We had a cold snap this morning which dropped the temp down to 52 degrees outside. With the insulation in place and the greenhouse closed up the temp stayed a balmy 74 degrees.
Not bad for this amount of insulation, of course winter has not set in yet, so for added protection I have purchased a small ceramic based heater which I will use to supplement the natural radiant heat of the greenhouse. I also have purchased a digital dual 500 watt Titanium aquarium heater unit which will be placed in the Fish Tanks to regulate the heat during the winter.
Next up, the building of an Aeroponics cloner/seedling starter system.
