Wow, that sounds very interesting. I wonder though how much to heat the water that runs through those copper pipes? I know someone who is very good at setting up solar systems, I wonder if something like that could work with solar during the day heating the water and a battery charged by solar could heat at night?
I know it's the soil that has to be warm for germination and the air can be cooler, Sure would we wonderful if I could actually propagate all my seeds in the GH and not have to have two shelving units in the house since we have such a tiny house! Did you get the name of the supplier for the bladders?
