Hi everyone. Jianyi mentioned in one of his posts that he lives in Olds, Alberta. I live in Lethbridge, Alberta, 3 1/2 hours South of Jianyi. I contacted him to see if we could tour his greenhouse and he was VERY accommodating.. We saw it yesterday, Feb 16th, 2021.. It is amazing. After 2 solid weeks of daytime high temperatures between -20C and -35C the temperature inside his greenhouse was still 16 degrees ABOVE zero. NOTE that the past 2 weeks was a bit unusual for temperatures in our area. I know many think we live in igloos year round, but two weeks of subzero was definitely unusual. It's really a great way to build a greenhouse. Jianyi was very hospitable and suggested we should come back in the summer when his crops are in full bloom. I REALLY thank him for welcoming us and wish him well in the future.

I think geothermal would work pretty well to avoid the temperature dipping below 0°c. There’s a video titled Nebraska retiree uses Earths heat to grow oranges in snow, he explains how he has pipes under ground 8ft deep which out puts air temperature at 52°f or 11°c no matter the time of year and outside temperature, it could mean you could take the insulating layer off the green house more often even on cloudy days meaning it would grow the plants faster.

That's an excellent greenhouse. I've been looking to do something like this but on a much smaller scale. I've seen many people use PVC rain barrels painted black and filled with water to absorb heat from the sun. Water holds over 40 times the heat energy of concrete or stone. Also there's a lot of people using "passive Geothermal". Just drainage pipe under ground below the frostline with a fan. Takes a lot of heat out of the ground in winter, and put's heat into the ground in summer. Also takes excess moisture out of the air.

I think the stuff you're doing here is amazing -- but if you haven't already, you should check out what some of the folks are doing in Maine, Vermont, and Ontario (ex. Eliot Coleman + Connor Crickmore). They're doing similar stuff with even lower-tech greenhouses and really maximizing space utilization. I also grow year-round in my greenhouses, and with appropriate timing I earn a living wage all winter with unmodified double-layer-inflated greenhouses (Southern Ontario, Zone 5b). Tomatoes decline in profitability as the light decreases, whereas winter greens aren't affected nearly as much. Cutting the tomatoes out earlier could give you more time to establish profitable winter greens crops that would keep the revenue stream more consistent across the year. Amazing stuff you're doing!

A few drums, will make no difference in such a vast space especially compared to that wall. 3.3feet x 300 feet x 6 feet (probably in height) = that's 6000 cubic feet of clay painted black :) - about 200 of those cubic meter water tanks.

I think geothermal could be an economical option if done right when building the new greenhouses. If you rented a tractor-sized trencher you could trench about 5 feet down and lay pvc pipe down the middle length of each house, with smaller pipes T-d out every 25-50 feet or so. That way one blower at one end of the house could force air through the pipes to circulate air in the whole greenhouse. You wouldn't get as much warming as you would with a 40 foot deep pipe, but it should be enough to keep it above freezing. The slightly warmer temperatures might also help the vegetables grow faster, which could make the difference in whether or not it is economical for you. Just a thought.

Just like your were saying, there is just no way to cost effectively add supplemental heat to these high tunnels in this northern climate . This coming spring I need to rebuild one of our wind damaged tunnels and I was planning on adding a small greenhouse within a green house similar to what you have. My thought was that if I kept the space small enough I could add heat and lights and use the new space to start the seasons seedlings and starts. Our primary income was from tomatoes and strawberries. During a normal hot summer we average around 2500 lbs of heirloom tomatoes per green house. I would love to hear about your production levels

Thoughts for others greenhouses in winter. Air BnB for seminars, glamping, part of green house has platforms to assemble for preventing compaction of planting beds and warmth for people. Weddings in winter - once again platforms assembled to protect beds and clothing. Grow fodder to feed your chickens and rabbits. Chickens don’t lay eggs until they are 16-18 weeks old, grow out babies to layers, between fodder and fermented feed it will be cheap to feed. Any rooster become dinner for family and others. Any cattle or sheep ranches near you? Fodder is great for cattle conditioning, same for sheep 🐑. Fodder is growing barley (usually) from seed to 7 days. Maybe a little longer in Alberta. At 7 days it is fed to animals for maximum nutrition and palatability (taste). Excellent weight gains and conditioning. Sell fodder to cattle or sheep ranches. Cost is usually less then hay. Just some thoughts 💭

This is pretty amazing. I live in Winnipeg, Manitoba and our temperatures are very similar. I wish I had the yard space to just have a small greenhouse. I do mainly raised beds as I just don't have the space to do anything else. I think it would be pretty neat if there was a way you could track both the outside and inside temperatures over the course of a year and graph them out to see how they look.

Maybe add a solar thermal collector to your geothermal heating system, maybe store the hot water underground to use later in when it's the coldest. I've seen people pipe warm water through the floors of their homes using relatively small thermal collectors they made themselves, and it saves a lot of money heating the house in the winter, and the floor is always warm and the heat rises so you get a better thermal gradient throughout the home too (good for off-the-grid setups too).

Thanks for sharing. I used wood chips in our southern Alberta greenhouse 25,000 square feet. They were primarily softwood chips. I had used peat and manure but found chips to be the best. I used water soluble fertilizer but no pesticides ever. We collected our own predators and bought when the weather was bad. I noticed a lot of salt or calcium crust on top of your soil. Are you using foliar or soil tests? You can contact me directly if you like. I've been in the horticulture business over 35 years and have had three greenhouse companies. So I've made my share of mistakes.

I would think this would be a perfect application for a cheap backup heat source like a wood stove. Shoot, even a minor set of grow lights would provide enough heat to keep the plants from freezing and also provide some daylight for those days when you can't open the blankets. You don't need enough heat to keep it 20 degrees, just keep from freezing. I get your point about the expense of such a large greenhouse, but wood heat is quite cheap. Anyway, I admire what you're doing. It may prove to be necessary for our survival at some point in the future.

a 80m long greenhouse costs about $100k CAD, incliding all the parts, shipping to Alberta and tax

@@dongjianyi2492 Thank you for the very useful information. Some great videos in the future might be a time lapse video of the construction of one of these greenhouses and / or an explanation as to how much labor and skill goes into assembling all the parts that come from China. It would also be interesting to know if smaller greenhouses are available. For example perhaps a 5000 sf greenhouse that requires half of the steel supports. Loving your videos. Keep up the fantastic work! :-)

Amazing work, thank you for sharing these updates! I'm curious if you have considered growing citrus? If your maximum low is -2c some of the hardier citrus types like Improved Meyer Lemon, Yuzu, Dekopon, Mandarin may be able to overwinter inside the greenhouse. Also maybe figs, pomegranate, olives, feijoa/pineapple-guava, etc

You should look into waist oil drip stoves. You can sometimes locate sources of free waist oil. And you can build the stoves yourself for low cost. The only continuous cost would be to run a fan for forced air. I will be using one to heat my house as well as a goat barn here in Alaska.

I would love to do a simulation of this type of greenhouse, do spectral optimization of the foil to maximise light coming in, squeeze the last few percent of performance out of this design. Maybe if one day vacuum panels become cheaper you can have even less temperature loss at night. Inspiring video.

Dong, have you seen Citrus in the Snow? Veggies may not payout with a heated green house however, Citrus in the Snow talks about the profit margin gain from selling citrus in Nebraska locally. Also switch to soil blocks instead of plastic trays to prevent root binding which leaves plants weak and susceptible to bugs/insects. Check out Eliot Coleman also, pioneer of 4 season growing! Hope to see your stuff in organic isles soon!

The use of systems that heat/cool the greenhouses is for increasing the yield and it should pay for it self. Anything that have the result that income is increased more then the cost is something worth doing. The area where I live in Norway produce more then 70% of the tomatoes sold in Norway and all are grown in greenhouses. Since we are so fare north added light and and system that protect against low temperatures are important factors in ensuring the profit for the growers.

old canadian farmer trick. ussing biomass from the farm and some cow shit one can make a cheap and easy heating system ussing the heat generated by the composting of the material being pumped in via a insulated hose.... easy to make and implement
