat after germination question
Okay.. I know it is bad to keep bottom heat going after germination, and I always remove it.... but why?
My bottom heat is an electric blanket so I can turn it way down to maybe 70. I know if I keep it warmer, like germination temps., the little roots will burn and 'run' away from it.
If I keep the blanket on at 70 degrees, is this still a bad idea? I thought the plants may like the extra warmth because it helps keep the air temp 75 at night. Without it on it dips to 62-66.
What do you think? Has anyone else used mild bottom heat throughout the seedling statges?
