Same, but I've decided this year I'm just gonna do a bunch of flowers instead of fruits and veggies. Just seeded 64 African Daisies, Mexican Sunflowers, and Carnations...and some hot peppers for good measure.

I'll say. I have a neighbor like this, he builds these elaborate things then never actually uses them for their intended purposes. He just likes to build stuff.

FWIW: Forget all that wood, it's a waste of time and effort. Make the base out of large diameter PVC pipe instead. Now you can pick the thing up and move it around, something you'll undoubtedly need to do ( it won't rot as well, and won't contaminate the soil as the treated wood tends to do ). The biggest mistake I see people make with these things is not siting them correctly to maximize the sun exposure. Coldframes work very well on their own, with a glass cover you have a mini greenhouse when necessary ( early spring ). Those you make out of wood, because nothing else will hold all the weight of the soil.

A wood frame is nice for attaching plastic, hanging pots and mounting shelves and doors. It's not necessary, though; you can always just secure the plastic on each side with a contractor bag of rocks (if you want to look like a meth-head growing dope in his back yard.)

Around here, bamboo grows like weeds. I came up with a design for structures using 4 ft iron U posts driven into the earth, with bamboo tied to the post with iron wire as the upright. I've built a 12x12x12 box covered with bird net for my fig tree to keep the starlings at bay. Trellis's for caneberries using same but iron mesh rather than plastic netting. As conditions change, you just pull the stakes up and reposition. Plus, it looks great.

PVC rots and degrades into chips and dust within 10 years of being constantly exposed to the weather, and the materials go right into the environment.

I'd hate being your neighbor, Oscar, watching your judge me while giving bad advice online.

Has this been your experience? Because while I use bamboo, which does rot after a few years and needs replacement, I have recycled PVC piping I found cleaning up the property that's been lying outside, in direct contact with the ground since the early 80's when the previous owner did renovation. It was a little dirty, but otherwise in fine condition.

And yes, you can join the club, most of the neighbors just tolerate us here. They cut down all the trees, pave everything, and park their fleets of trucks and recreational vehicles on it. So we're looked on with great suspicion because we have trees, flowers, and wildlife on our lot.

At first I thought: "OK a crapload of lumber and some PVC, no problem" then he went on about getting rebar and conduit. Then I realize, he just wants to buy as many different items as possible to make one greenhouse. I'm surprised it didn't include any drywall or spackle.

@meme
Tape or paint your pvc. Replace and recycle after 10 or 15 years of use. Total cost: $40-70 for a decade or more of use.

@chum
You can build a greenhouse like this without lumber, but I have no idea how you'd do it without rebar.

@ Oscar
I don't think I've ever seen PVC rot and flake. It definitely gets brittle if it freezes enough times, but I know for sure it can take more than a decade of use in sunlight.

I met a traveller from an antique land,
Who said—“Two vast and trunkless legs of PVC
Stand in the desert. . . . Near them, on the sand,
Half sunk a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them, and the heart that fed;
And on the pedestal, these words appear:
My name is Memedumpster, King of POETV;
Look on my Works, ye Mighty, and despair!
Nothing beside remains. Round the decay
Of that colossal Wreck, boundless and bare
The lone and level sands stretch far away.”

i wouldn't even consider embarking on a project like this unless I could incorporate at least one katana

I'm more kind of an idea-man?
