Hello all, I hope this is in the right sections.
I live in the eastern part of Canada and I am looking a. Building a hoop house in the spring 45L x 25W. Due to certain circumstances I can't build a permanent one, or 100% the way I would like. So I was going to just put up the ribs and throw some poly over it. Main purpose is to thaw the ground out quicker and be able to direct sow my plants earlier. Then I will pull the poly off come summer, until the fall and put it over to extend the season a bit. I wont be using it in the winter.
To create some thermal mass to help heat the hoop house I was going to build a rocket stove and circulate water, through a copper coil into some 55 gallon drums.
I would really prefer not to build a wooden end wall to vent the rocket stove out of. I would much rather just vent through the poly somehow without it melting and/or catching on fire. Any insight would be greatly appreciated. Thanks
