This stuff was maybe a 6 mil plastic clear sheeting.
I was hopeful but it just didn't hold up.
How was the plastic attached?
the frame was mostly okay though, even being made of that shit plastic tubing.
I'm talking about the plastic sheeting.
So the frame built just like PVC would, and then the walls were essentailly a huge clear bag with a zipper around the front.
Wrapper? I dunno.
Hard to describe, like a skinn I guess.
was it a solid piece that was glued on? I'd use zip ties attached to each support post.
So you end up with basically a large clear box.
No, it was flexible plastic that the PVC "skeleton" gave structure to from the inside.
Let me see if I can find one, this was years ago and have since built something more sound.
Something similar in concept to this.
It's hard to describe without having pictures. It would be a pvc skeleton linked together with tees and pipe to make the frame work with zip ties through grommets in the plastic to secure the skeleton.
With thicker plastic and a zipper running around the whole front side.
Of course that would tear. It's like a giant sail that would catch the wind. It needs to have a bit of give to prevent it tearing.
Yeah, I kow exactly what you are talking about, I think it would be fine as long as the grommets were installed properly and the sheeting was thick enough.
Oh, it gave..
Storms get pretty bad here though with respect to winds.
I work in a hardware store that sells 8mm plastic. But for some reason I can't find it listed online.
yeah, you could try to attach the grommets to another piece of plastic and then glue that on to the sheeting.
That would probably work better. You would need a hell of a glue.
Some of that industrial 3M shit.
i'd lean towards a clear caulk.
I don't think it would stick well enough. Polyurethane caulk maybe.
Or liquid nails.
The plastic is smooth.
On second thought, canvass could be better glued onto the plastic without having to deal with the surface smoothness.
Well, it would still be smooth on the plastic side.
I wonder if it would be better to do it all in canvas and put clear plastic windows in it.
Would allow for venting to reduce wind strain.
you would glue the canvass first then let it start to dry (30%), then place the plastic and canvass in a vice.
I ended up just using this on a wood frame.
A full canvass structure wouldn't work. You need the light at all periods of the day otherwise most of the plants in the greenhouse won't get enough light to produce fruit.
Yeah, just make window panels. It would be fine.
Not as good as an all clear structure obviously.
I think in general it's better to use solid materials if you have the option.
You could probably get away with windows if you only used shade tolerant plants. You'd want plants that only need 3 or 4 hours of sunlight.
If I made one here with windows in the sides and roof, it would get much more than 4 hours a day.
