Remember the cheap greenhouse we put up to cover the aquaponics?
I thought an update was in order.
The 1500 gallon fish tank seems to keep the temp in the greenhouse from getting down to freezing.
The wife got some thermometers and stuck one inside the greenhouse, out of the light, and one in the shade outside.
Here’s outside, October 22nd at 10am…
I think the low that morning was 35 degrees, but it’s 40 degrees here at 10am.
Inside the greenhouse…
Just a touch under 55 degrees. That’s a really good sign. Usually the temperature in a greenhouse lags in the morning.
I have no illusions that the greenhouse will stay above freezing when it gets to be 20 degrees outside. What would you use to bump the temp up?
I’m not really interested in anything that burns. I’m also about 600 feet from AC power, so that is out. I do have 12 volt DC though. Maybe Christmas lights? (not LED)
Let me know what you think.
I’m not really worried about the freezing temps as long as the pump keeps running. I imagine the cold will start catching up with the batteries though.
