Greenhouse update (Nov). Insulation, geothermal heating and cooling, and more

This is a Greenhouse we are building in Springville, Utah. We purchased a Kit from Greenhouse in the Snow and have added various fans, vents and shade cloth from greenhousemegastore.com. Its November and we are gearing up for cold weather. Insulation and electrical are finished. Geothermal is almost finished. Sneak peak of our Aquaponics. Lots more coming.

You mentioned you will put chicken wire over the box for the geothermal pipes. You should use 1/4.inch wire mesh to keep mice and other critters out of the pipes.

[@investwave7262]

I have some experience growing indoors and what I would recommend is smoothing this surface inside and painting white or even better, adding mylar foil. This will reflect the sunshine better so your plants will be getting more light.

[@The_Endo]

'some experience' lol... my guy 😏

[@brianlavoie3867]

Good to see this, we will be building one next year, using hempcrete on the north, east and west walls. We are off the grid and looking at Snap fan for direct solar connection on ventilation, but have not figure out the blower fans as they use so much more power. Hoping the hempcrete will be part of this solution as it acts as a thermal battery to help keep it cool and warm. Cheers!

[@neildalesongs6503]

I'd love to see how your greenhouse is operating now! I have a prediction that you will be able to answer by now, which is that the water table may keep the temperature in you geothermal pipes at a constant temp in the 50's, rather than build up a "heat battery" over the course of a few years, as it seems to do in Russ's greenhouse. That might keep the greenhouse a bit cooler in the winter than you expected. I'd also like to know what kind of soil, and at what height you planted those fruit trees. I hope they are doing well!

My greenhouse in northwestern Utah County has about a 3 ft deep hole in it, and it filled with about 2 feet of water late last winter (circa feb 2023), with all the snow and rain we had. Mine won't always have this hole and the floor is at ground level, but I imagine by now you might have added a sump pump to keep the water seapage under control...

[@trailbreakfarms]

last Winter was very unusual. I didn't have any problems but we were very wet with the Spring melting and moisture that never ended. Sump would be a good idea if the problem persists.

I still wonder if the mass actually works on that oranges-in-the-snow idea. But the old man insists you get ground-temperature-average out of those hoses if they're at least as long as that magic 230 feet and buried 8 or 9 feet. I'm just not sure I'd do in summer what they do in summer. I think summer mode for my greenhouse would be mostly idle, and I'd grow beans and such on trellises outside, and keep most/all of the sun off it. I'm debating whether to move the citrus inside and outside, seasonally. But I can see keeping that space cool in summer with shade more than with big blowers. I know nothing about the root system of such trees, but I'd definitely look into moving them outside in the summer, or only letting the sun in where I had my indoor grove, and shade the rest of it. To me, the purpose of the greenhouse is to grow things in the cold. And just about everywhere that guy had aluminum siding, I'd have earth, I think.

So you have two geothermal earth tube systems? One that pulls air through your yard for fresh air. From where? And how does it drain condensate? Then a second system that recirculates the air. Where does it drain condensate? As you can tell from the graph on your video, most people come here to learn about your earth tubes and it would be nice to know more..

[@lynnmoss2127]

we have a high water table here too, maybe even higher than 7'. My concern is water eventually seeping into the air tubes and creating mold, and thus creating an unhealthy air quality, for humans, in the greenhouse. I suppose the alternative would be the different geothermal style using fluid-filled tubes. What do you think?

[@trailbreakfarms]

interesting idea. I'm not familiar with fluid filled tubes.

Very cool! Thank you for sharing! Subbed!

[@vidalott]

Looks good. Instead of covering the berms with siding you could run three rows of horizontal shelving, at an angle, to grow your favorite table vegetables. It may increase the temperature slightly. So, if you are having excess heat issues, then maybe not. However, in my opinion the benefits of an increased rhizosphereic profile are worth it. Maybe through in some mushrooms? The pond is really interesting. Never heard of such a thing. You kinda made yourself a spring. What are the rough dimensions/area?

Growing area is 17 x 72. My plan is Vines on the North Wall Grow beds on north and south. Trees and shrubs and ground cover in the main area. Mostly tropical fruit. Regarding back up, I am going to put a solar unit up next year but our power has been uninterrupted. I have thought about putting in a back up heater that runs off a propane tank in case of outage. Right now I'm using geothermal and a back up electric heater to keep it at 50 and above during winter. My next video will show how I heat and cool the GH during winter.

[@trailbreakfarms]

Water has stayed atleast a few feet below the Greenhouse. We ended up picking up a lot of water in the trench where we placed the geothermal so we put in a new trench heading downhill from the pipe trench and that has picked up a lot of water and places it in a pond where it can slowly percolate into the ground from below. Cool pond. It doesn't freeze during winter because it has a constant inflow of new water.

[@keithshoemaker6034]

Why did you choose not to build the back side into a hill using the earth to insulate backside? Or northside of the house.

[@trailbreakfarms]

My Property rises slightly from West to East. Definitely would be best if you had South facing so you could build into the hill. Also would be best to build on South side of a structure so you can exchange hot/cold air between structure and Greenhouse. The South side of our shop is in the shade for a good part of the day.

If it's not letting sun in, I want to see earth coming right up to it, to the maximum extent possible. Maybe yours is the compromise build that'll keep kids from climbing on it. But it seems like you'd want to max out the advantages of earth shelter everywhere the structure is opaque. So at the bottom level, you'd be something like 10 or 15 (more?) feet below the top of the berm abutting the north wall of the build, because you're digging down a few or several feet and you're piling the debris on your north a few or several feet. And yeah. You're giving water much better places to go than your construction. The value of a good excavator is not to be underestimated. .

That is an AMAZING greenhouse. I love it. BUT.... With having to have big machines do the dig out, the purchase of the green house kit, all the electrical, fan, air Iping, spray foam, and everything else that went into the construction and then what will be needed to run it and maintain it yearly... you have about $50,000 into that build!! How much produce (only as that is all you can grow in a green house) can one buy from a store for $50,000? How many years of produce will $50,000 get you? I get the whole "self sufficient" thing. Heck, I wou.d love to have this green house myself. But $50K just to grow produce? Per year I bet I spend maybe $1,000 on just produce I could grow in a green house. That means if just kept that $50K instead of building this amazing green house, then I could buy produce for 50 years!! In 50 years that green house would be falling apart. In 10 years those plastic panels will dry rot. In the next 10 years half of those electric fan motors will stop working because of the dusty and most environment. Again, Amazing green house and I love it, but I can see how much money you have in there and it is just not worth it. A homestead green house should not cost more than $2,000 to build. More than that and a person is just being silly with their money.

Very good comment. Here's my thought... I'm into this $35K. My goal here isn't a financial return, but to get educated on Greenhouses, Solar, Aquaponics, Geothermal, Growing year 'round, Self sufficient, sustainable farming, etc. Also, I want to pick my own tropical fruit, not buy them at a store where they have travelled thousands of miles. And, most important...I want to live longer, healthier, happier. If I do this, it's a priceless venture. I didn't do this for a return on investment. I've done that elsewhere. But, if I did, I'm confident I could get a return on this Puppy!. I've had a Restaurant Owner tell me they'd buy everything I could produce. I could take excess produce the the local Farmers Market. I could eat everything else. I've had requests for tours, classes, consulting, even requests to build for others. I could monetize KZbin. Literally the sky is the limit.

We have some other things we'll try out including more tubes. Once the trees and plants are fully grown, that'll help a lot. We'll keep you posted.

Nice summary of your build. I stumbled across this video yesterday kzbin.info/www/bejne/h6fOaIapr81pnMk . Good explanation of seasonal sun angles and it’s especially interesting how he uses 55 gallon barrels and a gutter to capture rain water. The barrels also store heat when the winter sun is low on the horizon, releasing the heat at night.

I live in Utah and am probably going to build one of these down in Monroe Utah, any chance I could come get a tour of what you did?

[@trailbreakfarms]

yep. I've been doing a tour usually once a month. my email is [e-mail]

Did you use 2 layers of plastic and have a blower blowing air in between them?

[@trailbreakfarms]

no. the blower I use pushes air thru the geothermal tubes.
