Hello everyone,

I'm doing a project for a greenhouse in which I'll set up an aquaponic system and Black Soldier Fly production.

I'm in a hardiness 8 zone so I'll need to do something to keep the temperatures stable year-round. The idea is to make a rocket mass heater to heat it up when needed.

The south facing wall will be double glass and the remaining will be build with two layers of wood with slip-straw in the middle for insulation.

There is already a topic about this project but I decided that this part of the forum is more adequate for the debating everything. If you want, you can check our previous conversations, and conclusions, here https://permies.com/t/21366/cob/Increased-insulation-Cob

I have almost everything figured out but I'm unsure about the floor. The frost depth here is something like 1 meter and the yearly average temperature is 9 ÂșC so I don't want my floor to have connection to the soil because I would be loosing heat to it. Being so, I have to make some sort of isolation. On top of the isolation layer, I wanted to make another layer with cob and use it as additional thermal mass but I'm having concerns with humidity going in the cob...

I also wanted to make some kind of blankets to cover the wall with glass during the night but I'm not sure what's the best materials and/or method to do it.

I'll upload a google sketchup of the greenhouse. It's very basic as I'm just starting to use it but it's enough to give you an overall idea.

Green regards!

Being a smart alec beats the alternative. This tiny ad knows what I'm talking about:
