Anything the government gives you was first stolen, then leveraged with the central banks creating generational debt. Innovation stems from individuals having property and a little capital to play and try things.
Is there a quantitative snow load that this is designed for for instance 25 psf? Standard dutch houses are only 18psf and rely on snow melt systems even when there is 1m plus snow depth.
I just can’t get enough of this video. I want more. The great thing about this model is that it is one specific set of solutions. It’s a system, the whole thing. I would think it would be a great service to revisit this conversation and go into detail about how to order this green house, what options are there? Is the language barrier a problem when working with chinese distributors. What company in China has this speaker worked with and go over prices. Then discuss construction details and overall costs. This speaker should then offer consultation services for profit to help others get setup. I think this is a gem. There are thousands of greenhouse solutions but not a lot of complete, comprehensive, fully tested and matured systems. Great Work!
Thank you for sharing this. I am particularly happy to see the performance of this greenhouse. We built a passive solar greenhouse last fall based on the Verge Permaculture design course and we are looking forward to the first plantings very soon. Jianyi is demonstrating the way forward at a commercial scale. By comparison to China, we are clearly far behind where we should be. The lesson is clear, especially important in a province which has been so reliant on fossil fuels in the past. Thank you, Jianyi.
The key to better food in Canada in the winter isn't just passive, but passive design WITH a cheap heating solution. By doing that I believe we can change where most of our food comes from.
The cheapest heating solution is to use the sun, the free solar way. Mr Dong demonstrates clearly that heating with the sun is not a problem at all during the day - it is too much and he has to ventilate to keep the temperature down. The problem is the night temperature is too low, even with all the effort that he puts in, he still have nights that are below zero when it is very cold and cloudy. So the solution is crystal clear: transfer the extra solar thermal energy from air to water and store it for night use. Also insulate properly so that no coldness can come in. As simple as that. This is not rocket science. It is a common sense thing.
The cheapest heating would be to use mirrors to get more sunlight onto the greenhouse. For example, aside the blanket, you could have an extra roof on some hinges which instead of foil have stainless steel sheets installed in the autumn/fall, which would be raised during the day to concentrate more sunlight onto the plants. The sheets could be mounted on a sliding system for storage, so they can be packed away when there are strong winds during the day, so it doesn't block the greenhouse and also doesn't have the risk of being broken by the strong winds. There is also the option of using solar collector-concentrator lines to heat up air which is circulated by a fan, to keep the temperature inside even higher. The fan used to circulate the air could also be powered by a solar panel. Solar panels with some batteries could be used to power a few LEDs at night, for the plants to keep growing even then, and undervolting modern LED lightbulbs makes them a lot more fuel efficient and a lot longer-lasting. For the solar heating with air pipes, you can watch the video "Very cheap ( $15-40 ) solar collector-concentrator that does not need a tracker" by "Sergiy Yurko" on youtube. Even just having a simple raised roof at some 15-30 degrees from being vertical (the angle of the roof depending on the angle of the sun), on the side of the thermal-storage wall, angled towards the other end of the greenhouse, and using either stainless steel, or roof metal with spray-mirror sprayed on the side facing towards the greenhouse. Adding 20% to 30% more sunlight might be a great deal, for the price of building that metal-mirror roof/wall. And it can be mounted in a way which makes it fold towards the greenhouse when there is strong wind, where it can be clamped for extra safety against wind damage.
@@SimpleTek Not true, as long as you combine solar heat with geo thermal battery, you can solve that problem. Ross and Kat Elliott in Ontario demonstrated that, most people did not see how deep they dug into the ground to prepare the foundation for their SolaRoof greenhouse. They can grow vegetables when the outside is -30C
This year I am building a below grade submerged passive solar greenhouse with geothermal & compost heating in central Alberta. Thank you for this video.
I have been using chickens in greenhouses for 30 years to control bugs and the diseases they spread. The birds can go into a given area between crops for a week or two. The first thing they do is look for bugs and their eggs then they will eat crop residue and weeds.
Thank you so much. I'm in Denmark at 55.4 North, and I was looking for examples of passive solar greenhouses this far north. Yours is the perfect example, and your generous sharing of details, both when it comes to construction details and when it comes to what to grow when, makes it the best presentation I have seen so far on the subject. Thank you
Be careful of the different light levels! Calgary has nearly 3x the December sunshine as Copenhagen. Good luck on your project, and let us know how it goes!
Very interesting !! I think it is gonna be a great opportunity for Alberta to offset imports from US and Mexico. I like backyard vegetable gardenning in Calgary. Since 3 year, I have been planting more than enough leafy vegetable and little bit of tomatoes needed for my family during summer. ...Possibilty is there even for winter. Thanks for sharing !!
Alberta is like the most difficult place to do passive solar. I think that starting at Chatham Ontario zone 6A or even goderich zone 6B would make it easier. You might not even need the blanket just the double plastic layer. I think and acre of land could be found in Chatham or in Goderich.
No doubt.... Such a fantastic... Build and explaining everything very well... Thanks and appreciate you and your wife for both of your hard work and execution to come to this tech greenhouse in reality.
Bless you you are doing a wonderful job thank you for sharing your greenhouse it stimulates others to join you in this bouquet of vegetables thank you again
Thank you for posting this! I am just starting out in farming and have some experience in passive solar and was designing a similar set up to start building on my land east of Edmonton, I'm impressed with his setup.
Then Jeff, you should look at the greenhouse I am building right now in my backyard. See why I dig 4 inch deep and create the massive thermal storage with a pond liner, rocks and water.
@@AubreyZhang once I het the money together to start on the big greenhouse ill likely do a 4x 1200L bins buried in sand and Insulate heat battery underneath. Thermal mass heating is definitely a huge add on to a green house of any size. :)
@@jeffp366 You did not get my point, Jeff, check my channel about the using soap liquid bubbles to take care of all the problems associated with traditional single layer greenhouses.
FYI Proper latitude/glaze angle has been shown to be a bogus concept. In other words, the same results are achieved ,as long as you don't go too severe of an angle. This also helps in NOT having to go too vertical of a roof/glaze in Northern parts of the country, for example 60 degrees. Stick with about max 30-45 degrees, and you will get the same results.
Thanks for your comment. Do you have source material about this? I plan to start building a passive solar greenhouse in 2024 and this would be helpful info.
@@garthwunsch I feel sad that there is much much better design for greenhouse. It has been well developed by Richard Nelson since 1980's and he lived there in Quebec, still living there today and now. No body talks about his greenhouse, not even by those who call themselves expert! That is sad and shameful!!!
@@LowHangingFruitForest That's why there are windows at the top and you can roll up the bottom. Besides, the greenhouse is a tool, not a moonscape biosphere. You plant outside when the weather permits.
Control of Aphids completely organically You need to start a worm farm and make your own worm castings. Once you have a supply of castings, make worm tea and water the plants that are infected with a dilute solution of worm tea. Worm tea contains chitinase, which is an enzyme that breaks down the chitin which is the principle material of the exo-skeleton of many bug pests. I did this unknowingly the first time to some infected pepper plants and the plants had no aphids and new healthy leaves in 2-3 weeks. Plus the worm tee is great for helping plants utilize minerals in the soil that the gut biology of the worm helps the plants process.
Please do another one with Don Jianyi going into more detail, as one hour was too short. :) Questions unanswered were how did you move clay to berm, how did he construct the berm, will he create a company to sell his prototype to North American market, will he rigorously document on UA-cam his 2nd version of the PH Greenhouse (please do so!). My grandparents were dairy farmers in South Dakota long ago and remember the soil being 3-4 meters deep and black thanks to the buffalo. Now nothing is left except chemical fertilizer. We need to rethink our exploitive practices and return to regenerative ones.
use an excavator and raise it to dump into the berm, simple. He just finished a second greenhouse and 5 greenhouses without the north wall in this year.
Good video thanks for the information. I must say I love what is going on in Alberta with all the passive design , solar, geothermal and just basically energy independence. Wish I liked the snow.
You can also use it in warmer climates to get plants which need higher temperatures, or to reduce your heating bill in the winter, and with underground air pipes (2 meters or 2 yards below the ground) for geothermal heating, you can also lower the cooling bill in the summer.
I've been researching indoor growing, aquaculture and related subjects for 14 years. Right now, Im staying in a building with a perfect spot for a rooftop, passive solar greenhouse. It has a north and west wall. I'd like to build one, but for as cheap as possible.
Wow! I was really impressed by the acres and acres of greenhouses in northern China. See them at 1:18. The Chinese really know what they are doing and we need to learn from them, rather than stumbling around attempting to reinvent the wheel.
I think the roll down curtain is fantastic. Can you tell me about the thermal curtain you are using? What kind of material and where did you get it from? thank you
Question: In your opinion, is it feasible to use back wall as composting reservoir? During spring and summer filing it up with dry biomass and activating it at later date by simply adding water?
Thank you for sharing this. Very informative. I was wondering about pollination. Is the green house open during the summer to let the pollinators in? (bees and so forth). Thank you.
You may want to add some geothermal piping below the frost line in the ground. This could offset both the cold and the heat. Down by my in NJ. USA. Ground temperature stays at around 13-15 C all year long
The design is simple and logical. I question why it is not more common or begun long time ago. The greenhouse presented here is large and of commercial use. I think we can modify the design for a smaller model according to local weather condition and needs. As such, the building materials may be substituted by locally sourced products. Just let your imagination go wild.
@@dongjianyi2492, Xin Nian Hao! This is really encouraging. China is so advanced at this. I never knew. How can we buy kits from China? Can you provide a source to buy from? And then we need a manufacturing system to start here in the US. Thanks! P.S. Tell people that your name is in two distinct syllables. If they put a hesitation between Jian and Yi, they would pronounce it more correctly. P.P.S. I taught English in Baoding at Hebei Agricultural University in 1986.
Normal water consumption is 400 m^3 without artificial irrigation. If some kind of watering system is implemented, 250 m^3 annual consumption is the norm.
Isn't the humidity something you can control with the back wall? If you would use clay instead of steel, the clay could take and give humidity. For pest control, you can buy special bugs. I wonder how this would improve if you would additionally switch to hydroponic or even Aquaponic. I bet I would improve even more.
Overall, it seems to me that this would be a very suitable situation for more living components! It would be wonderful to see less standard monoculture style. Great design for the greenhouse on its own however!
This is so interesting! What woukd the critical mass be dimension-wise where this can still work? I have a generous back yard but won’t be able to accommodate a greenhouse this size.
Thanks for this! How can I order a particular design from China? It will need to be suitable for 59.3 Latitude/7.97 Long/560 m above sea with good High Snow Loadings minimum 300kg/1 sq m.
THE tomato vines that you lowered, if covered with soil and moisted will give a lot of new roots and nutrition for your plant. Not easy to do it with plastic mulch.
May I ask if there is data regarding annual energy consumption of the greenhouse? I'm currently doing a project and looking at incorporating a similar greenhouse to the design.
Clay forms a stable composite mass, it has structural strength, especially when dry, supporting the walls. Sand does not have any structural integrity and would constantly challenge your wall. Bit of a no no. Having said that if you did a 1/6 cement mix it would have enough strength not to challenge the berm integrity.
I really apreciate your efforts and then putting it out there! What’s specially great is that I also live in Alberta! So often the things I watch are not directly comparable at all! Where in Alberta are you located? I’d love to come compliment you in person some time.? Also the questionevery one wants to ask but are to polite is roughly speaking what was the material cost? You mentioned that it took a season? To construct for two people that haven’t done it before? I like the idea of doing one but I have less desire to be a gardener! I just like designing and engineering ideas and making/building things trouble shooting along the way. This all seems very interesting to me! I have several ideas.. Thanks again
Not an expert but; Probably. You'd need to see if your output was worth the extra cost. And you may need to plan light exclusion if growing other plants, as it might affect their light/dark periods.
I don't think it would be viable. The lights would have to be so close to each plant, you would need thousands of them. It would cost a fortune for little benefit.
Great info. Thx. for the video. Could you answer the following please? * Is this brick wall on the north side inside the green house or outside? * What type of insulated blanket is this? Where do you get it? * What is the approximate cost that i looking at for one of these? * Why did you cover those Green Reddish, Dill plants in Plastics inside the Green house? * Has any Canadian designed their green houses using this design with Canadian matriels? * Do you have any contact details to get more info.?
I wonder how the. polythene is fix ed to the frame; if there is no second polythene cover, and if it rains. the black cover will get heavy, and weigh down on the polythene, which could make the polyethylene sag
I understand the design depends mainly upon thermal mass to store the heat and radiate it in the cooler part of the day. Your green house works on 10,000 sq feet. Do you have math available to calculate the smallest effective size for this design?
Good time of day! Tell me, please, where can we learn from the experience of permaculture in a greenhouse? I want to move with my family for a year of work in such a farm to gain experience. Naturally, with a payment (salary), so that there is something to live on.
Hi, my name is Daniel Bergman and I live in southern Sweden. our winters are usually at minus 2-3 degrees Celsius, a few days/weeks per year the temperature is often down to -10 and the most extreme it can be -20 some night. I've watched your movies and am very inspired. I myself have planned to build a Walipini which I plan to build with a trusting plastic roof of 6 x 24 meters, I see an advantage if I can combine it with a protection over the plastic at night. I have some questions: 1. can you order measurements of insulation cloth specially? 2. Do you have a Chinese website that manufactures this? 3. how much does such a cloth cost? 4. you have two roofs. do you have to have it? and if you only have one, what do you do with the snow. does the cloth not break when it forces itself out over the plastic with snow on it? then I want to end by thanking you for your inspiring films! Sincerely Daniel Bergman
gabion walls are labour intensive as I understand. Jianyi used sheet metal and some sort of metal 'piping,' as I understand it, to contain the clay. I think that is pretty efficient already.
@@ScottYun Yes, Jianyi would've used his tractor to fill the back wall. As I understand it gabion walls are made of cages so where does the wall thickness come from?
Hi, Thank you for sharing! Very informative. I like your model and planning to build a smaller passive g/h in my back garden as a hobby in the UK. Our minimum temperature during the coldest months can be - 7 degrees. I’ve got few qs: 1. What kind of thickness of back wall should be for our climate? 2. Do I need to insulate 2 side walls? Many thanks!
The thickness for the north wall shall be at least 1m wide, better with 1.5 m wide clay wall. Do not insulate the wall inside the house, it absorbs the heat from the greenhouse during the day and releases the heat back into the house at the night.
The sheer lack of winter sunshine in northern Europe as a whole is the #1 limiting factor for any greenhouse design that wishes to grow warm season crops. Calgary has roughly 2.5x the sunshine hours that London has in December. Best of luck with your project, and let us know how it goes!
wow- sounds good but sadly I can't speak Chinese so I am not sure how I would order the bits and pieces he talks about - especially the amazing blankets which of course I would love to access. Maybe Jianyi can become an importer!
really interesting and hopefully will be used by more. I don't think thought that this is what is called a "passive" technology. In passive houses, there is no heat loss, because it's air tight and special windows, doors are used. This greenhouse does have a heat loss and would need heating to be able to grow veggies year around.
He works with his wife without any other helpers. Now he has two greenhouses with a north wall and 5 greenhouses without a north wall. Maybe he will have some helpers. This is my guess.
Interesting. You're already doing a better job of addressing sustainable solutions than the government of Canada...
Governments don't provide solutions
Anything the government gives you was first stolen, then leveraged with the central banks creating generational debt. Innovation stems from individuals having property and a little capital to play and try things.
@Dane Alberto your right. Nobody cares!
"Solutions" for what?
Do people really still think man made climate change is real?
Is there a quantitative snow load that this is designed for for instance 25 psf? Standard dutch houses are only 18psf and rely on snow melt systems even when there is 1m plus snow depth.
I just can’t get enough of this video. I want more. The great thing about this model is that it is one specific set of solutions. It’s a system, the whole thing.

Is the language barrier a problem when working with chinese distributors. What company in China has this speaker worked with and go over prices. Then discuss construction details and overall costs. This speaker should then offer consultation services for profit to help others get setup.
I think this is a gem. There are thousands of greenhouse solutions but not a lot of complete, comprehensive, fully tested and matured systems. Great Work!

Yes. I think it should be pretty easy to keep the temperature well above freezing in such a greenhouse in Germany.
And also citrus plants can deal with degrees minus 0.
@@kuhrqr Might try to grow one in my greenhouse
@@dongjianyi2492, Xin Nian Hao! This is really encouraging. China is so advanced at this. I never knew. How can we buy kits from China? Can you provide a source to buy from? And then we need a manufacturing system to start here in the US. Thanks!
P.S. Tell people that your name is in two distinct syllables. If they put a hesitation between Jian and Yi, they would pronounce it more correctly.
P.P.S. I taught English in Baoding at Hebei Agricultural University in 1986.
@@boa9535 haha, we never think about it. Just don't want people to think we have middle names
do you reuse any of the drip line and plastic mulch ? You must have one long handle on your snow rake!!!! Is the clay packed in your wall ?Tks
I reuse the drip tapes. The clay was not packed. But it is better be.
Move south in the winter?
DO YOU HAVE A BUDGET FOR 1 PIECE AND WHAT IS THE COST OF ADDITIONAL UNITS. VERY GRATEFUL THAT YOU WOULD SHARE SUCH TECHNOLPGY.
The cost for all the parts and material is about $100k CAD.
@@dongjianyi2492 Thanks.
How many square meters of growing space?
@@heraldchung4420 About 8000sqft
Very interesting thank you
Did he dig down and insulate the ground? Fabulous greenhouse.
Normal water consumption is 400 m^3 without artificial irrigation. If some kind of watering system is implemented, 250 m^3 annual consumption is the norm.
Isn't the humidity something you can control with the back wall? If you would use clay instead of steel, the clay could take and give humidity.
For pest control, you can buy special bugs.
I wonder how this would improve if you would additionally switch to hydroponic or even Aquaponic. I bet I would improve even more.
Overall, it seems to me that this would be a very suitable situation for more living components! It would be wonderful to see less standard monoculture style.
Great design for the greenhouse on its own however!
Good idea!
This is so interesting! What woukd the critical mass be dimension-wise where this can still work? I have a generous back yard but won’t be able to accommodate a greenhouse this size.
Do you have a CAD design of this greenhouse that we can buy?
Check out the guy that grows oranges in Nebraska.
Shop everything from China.

Thanks for this! How can I order a particular design from China? It will need to be suitable for 59.3 Latitude/7.97 Long/560 m above sea with good High Snow Loadings minimum 300kg/1 sq m.
is there a design that can be use in desert hot climate ???
THE tomato vines that you lowered, if covered with soil and moisted will give a lot of new roots and nutrition for your plant. Not easy to do it with plastic mulch.
Where do you get those blankets from? you said you found ones that warm better and cheeper? Thanks...
Shipping from China
China is very developed with passive greenhouses, you can order everything from China and it's not expensive.
De akkor mit tegyünk, ha állandóan felhő takarja a Napot?
Amazing greenhouse
Look into the "Back to Eden gardening method" adding their system as well as permaculture would really up your production and lower your labor.
what is the cost of labour in terms of manhours and rates
May I ask if there is data regarding annual energy consumption of the greenhouse? I'm currently doing a project and looking at incorporating a similar greenhouse to the design.
Would it be possible to fill the back wall with sand rather than clay ?
Clay forms a stable composite mass, it has structural strength, especially when dry, supporting the walls. Sand does not have any structural integrity and would constantly challenge your wall. Bit of a no no. Having said that if you did a 1/6 cement mix it would have enough strength not to challenge the berm integrity.
A lot of good ideas here
I really apreciate your efforts and then putting it out there! What’s specially great is that I also live in Alberta! So often the things I watch are not directly comparable at all! Where in Alberta are you located? I’d love to come compliment you in person some time.? Also the questionevery one wants to ask but are to polite is roughly speaking what was the material cost? You mentioned that it took a season? To construct for two people that haven’t done it before? I like the idea of doing one but I have less desire to be a gardener! I just like designing and engineering ideas and making/building things trouble shooting along the way. This all seems very interesting to me! I have several ideas.. Thanks again
Ah I see in the notes it says olds!im not too far in rosebud!
It took my wife and myself 1 year to finish building it. But we did not use full time. The cost was about $100kCAD
@@Eliukcory Feel free to come and check it out
Mr. Dong is in Calgary. He has two youtube channels.
Is this design applicable to areas with hot summers - up to 45C and moderate Winters (worst case -10C).
That's what most part of north China is like. They don't grow in July and August. But they grow in the whole winter.
Thank you!
This is amazing! Where in China are all these greenhouse communities located? I want to find them on google earth!
Awesome seminar, btw!
Thanks for the feedback! We're excited with how much traction this webinar has gained
If one were to add LED lights couldn't you extend the tomatoes for the whole season?
Not an expert but;
Probably. You'd need to see if your output was worth the extra cost. And you may need to plan light exclusion if growing other plants, as it might affect their light/dark periods.
I don't think it would be viable. The lights would have to be so close to each plant, you would need thousands of them. It would cost a fortune for little benefit.
Maybe only 1 or two months is not good for tomato growing.
Do you guys sell the architect plans if so I would like to buy ASAP but I need them in english.
Great info. Thx. for the video. Could you answer the following please?
* Is this brick wall on the north side inside the green house or outside?
* What type of insulated blanket is this? Where do you get it?
* What is the approximate cost that i looking at for one of these?
* Why did you cover those Green Reddish, Dill plants in Plastics inside the Green house?
* Has any Canadian designed their green houses using this design with Canadian matriels?
* Do you have any contact details to get more info.?
I wonder how the. polythene is fix
ed to the frame; if there is no second polythene cover, and if it rains. the black cover will get heavy, and weigh down on the polythene, which could make the polyethylene sag
Shhhh, common sense is on austerity right now don't be thinking to objectively 😊
I understand the design depends mainly upon thermal mass to store the heat and radiate it in the cooler part of the day. Your green house works on 10,000 sq feet. Do you have math available to calculate the smallest effective size for this design?
What I know is the width (span) of the greenhouse: 10-15 m is good. The length has to be at least a few times that length.
at 5:14 is that Celsius or Fahrenheit?
Good time of day! Tell me, please, where can we learn from the experience of permaculture in a greenhouse? I want to move with my family for a year of work in such a farm to gain experience. Naturally, with a payment (salary), so that there is something to live on.
Go to china, Shangdong province.
To live with Mr Dong for a few months. He has volunteers now from nearby to learn the passive greenhouse farming.
@@CN_SFY_General Thanks! Where is it located? Me and my family are from Russia.
@@sokkomp He's in Calgary, Canada. You may choose to go to China, in the north region, everywhere.
@@CN_SFY_General Can you be more specific, how can I find his?
Winter isn't a problem to be solved.
Hi, my name is Daniel Bergman and I live in southern Sweden. our winters are usually at minus 2-3 degrees Celsius, a few days/weeks per year the temperature is often down to -10 and the most extreme it can be -20 some night. I've watched your movies and am very inspired. I myself have planned to build a Walipini which I plan to build with a trusting plastic roof of 6 x 24 meters, I see an advantage if I can combine it with a protection over the plastic at night. I have some questions:
1. can you order measurements of insulation cloth specially?
2. Do you have a Chinese website that manufactures this?
3. how much does such a cloth cost?
4. you have two roofs. do you have to have it? and if you only have one, what do you do with the snow. does the cloth not break when it forces itself out over the plastic with snow on it?
then I want to end by thanking you for your inspiring films!
Sincerely
Daniel Bergman
Great video.
You could add a compost pile and have additional heating
Six inch pipe eight foot underground could be used to cool the greenhouse in the summer and heat it in the winter.
Where can we contact you to find a green house like yours?
There's gabion cages with geo-fabric. So you can build the back wall with on-site dirt.
gabion walls are labour intensive as I understand. Jianyi used sheet metal and some sort of metal 'piping,' as I understand it, to contain the clay. I think that is pretty efficient already.
@@bounjamin Backhoe rental makes quick work of the labor. It also has significant termal mass compared to the thin walls shown in the video.
@@ScottYun Yes, Jianyi would've used his tractor to fill the back wall. As I understand it gabion walls are made of cages so where does the wall thickness come from?
How big is your greenhouse ? And how much did it cost to buy and import from China ?
8000 square feet
This is amazing. Very impressive. 👍
Do it work in 59 latitute?
Hi, Thank you for sharing! Very informative. I like your model and planning to build a smaller passive g/h in my back garden as a hobby in the UK. Our minimum temperature during the coldest months can be - 7 degrees. I’ve got few qs:
1. What kind of thickness of back wall should be for our climate?
2. Do I need to insulate 2 side walls?
Many thanks!
The thickness for the north wall shall be at least 1m wide, better with 1.5 m wide clay wall. Do not insulate the wall inside the house, it absorbs the heat from the greenhouse during the day and releases the heat back into the house at the night.
The sheer lack of winter sunshine in northern Europe as a whole is the #1 limiting factor for any greenhouse design that wishes to grow warm season crops. Calgary has roughly 2.5x the sunshine hours that London has in December. Best of luck with your project, and let us know how it goes!
wow- sounds good but sadly I can't speak Chinese so I am not sure how I would order the bits and pieces he talks about - especially the amazing blankets which of course I would love to access. Maybe Jianyi can become an importer!
I think that you could ask Mr. Dong to help you. If more people ask, he can organize group buying and everyone will get a better deal.
how much is one 'truss'???
really interesting and hopefully will be used by more. I don't think thought that this is what is called a "passive" technology. In passive houses, there is no heat loss, because it's air tight and special windows, doors are used. This greenhouse does have a heat loss and would need heating to be able to grow veggies year around.
Where can I order one in canada?
Will this be a company building it or DIY ?
Very nice indeed greenhouse Champion! How many ppl work with you for years round? j/w. Thank you.
He works with his wife without any other helpers. Now he has two greenhouses with a north wall and 5 greenhouses without a north wall. Maybe he will have some helpers. This is my guess.
Citrus in the Snow from Nabraska USA has greenhouse kit simular to this.
You could set the compost pile up just to heat your back burner
Where can I buy the greenhouse frames from?
where can i buy the insulated blankets here in alberta?
Everything is from China for the greenhouse, even his excavator is from China. It's cheaper.
I love UA-cam algorithm!!!
