Seed heating mat

tgplp · January 26, 2011

Hi all! I'm gonna be using a heating mat to germinate/grow my seedlings. Do I only heat it in the day, or what? Any tips? Thanks!

I use them every year.

Keep it on until your seedlings sprout. It also helps to cover them with a dome, to keep the moisture in.

If you don't have a dome, a sheet of plastic wrap will do the trick.

Yeah, it is important to keep them warm day and night until they sprout and then to remove them from the heat mat so the roots aren't damaged. No light is needed until the sprouts appear.

Ok, thanks! I'll do that.

Once they sprout take off the dome or plastic and get them to lite so they don't stretch and get to leggy.

If you notice any fuzzy white growth on the soil, a mix of hydrogen peroxide/water spritzed on it has worked for me. I guess it was another thread where you mentioned you use potting mix instead of soilless mix.
