the thermometers lowest reading is 20 degrees,
and that is what is lit up when i just had a look,
the thermometer iam using at the moment is a designed for a fish tank a sticky strip type, i just stuck it on the mylar made roof, i i hope that is not true temp, and just the temp of the mylar,
i was thinking to buy a little blow heater? but would that just dry the air to much?
please help guys wanna get growing soon as possable.
