greenhouse Greenhouse crashed

hot stuff

Well the 30+mph winds crashed my pvc pipe/9mil green house. I had the 9mil attached with lots of 2" binder clips. Obviously, that is not enough.

I'm using 3/4" pvc pipe for structure. I've heard of people making large clips out of pvc pipe to attach their plastic sheeting. Anyone know what size I'd need for 3/4" pvc? How wide would I have to cut out so it would go around it and still not pull out easily? Any suggestions would be appreciated.

Thank God I didn't have anything growing in that one yet.
 
The same thing happened to my PVC pipe greenhouse a couple weeks ago.
I went out and found a small 6x4 steel frame greenhouse for $140.00(AU)
Tethered it to the ground at each corner and put 3 10kg weights on various
parts of the frame to make sure it wasn't going anywhere.
 
Mine didn't go anywhere, the uprights were attached to my deck. But all the plastic popped off. If I get the plastic to stay on, I'm in business.
 
so its just the plastic sheeting thats giving you trouble?

i assume something like a washer head screw is out of the question?

ahh my joints actually popped because of the wind pressure on the end of the frame pushing it beyond it's limits until it cracked.
You can buy eyelets. that fix to the plastic then you just punch a small hole through the eyelet with a piece of wire or screwdriver. put one of these each side of the uprights and fix it directly and tie it to the frame.

I couldn't recommend where to get them from because I'm not in the USA but i first seen them on an american youtube video.
 
Easy for me to post advice after the fact! :cool:

Buy some 2x4's, drive them in the ground or dig out a hole and fill it with concrete, use six-mil plastic and laths to keep it secure! I built a large part of mine using windows people discarded. Added a layer of plastic on the inside to provide a vapor barrier which kept it warmer.

Mine is 12x16, eight foot high in the back, six foot tall in the front. I think I spent about $300 total but a sizable amount of that was for insulation and Mylar for the north wall.

Laths?
 
if your PVC tubing is 3/4" ID, check the OD...then check the 1" ID and I think you will find that the 1" is a pretty good fit...use a lighter schedule PVC if you can find it to make spreading it easier...or you can use a lot of shorter pieces...
 
Our "polytunnel" is a tad more open than yours, and we have far stronger winds to cope with ;)

This is a crappy pic but should give you some sort of idea ... basically our plastic cover is pulled over and fastened with roofing battens along its lengths.



Note : we did manage to share the cover with the neighbours, whilst also destroying 1/3 of that greenhouses structure, when we forgot to brace the woodwork and got hit with winds gusting 100mph :S

quick question...
do you typically position position a greenhouse solely with respect to the sun? or do you also take into consideration the local windrose to get better airflow?

In our case the orientation is dictated by the shape of the land ( suits WE orientation ), the worst winds we face are WSW. Ideally we'd have oriented NS which would suit both sun and winds.

I didn't have much choice - I had to build mine facing directly south! My north wall is all wood, lined with R-30 insulation and covered with Mylar.

that's very cool. almost looks like you could drag along flat ground.
did you build it yourself?
you guys ever think of installing gutters on these to collect water in a barrel?
