So if the ambient temperature in your room is 75F, where would you like to set the temperature under the plants? In this case the ideal temperature for the roots of your plants would be 65F.

keylime Reviewed by keylime on . Heat mat 24 hours a day? Just was curious what some of you others think about running a heat mat all throughout the cycle 24 hours a day. warm soil helps roots grow, with a heat mat the soil would dry out a little faster letting me water more, more water more nutes more roots = bigger stronger plants, whatcha think?
