Heat mat after germination...?

Kenneth,
Depends on the plants. Anything that normally requires warm
temperatures to grow will do much better if you leave the heat on. For
example, I keep tomato and cactus seedlings on the heating pad until it is
time to harden off in preparation to moving outdoors.
As noted by another reply, plants that require cooler temps should be
taken off the heating pad after germination. For example cabbage and
primula.

Howdy,
I am starting some plants in a rather cool garage. I currently have
them on a heat mat to speed germination.
I want to know more about the effects of the heat from below after the
plants have germinated.
Generally, is it useful to leave the heat on? If not, what are some of
the likely disadvantages?
Sincere thanks,

Hi Beeky,
Thanks so much for your response...
I am having a problem with tomato seedlings becoming super tall
(leggy?) and wondered if that might relate to the heat issue.
They are still at the two-leaf stage but some are so tall and spindly
that they cannot support themselves.
Thanks for any further thoughts,
The symptoms are either from too much heat or nitrogen, causing them
to grow too fast, or not enough light------are they bending toward a
light source. I remove bottom heat as soon as about 50% of my seeds
have germinated.
