I advise you to put some plastic inbetween the stones and the wood in 6:55. It will prevent the wood from rotting because of the humidity from below.
Great work, thanks for posting!
Great solution on your tank problem. I would have probably got mad and knocked it all over with the tractor bucket lol. Great work!
@MrPVaSoldier electronic engineering and computer science...and I worked for a civil engineer for a while too. ;-)
You have made my life a lot easier. I'm building a rectagle solar greenhouse this year, and your videos are going to be of great use. Thanks bro, and fatastic work!
Yeah!!!! I was happy dancing for you when that plastic tank cleared everything. So happy for you. Thanks for sharing.
@ddnguyen278 The exhaust will not go through that area. I'll install some kind of heat exchange and blow only fresh air through that part. The exhaust will go outside where it belongs. Thanks - good question.
@Mooja12 If the ducts are too low, a lot of the heat will bleed down into the ground and out under the foundation footings. The footings drains around the building will keep the natural ground water out. For the most part, the dirt will stay dry. It's the moisture in the greenhouse that is the problem. Powdery mildew grows like crazy in my other one!
@tenj00 The boards there were temporary just to fit things. There is a layer of closed-cell foam that was placed under them. Also this is treated lumber which is rated for direct burial. I believe it's rated for 40 years.
this wind isn't bad here at all. There's an anchor every 4 feet or so. We've had to hurricanes here so far...still standing!
Sorry. All the music in these videos is royalty free. The 12 dome videos can be found over on Vimeo too.
You've done such a great job of documenting this process, Rob. Thank you so much for doing so - it is such an amazing and inspiring process to watch.
the water line is at 900 gallons. It's a bit large for this system but helps to keep the fish density lower.
What kind of farm can afford to drop $100K on a tractor? THAT's the kind of farming I'm glad I'm NOT doing.
There's foam between the concrete and the wood shown at 10:00. It's also treated lumber.
@TheArchenoha Thanks. It's nice to see that this one didn't get blocked in Germany!
@teenprepper96 It's supposed to be around $15K, but will end up being around $20K
I say again.. you're the man. You put a lot of time and effort into this project. I hope this dome treats you well and lasts for the rest of your life. Major props to you man
Should have grouted everything solid. Water will get in the block cells.
I would have just left the "basement" space open, and not filled it with dirt. What was the point of that?
IN HIND SIGHT, I WOULD HAVE WRAPPED CARDBOARD LAYERS AND A BIDT OF PLASTIC AROUND THE TANK, RATHER THAN GET THE BOARDS DIRTY!
why wouldn't you draw hotter air from on top of the dome and heat the ground.
It's called a climate battery. Google is your friend.
Good to see the progress. I got my geodesic dome fix. Good quandary/problem solving music. Finding these missteps now will make the second dome go up that much faster :) You should really wear steel toed sandals on a job site.
@TheLegalgrow Budget=$20K, Actual=$30K ;-)
32.5 feet across
Good stuff. Thank you for posting these. I'm curious why you laid all that dirt before laying the ducts. Wouldn't having the ducts deeper in the ground help regulate the temp of your thermal mass? Are you concerned with stagnant moisture in the ducts (e.g. fungus, Legionnaires' disease)? Also, how did you determine the length of ducts? Are then long enough for a greenhouse that size? Not trying to pick but i'd kicking around similar ideas and am genuinely curious.
I did. It's in video #6
by far best set of instructionals i have seen. You did a fantastic job on designing and constructing. And a far better job presenting it. Thanks. Curious tho of the budget for the project?
Will the pipes be carrying the exhaust from the rocket stove from your other video? If so will there be a problem venting the waste gasses into the green house directly?
ants/termites
@web4deb WOW hope its woth it for you, are you going to keep your small system? and are going to stay with goldfish
@web4deb if all the people who watch your videos donated a buck, you'd be able to cover the over-budget, and more! :-)
Your the man, I hope one day I will be able to tackle a job like this. What is your back ground?
Love the suspenseful music during the "nervous" part of the video.
@web4deb Eek! I assume you have some kind of business plan you're working toward with this.
Looking good! So you're only using one layer for the SHCS or did I miss a layer or 2?
No insulation under the thermal mass?
one layer
@web4deb
In Germany they only block videos with Sony music copy rights ;)
Did you know that you should put something between brikcs and wood, at 06:40. Something like roofing felt. Because if you don't do it, the wood will moulder. and the situation like you, it's a very big job to change those woods. the humidity likes to rise along the bricks, and if there is something waterproof, all boards will stay good.
PS. sorry for my bad english. I am from Finland
great job, cant wait to take things up a level to your scale! check out the green diamond aeroponics system
I hope you don't live in a windy area. Locally we put at least two rebar rings in the foundation and tie vertical rebar every 12 ft. to the footer rebar, then those go up thru the block openings to the top where the anchor bolts are tied to the rebar and the entire column filled with concrete, finally the sill boards are fastened down with nuts Your dome seems to only be tied to one block every once in a while and cement is not strong as it cannot be squeezed but is easy to pull apart...
Very exciting. Great job. The part about the tank fitting perfectly had me cracking up. Gave you a thumbs up.
Amazing job so far. I would like to put an SHCS in mine too. I'm still hunting for how-to links. Are you planning on using solar panels or maybe solar evacuated heater tubes.
any concern about mold or bacteria in the perforated piping for your ground to air HVAC system?
it has always been a concern because the ground is so damp, but it hasn't been a problem. thankfully!

they custom and pre-build very efficient green houses. I like their ground source heat and cool system below the green house space. let me know what you think and see if they have mistaken your project as public or not? I hope you have determined new applications for your space as the tragedy becomes opportunity.
watching your videos makes me not feel so bad for all the mistakes I made in my AP project, which was considerably smaller than yours and what I thought had been well planned at each mistake.
With a soupier concrete mix you could have left the J bolts in the plank and staple the foam/barrier material on the bottom of the plank. Just set the plank in and wriggle it a bit.
Done. Make sure block hole taper is in correct orientation. Narrow at the top.
I love your problem solving ideas re both tanks! OUTSTANDING Vids! Hope you're keeping track of your time and materials so others (me) can get an idea of how much work it would be!!!
Nice work. How is the heat transfer system working with the tubing? Are you using it for cooling as well as heating? I'm doing something similar (just broke ground) except I have one circuit 2' deep and am using 2' of gravel around the tubing as the thermal mass and also have another tubing circuit 5' deep to take advantage of the consistent 55 - 60 degree ground temperature for heating and cooling. That way if I need cooling and the gravel/mass is too warm, I can blow the hot air down into the 5' deep circuit.
I mainly use it over the winter when I don't feel like running the heater over night. We've had several nights where it would get down to 0F and The lowest the greenhouse got was 41F. I haven't used it over the summer since it doesn't really get hot enough to need it.
Did you consider steel construction, especially the knee wall instead of cedar? Would have it been cheaper?
What grade/quality is needed for ground piping to avoid it crushing under rock, sand, and pavers?
You are a saint! When the barrel got stuck I would have smashed it with the loader then taken a vacation
thanks! we are thinking to built a dome for me, i love plants and id love to have a 40'. but im afraid itll be too dear.
You are awesome! Incredible thought and vision! This thing is going to rock. Great job. I can't wait to see more.
Rockon!
What size tank is that you used for fish storage? Do you wish you had gone larger or smaller? thanks
Man, I wanna see this dome badly!!!!....Excellent work with these videos too, entertaining and informative!
I'd call that smart business... $30,000 vs. $100,000+ adds up (to me) to intelligent farming.
My God the music. Why
nuts them last few have been gemmaed in germany :(
the best video project diary on youtube! Can't wait for the next installment
In true old guy form.... Sweet!!
How much has this project cost you
Great attention to details...and a lot of details! it's looking good.
How big should a sump tank be?
franchement ce que ce monsieur a fait c est bien pour lui mais en france ilya des normes que l on doit respecter et je ne crois pas que les entreprises du btp francais acceptent cela ceci est un projet concretise pour lui meme bravo mais ilya des choses a revoir respectueusement votre
Keep up the good work. Patiently waiting to see it complete.
i love the way you do this wif passion.. thanks 4 the share
Amazing job. You rocks the dome. Greetings from Germany
This should be on Netflix...
are you an engineer?
Amazing videos - you are very clever.
Hello and I love your work, been following since the beginning! I have recently built two greenhouses and have buried eight 100 foot long tubes for the thermal mass. I hooked them up and don't have any air flow. What CFM calculation did you use to size your fan and are you pushing or pulling the air? Thanks in advance!
You'll need a pretty large fan to push air through tubes that long. I'm using one of these to push the air through. It's still wasn't enough. There's just a huge amount of resistance from the corrugated piping. I've basically have giving up with the geothermal mass. The biggest problem is that water condenses in the piping, molds, then blows the mold into the greenhouse. Once I stopped using it, most of my disease problems with the pants have stopped.
www.northerntool.com/shop/tools/product_200660314_200660314
It's perforated pipe so the condensate can drain out. I just keep the vents open and it will be around 10 degrees hotter in the greenhouse. When it gets really hot out I open the doors too.
love these updates. Keep up the good work w4d.
awesome vid
The icing on the cake is almost here! :)
tks 4 the post ....looks awsome so far !
How many tons of gravel did it take to get your 6" in the dome?
I don't remember. I sure it was a couple of truckloads. ;-)
Nice
Nice
Great job pal. You inspire, truly!
Awesome to see your progress!
first! i love you
love the geese
