Just upgraded from tent to garage, complete garage. Ya its cool and all, but cooling it, not so much.. Here are a few hacks ive deployed to help out.. Temps stay at 80-72 day night.. day cycle is ran at night, night cycle is 10am-6pm. first is a window ac i built a cover duct for with r type insulation board and gorilla all weather tape.. not fancy, but works and dehumidifies. 2nd is my auto watering ro pump.. built a stand with plexi glass and some 1x2s. drilled some holes for the tubing to run in and out, small pump with timer settings. currently being used to fill my watering cups during veg.. during flower i have a drip system. and last but not least, a homemade ceiling fan made out of a broke box fan. just took the casing off, tied it to the rafter with bread tie wire/aka garden wire.. made sure it was secure on each bracket so it wouldnt wobble, moves an insane amount of air!!!
