Sturdy Glass Greenhouse for Backyard

Due to the animal situation, we are puttiing up a greenhouse for our hot peppers and vegetables this spring/summer. We are on the lake in Toronto, so it gets pretty windy and we want glass walls and dark brown or black aluminum frame for the look. It will be standing on a solid azek deck and we prefer about 8x8 to 10x10ft in size. Anyone have recommendations for where to source one? The price ranges online are enormous and we don't mind paying for good quality, but wanted any leads from fellow smart frugal people.

For the best deals check out Harbour Freight in the US.
A couple of friends of gotten some really nice units there the last 3-5 years.

How is it's quality? I see the prices are low, but there are very conflicting reviews. I need something that will withstand wind and a lot of UV/moisture. Is it glass or polycarbonate? I'm looking for completely clear walls.

It's polycarbonate with a corrugated style. It's not completely clear like glass, more like a bit of wax paper, if that makes sense, but not as extreme as wax paper.

I would build one out of old patio doors. Paint the vinyl or trim the whole thing out in cedar. Patio doors are good quality glass and somewhat structural. Plus old ones are free from door places.

I have known people with various types of Greenhouses...
Like everything else it comes down to Quality usually costs money

The best by far are permanent house add ons with either a full on sun room build on, or a lean to add on
Most of them are real glass ... or sometimes good quality acrylics

https://en.wikipedia.org/wiki/Sunroom#/ ... meter).jpg
https://lifestyleremodeling.com/do-it-y ... room-kits/

After that ...the standalone greenhouses
That come in various sizes and materials

The Palram ones fill the middle category * ... they are ok
With their acrylic / plastic panels (Although many aren’t clear, but more opaque)

https://www.thebay.com/palram-8-ft-x-4- ... nhouse&N=0

https://www.thebay.com/palram-hybrid-6- ... nhouse&N=0

But they perform iffy when it comes to weather / wind & snow load

So just like the truly portable ones, that are made with plastic sheeting that zips together like a tent

https://www.thebay.com/upper-bounce-ext ... nhouse&N=0

It’s best to either put them up / take them down annually

Or else, just remove the panels for the winter

At the bottom end, are the aforementioned portable units ... and anything on the much smaller size

* Harbour Freight brand is new to me. I have to say I was impressed with the reviews I read, especially the snow load pics.

Lol, still want a Greenhouse for my own gardening interests.
Currently leaning towards either INVESTING in a Lean To Add On
Or
Just getting / building something portable ... preferably one I can use indoors in the off season too

Maybe something like this = https://www.globalgardenfriends.com/201 ... d-windows/
Or this = https://vegocracy.com/diy-mini-greenhouse/
Or even this = https://www.instructables.com/id/Greenh ... d-Windows/

I got lots of retirement years left
So lots to explore, as Gardening is a great summertime hobby
And a decent source of fresh foods that saves money ... if you do it on a large enough scale

I've looked at some hobby ones from Palram and Outsunny but I have a feeling they won't withstand my elements. I'm thinking I need to pay about $3000 to $4000 for one with real tempered glass, high snow load and wind rating, plus I'm super particular about the look so it blends in with my yard decor. I do not have the time nor inclination to disassemble for winter and I like the idea of using it as extra storage. I also don't plan to move for over 20 yrs so absolutely don't want to assemble one more than once. I found this company very helpful and they said they did the greenhouse for CAMH hospital with the dark brown aluminum I want. Their shipping fee of an 8x8 glass traditional greenhouse kit would be $675 though. Not cheap.

Any feedback? http://backyardgreenhouses.ca/

Just came back from a trip up north and met a local farmer who had just installed a 20"x40" greenhouse on his property. It was basically a small barn with corrugated plastic walls and roof. Not clear like glass, more of a honey coloured quality. He said it maintains at least 8 degrees celsius on all but the coldest, sun-less days. I think it was called SUNTUF. I have no idea about the structure itself but this thing was soliddddddly built. It was beautiful and was incredibly warm inside while it was -20 outside the day I was there.

I have looked at their website before. Nice assortment of options.

Their website lists some jobs they’ve done In Canada (and the USA for their .com site)
Proud Supplier to: Government of Canada; The Waring House Restaurant, Inn and Conference Centre; Governor of Maine, The Blaine House; Shorter College; Government of USA; Bureau of Indian Affairs; Make-A-Wish Foundation; University of Hawaii and Several School Boards
Depending on where you live ... guess you could go take a look or make some calls

An 8x8 tempered glass green house would be extremely heavy. I can imagine shipping will be very high.

Hi,

Glass paneled greenhouse...haven't seen one since I was a child. When glass panes weren't available anymore, all the commercial farmers used corrugated fiberglass panels to cover their greenhouses. Don't know if you can still get corrugated fiberglass panels in Canada, might have to use polycarbonate panels.

I built mine out of SUNTUF.
They have clear panels available at Home Depot and Rona.
The coloured panels are more for applications where you don't want full sun in terms of heat buildup.
Palram makes SUNTUF.

I have an older version of this greenhouse in my yard. I've had it for about 6-7 years. It is located next to a black walnut tree, so not the best location for glass. It has been flawless. The panels are in fine shape, weathered, but fine. Frame is pretty much 100% as new. Only issue is the clips that hold the panels in (which this model seems to have solved) break every 4-6 years. But they gave a bunch of extras, so hasn't been an issue. I recommend it for cheap. Now if you have the space, you really should go polytunnel size. I find that I max my greenhouse (6*8) out way too quickly.
