Man I have struggled for months trying to keep temperature regulated and balanced using the standard aquarium heater for mono tub, and have found that room I am currently using tends to fluctuate between 10-15 degrees depending on outside temp so it created inconsistency inside Milo tube, which resulted in a poor harvest and irregular fruiting. After removing and using the digital heater I noticed way less fluctuation in temperature and waiting for fruiting to begin!! Midwest is the BEST and always on time!! Sincerely The PBR Street Gang.

Product works better than expected for the purpose I'm using it for. keeps mycelium the perfect temp for colonization in a cold environment.
