So the frame built just like PVC would, and then the walls were essentailly a huge clear bag with a zipper around the front.

2017-09-29 04:38:46 UTC  

Wrapper? I dunno.

2017-09-29 04:39:09 UTC  

Hard to describe, like a skinn I guess.

2017-09-29 04:39:34 UTC  

was it a solid piece that was glued on? I'd use zip ties attached to each support post.

2017-09-29 04:39:42 UTC  

So you end up with basically a large clear box.

2017-09-29 04:40:33 UTC  

No, it was flexible plastic that the PVC "skeleton" gave structure to from the inside.

2017-09-29 04:41:00 UTC  

Let me see if I can find one, this was years ago and have since built something more sound.

2017-09-29 04:42:38 UTC  

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.

2017-09-29 04:43:14 UTC  

With thicker plastic and a zipper running around the whole front side.

2017-09-29 04:44:31 UTC  

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.

2017-09-29 04:44:43 UTC  

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.

2017-09-29 04:44:59 UTC  

Oh, it gave..

2017-09-29 04:45:29 UTC  

Storms get pretty bad here though with respect to winds.

2017-09-29 04:45:57 UTC  

I work in a hardware store that sells 8mm plastic. But for some reason I can't find it listed online.

2017-09-29 04:46:52 UTC  

The problem with grommets is that they create "tear points" if they aren't crimped well enough.

2017-09-29 04:48:26 UTC  

yeah, you could try to attach the grommets to another piece of plastic and then glue that on to the sheeting.

2017-09-29 04:49:05 UTC  

That would probably work better. You would need a hell of a glue.

2017-09-29 04:49:14 UTC  

Some of that industrial 3M shit.

2017-09-29 04:49:29 UTC  

i'd lean towards a clear caulk.

2017-09-29 04:50:07 UTC  

I don't think it would stick well enough. Polyurethane caulk maybe.

2017-09-29 04:50:12 UTC  

Or liquid nails.

2017-09-29 04:50:20 UTC  

The plastic is smooth.

2017-09-29 04:51:59 UTC  

On second thought, canvass could be better glued onto the plastic without having to deal with the surface smoothness.

2017-09-29 04:53:51 UTC  

Well, it would still be smooth on the plastic side.

2017-09-29 04:54:26 UTC  

I wonder if it would be better to do it all in canvas and put clear plastic windows in it.

2017-09-29 04:54:43 UTC  

Would allow for venting to reduce wind strain.

2017-09-29 04:55:31 UTC  

you would glue the canvass first then let it start to dry (30%), then place the plastic and canvass in a vice.

2017-09-29 04:56:56 UTC  

I ended up just using this on a wood frame.

2017-09-29 04:58:11 UTC  

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.

2017-09-29 04:58:49 UTC  

Yeah, just make window panels. It would be fine.

2017-09-29 04:58:59 UTC  

Not as good as an all clear structure obviously.

2017-09-29 04:59:58 UTC  

I think in general it's better to use solid materials if you have the option.

2017-09-29 05:00:06 UTC  

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.

2017-09-29 05:01:04 UTC  

If I made one here with windows in the sides and roof, it would get much more than 4 hours a day.

2017-09-29 05:01:54 UTC  

So, a clear roof with windows every few feet?

2017-09-29 05:02:59 UTC  

Maybe, I'm not sure. That sounds about right.

2017-09-29 05:03:06 UTC  

MAybe every foot.

2017-09-29 05:03:17 UTC  

The sides would still have to be mostly plastic.

2017-09-29 05:04:04 UTC  

Yeah, probably not a great idea. Too much work. Just build it with solid shit..kek
