Cool idea.
God love ya cotton socks today 😁 just the info I was lookin for 👍👍❤
2 questions, first do you have more than one wall on the north side, like an inner and outer wall? And second, do you have video footage posted of the inside of the greenhouse (under snowload)?
More info on the transpired solar collector would be awesome! Haven't ever seen that in another greenhouse design. Are you fabricating that custom or using something like the Solar Wall?
will you use china green house style blanket system ? The pull a blanquet over the glazing for the nigth and pull it back in the morning to keep most of the heat and work like the snow you have now but while using the green house for production in winter time. There is motor and roll sytem on top of the green house for that.
Hi Rob, What is the marginal benefit of taking the the excess heat and forcing it underground using the tubes that you did when you compare that method to having a berm / clay wall / water filled barrels etc. (basically any sort of thermal mass) against the back wall? Is there any value in having both the underground battery like you have AND the back wall thermal mass battery, or is that overkill / inefficient? Thanks in advance.
