I have a polycarbonate roof as well, and bought the same Remington fan. Your journey with this was good inspiration for me in terms of how to adapt the attic fan for greenhouse use. Mounting it near the ridge and using flashing was clever. My greenhouse is a sloped roof but not ridged, so a waterproof installation of the fan has been more difficult (this thing was clearly designed for shingled roofs). Thanks for sharing.

[@SettlerLife]

Greetings from Ukraine! Nice project! My parents had such a greenhouse for 18 years! It was a greenhouse for vegetable seedlings.

[@RainCountryHomestead]

Nice work and attention to detail.

[@homesteadonomics]

Thanks RCH! Joe

[@stoneybakermd1936]

this fellow is humble. hes a journeyman carpenter no dout. got awesome calves, lol great vid. thanks

[@amberteeters1]

love the fan and adjustable swinging door....side not...just noticed your shirt lol....can wait to see the watering system!!

[@homesteadonomics]

Thanks Amber! btw... what did you notice about the shirt...my fancy inside out usage;) hahaha... I like to keep a plain look on the vids and the inside out shirt works great;)

[@amberteeters1]

i was watching and i thought..."that pocket looks strange" then it dawned on me lol...really love watching this project come along....i do have a question though.....how do you have the green house facing...is it more important to face it so the sun follows the roof line or so the sun travels across the roof line....

[@tomsikes9064]

A series is what is organically no pun...called foe. And very helpful to those of us who have never done such a thing. Thanks!

[@JohnnyPeacenic]

that is the correct way of building a greenhouse below ground. i will tune in again when you plant the plants.

[@jbhann]

This whole greenhouse series has been great and you've done an amazing job Joe.

[@homesteadonomics]

Thanks JB! It's been a fun (but tiring;) project and I'm looking forward to actually growing stuff in it this fall! Part 6 should be in a couple (2-4 weeks)... currently digging the cooling tunnel:) Joe

[@cokeman250]

Man Joe this green house is great. Thanks for Sharing it with us God bless buddy

[@homesteadonomics]

Thanks so much CM! God bless you too!

[@rwhite4688]

Today is the first time I’ve seen any of your homesteadonomics videos on KZbin. I’m a fan. I subscribed after the first one I saw on your rainwater capture system. Perhaps THE BEST teaching & sharing vids of practical, thoughtful information on greenhouse design and build and rainwater capture I’ve seen yet. You show economy and creativity in materials you choose. Like your gutters. Even your explanation or description of how what and why uses an economy of words. Love how you break down these projects into a series of short videos - useful, digestible chunks. Smart. Your honest, simple, cost-to-build (including labor, materials, PVC pipe and tanks) for your rainwater capture system is such valuable information to know. Thanks for sharing that! So good. Love this project! You created, built this aesthetically-pleasing, thoughtfully-designed, practical sunken greenhouse. Looks sharp, clean! Your projects retain or enhance your property’s natural beauty and value. Most of us would use unpainted scrap wood or a mix of new and scrap lexan panels maybe even of various colors or fiberglass. You didn’t. Looks like you built your greenhouse to last, be usable and it looks good too. Just guessing that since you said your wife helped you build it... that she likes its looks, too. And that’s always a smart move. Your vids are a phenomenal resource to any DIY’er. I find them truly inspiring, too. I’m a fan! Thank you, thank you!

[@curtisscott9251]

Add a multi-head water mister line inside near the air intake window several meters along the peak, & modulate the water flow with an E-valve controlled by the activation of the solar vent fan. When the roof vent comes on - the water should flow to the misters & the temperature drop inside the greenhouse should be rapid as that mist phase changes.

[@pinemeadowshobbyfarmafruga8319]

You sure put a lot of thought into your greenhouse project. Thanks for the series.

[@homesteadonomics]

Thanks so much! yes, it has been a fun project... didn't grow in it as much as I wanted to this winter but looking to be full force this coming fall:) joe

[@350pauli]

Luv the wind idea

[@blackberryhideout5793]

I enjoyed the math and science of this video!

[@homesteadonomics]

here's my math....60% of the time, it works every time;)

[@homesteadonomics]

btw... we doing breakfast this coming week?

Awesome project

[@homesteadonomics]

Thanks SNRF!

[@DeepSouthHomestead]

Been looking at solar fans myself thanks for the idea on a fan.

[@homesteadonomics]

Thanks guys! Might be a good addition to yours as well:) Joe

[@happyneek4699]

Very nice greenhouse!

[@homesteadonomics]

Thanks so much Diane! I've got a bit more to do on it but it should be grow read by this Oct/November:) joe

[@melissawillis6822]

I have been extensively researchIng greenhouses and THIS! You have done an amazing job! This would be my dream greenhouse for growing all year long!

[@akamjo1]

Thank you for the excellent and innovative

[@ConscientiousOmnivore]

I like the idea of the door... totally passive and practical!

[@martiebaby]

What I really love is that you consider both function and beauty when building this project. What an amazing job you have done. Really love it.

[@homesteadonomics]

Thanks for watching the series Martiebaby! ... and for all the very nice comments too :) This has been a project that has been in my mind for sometime and I'm excited to actually be on the verge of using it:)

[@vicsuper8410]

Beautiful greenhouse, can't wait to see when completely finished.

[@homesteadonomics]

Thanks Vic! Me too... soon! just did part 6 and part 7 should be up in about 3 weeks or so:)

[@CharlieCiampa]

So awesome I couldn't sleep last night, the smourning i showed my hubby and he remembered me showing him your videos thank you this is so close to what we want to do

[@joom2087]

Very nice job !

[@homesteadonomics]

thanks!

[@andreajohnsMyPotteryBliss]

My aunt ran a greenhouse in Pasco, Wa (high desert). She didn't grow in summer, she just closed everything up tight and used the high heat to kill any pathogens or bugs that established themselves during the growing season. She never had to spray for anything.

[@murrrriel]

That's really smart!

[@joshuasabatino6128]

self sufficient living is so rewarding (i think) im 17 and wanting to become a civil engineer! i think im going to live dirt cheap and save up alot of money and then buy a property and invest in self sustaining living things like the water tanks and a workshop. I love chicken so much! do you think i can raise chickens and eat them? and grow my own feed?

[@moysfree6660]

the trick to growing plants in hotter weather is to keep the soil cool I have greenhouse and it gets up to 125 in the summer even with ventilation but when you stick your finger into the soil it's nice and cool which keeps the plant cool. one way to do this is to cover the soil with mulch or straw. and if you want to keep the soil warm you put black gardening plastic over the soil which you can cover later in the warmer season with mulch or straw that way you control the temp of the soil.

[@stormytrails]

Never ever resort to plastic over the soil. To kill weeds and solarize the soil and cook the weeds you use CLEAR plastic, not black. Not white, not black but clear. Honest. Raised beds with organic matter do just fine for heating up during the early spring and staying warm during the fall. Plastic is always wrong. Landscape fabric was only made to stop the coarse gravel from going down into the soil profile while the fines percolated up to the surface. This weed stuff is a bald faced lie to sell more landscape fabric. Covering the surface with straw or chips or non decomposed organic matter means you need to add extra nitrogen to feed the decomposers doing the work of decomposing. Only DECOMPOSED organic matter can be eaten by all the other soil life. The soil life goes dormant or dies until that layer of bark or straw is decomposed. The added extra nitrogen needs to be added to the math with the balanced fertilizer you have to add to any soil for plants. No soil comes with the proper chemistry for plants to do photosynthesis. It isn't plant 'food' but proper chemistry for plants to make their own food via photosynthesis. Never stop what little 'environmental cycle' you've got with your soil and plants by putting 'weed fabric' or plastic down for mulch. Plastic, bark, rock, wooden or concrete sides make great condos for housing insects, slugs, snails, varmits, pill bugs, earwigs....not good. Soil life helps control non-beneficials as well as playing an important part in the uptake of chemicals ('nutrients') by the plants, keeps air in your soil (aeration) and do all the work for you mixing organic material within the top 8" of soil. Just put a couple of inches of decomposed mulch on top of the soil and the soil life comes up to eat it. Goes back down into the soil profile to poop it out mixing perfect organic matter into the soil for you. I double dig my beds once, add trenches at the base (in or out of a greenhouse) and I know enough to never have to use pesticides. Licensed for 3 decades as commercial pesticide applicator which means one is taught basics to never have to ever use pesticides (herbicides, miticides, fungicides, etc....killing of life forms that should never have been allowed to get out of control so pesticide application is like a band aid on a problem that should not have been). So a little TMI. I apologize! Grins!

[@kennapop3]

Old school green house tricks included paint water, based that wore off. I worked at agreenhouse in Illinois that had roses that required lower summer temps lots of fans and open doors ect . The late spring paint lasted through mid August and could be washed off if needed.

[@homesteadonomics]

Wow! that's actually a pretty ingenius idea... lasts until it's not needed... then some more the next year:) thanks for checking it out KP! Joe

[@GaryHardin]

At 4:05 genius also 6:31 the entire greenhouse is amazing, love this. I want one.

Thanks so much Susie! joe

[@jeffsullivan3362]

I saw your greenhouse on the Tuftex website. Impressive.

[@homesteadonomics]

Thanks Jeff! It's been a fun project that I've probably spent way too much time on... especially for not having grown anything in it yet...lol! thanks for watching:) Joe

[@TheCueUpBlog]

Super exciting to see it getting closer and closer to the end ! Can't wait for the next update !!!

[@homesteadonomics]

Thanks TCU! currently digging the cooling tunnel now:)

[@krzmal12718235]

Love it. After that I started to fink it is possible for me too. My foil tunnel was destroyed by wind and that looks like a much of a better solution than standing green house.

[@charljoubert6993]

Awesome, really looking good, now fill up the greenhouse :). I am harvesting about 2 pounds of tomatoes a week from two plants I keep in the greenhouse.

[@homesteadonomics]

Thanks Charl! I probably won't be putting in there until October. My plan is to use it from Oct to April... or there abouts. Awesome that you are getting 2lbs a week from two plants too! And this is your winter... very cool! Makes me excited about our winter:) joe

[@alaskanhunter7622]

You should add a thermal mass cooling vent. If your not familiar with them, look up a Earthship, Earthships use thermal mass cooling vents to cool an entire house without any electricity.

[@homesteadonomics]

That's kind of what I'm looking into... check out part 6 and I talk a bit about a cooling tunnel I'm working on:) Joe

[@uktony1525]

"The grass always looks greener on the other side of the fence", here in the UK we are having a very poor summer and we dream of needing a solar fan. A new income stream could be offering holidays to Europeans to lie and sunbathe in the greenhouse :-). Great video as always and even though we have the opposite problems it is a real treat to watch the greenhouse become a central part of the homestead.

[@homesteadonomics]

yes! it is so true... I'm over hear longing for your cool moist air and you guys are probably thinking some warm dry air would be nice. If we could just figure out how to go 50/50 on our climates;) Actually as an income stream, I think I'm going to use it to start a ton of seedlings to sell next spring. Sunken Greenhouse Nursery;) And Tony, you are welcome to come over and sunbathe in the greenhouse anytime:) Joe

[@stevendgrissom1968]

keep going bubba. still would like to se you make a pond for aquaponic system. maybe you can use the rain collection system supply pond and green house. a true use of nature.

[@homesteadonomics]

Thanks Steven... yes, I plan on trying to incorporate the rainwater collection in the greenhouse too... but just figuring it out right now, so it's still in the planning phases:)

[@jayejaycurry5485]

There is one thing I would call your attention to. Greenhouses get almost no light from the north. So, it would be beneficial to replace the glazing on the north side with insulated material in colder climates. That being said, your greenhouse is so very impressive. The design looks great. The construction looks better than I've seen other people do. And, it is readily apparent that you have put a lot of thought into what you were doing. I can only aspire to what you have accomplished.

[@homesteadonomics]

Thanks Jay! It's definitely a work in progress...haha... and has kinda taken on a life of its own. Ended up being much more involved that I had anticipated. But it's been fun and I can't wait to grow something in it this fall:) Joe

[@jayejaycurry5485]

Yes, Dr. Frankenstein, I can see how the "monster" got away from you. But, perhaps that is a good thing. I've learned a lot watching. I am wondering if you are going to build a bigger brother next year, perhaps with a climate battery.

[@RobinLewisMakes]

That solar fan is an excellent idea!

[@homesteadonomics]

Thanks Robin! So far so good... it doesn't create a torrent of air but it hums along nice and smooth and pretty darn quite too. I'm thinking that come fall, it's gonna be ready to go for some planting... i hope... it's been way to big of a project to not be growing quite a bit of stuff this winter:) ... gotta reap some rewards!

[@RobinLewisMakes]

Yeah, it feels like it's been going on for ages! It'll be goo to see it "in action"

[@UTubeGlennAR]

Great project, TY 4 sharing..... Hope the last thing U do is add some good soil a plants..........

[@homesteadonomics]

Glad you're liking it Glenn! ... and yes, I will have to add some plants in it for sure... so far the only think this has grown is itself...lol.... I'm planning on trying to grow in it from Oct - Early April... and then probably let it be empty during our hottest months Late May- Early Sept.

[@JRCHomesteadTexas]

I like that fan for the greenhouse, it might also help to keep a coop cooler.

[@homesteadonomics]

Thanks! I think it would certainly be useful on a coop as well:) Joe

[@chevy6299]

You must do all your work when the sun goes down. WoW a 105 temp at noon !!!

[@homesteadonomics]

haha... it's been hot but that 105 was just from the thermostat being in direct sun for the 20 min or so. It was actually about 100 during the whole test and I think the hottest it was on that day was 102 or something like that.

[@chevy6299]

God bless you Joe as I think 80 is hot but 70 seams cool.

[@BubbaStump37]

cooling tunnel 3" pvc with ground rods poking through. they will conduct earths 55 degree and the exhaust fan will draw air in through it

[@Ferelmakina]

good work, man

[@homesteadonomics]

thanks Fernando! Joe

[@yackfzay6224]

Building a greenhouse, there are so many steps to keeping it functions. You might put a solar-powered just for a fan to distribute air flow. Keeping it cool in Arizona. In Washington state we have to keep it warms with fans to distribute heat.

[@homesteadonomics]

yes, it's going to be a bit of experimentation to see what works here. I plan to put it into use by Oct and use it through April or so. So hopefully I won't have to worry about venting off the super extreme heat that I showed in this test:) Joe

[@Canadiansasquatchbrewery]

Great stuff Joe. The hot house, is hot! (= It would be good for some tropical plants, and hot peppers like the heat too. I know my ghost chilies quite like it the hotter the temps are. May need to be wary of the other things that like the heat, mold, mildew, etc. As always awesome video! Cheers!

[@homesteadonomics]

Thanks! and yes it is! HOT!!! I don't think the mold or mildew will be a problem... but I'll have to keep an eye out for it for sure. If so I think the GH can be dried rather quickly with everything open.... and you can bet there will be peppers in there this winter:)

[@ragtie6177]

always look forward to your updates! great video thanks for sharing this with us it's coming along fantastic!

[@homesteadonomics]

[@autiemuse]

This greenhouse series is great! How about shade cloth used in the interior roof? You could suspend tent window-style roll-up shades with ties or utilize a shade cloth with suspended wire system used for pergolas. I think that shade cloth would mitigate high-temps by at least 20 degrees before ventilation system kicks in. Thanks again for the great series. I subscribed and liked in response to your excellent and informative videos!

[@homesteadonomics]

Thanks! I've got some thoughts on the shade cloth but haven't figured a definite solution yet.... but I've got some ideas:) btw... thanks for the sub and I'm glad to have you along for my random projects and other activities Autiemsue:) joe

[@NilsAlbertsson]

The solar fan's a great Idea, but tou should've put it on the north side, and thus save every square inch of south facing roofing available for light ingress.

[@TwilightMysts]

Really cool greenhouse you have there. Just a few things I probably would have done differently. First, before digging out the pit for the greenhouse, but after marking it all out, I would rent a Ditchwitch or some such and dig 2 sets of trenches (one on each side). These would be used for the heating/cooling tubes. Second, I would have probably made the actual greenhouse a little bit shallower, but dug out more dirt on the inside. There would be more total dirt to move, but I would have piled that up to add more depth to the thermal mass for the 2 heating/cooling tubes. Third, I would put a small extension off the back, into the berm behind the greenhouse. This could be used as an airlock for getting in during the cold season for less heat loss while entering/exiting. It would also function as a small storage area inside the greenhouse that would not interfere with the growing space. And third, it would contain the control equipment for the temperature control system. Which brings me to #4, the Temperature Control system. By having 2 different sunken loops, pretty much, you have one side where you store heat, and the other where you store cold. During the summer you pull from the cold cool the greenhouse while building the heat storage. During the fall you pull from the heat storage to warm the greenhouse while building the cold storage. And all it takes to heat/cool the greenhouse is a couple of fans and a fancy valve system to control the air flow.

[@nateypecks]

That's exactly what I've been thinking - thermal syphon with the fan to assist. probably prohibitively expensive for what he's got going on though. Sinking it in the ground was a great idea. The effect of the sun/lack of sun on the temperature of the earth's crust is halved every three feet so to get to the stable 55 degrees we need to have a trench that's 12-15 feet deep depending on where you live and how hot/cold it gets during the day/night. If all we want to do is cool the air from 110F to 80 or so the trench could be 6 feet deep and would work well - then it's just a question of how long the run needs to be.

[@homesteadonomics]

Wow! those are awesome ideas guys! I'm currently digging my trenches and trying to figure out the rest of my game plan but i love what direction your headed! Unfortunately, some of the things are a little bit beyond my capapbilities right now, at this stage of the project. But that's exactly the thinking I love hearing regarding the cooling/heating and the thermal exchange. Anyways, if I don't address all of these things in the next part, I'll probably try to address them in the GH questions and answers video later this winter:) joe

[@shaneoconnell5150]

If you added say a 2 block tall knee wall you could easily add a gutter system.

Idea for water harvesting from your green house. Some how collect the water at little below ground level. in a bucket or container have a water pump with a floater so that when it reaches a certain level of water to activate the pump and pump it up to a 50 gallon drum or container of your choice. just a thought, great build by the way. Cheers.

[@robertklinkhammer9269]

I plan on building an in ground greenhouse, but I don't think I can put as much money as you did into yours. I hope to build one 20'x12' but in order to not be taxed on this I will not use any cement. Hope to use drums with salt water in them for a heat sink for the winter in Wisconsin. You really built a great weather proof greenhouse. Nice job. I know I am not as talented as you at building. But seeing all your videos I plan on trying my hand at it. Thanks.

[@homesteadonomics]

Thanks so much Robert:) I like your idea too! That's what I kind of originally planned (I told my wife it would cost about 250bucks....lol.. ouch I underestimated a bit;) I was going to do a sloped hole and mount the structure to uncemented cinderblocks set on the ground, and use old windows or plastic... but then I started getting carried away:) I like your salt water idea too... very smart for your winters! As for taxation... I've chosen not to have water plumbing or electric in the GH and keep it under 6' foot in total height to keep from that was well. I guess only time will tell, depending on if someone(assr dept) sees an aerial shot, etc,. but I guess I'll come to that when it comes:) joe

[@leeannmaul9938]

Really enjoyed your series! I am currently drawing up plans for a full UNDERGROUND greenhouse, complete with aquaponics. U have given me a lot of ideas. I do have a suggestion for u, tho. The tunnel u are digging for more ventilation? Consider that tight squared hardware cloth at each end. One mouse, or another rodent of any kind, cud decimate your crop(s). Pest control will be very important. Also, how do u keep the rain from pooling at the steps? Since i am doing a larger-scaled, and deeper, greenhouse, i considered a staircase just on the interior...along the side of one of the walls, or near the wall, building the door right into the end of the greenhouse wall. I cud also do one of the support beams ther to the roof along the other side of the railing. Hmm.. wheels are turning again. Back to the plans..lol. thanks so much for yur ideas, and insight. Best of luck!

[@jerryyeh2251]

I am in Puna District of Hawaii Big Island. Need a roof that will block the rain but let sunlight in. Does your roof let in all sunlight except UV? Is it a polycarbonate sheets? Where did you get it?

[@rankenhunt]

where did you get the tool for driving the rebar/H-posts, the H-posts are cool also I guess I could make the but time is not my friend. Your design is great I just need to modify for 4'frost depth and volcanic ash for ground requires lots of support. Thanks for sharing.

[@homesteadonomics]

I borrowed the jack hammer from my father in law and the driver attachment I had to rent from Sutter Equip. Yes, a 4 ft frost depth would definitely need some changes but hopefully this might give you some ideas:) JOe

[@Seyahremraf]

What is the humidity like where you are? Have you thought of doing a swamp cooler?

[@homesteadonomics]

We are in a really dry climate so a swamp cooler would work really well. I've thought about it but will need to modify an opening. But it may be worth doing as we just hit temps that will put the green house out of use until Sept or Oct. Thanks for checking out the videos:) joe

[@CharlieCiampa]

Really your thinking of swap cooler, I wonder how you could do all this with wind power generated

[@dansuich]

Do you have PV on your home? Why or why not? How do you get your electricity?

Awesome greenhouse, you did an amazing job. What made you decide to built it in the ground the way you did? Thanks Sharon

[@homesteadonomics]

Thanks Sharon! I'm planning a GH Q&A video soon to, to answer those questions. but the short answer is to take advantage of the thermal qualities during the winter, keep it low in our hi winds, and because it seemed like a cool idea to try:) Joe

Thanks so much! Joe

[@ChrisSwain2020]

This greenhouse is awesome! I want one! How are other greenhouses in the desert designed so the plant don't get scorched in the summer? For your water harvesting from the greenhouse roof you could consider putting a french drain system along the walls where the drip line is located and funnel the water in the french drain pipes to your rainwater harvesting system. I put in a similar system around my house to capture the rainwater in my in-ground gutter system and funnel it to some swales where I plan to plant fruit trees. It looks rather nice with the gravel bordering the house and I don't have to worry about gutter maintenance or potential stucco mold issues.

[@homesteadonomics]

Hi Chris, Most of the other greenhouses that I've seen here are pretty traditional above ground structures. And like myself... most folks don't do much if any gardening inside the greenhouse during the summer here. I plan on it being more of a fall, winter, early spring kinda thing. Regarding your drain system... I like that idea a lot! Very useful and I may have to consider somethign along those lines. Currently I'm planning a 'drain tray that extends over most of the shelf growing areas that will collect all of the drip water from watering the plants and drain it into a bucket... to be reused as a compost tea of sorts:) ...but with that said... I gotta figure out my main raincatch first....lol... I'm trying to figure something that will be lower than the gutters but with a bottom still higher that the plants so I can use a hose to water the plants. ... but that's all just ideas now... gotta get working on it for my brain to figure the solution:) Joe

Looking great! I wonder if there is any way to harness the cooling aspect of harvested rain water with the harvested "cooled" geothermal air you have in that tunnel you pointed out. For instance, wrapping hoses around the vent pipe. I don't know, but this whole thing is just darn cool, actually "hot" cause it's a hot house. It has been great watching you develop this thing as you go; like Indiana Jones says, "I'm making this up as I go." :)

Thanks Tim! I actually started digging the tunnel yesterday. Not exactly sure how it's gonna go but I guess I'll have to figure it out when the trench is dug. I do wonder if it will make a difference (the tunnel)... but I feel like I won't know unless I try it;) But even if it doesn't work, I'll atleast have another ventilation option. I like the idea of using the rainwater to give a evaporative cooling affect inside the trench. Not sure how I'm going to do it... but as you said, I'll have to "make it up as I go" :D

A QUALITY build !

[@homesteadonomics]

thanks free saxon!

[@funtimes_1111]

awesome greenhouse!

[@homesteadonomics]

Thanks so much Liliana! Joe

I wanted to ask you, do you have some animals domestic or wild, i know about chikens, but they are in theirs coop but some animals that are freealy walking in your place? And if you have, are you going to place some safety mesurmetnts for your plants to not get eaten by some animals(or people). :) Like some screen door or something like that?

[@homesteadonomics]

We just have chickens right now... and they are able to walk most places on the property when we let them out in the morning. Our garden has a fence around it as the chickens would damage the plants pretty quickly. They other plants (non veggies) don't seem to be too affected by chickens pecking at them. anyways, not sure if that answered your question completely or not. We do plan on doing other animals in the future but I gotta get some other things accomplished first:) Joe

Really great videos man, thank you for taking the time to bring them to us! Just waiting on 6 now haha :)

[@homesteadonomics]

Thanks Matt, I appreciate it sir! Part 6 is currently in the digging phase...lol... and you can see the pipe for the cooling tunnel laying in the background of one of the night time shots of the 'flashlights' video:) kind of a sneak peek :)

[@thecircusb0y1]

critters get in through that wind vent?

[@JayDeeBerryman]

This turned out great! I am from Tucson too, are you down south of town?

[@homesteadonomics]

Thanks Jay Dee! Yep, I'm west of Sahuarita:) Joe

[@JayDeeBerryman]

Awesome, I think I found your youtube through Survival Podcast searching for Arizona homesteads heh. I am living in town but looking for land outside of town from Rio Rico to Marana and anywhere else I can find. Love the fact you are using almost all rainwater for your home, that's impressive!

[@sherrymorales8230]

dig a trench big enough for a regular house ac vent its rectangular like the hole in the block then you bury the vent after you fit it in the cutout spray the seam with flex seal to guarantee a proper fit

[@chinazoanyaeche443]

how much is the solar fan and where can I get it

[@rennells]

I was hoping the temp would be cooler. Love the idea

[@JohnGuest45]

I`d recommend using multiple shorter tubes for the cooling tubes. You`ll get more airflow and all of the tube surface area will be working for you. With a single long tube, the air will cool to ground temperature long before it reaches the greenhouse, especially if the air is humid ;)

[@homesteadonomics]

Thanks John... you'll see in the update that my plan for the cooling tubes didn't quite come out like I hoped but I'm leaving an option for a later upgrade. Part 6 should be out in a couple weeks or so:) joe

[@RobertSeviour1]

This is s very nice project, thanks for the video. An idea for cooling you might want to examine is a Trombe wall. In effect that is what you will be creating when you finish the subterranean cooling tunnel

[@homesteadonomics]

Thanks Robert! Yes, that is something I'm thinking about in combination with the tunnel. One of my subs from S Africa has something like that set up in his GH and he says it works really well:) joe
