Mushroom farm 1.2 is doing great. I built this little fire hazard a few days ago to modulate the temperature inside the grow tent between 65 and 75 degrees. Then the lights and heater shut off over night, letting the temps drop to 50, spurring the mycellium to grow mushrooms when it warms up in the morning.
I was worried that the heater would tax the humidity automation, but the way I designed it, it actually evaporates water that collects in the tray that was overflowing. Win win.
