in this link of the green house http://www.i4at.org/surv/green.htm

I am going to be puting this together this weekend

I am using 3/4pvc pipes and I plan on making this only 9 to 10 feet wide instead of the plans 12 foot directions .

I am doing this because I want more hight and I don't really need the width

Has anyone done this yet? And if so was there any problems doing so?

I plan to take some photos of my adventure so stay tuned

Jim (opps typo not Jin )

Jin,

I looked at those when I was considering building my greenhouse and decided against it because it wouldn't support my snow load. I opted instead for a cattlepanel hoop house which was very easy to build. I don't know how much snow or ice you get in your area but do take that into account. Some folks have also said that a lot of rain can bring the roof down on a regular hoophouse.
There is a whole thread here on the cattlepanel hoophouse you may want to check out before you start.

Good luck.

Thanks MolllyD

I know I am not going to have a NY style snowfall here, but it is not out of the question for us to get a bunch of snow. Ice storms are more common here for us, it can be 20* and raining here while on another day it can be 38* and snowing up a storm too.

I have already collected my parts for this hoophouse. I was more woried about changing the width to make it taller, I was also thinking that I could build a 3 foot tall wall on the north side and keep everything skewed some. ( not sure if I said that right)

Thanks again

Jim, the only thing I might worry about is additional stress on the PVC at the peak of the house, given the fact that you are bending the ends closer together (9-10 feet wide instead of 12 feet). You could possibly address this by threading a 3-4 foot long piece of rebar into the PVC at the apex to stiffen it up.

I have read that a coat of latex paint on the PVC where the ribs contact the film will keep the plasticizers from breaking down the poly.

I then built the frame out of some pt 2 X 8 I had laying arround the yard. I made the frame 12' 3" ;long X 8' wide .

It is good to use your tape measure to check the length of the distance between the corners to make sure the frame is square. Make sure you nail some braces on the frame to keep it square while you level the frame.

Thanks for the nice comments

this is really just a temp building for me
as soon as sping makes it way here I am going to plant them palms
and If I have to rebuild the end walls every year so be it

maybe next year I will build some side walls to set this on top of to give me more head room

"I have used mine sucessfully for 4 years now"

Mine is 18' x 20'

I am doing this because I want more hight and I don't really need the width
"i use a coupla 2x4s to help support mine" 14inch snow last year still standing"
Has anyone done this yet? And if so was there any problems doing so?
"i would suggest regular 4 year greenhouse cover worth the time and money. cover the pvc with duck tape (easier than paint).
I plan to take some photos of my adventure so stay tuned

When I first started my nursery I made several cold frame (PVC) green houses. I'm located in GA and just a inch of snow turned into a disaster of collapsed. The next summer I then reinforced my PVC by running rebar in the pipe. The next winter... complete disaster once again and thats even beating the snow off the greenhouses with a broom multiple nights. LOL I then gave up and went ahead and bought multiple steel frame greenhouses, problem solved. Now, I still to this day do have smaller 10'x30' green houses that are PVC but anything larger will not hold, even with out snow, the pipes become to brittle in the winter cole. GOOD LUCK.

For cattle panel hoop houses, has anyone built a short wall -- maybe 3' high -- to start the panels from there... giving you more hieght inside...?

Kind of sort of... we built the short 5 foot walls out of cattle panels and then put an arched cattle panel roof. I wanted the height for potted brugs and fruit trees. I used it for quite a few seasons till my sweetie built me a new greenhouse.

This is a link to the cattle panel plant shelter in my journal. http://davesgarden.com/community/journals/viewentry/115015/

If I can add... I covered it twice with 6 mil plastic. When it needed recovering for a third time, I broke down and purchased a SPF rated plastic which lasted till I moved in the new greenhouse and dismantled this one. That was money well spent considering the time and trouble to rewrap it. Kristi

Here's a recent photo of my new Barn style PVC greenhouse during construction
less then 10 days ago. We had a early winter storm that gave us 12 inches of snow.
Had to build something fast to protect our planters.
