It gets better. If the temperature drops it turns on a heater. If the temperature is too high it turns on an exhaust fan. If humidity is too low it turns on a little pump to spray mist. If humidity is too high... nothing yet. For soil moisture it actives a water pump. I control the cycle of lights so I can change them*. |

Just machined this block of aluminum. The heater element is a PTC thermister. It increases resistance the hotter it gets, no matter how much voltage you pump into it, limiting the maximum amount of heat. (I.e. it can never catch fire) But, just like a space heater it needs a little fan to stir the air. I found an old PC fan. |
