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

2017-09-29 05:04:12 UTC  

Oh shit, What if we used chicken wire attached the frame with plastic over that?

2017-09-29 05:05:05 UTC  

That would definitely give it some strength. You could even make a few vent slits for wind resitance that way.

2017-09-29 05:05:42 UTC  

Yeah, I can't believe that I didn't think of it sooner.

2017-09-29 05:05:46 UTC  

How big are you trying to go here?

2017-09-29 05:06:22 UTC  

Actually now that you mention it, I know someone who has one with chain link inner walls.

2017-09-29 05:07:07 UTC  

He didn't use plastic on the outside though. I think it was a conversion from an old chicken coup.

2017-09-29 05:07:27 UTC  

Well at least 6 feet tall at the apex. I have no Idea how wide to make it.

2017-09-29 05:07:38 UTC  

How much room do you have?

2017-09-29 05:07:51 UTC  

1 acre

2017-09-29 05:07:54 UTC
