Hey Dude, I just watched the latest DGC video and thought of a way to conserve heat for a low cost on your future 5×5 grow in the garage. Layout a few rolls of R-11 or thicker “faced” insulation around your tent when it gets cold. For about $50 (USD) you can get 2-3 rolls of insulation, a roll of 8’x25′ black plastic and a wide roll of tape. The roll of plastic can be used to wrap the insulation to prevent any of it from becoming air-born.
Keep it Growing,
