I wish the world could get along everyone has something to teach someone but stigmas or government propaganda push everyone to trust noone its sad. Make peace not war. This dude is great
Yes, it is an amazing design with lots of room to grow. With the shape of those greenhouses, a roof vent electric turbine would generate nice power in windy Alberta. There is also a new semi-transparent film solar panel that can be placed over greenhouses.
I've seen Jianyi's video a couple of years ago on his Chinese greenhouse. It completely changed what I had planned to build. I'm glad I saw it. Great job. To those who want to save some money on thermal blankets, I'm using the orange thermal blankets that are used for concrete. Nice and light too.
My uncle is building an almost passive greenhouse. You can use the ground under the greenhouse as a thermal battery. If you go down a few feet, the temperature is a perfect growing temperature year round. All you need is a fan to move that air around to keep the greenhouse warm in the winter and cool in the summer.
The beauty of Mr Jianyi system is how well it works without adding expensive supplemental heat. The key points that make his system work so well is the AMOUNT of winter sun he receives in his area and his ability to absorb the excess heat into the back wall and ground. The effective conservation of that absorbed heat through his roll down insulation is amazing and yet so simple. I would be interested in hearing how well the scavenging of the heat from his generator is going along with the bitcoin mining end of things. We farm in Alaska, mostly tomatoes, and when I first read about his incredible operation a few years back I researched every aspect of doing something like this here at our place. Unfortunately, our reality is that we just don't have enough sun and have way to much cloud cover during our long winters to make this work for us this far north. But..... this is future for year round veggie production in cold climates with good sunny winter days.
There is a family that built a green house in Mongolia that is relying on an underground heating battery. If they can extend the season anyone can. In areas where the sun is the limit it isn’t very expensive to ad extra light during the dark period. The place where it will be a really challenge is where you don’t have any sun and at the same time it is very cold.
I've been building passive solar homes with attached greenhouses since 1981. I will not build a personal home any other way for the simple fact that it works for the life of the structure at no cost.
I built several a decade ago in Manitoba . though mine is a bit different shape to take advantage of snow loading on the glazing to act as added insulating blanket during the winter ( google- krywenko greenhouse) , but the same principle. in my climate of hardiness zone of 2b @ lat of +51 . they stay above zero usually until mid dec. then they cool off fairly quickly as it get closer to the winter solstice. and usually for 2 weeks the green house will stay below -5C in the beginning weeks of January until the sun intensity increases enough to start warming the air faster then it can escape through the glazing . then by mid February early March it can remain above zero 24/7 . but by the spring equinox you are good to go. I use my Chinese style green house to grow peaches and nectarines for myself and my family in Manitoba . and I adjusted so does not retain to much heat. as i have built ones that mimic hardiness zone +9. but I had issues of my fruit trees blossoming in mid January to early February . but due to the lack of light they would just sit in bloom until mid march. so i adjust down so now they mimic hardiness zone 6. and the trees bloom in March/April.. which is closer to what they would do in Nature . so i get better fruit production and really when the sun intensity support growth
Fascinating - thanks for sharing! I tried to search Krywenko GH on google and found an old forum posting of yours on Open Energy Monitor - super interesting stuff! Hoping to build a passive solar GH of my own one day!@@skrywenko6596
Saw these style of greenhouse on my first trip to China around 1995. They used rolled grass layer to roll down during night to prevent heat loss. This design is notched up and less labor intensive but the idea is still brilliant. Liked it back then and hope it gains popularity as it helps reducing the need to extensive use of burning oil or gas to heat the building.
I think I like the Arktopia design with the overhang that protects half the greenhouse from over heating in the summer, but captures more of the light in winter months.
Great video, I would like to see a construction deep dive to get into details of the back wall materials, wall construction and blanket furler/material
I've been out to visit Jianyi... love his set up! Bought some of his seedlings & they worked out great in my garden. Nice fella & gave my friend and I some awesome advice! And also.. it was -28 celsius outside when we went & when we stepped inside the greenhouse we hand to un-layer quite quickly!
Excellent video. Would greatly appreciate more details on this cold-climate greenhouse. Please create second video to explain: 1. Is the 2nd poly (inner) layer only erected in winter season, then removed in summer? 2. That layer appears to be open at the last top meter, is that to give access to operate the insulation blanket? 3. Does closing the insulated blanket at night create significant frost buildup on the interior face of the outer poly layer? (reduced temp of cavity between poly layers would drop space to below dewpoint) 4. What material was selected for insulation blanket? 5. Details of snow vibrators? 6. It appears that a shading canopy was up, is this kept up all winter?
Great video; thanks for sharing! I watched your older videos when you highlighted all the different cold weather growers & am intrigued by the amount of work he & his wife did to build the huge wall by hand! I’m looking forward to seeing more. 🤗
This is perfect all I can add is divide all to six sections and u’ll be able to plant and harvest EVERY MONTH. It’s al year round , use it! Everyday fresh !😊
I've seen him before on RUclips, I believe he has a very small channel subscriber wise but he's had one of the videos showing the passive solar greenhouse go viral. Definitely a very cheap way to put up a lot of infrastructure. A farmer could do well on a small plot with a growing area like that. I wonder if they are still 100k after the last few years of hyperinflation.
It is already done in different parts of the world. It's a modified earth ship designed by Mike Reynolds. Another alternative is a super insulated home with a deep mass sand bed. In Sweden a company called Polar Nights Energy is utilizing a very large, well insulated area that contains sand and pipes. The sand is heated by wind or solar in the summer to 600 degrees C. That heat can be stored for months. Air is blown thru the pipes when energy is needed and that superheated air goes thru a heat exchanger to heat water to steam pressure which runs a turbine to produce electricity. The waste heat is used to heat buildings. There is currently a system in place that provides heat and power for about 350,000 people. On a smaller scale in cold climates pumping heat into an insulated foundation under a home has great potential.
Say what you like about the Chinese and their repressive government. They are geniuses in the greenhouse technology field, and we have a LOT to learn from them. Jianyi is doing the impossible (to us) in a very challenging climate and I tip my hat to him. Very, very ambitious!
This is a very good solution for a very specific situation. You need a lot of sunny days otherwise you won't have heat. And you need a lot of space because with this design you can't build greenhouses next to each other. Also because you don't burn a fuel for heat, you don't have CO2 to inject into the greenhouse. Meaning plants grow slower and you produce less per square meter. So this solution is perfect in certain locations for smaller scale farming, but it won't work on a grand scale for mass food production.
Nice job. They've been doing it in Wyoming for decades this is not a new technology but it looks like he's perfected it. This would be good for the future if more people applied to science
No, the Wyoming greenhouses are not like this at all. I've seen them, and they are well thought out but not in the same league. The Northern Chinese greenhouses are in a class all their own, and this IS a new technology perfected there over many decades. Here on the lower mainland of British Columbia we have acres and acres of conventional commercial greenhouses heated by natural gas, and the owners would like the taxpayers to pay their gas bills!
i am so happy to see this video! I live SE of Calgary and have heard about these greenhouses, and always wished i could hear more about them. I am wanting to market garden on my property, so thank you for doing this interview!
I would love to know more about the availability of the structure, what supplemental heating and light systems are used, and how to build the structure. I run a 4 acre vegetable farm in Montana, USA. With about a half acre of high tunnels and greenhouses. The low night temperatures in the winter (regularly below 0 degrees and as low as -40 degrees) makes it nearly impossible to grow anything in the winter without a ridiculous fuel bill. I Enjoyed the video and would love to see more!
This is a form of geothermal but is probably better named a climate battery. He's pumping hot air during the day into his clay wall to store heat that then radiates out at night. In some ways it's way better than conventional geothermal because you don't have to drill super deep or trench outwards hundreds of feet like Citrus in the Snow guy. Plus, in this location the soil freezes very deeply so geothermal trenches would be more expensive than warmer zones.
In our northern climate, the minimum upper depth of our septic and water systems is 10 ft. We have approximately 12,000 sq ft of high tunnels. The install and operating costs to build a functioning geothermal system does not pencil out for us at all. @@cupbowlspoonforkknif i
We raise cows and other life stock and we have experimented with several types of compost heat over the years. We garden in over 12,000 ft of high tunnels. Two issues with this, it is VERY labor intensive to make and maintain a proper compost pile and it is impossible to make compost outside under the snow and then transfer heat to the growing beds. It very difficult and hard to generate a reliable system that wont fail you during the really cold winter months. AKA, frozen plants. Compost releases a lot of moisture and if you try to do that inside of the facility you need to vent out the moisture and there goes the direct heat gains. Spending five bucks to save a buck is a dead end business practice for small farms.
Thank you for sharing the knowledge I always do enjoy learning something useful. It seems to work very similar to geothermal greenhouses. Although geothermal greenhouses would be a bit more expensive to build, particularly on the size of those huge greenhouses. I live in Alberta too up in Edmonton so not too far. Since Covid I’ve been making a lot of my own food buying products directly from farmers, such as beef, pork chicken, butchering it myself, and even making my own curd meats. I’ve also started to learn how to can and I’ve been making my own pasta sauce from scratch, along with salsa and even ketchup. Might have to visit your farm someday and pick up a dozen boxes or so of tomatoes be interesting to see how those sweet tomatoes work in salsa and pasta sauce.
I have started to design a small 7m x 10m greenhouse like this based on what I have found on internet. Not built yet. Want to learn more. This was great to see!
what is the specific material of the insulating blanket. I'd like to just add that rolling blanket feature to a future build. Can you share where you purchased this greenhouse from? I know these chinese style had originally the blankets on the outside, so its interesting to see how they have modified it to protect the blanket. Kinda looks wonky though when rolled up, not sure if thats a durability problem down the road though.
He imports them himself. The reason the blankets are inside is because freezing rain or melting cycles can freeze a blanket to the outside causing you to lose your entire crop.
@@cupbowlspoonforkknif There was an earlier version of the Chinese style greenhouse built in Elie Manitoba that was doing experimentation for the University of Manitoba. The grower had exactly that happen when the exterior insulating cover froze over in I believe January and he lost the crop.
In Germany we harvest with Cherrytypes like Supersweet over 35 kg compared to here mentioned 15kg in the same Periode. To have so much space between compartments would not be possible cause €/m2 is too high. Also benefit of the stored energy in the backwall in winter is very limited. In the 80th they have done test. A square with up to 8 m high walls is more efficient and better to control. We have a 3 layered energy saving system with screens what is more flexible. First a shading screen what helps in summer (above 27 Degrees Celcius Tomatoes respirat more than they gain from photosynthesis) second is a energysaving screen what can led some light through but no direct radiation out. Third is a strong covering what is used during the night in combination with the other two screens. All three are controlled by computer depending on radiation from 0-100% and in future by AI. Heat is produced by combined heat and electricity generators what have efficiency up to 96%. Electricity is needed for LED cause light (not temperature) is often the limiting factor in winter. The CO2 is used for fertilizer cause that drops quite fast in winter when all ventilations are closed.
Would be very interesting to see a video of your system as it sounds amazing. I hope to build more of a Walipini once I 'retire' from day job and always keen to see what ideas are being used even the ones I can't afford!
Great way to grow tomatoes in cold climate! How about light in the winter? Isn't it pretty dark from November to March? What kind of lighting do you have for those dark periods? Thinking out loudly - in Finland there is a quite new interesting invention about storing heat in sand batteries to warm up houses. Maybe something similar could be useful to heat your greenhouses, too?
that's what the North wall does - low angle sun in the winter heats up the back wall. In the video he talks about the tons of clay, with an insulating blanket between the outer wall and the ground.
@@GlueTubber Hm, that's not what I meant. At my location at latitude 58 N, there is 10-40 W/m2 during typically cloudy days from beginning of November to beginning of March. And that is at least an order of magnitude less than vegetables need for any useful production. BTW, if I recall correctly, that wall was mostly black.
@@GlueTubber Sorry, I answered incorrectly. That wall definitely helps, but it heats up just moderately. That so called sand battery from Polar Night Energy is heated from multiple hundreds up to 1000 degrees C. It has really huge thermal capacity.
@@tonisee2 I'm struggling to find hard numbers of what kind of solar irradiance he sees in South Central Alberta, but as the statistically sunniest place in Canada (or at least adjacent to it), and at ~52N I expect some pretty significant heat gain. That said, we do get an awful lot of darkness this time of year, and judging by his comments about diesel generators I imagine he must have some sort of lighting system in place.
Yes, darker in winter here but not like the Nordic countries. Day length right now is 8 hours. It's also very sunny here, almost the sunniest place in Canada. I don't know if he uses lights, I didn't see any in the video.
We used triple layer polycarbonate glazing, metal stud frame, 55 gal drums for thermal mass, louvers, fans & shade cloth. One small electrical heater kept the space from freezing in Medford, Oregon with temps down to 20degF
All the improvement from the original design such as the inner insulating layer and using large thermal mass with a dark surface to hold and store heat is dramatically in the right direction. The only differences are latitude and winter time lows. As you move further away from the equator in january etc. the hours of sunshine drop dramatically and in Olds Alberta where these greenhouses are located they can get -40 deg. F temperatures so your heat loss delta between 40-70 deg. F inside and outside -20 to -40 degrees F shows why he had to add a relatively small heat suppliment as vs 2 years ago when he ran these greenhouses with no heat input. I wonder if he puts some heat into the soil. Plants with warm soil can endure colder air temperatures and still thrive. Probably due to the biology staying active.
This ia a wonderful, successful project! I would love to hear any information that he could provide regarding any challenges that he is encountering with pest control. Is he using any pesticides or fungicides? Also, is he able to utilize the same soil year after year and simply add compost and other soil amendments? Or does he need to replace the soil periodically?
Fascinating, thanks for sharing! The huge amount of plastic is a bit daunting, but I would guess that all things considered, it is a positive choice. I must add that the repeated music-loop in the background is very annoying.

Amazing greenhouse. Such a thoughtful design and a very humble owner.
I have a very small experimental greenhouse. It’s been awesome growing through the winter. Everything is so crisp and sweet. Nice video.
Yes, it is an amazing design with lots of room to grow. With the shape of those greenhouses, a roof vent electric turbine would generate nice power in windy Alberta. There is also a new semi-transparent film solar panel that can be placed over greenhouses.
He is not that humble.
Check his Chinese language channel and see his boasting and arrogance about Chinese made stuff and attitudes.
I've seen Jianyi's video a couple of years ago on his Chinese greenhouse. It completely changed what I had planned to build. I'm glad I saw it. Great job. To those who want to save some money on thermal blankets, I'm using the orange thermal blankets that are used for concrete. Nice and light too.

I was actually thinking if this was a viable option for Alaska?
@@hamadilawson7634 i'm in scotland and doubt it is viable here. too little light winter.
Wind is probably the best suited energy for Scotland, trap the heat, self contained environment.
There is a family that built a green house in Mongolia that is relying on an underground heating battery.
If they can extend the season anyone can.
In areas where the sun is the limit it isn’t very expensive to ad extra light during the dark period.
The place where it will be a really challenge is where you don’t have any sun and at the same time it is very cold.
It's perfect for cold sunny places like Dongbei and Mongolia, and North America

I've been building passive solar homes with attached greenhouses since 1981. I will not build a personal home any other way for the simple fact that it works for the life of the structure at no cost.
Where are you building

Its a kit from China so the plans would be somewhat irrelevant @@losclaveles
It’s built regularly in Spain, costs much more to build in Europe. The wind destroy them often and the profits are from economy of scale.
Great idea! Being done in China for decades, he said. We could apply this principle to housing and save in heating bills.

Note that in the southern hemisphere you'd want the vertical wall facing south and the transparent facing northward toward the sun.
I want one. The heat blanket on the inside is something i havent seen yet very nice.

This is a very good solution for a very specific situation. You need a lot of sunny days otherwise you won't have heat. And you need a lot of space because with this design you can't build greenhouses next to each other. Also because you don't burn a fuel for heat, you don't have CO2 to inject into the greenhouse. Meaning plants grow slower and you produce less per square meter. So this solution is perfect in certain locations for smaller scale farming, but it won't work on a grand scale for mass food production.

Two other types of heating I would like to see perfected and commercialized to add to greenhouses like this would be geothermal air and compost heat.

Thank you for sharing the knowledge I always do enjoy learning something useful. It seems to work very similar to geothermal greenhouses. Although geothermal greenhouses would be a bit more expensive to build, particularly on the size of those huge greenhouses. I live in Alberta too up in Edmonton so not too far. Since Covid I’ve been making a lot of my own food buying products directly from farmers, such as beef, pork chicken, butchering it myself, and even making my own curd meats. I’ve also started to learn how to can and I’ve been making my own pasta sauce from scratch, along with salsa and even ketchup. Might have to visit your farm someday and pick up a dozen boxes or so of tomatoes be interesting to see how those sweet tomatoes work in salsa and pasta sauce.
Great idea and technology
Amazing thank you
Very clever and thoughtful.
I have started to design a small 7m x 10m greenhouse like this based on what I have found on internet. Not built yet. Want to learn more. This was great to see!
what is the specific material of the insulating blanket. I'd like to just add that rolling blanket feature to a future build. Can you share where you purchased this greenhouse from? I know these chinese style had originally the blankets on the outside, so its interesting to see how they have modified it to protect the blanket. Kinda looks wonky though when rolled up, not sure if thats a durability problem down the road though.
He imports them himself. The reason the blankets are inside is because freezing rain or melting cycles can freeze a blanket to the outside causing you to lose your entire crop.
@@cupbowlspoonforkknif There was an earlier version of the Chinese style greenhouse built in Elie Manitoba that was doing experimentation for the University of Manitoba. The grower had exactly that happen when the exterior insulating cover froze over in I believe January and he lost the crop.
Excited to see this greenhouse tech! Want to make where I live in Vermont!
Great video!! 💪👍
Thanks so much! I learned so much
Really interesting style of greenhouse! I guess my little home made set up could receive a upgrade, lol.
In Germany we harvest with Cherrytypes like Supersweet over 35 kg compared to here mentioned 15kg in the same Periode. To have so much space between compartments would not be possible cause €/m2 is too high. Also benefit of the stored energy in the backwall in winter is very limited. In the 80th they have done test. A square with up to 8 m high walls is more efficient and better to control. We have a 3 layered energy saving system with screens what is more flexible. First a shading screen what helps in summer (above 27 Degrees Celcius Tomatoes respirat more than they gain from photosynthesis) second is a energysaving screen what can led some light through but no direct radiation out. Third is a strong covering what is used during the night in combination with the other two screens. All three are controlled by computer depending on radiation from 0-100% and in future by AI. Heat is produced by combined heat and electricity generators what have efficiency up to 96%. Electricity is needed for LED cause light (not temperature) is often the limiting factor in winter. The CO2 is used for fertilizer cause that drops quite fast in winter when all ventilations are closed.
Would be very interesting to see a video of your system as it sounds amazing. I hope to build more of a Walipini once I 'retire' from day job and always keen to see what ideas are being used even the ones I can't afford!
I am in Yorkshire England
Fascinating!
So Awesome!!!
Awesome!
Very cool. Thank you
I am interested in this for my home gardening. I would love to attach to the south side of my house for the benefits.
Great way to grow tomatoes in cold climate!
How about light in the winter? Isn't it pretty dark from November to March? What kind of lighting do you have for those dark periods?
Thinking out loudly - in Finland there is a quite new interesting invention about storing heat in sand batteries to warm up houses. Maybe something similar could be useful to heat your greenhouses, too?
that's what the North wall does - low angle sun in the winter heats up the back wall. In the video he talks about the tons of clay, with an insulating blanket between the outer wall and the ground.
@@GlueTubber Hm, that's not what I meant. At my location at latitude 58 N, there is 10-40 W/m2 during typically cloudy days from beginning of November to beginning of March. And that is at least an order of magnitude less than vegetables need for any useful production. BTW, if I recall correctly, that wall was mostly black.
@@GlueTubber Sorry, I answered incorrectly. That wall definitely helps, but it heats up just moderately. That so called sand battery from Polar Night Energy is heated from multiple hundreds up to 1000 degrees C. It has really huge thermal capacity.
@@tonisee2 I'm struggling to find hard numbers of what kind of solar irradiance he sees in South Central Alberta, but as the statistically sunniest place in Canada (or at least adjacent to it), and at ~52N I expect some pretty significant heat gain.
That said, we do get an awful lot of darkness this time of year, and judging by his comments about diesel generators I imagine he must have some sort of lighting system in place.
Yes, darker in winter here but not like the Nordic countries. Day length right now is 8 hours. It's also very sunny here, almost the sunniest place in Canada. I don't know if he uses lights, I didn't see any in the video.
Bravo !
Such a great idea ✅
We used triple layer polycarbonate glazing, metal stud frame, 55 gal drums for thermal mass, louvers, fans & shade cloth. One small electrical heater kept the space from freezing in Medford, Oregon with temps down to 20degF
All the improvement from the original design such as the inner insulating layer and using large thermal mass with a dark surface to hold and store heat is dramatically in the right direction. The only differences are latitude and winter time lows. As you move further away from the equator in january etc. the hours of sunshine drop dramatically and in Olds Alberta where these greenhouses are located they can get -40 deg. F temperatures so your heat loss delta between 40-70 deg. F inside and outside -20 to -40 degrees F shows why he had to add a relatively small heat suppliment as vs 2 years ago when he ran these greenhouses with no heat input. I wonder if he puts some heat into the soil. Plants with warm soil can endure colder air temperatures and still thrive. Probably due to the biology staying active.
This ia a wonderful, successful project!
I would love to hear any information that he could provide regarding any challenges that he is encountering with pest control. Is he using any pesticides or fungicides? Also, is he able to utilize the same soil year after year and simply add compost and other soil amendments? Or does he need to replace the soil periodically?
Color me impressed 😊 👍👍
Very nice, Thankyou!!!!!!!
Me: Has trouble assembling Ikea furniture.
Jianyi: Puts together 20,000 sq feet of greenhouses.
This is awesome
I couldn't help but think what if you built a house inside the greenhouse too?
Just build a passive solar house. The humidity and overheating in summer are not things you want or need to deal with.
It has been done, it was very interesting and they didn’t seem to have many problems. You may find it on iTunes or google. Phil.
Amazing
I love this! How does the system work for rolling/unrolling the insulated mat? I'd love more details!
Its on an electric drive. You just hit a button. He closes it before sunset when the greenhouse is about 70F- 20C. It could be automated by now.
Fascinating, thanks for sharing! The huge amount of plastic is a bit daunting, but I would guess that all things considered, it is a positive choice. I must add that the repeated music-loop in the background is very annoying.
