Heat Mat 100-

[trippy3]

I just checked the temp inside my dome on a mat and it's
reading 100F, are they supposed to get that hot?

I'm afraid that's a little too hot, I try to keep around 65-70 deg, does it have a tmp controller?

No 80 max.. get a thermostat for the mat. Heat comes from the light too.

theres a temperature that chemical reaction happen best at, and it happens to be around 70-80f. after that, any hotter, the reaction breaks down. any cooler, the reaction slows down.

No. Just a cheapy.

Thanks. And also the humidity inside the dome won't get over 50%, wtf?

2 out of the 6 have popped up, so this mishap won't kill just slow down the germination, right?

Get one of these.

Stick it in, the soil temp and air temp can be way different.

Plus you can check the temp of your pot roast. Seriously you need a soil thermometer. Just another 20 dollar gadget.

OK after re-reading my post I guess it sounded a bit abrupt. Anyway just git yerself a decent soil probe thermometer.

Peace,

Agree, then I use a separate thermometer located where plants are to dial-in...I used to crack dome cover but now have a vented one.

try a heating pad on low under the sink. Works every time. A heating "mat" is just a fancy name for a heating pad you can get for 10 bucks..or you can buy a mat that obviously gets way too hot for 25. Hmmm. When it's easy, let it be easy.

I wanted to add that this is a great link.

I thought to suggest that the OP buy a Johnson Controls A419. We use these
in mycology to use temps to control all sorts of different action.
....but they cost easily twice as much.

Take care,

JD

P.S. Note though that one commenter on that site said that using that
controller took some tweaking.
