Now that winter-grows are here, (in the northern hemi anyway). Has anyone ever used a heat pad to keep things warmer from the bottom up? Also has anyone used mirrors in the grow environment, tent, etc. ?
Would love to get some advice. The leaves are curling down and a bit squashed. Not sure if it's overwatered or something else.
