How to Build a Greenhouse 

how did it go?

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.

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 !

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.

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.

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

was wondering this as well

lag bolts and washers

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.

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

Few weeks to build lmao

Lmao. For reals. I Said the same thing too

better than the place I live😂

Right? Hahahaha

😂 lmao

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.

That was my thought too. Bunnies, mice, and ground squirrels would help themselves if that was my base.

I used stainless roofing screws with the large rubber/metal washers. Also used H connectors and snap H connectors to join the panels to allow for expansion/contraction. I used galvalume steel building corners for the fascia on the gable ends and the corners of the polycarbonate walls. No maintenance on these products. I eliminated most of the bare wood. Used wood on the knee wall corners as in the video and wood door facings. Hardi Board lap siding on the knee walls. Used treated pine for framing and put waterproofing stain sealer on the knee wall wood corners and the framing just for looks. Hopefully it will retain the color for a few years and not turn the weathered gray in a couple of years.

Not cheap you can trust in that BUT, long lasting quality means you’ll likely do this only once in your lifetime!😁

8,000-10,000 is what it said in the magazine.

@@caidencondon3171 just got my copy…haven’t had a chance to read it yet. I figured that’s a safe bet, especially with todays lumber prices.

@@caidencondon3171 my buddies saw mill is itchin to cut the lumber for this…maybe in the spring…

@@caidencondon3171 That's even more expensive than my expensive guess.
