Greenhse poly/plexi/glass: which is optimal?

No, in short. Many balls in air: gardens need winterizing, so mulching and planting, replanting; digging a root cellar; getting in firewood. Tho have put more work in on it. Had a like jillion screws to get out (w/ screwgun) of where the plastic is to go down. Weeded out the raised beds for most part. Seems easier to do that before layering plastic. Coming around to getting down to that great moment of greenhouse covering. Within a few days, i 'spect. TY, will look in to the squirrel fan too. Hopefully can run one on solar. In the meantime I plan to leave the second layer like short enuf to allow incidental air circulation, failing a solar squirrel easily materializing. Happy Winterizin' , Nick

Yup, same here. No time....

Hmmph. Got the 1st layer up. Then considered putting the 2nd layer on the outside of that just atop those thin slats, but that would've left me if an inch between layers. Not even a squirrel fan would keep layers separated under snow load. So we decided to put a layer up on the inside. We had to take out the 2 lateral stabilizing boards and work vs. gravity, then the "fun" began. One mistake after another -- tuff shallow learning curve. We thought we'd get a better seal to put the inside layer up in one piece, measured as 22'x16'. This was after the inside layer on each end was already added. Then after our 1st hard lesson we figured to fold it in half, but slats in and tack up the top peak first, leaving 11' on either side. Then we thought to go from a corner. Now we've learned better and use the 1st learning as template for the next phase. So tomorrow I'll start in the middle being able to see that each side is straight and has enough poly to stretch to the corners. Hopefully that'll work. It's been a frustrating day. I do like the straw we put between the raised beds and the poly. Hopefully we can use it overwinter with the right carbon to nitrogen mix in the beds to trigger composting process. Fingers x'ed.

Looks good tho, even if it's a challenge.
