Thank you Curtis I for one truly appreciate your effort in provide information to the general public your up to date pertinent info on raising and cultivating produce products I for one am very interested in a walk behind large harvesting tool please keep us up to date your great Curtis thanks a million keep up the good work
I hope you built the greenhouse in East-West orientation to take advantage of Southern exposure and be able to insulate the North side to conserve heat during the winter.
Nice video explaining GATH system installation with details. I have a question. What is the final result? Does it work as per expectation? How was the temperature inside at night as compare to outside temperature in winter? Please help because I also want to build GATH system.
Thank you for checking the video out. I do not have any of the data on this as we installed the system for a customer Roshi Alpha 1. I have been receiving a few of these questions so I may try to contact them and get some info also. Thank you have a great day
Great video! Thank you for sharing this energy efficient build.. Can you please tell us the dimensions of that greenhouse? Peak height, length and width would be greatly appreciated.
Any update? How the systems connects and how it works? Temperature comparison of the greenhouse and the outside? In the growing season. Subscribed and looking forward for your interesting designs.
Yes I spoke to the people that designed it and actually are growing inside of it and they said it is working tremendously efficient. The plants are flourishing.
How long is the break even time on this project compared to electric or gas heating? What's the lifespan of the GAHZT system? It looks amazing but it must be terribly expensive to install.
big question is how long those wooden planters will last... considering this is commercial production, why not to make them from galvinized steel so they dont fall appart in 10 years?
mbchudno Good observation. That was a separate contractor that did the planter boxes and whatever else on the surface for the owners of this greenhouse. We were the underground system installers and water diversion installers. Thank you for your comments.
Dear Sir i love what you guys did, and since im an Architect i would to to involve myself in donating that knowledge to everyone on the Internet by providing you with detailed 3d architectural drawings so everyone can understand, If you are interested can you kindly send me your email . Thank you great work.
My situation is different than many people. Most have green houses to keep their plants warm longer into the winter. I live in southern Utah and our low at night in the dead of winter usually won't go below 25 degrees. So a green house can easily be kept warm all winter long. However, the middle of summer scorches flowering plants and the temps get to 112-118 degrees outside for about 1 full month in the year make outside vegatables impossible to grow. Can this system cool to below 90 degrees in these conditions?
Not really sure. This system was designed by a company in the midwest who was building another greenhouse out here in Oregon where our temps look pretty close to yours. We built the system around their specs.
@@hukillsinc Theres no way the design in the video will keep the greenhouse cool in the summer. The tubes are too long and the headers wont handle the required flowrate
Do you have a vdo of the connection of the pipes and functioning of the geo thermal system? Pls do share if you have one and tell us if its effective. ..thank you
With these GAHT systems, there is talk of hot wet air going down and condensing in the pipes underground. I have not seen anywhere yet how the pipes are drained of this condensed water. Would not the water build to a level where the pipes are full? Also I have seen polystyrene become saturated in water. If this happened here, would that not reduce its insulation value. Or is there closed cell products that are suitable for this task? Also looking forward to seeing this system in working order.
Using a much bigger excavator without the greenhouse installed would have been way more efficient . And have you done any follow up videos of completion ?
How much does something like that cost? I have a 96x30' greenhouse and am interested in using it for aquaponics, but it gets too hot in summer and too cold in winter.
It exchanges air well But you really have to monitor how much water you put on your plants and do not over water because of how much water will drain through the bottom. I would probly change to a perforated PVC pipe and more gravel in the soil that is backfield in layers rather than all dirt around the pipes.
awesome work. what effect does this have? is it comparable to a wet wall for cooling with the bonus of heating in the evening. How many degrees can it raise temps at night?
Is it better to use solid or Perforated Pipe in the ground and do I have to worry about burying it 8' in the ground? Please help me on this. I don't want to have to redo this project over. I don't have the finances.
absolutely not! perforated pipe also condensation to be leached out and the ribbed pipe adds 3x the surface area. perhaps this video was made prior to these awarenesses. tho the intent was good this seems like a video of how not to build a gaht system ldsprepper or at isadores farm have exceptional and proven results from a superior design imho
I just received this information back from the people running the greenhouse. They said It is working great! We do not need to use any dehumidifiers in the GH at all. Temperature stays controllable and in the colder months at beginning of season required minimal propane heating. They also stated this is first season in use and more data is need to establish any cost saving numbers.
Depending on the soil conditions and where the dirt can be stockpiled on the outside of the greenhouse and what the surrounding water table is like it is around $65,000 for a 35 by 100 greenhouse.
Great question regards cost. Answer was $65,000 for 35 x 100 ft. Here's another one. What has been the cost to Americans for trying to protect the sources of Middle east oil? Imagine cutting the military budget by 10% and spending it on infrastructure like this ? :) Never going to happen. Watch any Chompsky doc and you will see why it's important to the uber rich to keep us out of free energy. This is an awesome project !
Interesting. Do you have any greenhouse temperature data to show actual performance of this system over all four seasons? Anything online that we can see?
@@hukillsinc Looking forward to seeing actual temperature historical data on this interesting & important project. In order to truly analyze & model the thermal performance of the system it is necessary to collect greenhouse air & soil temperatures (humidity also helps) AND outside air temperature. Even better, constant logging of greenhouse environmental data that also includes light levels AND an outdoor weather station that collects air temperature, humidity and wind speed. The best monitoring would also include any backup heating & cooling system energy consumption required to maintain optimal greenhouse temperatures during extremely cold or hot outdoor weather conditions. You might be able to collect this data by modifying the inexpensive Open Energy Monitor system (www.openenergymonitor.org) to interface with an inexpensive home weather station. With some free open source building energy modeling software it should also be possible to model the Geothermal GAHT system and then compare predicted performance to actual performance. This analysis might suggest where further improvements in system performance might be found and how to size any improvements to reach targeted performance goals. (So glad that you are pioneering this important work with the Geothermal GAHT system for use in greenhouse heating & cooling - it is very important to the future of renewable energy use in food production systems.)
@@johnsilvernale6472 The physics implies that the only way this system could work is to fully insulate the climate battery on all sides except the greenhouse floor. Stored heat will have a tendency to conduct away from the recharge zone and thus dissipate into the earth outside of the greenhouse internal floor. Ground water passing thru the climate battery will drain the heat energy away even faster. As someone with a science background, what I want to see is the actual recorded temperature data: inside, outside, and in the climate battery. The data will tell us whether this system actually works or not...
So much work into the base, then it looks like a single layer of plastic tunnel. what a waste. This only makes sense if they had a real greenhouse or at the least, a double film (with blowers).
@David Lutz Google greenhouse in the snow Russ Finch has a similar system for about $25k. Not the same dimensions, but grows citrus year-round in frigid Nebraska.
@@jake.presents True, Russ is genius. What is nice about that system is that it is 8 feet down x 100 feet long outside. No insulation needed and it keeps the greenhouse closer to 57 degrees F. All you need to do is dig a looong trench and no manifold.
@@hermanv.b.376 Build a greenhouse just the same as see if you can keep it at 57 degrees all year round. Installing 2900ft of tubing just to run a pitiful amount of air through it is a waste of time and money.
You want the air to be able transition with moisture in it out into the soil where it will hold its heat and then use the heat depending if it's day or night. Otherwise the air will just blow through the pipes and not heat the soil around it.
@@hukillsinc Latent heat makes up around 60% of the total heat transferred into the mass during cooling. Be aware that latent heat in the form of humidity will be transferred back into the greenhouse when heating. You`ll see it reflected in the greenhouse RH%. It can be problematic, especially at night when the RH% is typically high to begin with.
It's a great way to store solar heat for winter and cool during summer. A simpler system in Nebraska grows CITRUS year round. Perf pipe and dirt is cheap compared to the yearly cost of natural gas or electricity for heat/cooling.
But the system allows to grow citrus in the snow. The ideia is very good but expensive. On the other hand, you do not have to use so many machines if you have a lot of robust friends :-)
Ryan Sark Thank you for taking the time to share your comments. There was no salesman that sold this project. This was a project given to our company by the owner of the greenhouse and installed per their designs. This was a system that they wanted to install to try to produce better efficiency in their greenhouses. Beyond that we do not sell greenhouses or designs for the systems we are excavation underground contractors that do a multitude of different projects customers request. But thank you again for watching and taking the time to comment. Have a great day.
Ryan this is very very critical and you offer no pointers as to what could be done to improve the situation. I plan to build a passive solar Greenhouse in the next year or two and I'm researching everything. One comment I will make which I've read online is that gravel Does a better job of absorbing heat then soil does by a factor of 2 I think. Therefore they probably should have used gravel instead of the soil for backfill. But then again as a contractor myself building koi ponds for the last 25 years ultimately you do what the customer wants and or what the budget dictates. It's not always the best or most ideal.. it's great though that they took the time to share this video because there isn't a ton of information out there on this technology
@@rickyclerk3700 I did not mean to come off disrespectful but compacting soft soil on corrugated tile seems problematic, we excavate crushed tile all the time. Sleeved tile works the same as solid tile its just more expensive, I think geothermal techniques will be the future of efficient construction and any effort put forth will be a learning experience. Thanks I enjoyed your video
@@ryansark1795 good information. Certainly the immense weight could crush the pipe depending the mass (depth) overhead. Much more productive then merely saying red flags everywhere so thanks for that Ryan. Cheers
HappyDeux We don’t grow anything. We are an excavation plumbing company that provided the installation per the owners plans. But I have reached out to them asking how it is working and waiting for a reply back. Thank you and have a great day.
Thank you for your input, but the owner of the green house has seen tremendous success with this green house and the system that we installed per their designs and request. The work you see being performed actually happened no trick photography. But thank you watching and commenting.
@@hukillsinc Hugh Lovel has studied soil biology for 40 years. He took over a farm with the most depleted soil in his county. By working with soil biology he grew an inch of soil in the first year. And 5 inches in the second. If you grow food in pots you will never experience the miracle of soil biology. Dr Elaine Ingham said, "Suppose a leaf 100 feet in the air decides it needs Calcium. It sends a message in chemical form down to the roots where the message is relayed to a co-operating fungi. The fungi delivers Calcium. The fungi paid by in exchange for sugar made by photosynthesis. The Calcium is sent up he ree to the leaf. The round trip takes 90 seconds. " Soil Biology is grand.
