This video demonstrates how you can grow during the winter in a 4 season greenhouse in Colorado. For more information on growing 4 season please visit our website www.diyfarmer.com
Don't know if you read,Don't know what happens last 9 years but this video was great! One of the best I saw the last years. Hope you as family going well. Greets from a Dutch
Thank you for this video. I especially like the part about your blower which blows air between the layers of plastic. Could you please give more details about that? Do you have more videos?
This is the first time I saw one of your videos and what a great find! Can't wait to see more of them. I love how you integrated the family and humor into them. Well done!
Finally! Some one gets it, ventilation, it's very important. Most of these green houses have rather poor to zero ventilation. Gotta keep the air circulating and not let the moisture build up too much.
I got my greenhouse from Walmart for only $115. I just put it up, but man, it is already super hot in there. I love it, I am pretty sure I can grow during the winter with this.
winter conditions have stirred my thoughts about purchasing land specifically for greenhouses. This video really helped me get an idea clear and settled my anxiety. now all I need to do is learn how to knit.
We have the same kind of greenhouse, but we don't have a vent on top, which I think is awesome. We grow for the farmers markets and it's really important for us to get a head start for the tomatoes, peppers and so on. Last winter we had a lot freezing temps, so we had to crank on the heater which did cost a lot but was well worth the cost. We had a amazing summer this year. Thanks for posting....Take care
can you show more details about where to order , build up green house......all your information very helpful for beginner like me to learn grow green all season..thanks
i dunno, they seem like they would be happier if we 'made' them into boys, or eunuchs. whatever will decrease the white population, because thats social justice n all
Great video! Love the double wall idea. First time I've heard of that. I was going to use composting leaves and manure but I like this much better. Thank you!
In my experience, unless you have thermal mass like water bottles, two hours after the sun goes down the inside temp equals the outside temp. Things like celantro or spinach do fine, but even they might need a coldframe inside the greenhouse. Massachusetts winters, same inflared double 6 mil plastic.
Are you saying the 6 mil is what you built the greenhouse out of or what you put overtop of the coldframe? The passive water heater is a good idea, and just have your cylinders give off heat at night. I'd like to see if I could get a thermo-siphon going between a solar-heated tank and an insulated tank, up high. Use the sun's heat to warm and move the warm water up to a higher tank, and then use gravity to bring that warm water to pipes under and maybe on the surface of the soil, in cold frames inside of greenhouses. Won't take much to knock the chill off the roots and small air space, especially if you use insulated covers on your cold frames that open the insulated lids when the sun hits them. Or you just go out when you know the sun is hitting them! I like to sit around thinking about how to move the water uphill, with few moving parts. Maybe a decadent fish/wading/swimming pond/pool in the solarium with a cool space up high, under the berm on the North side, where the air cools down and the water condenses out. Need to do the math on how much water you could move with a large-space, low-intensity water distillery. If the space is very large, the surface area of the pond is large, then you could port climate-controlled air to relatively small spaces where humans and plants need them. If you think of these glass-enclosed spaces in sunshine, it stands to reason that as a heat engine, they could do more work the bigger they were... Personally I think the Russ Finch design is a little too tilted towards keeping it in PLANT range and not comfortable human range. During summertime tours, temps in the Nebraska passive geo thermal greenhouse were up in the low 100s. And they had some BIG fans. He still sees significant savings with the passive geothermal, but I don't think he makes it the human's favorite place to hang out. I kind of want "mine" to be more integrated into the living space, with more thought for cool comfort in the summer and the best room for playing music in the house.
I've heard that adding a compost pile to a greenhouse can serve as a source of free heat. Since you get lots of sun, a couple of black barrels full of water might store enough heat to take the edge off on cold nights and boost production.
Giving that kid such a tongue twister was not fair. She couldn't have knit for something else? lol Nicely done video, some really good comments on it, too. I also want to do hotbeds, but not 100% convinced yet they're worth al the work...especially if I lose my compost-fuel source.
Double wall is just two sheets of 6 mill put up as one, then inflator blows air in between them all the time. Two hours after sun down Inside will be outside temp without a lot of thermal mass. Canada would need heaters or inside coldframes with water bottles. About 110 degrees on a 20 day in Massachusetts while sun shines. Then when the sun goes your heat goes fast.
Hello I was searching for other channels like mine and I came across yours. I am gathering information on greenhouses. I subscribed to yours and cant wait to watch more videos.
Sir... Don't know what happened to you .... But a 7 yr old video and not another one I hope all has been well... Would have loved to seen more in these bad current times....
Since you don't heat your greenhouse, why not put 3 black drums filled with water, one at each end and one in the middle to keep some heat in the greenhouse? The drums will release the stored up heat as they cool.
Dig some holes, 4" pvc deep into the ground. Fill w rocks. Fans pushing air down during the day, air out at night. Same concept, except geo-thermal-ish. Solar powered fans.
every winter makes me desperate in the green house. I barely keep 46 or 48 fahrenheit with many heaters which consumes 5kwh while 30 fahrenheit out there. also the place doesn't get enough sun light in broad daylight. because there are several tall buildings surrounding the green house. after watching your video then i reached a conclusion. it is adding more insulation layer in it.
Ever see how the Chinese do greenhouses? They do the same as you with the double layer except the second layer is 6' above the first layer and there is a roll top desk sort of contraption at the top that rolls down every night in between the two layers made of something similar to concrete blankets to keep the heat from the day from disappating away at night. Their tunnels are only 5/8ths of a semi circle instead of a full 50% semi circle. The opaque plastic allowing sun to come in faces south while the north facing mass wall is made from sedgehammered earth and tires in a brick or adobe style matrix. It keeps the cold out. But before they even build the greenhouse, they dig 12' down on the footprint of the growing area and insulate everything except where the roots will be and then fill first with perferated drain tile then #3 stone and sand. On top of that goes a layer of logs that were either misshaped or discard like stumps before compost and soil amendments finished the plot. One end of the perferated drain tile sucks air from the very top of the greenhouse whereas the other air that blows into the green house is installed near the ground. It works well that system. Frostless nights when its -50. Ah well if you've ever witnessed a chinese contractor replacing vinyl siding on a four story house in a Chicago neighborhood... I shit you not there were 150 of them on the site for a day. They had everything tore off, re wrapped, windows trimmed out and re sided in one day. There was a crew of 30 that came and cleared all the debris and were gone by lunch the second day. So, I guess when the manpower and rescources are available...you can get a whole lot accomplished. 🙄😁😊😂
Have you considered adding barrels of salt water or something to increase the thermal mass of the greenhouse? That would help to level out the temperature swings...
I saw a video of some guy putting fish in these big square plastic water containers that are in metal cages and painted them black. Forgot what those are called. Anyway, he had 3 of them and had a pump connecting them. Passive solar. Even used one of them for watercress. You could use 55 gal plastic gallon containers painted black for passive solar as well. Also saw him dig out the trenches along the rows and put wood on top and used them for compost and worms. I'd worry about mice though.....
Actually, it was a combo of aquaponics and soil. Kind of. He just used the water not only to grow fish and watercress but to heat the greenhouse and to also fertilize the soil. i think using that kind of formula really seems to cover all bases maybe.
big square plastic water containers= (IBC)Intermediate bulk container. - wiki that - And there is no need to paint them black, as you need new ones anyway and there are black (made from black plastic) ones arready available. for passive greenhouse heating search "Jean Pain", former french lumberjack - wiki that also - build - grow - enjoy
A double wall poly green house is only a little bit more R value than a single wall. If you are going to actually raise plants in the dead of winter you must have heat and lots of it. When the sun goes down it gets super cold in a matter of minutes. I used to have 20,000 Sq ft of commercial greenhouses and stressing plants, even cold tolerant crops with temperature swings like that aren't going to grow well.
Many crops depend on a temperature constance like tomatoes ... They can grow great if daytime is 70 and nights are 50 ... With your temperature swing ( 89 to below 32 ) it is a wonder anything grows ... Seems like 89 or even over 75 every day in the winter would make spinach bolt to seed really fast ... I know lettuces would ... So would braccias ...
With your double layer plastic walls, how do you keep it sealed up? I'd imagine it works similar to those inflatable funhouses, etc, so how do you keep it air tight( or close enough to it to be effective)? Great design! Thanks in advance!
I still don't know why they don't just fasten plastic inside the frame and outside the frame, to get a few or sevral inches, that way. You could make a relatively spindly inner frame and give yourself 3 or 6 inches or maybe more. I don't understand the fascination with having blowers, although I suppose it might be cheaper, up front. Just seems like a system that's begging to fail at some point. Also don't know how much power the blower uses. I also wonder if you could use a pretty low-intensity heater to warm the air between the layers, so that the inside of the structure doesn't lose any heat, because it's in contact with the ground and a relatively warm outer layer... I'm almost certain that I'm violating the laws of thermodynamics, somehow, but if you could circulate warm air between the layers, it just seems like the inside wouldn't be losing heat to the outside through that warm(er) shell. Of course, I've given zero thought to how you'd distribute the warmer air throughout the air sleeve. I really like the down-to-earth, "grow crops that are cold-tolerant, you ninny!" approach. But that still doesn't get you to citrus in winter, the way some want.
Really Really nice. I don't have a lot of backyard, but want to build a decent size greenhouse to grow some vegetables. If you have any DIY videos for somehing smaller, please share thank you.
Awesome! I really like the warm/refresh system. We should use it over here because in our aquaculture harvest the water temperature control is very important for good results on it. By the way, may you enable the subtitle translation for me translate that and can offer for my frinds after help your channel? Thank you
So it DOES freeze in there? Oh, at night- it is warm but at night it freezes? I have never lived anywhere but Texas. I am in Central Texas now. I have 2 kind of leaky small greenhouses. 1 is a simple lean to against my house with used window and a used door and 3 used sliding glass door panels. I just put a portable electric heater in there and occasionally turn it on in January or February when we have a little cold weather.
+Betty Saenz Surprised you aren't using a heater that has a thermostat to automate the process and maintain the desired temperature. Seen a few videos for greenhouse projects that recycled glass hardware.
Two questions: I'm in Boulder, what Colorado do you live in? Don't think there's been 200+ days of sunshine since 2013. Also, why would veggies freeze if it's 89°???
I like the video but more info needs to provided such as cost of the greenhouse and what it needs, timeframe and laws. As each states have their own laws/regulations. But nice video
I am in the planning stage for a build of a four cattle panel green house. How do you ensure pollination is happening in your green house? I know you have vents, but I am not so sure vents alone encourage bees to enter or not. I plan to make my floor a raised bed and it will be a 4 panel, 8-9' wide house. It will sit on a 3' framework of 4X4's, so the height should be adequate. I am toying with the idea of a composting area being put to the outside north wall and heat from that used to be pumped into the green house. I learn something from all these videos, even if they differ from what my plans are to be. Thanks for sharing.
