Here is our first winter blossom.
I received my heat exchanger yesterday. Today I went to Lowes and bought ½” PEX and hopefully all fittings I need to install this.
I had to vent the greenhouse the last two days. That is heat I will be able to use the heat the fish water.
Last night it went to 30 degrees outside the greenhouse did not go below 56.6 Degrees. I now have a weather station in the greenhouse that has a Max Min daily temp.
