If you use a heating pad, place a towel or two between the plants (or clones, or seeds) and the pad, or even better...raise the plants off the floor, and keep an air-space between the pad and the pots. Monitor for a couple hours to verify it doesn't get too hot. The warmer temps will evaporate the moisture quicker, too. :thumbsup:

Raising them off of the cold floors helps. If getting too cold at night, you can reverse the lighting schedule, so lights are on all night during the coldest hours.
Rusty Trichome Reviewed by Rusty Trichome on . Heating pad for low temp??? If my air temp drop down to 60 or so would it be a smart idea to put in the heating pad at about 77 degrees fahrienheit to keep the roots warm and to keep them from going into shock??? what do you think and what do you do at times of low temps???
