Growing Spaces "Year Round Greenhouse" Build...will be a Game Changer!

- Building in the mountains has many layers of complexity, from permitting to building specs and county requirements. Our next major project is building our Year Round Growing Spaces Growing Dome (Geodesic Greenhouse) and we are actually on schedule. Despite the challenges, we are moving forward and spending more money to get things done quicker.

How exciting! I look forward to witnessing your progress!
Thank you!!
I admire your ability to deal with the most inconsistent weather I’ve ever witnessed in my life.
Say hello to climate change!
It's a little erratic, that's for sure.
Should be a nice project to build and complete.
We are super excited!
This is going to be a fun project to watch. I like your channel and I like the concept of this kind of build. Staying tuned in!!
Thank you very much!
I know about the large number of stone issues you have to deal with. When I would get frustrated with all of the rock work we had to do back when my family was digging out for the foundation of our home at the top of Crow Hill near Baily Colorado my dad would remind us that they ARE called the "Rocky Mountains" for a good reason.
hahah that's funny! but true
👍 yay
yes!
Meease
haha! yes!
Supper pleased your getting your geo thermal greenhouse.amy I know it's something you have logged for.very best wishes for a successful build and bumper crops in future. Michael uk care home resident
Thanks, you too!
I'll have to stay tuned in just to see how those forms work. Didn't follow that at all. 👍
it's like how we did the basement, but it's always easier to explain something when we're actually doing it, to demonstrate
Great to see the weather is letting you get started on this project. Very exciting to hear and hopefully all goes well.
We are happy with the mild spring so far.
R u going to get back into bees to help pollinate your green house?
Probably next year.
класный проект.
Thanks!
The hand gestures suggest you may be planning to use a serpentine tube layout, which should be avoided at all costs. You should be aware that the heat returned by the system will contain a significant amount of water vapor which will only serve to increase the greenhouse RH%, not the temperature. A greenhouse with humidity in excess of 90%, especially at night, is not ideal. Any surface, such as glazing, timber and even the leaves / stems of plants themselves that are below the dewpoint temperature will be subject to condensation. Condensate will tend to run down the glazing and sit on top of any horizontal struts that are angled back towards the glazing which act like a trough. This can lead to black mold on the timber and ultimately rot. Condensate dripping from the timbers onto the plants below can create a lot of issues. You can use a dehumidifier to mitigate this situation but, in most cases, it will need to be the more expensive desiccant type which are able to operate at much lower temperatures than the standard domestic dehumidifiers.
Thanks for the info. Are you suggesting another type of tubing? Is humidity relative to geographic area? or just the fact that the air is drawn from underground?

4" corrugated tubing provides the best bang for the buck in terms of cost, surface area per unit length and, as tubing displaces mass, the amount of tubing you can install in a fixed amount of mass. The number of tubes, length of the individual tubes and the layout has a massive effect on the performance. Humidity is both a blessing and a curse. Its a blessing when the system is used for cooling and a curse when its used for heating. Most folks will understand that when the system is used for cooling the air will drop to dewpoint inside the tube forcing the water vapor to change phase from a gas to a liquid (water vapor to liquid water). The water condenses out inside the tube along with the sensible energy used to provide the initial phase change from liquid to gas (liquid water to water vapor) is released at the same time. When cold air runs through warm tubes, sensible heat is taken from the mass to supply the energy for liquid to gas phase change (liquid water to water vapor). The air leaving the tubes contains both sensible and latent forms of energy. Only the sensible component will raise the greenhouse air temperature, the latent component will only raise the RH%. The sensible energy taken from the mass is effectively "spent" on raising the humidity. It takes roughly 1000btu of sensible energy to evaporate 1lb of water. Every pound of water that condenses out in the tubes releases roughly1000btu of sensible energy. If you monitor both the inlet temperature and RH% and outlet temperature and RH% of the tubing along with the flowrate in cfm you can calculate the total heat transfer, the sensible and latent percentage. If you also measure the fans power consumption you can calculate the system COP (coefficient of performance). I`d recommend installing temperature sensors in the ground both inside and outside the greenhouse and at least one several feet below the deepest tubes. Hopefully some of this was useful.
@@JohnGuest45thank you for your generous sharing of information- you’ve given us a lot to think about and valuable guidance.

Looking at tubing and fan prices in the states, 1100ft of 4" tubing and sock will be around $1500, a fan capable of putting the entire greenhouse air volume underground upto 32x an hour is another $300 or so. With speed control and thermostats, you may be looking at around $2k which isnt too bad :)
