In GB that would be considered a house extension. The cost would be astronomical and definitely overkill for a greenhouse. I personally wouldn't use polycarbonate for windows, it would be like gardening in a tent, no view at all. An easier way to deal with glass is not to cut the glass to suit the construction but to make the construction fit the standard glass sizes !

You have to listen 👂. He said glass is to expensive which it is, it's also more prone to breaking, has a worse R value, is much more difficult to install, and it doesn't diffuse the light as well polycarbonate sheets. IMO twinwall and triple wall polycarbonate is far more superior. Light diffusion and heat retention is a big deal. Glass is overrated.

@@riverrat8693 Thanks for sharing your opinion on that.

@@FrederickDunn lol sorry for being rude. I guess if money's not a issue some kind of double paned glass that diffuses the light is the best but it probably costs a small fortune but will last forever unless it gets w broken. Most commercial greenhouses just use polycarbonate ends and poly film tops.

@@FrederickDunn for cold climates triple polycarbonate is amazing. That's what I'm going to use to keep down on propane costs.

​@@FrederickDunn Yeah... Glass would not work in my area. We have hailstorms to be concerned about. It's much cheaper and easier to replace polycarbonate.

how did it go?

You are right about the uses and folding shelves. Most plants will grow faster with more light. Many are triggered by the changing seasons and lighting gives the gardener more control of the trigger. Lights are great for long periods of overcast weather and create heat when they are most often used (fall, winter) helps keep the temps up.

I build a Aluminum one like that myself I told my mother it would fall over again and again without more supported before she even had me build it. The structure clearly needed to be reinforced around it needed more Anchorage to the ground. I tricked her into getting a small amount of more materials so I could create Anchorage and designed connection points so I could build a supporting system. She never ok the adding of a support structure. Luckly once the roof was wiped out by the first super windy day as it fall apart like house of cards. Aluminum parts stay in place but were extremely warped. The panels went flying through the air like sharp knives it was so luckly they were all stabbed to the trees or the ground when all was done because as fast as they were fly about they could have easily kill someone. I watched from behind a impact resistant window as it just came apart. My mother sadly never developed any structural common sense and just keeps repeatly making similar mistakes. She once tile over a porch that was basically nothing but rotten wood after she was told it was rotten wood was completely unsafe and needed rebuilt. She reply by jumping up and down on the porch and said why am I not fall through the floor. It was a pure mass thing because the original supports were 6 by 4's and every time she jumped they fall apart more which was leading to a catastrophic failure. When her tile started to crack apart as the supportive structure give way I rebuild it from the bottom crawling around under the floor with limited space. I use carjacks on cinder blocks to level and support the floor as I rebuild the floor. The floor have a layer of wood boards and a layer of concrete boards as built new concrete supports to support new wood framing that was completely independent structurally from what was previously supporting the floor. Now once the bad wood fall off nothing was going to happen but the need to replace a few face boards which were looks only and would be a cheap easy fix. One she never let me do. How the porch was even supporting any weight was a shock as you could pull pencils through like 75% the wood with the strength of one finger and it wasn't even hard at that. I told her when all was done I could have built her a whole new porch faster and wouldn't have costed much more. It all makes for some funny memories in the end because no one got hurt. I think my parents being so bad at builting is what made me so obsessed with it really. Do you live in Florida near tampa? because by brother is a contractor and depending on your budget maybe we could help you out.

У нас в Сибири , 1 кубометр кедра стоит 200 € . Не знаю дорого это или нет )

lag bolts and washers

This structure is highly overbuilt and impractical - the world's most attractive and expensive potting shed.

anything?

I purchased fans from Amazon. AC Infinity for the exhaust and simple deluxe for the circulating. Can't speak for the quality or durability, since I just got them.

thank you very much .. really appreciated, please keep posting updates.

was wondering this as well

Few weeks to build lmao

Lmao. For reals. I Said the same thing too

better than the place I live😂

Right? Hahahaha

😂 lmao

Overall dimensions are 10-ft. W x 14-ft. D x 12-ft. H. You can get more details about the project at www.familyhandyman.com/project/how-to-build-a-greenhouse/

I figure an arm and a leg, and at least a kidney.

About 2000 $

I'm building it now. Looks like it will be $5-6K. I used treated pine instead of cedar for framing and Hardi Board instead of cedar for the knee walls. Also used Gallina polycarbonate panels instead of Lexan, an equivalent product that is less expensive and made in the USA. I ordered 18 sheets of 4x8 panels and used it all.

@@tundradave138 oof thats expansive for that little of a greenhouse.

I have the magazine issue of this greenhouse and they said about $10’000-$14’000 depending on material prices. That building it the exact same way with the rock foundation base.

About $5-6 K for me. See my comment above.

I was wondering the same thing and can the panels be easily replaced if the snow crashes them in the greenhouse. Can the panels be replaced easily without taking the whole greenhouse apart ?

I wondered if a bit of triangulation on the walls, and on the roof too, would be a good idea. Nice job though.

I added wire rope and turnbuckles diagonally from the sole plate centers on the long walls to the top corners at each end. Also ran wire rope from the top plate centers to the top of the trusses on each end to stiffen the roof assembly.

@@tundradave138 awesome, thanks!

Nothing lasts forever. BOW DOWN TO THE TRUE!

How much did yours cost to put together?

@@hadleighnelson1812 I picked the materials up when the prices plummeted, I think I was into it about $700

There are many ways of treating wood to improve resistance to moisture. Some are extremely toxic, others less so. Unless you know the wood was treated in a way that is nontoxic, trust the manufacturer, and trust the seller, you should assume that treated wood is unsuitable for food growing.
