A Texas-Style Hoop Frame PVC Pipe GreenHouse

It’s almost Spring! Yes, there may be a foot of snow on the ground still. Yes, it may still be -10ºC. Yes, the ground may still be frozen solid. But Spring is on the way. Well, it may be a little while yet – at least, here in Alberta. But down in Texas Spring is just around the corner.

In fact, Big Jim just sent me a few pictures of the hoop-style greenhouse that He just built. Since many of you may be thinking about building your own greenhouse this spring, I thought I’d share Big Jim’s pictures and tell you about some of the modifications he made to my Inexpensive Hoop-Frame PVC Pipe Greenhouse. So first the pictures…

The first thing you might notice is that Big Jim has added some braces to his end walls. This is a great idea, since the ends tend to be pulled in by the weight of snow in the winter.

He also added some height to his walls. He’s a tall guy, so he’s used PVC pipes that were 22′ long instead of just 20′. Because of the extra length, He also used 1″ pipe instead of 1/2″ pipe to give it some more strength. Another change He made was to use electrical conduit clamps to attach the pipes to the base, as opposed to the strapping.

So this is what it looks like all said and done. He plans to grow tomatoes, peppers, cucumbers, some flowers and hanging basket plants, and he even wants to try some hydroponics. Perhaps I’ll get a few more pics down the road and give you an update to how things are growing.

Anyway, hopefully that’ll inspire you  in your own greenhouse building endeavors. I think I may even integrate a few of his changes in my own greenhouse. But all in good time – I think I’ll let the ground thaw first.

My Hoop-Frame Greenhouse In the Snow

Well, not that long ago I showed you that a hoop-frame greenhouse could survive a Canadian winter. I should probably add “so far” to the end of that statement. We had a whole pile of snow (by central Alberta standards) over the past two days and I was away and thus unable to brush off the snow that was piling up on my greenhouse. So I was a little worried when I looked out this morning and saw my greenhouse looking like this.

Buried Greenhouse

The snow had accumulated on the top enough to start bending the pvc pipes and the roof began sinking. This is what it looked like inside.

Saggy Greenhouse

On one hand, I was sad to see it getting squashed by the snow like that. But on the other hand, I was over joyed to see that although it had bent, nothing had broken! Everything was intact – just a little bent out of shape. So here’s another positive for using PVC pipe. It can bend quite a bit, still not break, and then resume it’s shape again when the pressure is off.

So I took out my shovel and scraped the snow back from the sides and brushed the snow off of the roof best I could. Some chunks were frozen to the plastic at the top, and I didn’t want to risk wrecking the plastic, so I left some up there. But the warm weather that will come eventually, hopefully, should melt that away.

While there certainly are some risks to this type of greenhouse structure (after all, I do live in Canada), and we’re not out of the woods yet (still six more months of winter… well, three at least), I still stand behind my PVC pipe greenhouse.

Can A PVC Pipe Greenhouse Survive A Canadian Winter?

It’s December 12 in Central Alberta. Last week brought a lovely little blizzard with high winds and a whole pile of snow and this weekend we are looking forward to -35°C. Yup, must be winter. So, I figured it would be a great time to check on my little greenhouse. You know the one – the hoopframe greenhouse I made out of PVC pipes and covered with woven poly. Some people weren’t sure it would stand up the the wind and the snow and the cold temperatures, but I was confident. Mostly. So I ventured out in the -29.9°C weather this morning to see how well things were standing up. Here’s what it looked like:

Greenhouse in December Not bad so far. How about the inside? One of the biggest concerns is that the pvc pipes would snap or would bend under the weight of the snow. One nice thing is that Alberta snow tends to be pretty dry, so it’s not usually as heavy as the snow in other parts of the country. Regardless, it can still be pretty heavy when piled up. Well, here’s the inside.

Greenhouse in December Things are holding up well. Nothing has snapped, there is no major bending going on – all is bright and well. And, for an added bonus (for what it’s worth), it was -18.7°C inside while -29.9°C outside. Still really cold – but certainly a wide spread (and this only at 10am – by 2pm it should be significantly warmer from the sun).

So I must say I am pleased. I think this greenhouse is my best to date and I am excited to get some plants started out there earlier than I ever have before! I’ll keep you updated!

Update at 1:00pm later that day:

Ok, now it’s just -27°C outside, but a scorching -10°C inside! That’s 17 degrees people! Does that not impress you? I does me. I’ll have tomatoes in February!… Well, that might be a little wishful thinking…

An Inexpensive, Hail Proof, PVC Pipe Greenhouse

I’ve finally built my greenhouse for my new garden. It’s a twenty by twelve foot hoop-style greenhouse with wooden ends and is covered with 11 mil woven poly. This greenhouse has some pretty cool features that I really appreciate, and I think you will too.

My third hoop style greenhouse

First of all, the poly I used to cover it is fantastic. It is a super tough woven poly that I got from Northern Greenhouse out of Manitoba. How tough is it? Well, my brother (who operates the Saskaberry Ranch near Sundre) just got pounded by hail last Sunday. The hail broke windows, shredded siding, and striped everything off of his saskatoon and raspberry bushes – but his greenhouse covered with this same woven poly was completely undamaged! Amazing! (I’ll try to post a picture if I can get one.)

Secondly, to eliminate wear and tear on the plastic, I covered edges of the wooden ends with copper pipe insulation. This foam protects the poly from the sharp edges of the wood.

Insultation on greenhouse

Thirdly, it was very inexpensive and easy to build. The lumber was under $100, the poly was just over $200, and the pvc pipes were under $100. By the time I got all the misc. stuff, I was still under $500 total. Not bad, eh?

My third hoop style greenhouse

Being so late I only got a single row of tomatoes down one side, but next year I’ll be bursting at the seams once again! If you want to build a greenhouse like this one, check out my previous post that gives step by step instructions for building this same greenhouse. Since I’ve improved the design since then, I would recommend the following changes:

  • Use wooden ends instead of plastic – and cover the ends with pipe insulation.
  • Use 11 mil woven poly instead of the 6 mil.
  • Put the PVC pipes on the inside of the frame rather than on the outside

Other than that, you should be able to follow all the other steps. If you do follow this design, be sure to leave me a comment – I’d love to hear (and see) what you’ve been doing!

Hoop Frame Greenhouse in New Zealand

It seems everyone is in the greenhouse building mode! Ok, well, maybe not EVERYONE, but many are. I’m still working on plans for my next  greenhouse, but until then I wanted to show you another greenhouse that was built from my plans in my article “How to Build an Inexpensive Hoop-Style Greenhouse“. This one is from Farshid out of New Zealand. It took him three afternoons to build (after work that is), and cost about $200 NZ – that’s about $137 Canadian.

Thanks Farshid! Looks great!

My “Inexpensive Hoop-Frame Greenhouse” Design in Nova Scotia

Recently I received a comment on my post “How to Build An Inexpensive Hoop-Frame Greenhouse” from Stacy in Nova Scotia. Using the design she found at AlbertaHomeGardening.com, she built a 10 x 22 greenhouse. I asked her to send along a few pictures and she did. So I thought it would be good to share them with you to show you another example of how you too can build your own greenhouse. So here is her comments and her pictures. Thanks Stacy!

Well, we just built this greenhouse, with a few changes, we made ours 10×22. We put a piece of strapping 2 feet off the floor running the length of the greenhouse to sturdy it up. We also used strapping in the top centre (instead of pipe and zip ties)attached to the hoops with the metal electrical bands , we got a box of 50 for 8$.

Nova Scotia Hoop-Frame Greenhouse
It was complete in 2 days! Its wonderful! When we bought our farm it came with a huge pile of electrical conduit, enough for 3 or 4 of these greenhouses. We plan to build another very soon. We couldn’t have been happier to find this design! Good job!

Nova Scotia Greenhouse
It is now full of many vegetables, flowers and herbs getting ready for the upcoming season.
Happy gardening,
Stacy

How to Build an Inexpensive Hoop-Style Greenhouse

One of the most valuable assets in my garden is my greenhouse. It has allowed me to grow plants that I normally would not be able to grow, produce crops that the season is not usually long enough to produce, and protect my plants from frosts, hail, or other severe weather that normally would have destroyed my garden.

But I don’t have thousands of dollars to spend on a greenhouse. I just priced out an 8’x12’ greenhouse for $3,500. I would love to have a large, professional greenhouse, but that simply isn’t financially feasible for me. So, instead I’ve found a way to make a large greenhouse that is functional, easy to build, and inexpensive. This article will explain to you exactly how to build a 12’x32’ hoop-style greenhouse for under $400.
