Things are warming up quickly, but the nights are still chilly.
The temp in my greenhouse got down to 31 degrees the other night. I’ve been running a shop light in it, but it’s been making a 3 degree difference at best.
The first thing I thought of was adding some buckets of water. The idea is that the sun heats the buckets of water, the water slowly sheds the heat as the sun goes down.
I know that the buckets will release heat too quickly just using the sun to heat them. I was hoping the shop light would stretch their heating properties.
My next thought was to get the greenhouse warmer during the day, so that everything in the greenhouse would take longer to drop below 40 degrees.
I added a solar blanket.
I got this idea from a show called “Dual Survival”. The idea is that any radiant heat is reflected off the solar blanket back into the greenhouse rather than out the back side. These solar blankets are cheap. I ordered 10 for $1 each a year or two ago.
During the day, the difference was incredible…
The high hit 89 degrees within the greenhouse. The temp in the sun outside at the same time was 62.
Conditions still dropped too much at night. Unfortunately, this is a temporary setup. I’m not willing to invest in anything like a heat pump. I’ll have to use an electric heater if I want to keep things above 50 degrees.
