Warm and dry till harvest. Ideas?

So my 2 girls in their 200 g beds are gonna have to be kept warm and dry as long as possible. Can’t drag them in and out of the garage to finish off.

Thinking of building a frame out of
pvc and covering with green house plastic.

Any ideas how to keep some heat in there? Let’s hear some ideas!!

Somebody bought a carport frame, I think he said he got it on kijiji or craigslist or something, second hand then covered it with plastic, like what you're suggesting. He said it worked pretty well. I think he was in Oregon. If I find the original post I'll link it, but it was at least a month ago.

You used mostly manure like me right? Because manure creates a lot of warmth by itself keeping the roots nice and warm. The plant material itself can go through a lot of light frosts and the most that will happen is the leaves will turn purple

I’m just north of the 49th and a carport frame might work. Nope I didn’t use mostly manure, so keeping them warm will be my biggest challenge. A cover will keep them dry.

Was thinking my coleman camp stove hooked up to a 20lb tank. Would have to dial in the temp for sure. But that would create some heat for them!!

My bad...I could have sworn I read earlier you were using a lot of manure. Yeah your plan should work tho

Added benefit of the camp stove is some CO2. I'm at the 43rd and starting to worry a little, only have 3 in flower so far, rest are pre or veg. Winters here start around Halloween so it's gonna be cutting it close but the PVC and plastic is my plan in about a month or so, gonna be to big to heat though.

I'm very new to growing, so what I'm about to post is probably going to sound stupid, but when I used to visit my grandpa in Mexico he would boil water to keep his plants warm. He also built a PVC tent/greenhouse for his plants. When you brought up the Coleman stove it reminded me of him. I bought him one for his bday a few years back before he passed and he loved it. I don't know if it helps you with the moisture from the H2o vapor , but I do know it heats up a tent/greenhouse.

In the Canadian Forces we used coleman stoves to heat up our ten man cold weather tents in the field. It should work really well for something the size of a carport or small greenhouse. One night out in the training area during basic winter warfare and you get to really love those things.
