Walker's Greenhouse Journal
|Reworked "environment control center". The fan/shutter control thermostat now has insulation on the top and south sides. During the daytime, sun shining on it would heat it up about 10 degrees above ambient temperature.|
The heater has also been replaced with a cheaper simple heater. The internal thermostat in the heater senses the temperature inside the heater, which is quite different from the greenhouse temperature. The solution: I added a separate heater control circuit, with a digital thermostat on the wall directly above the heater.
