Another option is to vent your clothes dryer into it. If you don’t want all of the humidity just running 3 or 4” pvc pipe through the greenhouse and taking advantage of the heat exchange and let humidity vent outside.

A suggestion: the air gap which you mentioned in your discussion of the frames covered in plastic can be easily doubled by wrapping the frame rather than covering a single face. I used to make such frames for use in the windows of my home. I made the frame 1/2" thick, wrapped it in plastic, then applied 1/4" on both faces the same width as the 1/2" used in the frame. The 1/4" material kept wind from tearing the plastic. I built these frames to fit snugly within the outside moldings of my windows and held them in place with small wedges. The double air gap made a huge difference in my heating bills.

[@jasonjayalap]

Thank you. But, can you clarify this line "then applied 1/4" on both faces the same width as the 1/2" used in the frame"? 1/4 of what material to the wrapped frames?

I don't know if you will ever need Styrofoam again. If you do need it you can get free hot tub tops. Once you take the cloth off you have a large thick piece of Styrofoam. It can easily be cut with a serrated knife. We used it to insulate around the skirt part of our cabin. If the hot tub cover is water logged, it will dry out if you let it sit a while.

[@SpYucaipaSoCal]

I think using the underground heat and cooling like a battery is the best bang for your buck. I have seen water storage tanks at a university used for this purpose. Use a thermostat set to your liking parameters. To run a fan similar to one in video maybe a solar powered charger that charges a battery during the day and drains for the nighttime operation. Heating the ground underneath I would fill with course rock or cinder blocks for the thermal mass and air flow during the day. Intake on one side and exhaust on opposite side. My goal would be to keep above 40 degrees at night and knock down the daytime temperatures with automatic roof panels and possibly another solar fan. All in all that’s a hell of a setup you have there but my idea would be to more doable for the average gardener on a lesser budget. ❤

In four years, temp has never dropped below 42 even when negative 8 outside. For cooling, I use a fan high on one wall that kicks on automatically and opens two intakes that are on the opposite wall. I can't cool below outside temperature. If I ever build another one I will use GAT system for both heating and cooling.

[@jennablorezone8Band9A]

Wow that’s a serious greenhouse!

[@MartinVDam]

Helpful tips! I have one comment about adding the extra plastic foil on the outside of the windows. Obviously this adds tremendously to the insulation of the greenhouse, but it also reduces incoming radiation which you need to collect heat. Even more important, some plants need direct sunlight to grow optimally like peppers tomatoes and so on. So adding more 'transparent' layers like this can limit the growth of certain species you want to grow in your greenhouse. I mean you probably can grow sun loving plants but in greenhouses it's all about optimizing and controlling these factors. This is something you should take in consideration when setting up your greenhouse.

[@WineberryHill]

For the most part peppers and tomatoes or something that I grow in the summer months and therefore I don’t have insulation on the windows.

[@hawklord100]

I saw a guy grow strawberries on Chrismas day, all he did was take his 'Poly tunnel' and set up another smaller Poly tunnel inside there was about a 4ft gap between the poly tunnel plastic walls. There was no heating just straw covering the floor inside the inside poly tunnel. By the way, the colour black... radiates more heat than any other color and this is why it feels warm to the touch.

[@bradley200711]

you can attach clear bubble wrap to the inside windows during the cold months too.

[@alexandraderry7086]

[@balkangetaway]

I have a stone wall, double glass windows and a woodburner for the coldest days. I can heat a lot for the price of what insulation, plastic and water storage heating would cost me.

[@GMC-qo9xi]

Water storage heating is theoretically free. Plastic containers are constantly being thrown out-like say the typical 5 gallon style stackable pails (19l)... maybe they need some black paint, but often that too can be found for very few dollars/euros/etc...

[@loudidier3891]

@@GMC-qo9xi I paid $8 each for 55 gal drums like the blue one in the video four years ago. Online they are expensive but a recycling center/junk dealer only five miles away had a huge stack of them. One can of black flat spray paint for the side towards the sun does three barrels.

[@TheFredmac]

An IBC tote or even a dump trailer with wood chips. Insulate appropriately, coil of pipe, heat transfer fluid and you have a renewable heat source. I suggest wood chips because they are easier to get out of the container when it's time to change out the biomass.

[@WineberryHill]

Great idea!

[@jeremiahr7585]

You can also keep a compost pile inside or next to the green house to add heat.

[@WineberryHill]

I actually built the greenhouse with this in mind. I put composting set up (video here: kzbin.info/www/bejne/g3KshmaZhq52frs ) right next to the greenhouse for this very reason. I also plumbed pex tubing during construction out to the bin area. However, I never ended up needing anymore temperature boost than what I got from the other methods. So I haven't completed that aspect.

Sweet greenhouse. I really like the drop ceiling-- super basic and effective way to conserve heat! Also, the foyer seems like a great idea given how many other heating systems you have going on.

Lots of great information. Thank you for sharing. One question: why not paint the exterior shingles on the house black also?

[@WineberryHill]

Maybe if we were in zone 2 or 3, but the summer in 6b is pretty hot and the greenhouse would be an oven. It’s tricky finding a good balance.

[@m.griffith2059]

The siding. Its pallets. Can you tell us how you did that? It looks very tight, as in close together. Does water get behind them? Did you put them up like Shingles? Thanks Nancy.

[@GMC-qo9xi]

What you see is what you get. Meaning they look like shingles, because they are cut in roughly the same length/shape as a typical shingle... and installed like a typical shingle. Only difference being that they are not tapered/wedge shaped... but that doesn’t matter. They shed water the same way, by overlapping each other. BUT you must put at least tar paper behind them... So in his configuration, he has plywood behind them, and then presumably a building paper, but probably just tar paper for cost factor... so depending how perfect you want it to be, like say it’s part of your house, then in that case you could put a building paper over the plywood, like Tyvek, then you could put horizontal strapping underneath the shingle where you’d be nailing them, etc... BUT in this kind of construction, which is done with cost and ease in mind, you just put tar paper on the wall and then start shingling row by row, starting from the bottom... and if you want more security from rain, like really wet place, then as you go up to the next row, you place a narrow strip of tar paper between each row... so the part of the row below that is unseen and covered by the row above would also have a strip of tar paper covering it. Example: if pieces of wood are cut to 16”, then you’d typically be coving 8” of shingle by the row of shingles above. So then if you bought a roll of 24” wide tar paper, you’d cut that roll in half to get two 12” rolls... these would become your thin strips that you cover over the top 7” of the shingles, again that are going to be covered by the row above, and hiding any tar paper... that is your bullet proof protection system that is cheap and easy to do... the only other thing, it makes sure the shingles above are offset with the shingles below... at least 1” offset, so the joints don’t line up over each other... (which is the whole point of shingling in the first place... just basic stuff to understand.) It really is a great way to get rid (=use) of short scrap wood like pallet wood. Hope this helped... maybe it’s confusing, but I’m sure there are pictures showing exactly what I’m saying just a couple clicks/google search away.

[@melissajenkins1194]

This is amazing and would love to do something Like this someday! I live in Michigan where it gets very cold. I don’t know if I missed you saying it in your video but what state do you live in and how is your weather throughout the year? Also, I saw in comments you don’t do tomatoes or peppers unless it’s summer. what plants do yoh grow in your winter months ?

[@WineberryHill]

Connecticut, I am actually going to try rise and shine summer squash this year because of its vertical habit but in the winter months, it’s definitely the brassicas and lettuce and things like that.

[@GMC-qo9xi]

I’ll assume you thought about this idea as well and reasoned against it for expense or difficulty-but it’s a very beneficial one imo. Is to insulate horizontally the ground around the exterior perimeter of the building itself. Butting it up to the footing or bottom of the insulated wall, and sloping it slightly downward to run moisture away and to protect the foam with progressively thicker dirt the further out... 2’ of 3-4” would suffice, but 4’ of 4” would basically bring the 55° right up to the surface and then technically no insulation at all should be used inside, as whenever the temperature is above 55°, the actual heat in the ground it’s able to come up from below and or go down from above... And theoretically you can increase (=store) the temperature of the ground beyond 55° and then take it back out from the surface as needed on cold nights. If interior in long winter stretch barely reaches 55° and/or sun doesn’t come out, then ground will gradually cool as it’s uninsulated, but at least (the otherwise frozen) ground around the exterior perimeter won’t be stealing heat from underneath the greenhouse-as long as it’s well insulated. (And proof of concept can even be found where early snow fall keeps the ground from freezing... like in the years when it falls in November before ground is frozen as long as it stays and is thick enough, you can typically dig it with minimal frost/hardness and vegetation will still be ‘fresh’. And surface will be around freezing point... but then if you had put a piece of insulation there first, then snow on top, it will indeed be relatively warm underneath right up to the surface...)

[@WineberryHill]

Yeah, we are on the same page. There wasn't anyway of doing it on the outside of the structure because I literally jack hammered down to bed rock on the north and east sides. The south side is a cliff. Your idea is essentially what I did with the bed on the inside of the structure.

[@GMC-qo9xi]

@@WineberryHill ya, concept wise it’s the same engineering idea for slab on grade construction, to prevent frost heave (as well as heat loss, etc.). Ultimately, I think we’d all be following the Chinese model or better yet the basic earth ship concept... where the typical hoop houses don’t really make much sense for us up north.

[@GMC-qo9xi]

@@WineberryHill regarding the rock, that’s pretty difficult t9 work around..l the raised bed idea seems perfect though in that scenario. I’ve got a rock face (like cliff) that I’m fantasizing about building up against it... as it’s south facing and relatively flat at the base which backs up to my shop (like 100’ away).

[@WineberryHill]

Yeah, rock can be your friend in that instance.

[@GMC-qo9xi]

@@WineberryHill It would likely rob more heat than it holds. Might have to cover a massive area.

[@GMC-qo9xi]

Another way to use that irregular shaped styrofoam would be to grind/break it up and and then fill the voids from top of wall... like say you put vapour barrier up on the inside and then didn’t finish stapling the top foot, then pour you styro beads/small chunks down... you’d be able to see what’s going on and if it’s stuck or whatever and allow you to pat it down and into place. It would make more styrofoam shapes available to use, like appliance packing, etc...

[@WineberryHill]

Totally right!

[@GMC-qo9xi]

@@WineberryHill imagine starting an enviro business, working with recyclers to take all the styrofoam just that they usually have to send to landfill (and actually get them to collect it-like around here they don’t even want us to put it in recycling). Then turn it into a blown in “green” insulation... probably piss someone off and get lobbied against, but lot of ‘raw’ material out there to find a better home for, then the landfills!

[@WineberryHill]

I have a friend that did just that. Apparently, spray in insulation companies bag up a LOT of insulation that gets cut off for sheet rocking, etc. He insulated his entire 2nd floor (2,500+ sq ft) with crushed up foam. He'd sheetrock up one course and then pour it in.

[@GMC-qo9xi]

@@WineberryHill excellent. Another great use/source of otherwise garbage.

[@adus123]

It's interesting that you brought up the topic of shading, given that your design heavily incorporates wooden beams, which indeed cast a significant amount of shade. As a result, you're inadvertently missing out on a substantial amount of potential light and heat. In the context of greenhouses, the usage of glass is commendable due to its property of minimal light obstruction. However, the framework does impede some of the light. It's worth noting that glass excels in heat retention compared to plastic, although it comes with its own drawbacks, such as weight and cost. Conversely, while plastic can block some light, the relatively wide spacing of the supporting hoops helps mitigate this shading effect. You might consider a double-walled polytunnel with a blower system to further reduce heat loss. I find your ground-to-air heat transfer system intriguing, as I'm in the process of constructing a similar system for my own greenhouse. Incorporating heat storage in water is another effective approach.

[@silentvoiceinthedark5665]

I have concerns about the synthetic materials that you use to absorb the solar heat. They will release VOC over time, especially when they are new. VOCs in a closed environment are likely to get absorbed into your food crops. The 55 gallon food grade drum is probably OK but the 1 gallon containers may leach over time. Perhaps leaving them in the sun outdoors for a season may help. Sunlight does degrade plastics and cause them to give up the VOCs so after a season in direct sunlight you may be left with some very small amount of residual VOC discharge. Have you considered a thermal mass rocket heater?

[@WineberryHill]

Thanks for the feedback. Great stuff to consider. I have thought about a rocket heater, but I'm starting to think I wont need to add anything else, since I'm able to keep the soil temp inside the greenhouse at around 62˚F.

[@PeterLawton]

I can't share the same concerns. The plastics appear to be common, particularly those black plastic jugs. Such plastic is high density polyethylene, the same stuff used in milk jugs. If HDPE is offgassing any VOC, the level is extremely low, and any migration through the garden space and ultimately into grown food will be of an even lower concentration that what is already thoroughly safe. And the offgassing level may well be zero for all we know.

[@GMC-qo9xi]

In spring summer and fall, most greenhouses require a relatively large air exchange... And voc concerns should be dealt with, but generally speaking the time when they are inevitably the worst are the times when outside air is needed to cool. (First winter could be an issue...) Some people however are making relatively sealed greenhouses even for summer using the ground for cooling... making the voc issue a bit more of a concern.

Yeah, likely needs to be roughed up. There are some paints specifically designed to stick to plastic. What I have done in the past is just put a black plastic bag over the barrel...seems to do the trick.

[@mircozscherper9464]

Hey I Wunder where are you located I am on the west coast of Canada and we don't have much sun light in the winter more rain and clouds any ideas for that ?

I'm in the north east. Not all 15 of the things I do will work everywhere, but some of them inevitably will.

How long does your crisco candle/terra cotta heater last? Do you run it 24/7?

[@willmakxam3834]

Question. Inbother thermo green houses. I have noticed many heat thevgeound all summmer. Battery bamk thevsummer heat. Then use the addedbheat from the summmer to bebused slowlybover the winter. Question, are you doing this? Or are you only capturing sun heat from the fall and winter to keep the grreen jouse warm?

[@WineberryHill]

yes, essentially an earth battery

[@kkflower1111]

Do you use it in the summer? If so does it get way too hot? Thanks

[@WineberryHill]

I use the greenhouse year round. It doesn't over heat like a traditional greenhouse does. here is a video about how it stays cool: kzbin.info/www/bejne/rWjYdKWkj9NqY5o

[@jayhanson2224]

Do you need to change anything when summer comes around so the green house won't be too hot?

[@WineberryHill]

There are some thing I do like leaving the doors open and I switch out a couple windows with screens. Here is more on that: kzbin.info/www/bejne/rWjYdKWkj9NqY5o

[@cohen860]

If the greenhouse is so airtight, isn't that a problem with the terra cotta heater, for two reasons. 1. you need air to come in for it to work, and, 2. you need some ventilation for the carbon monoxide from the heater to escape?

[@WineberryHill]

It isn't vacuum tight. There is a fresh air intake, and an attic vent. That said, the plants would easily absorb any harmful gases.

[@PeterLawton]

@@WineberryHill Excellent point. CO2 is the main product from the heater and elevated levels of CO2 are great for better plant growth.

Добрый день ,😊ваш утеплитель -пенополистерол очень любят грызть мыши, очень чудесная тепличка, что в ней вырастили?

[@WineberryHill]

брокколи, салат, капуста, клубника, перец, фасоль.

Did you do a video on how to keep your greenhouse cool and well ventilated in summer? Peace

[@WineberryHill]

Yep, here ya go: kzbin.info/www/bejne/rWjYdKWkj9NqY5o

[@StellaLunora]

Paint the entire green house brown or dark brown? Maby camouflage? I'm assuming the dark colors will heat it up quick if you're worried about the summer getting too hot then camouflage since its layered colors of green beige black and brown. Or just paint it brown and ventilate during the summer? Would adding mirror's inside help with heating? Hmm

[@WineberryHill]

Great tips!

How Long Does The Crisco Last An Is It Messy

[@WineberryHill]

Depends on the details of your setup, air flow right, size etc. But a week and a half to two weeks.

[@joansmith3492]

My next greenhouse will have a thermal blanket to put down at night like they use in Chinese greenhouses.

[@raljame]

I put black weed fabric on the wall of a room with no lights and no windows, it did not collect heat, when the heater was off in the room the balck fabric was the same as air temp, maybe you should say that the balck fabric is a good way to collect heat from the sunshine that hits it.

[@WineberryHill]

Yep, it collects solar energy from the sun.

[@calliecordoba532]

Did you build your greenhouse.? Do you have the plans to share?

[@WineberryHill]

I didn’t build it. I am working on making the plans available very soon, so stay tuned!

[@weeverob]

your terracotta heater, how many hours does the can of Crisco last?

[@WineberryHill]

it will easily burn for a week straight. That said, I seldom need to burn it during the day, and really only need it on the absolutely COLDEST nights because of the geothermal aspects of my greenhouse.

[@weeverob]

@@WineberryHill excellent, tx!

[@hildebertocarreiro9232]

How long for burning clay pot?

[@WineberryHill]

Easily a week if not more. But I usually only use it in the COLDEST nights.

[@Strength_In_Wisdom]

Whats the floor plans

[@WineberryHill]

For the greenhouse? My greenhouse is so specific to my site and my geographic area...I'm not sure plans would help other people very much...

[@lochinvar5589]

How much did this thing cost?

You should create blueprints and sell them as kits.

[@eileenmcloughlin4778]

Do to the toxicity of plastics and unhealthy nanoparticles of pladtics, I would use ceramic or other nontoxic planters.

Can't imagine how much this cost? Most ppl could not afford it.

I live in Calgary Canada. Zone 3a or b. Lots of great ideas. Totally Impressive. I chose to live in Calgary, Canada rather than Texas because of family and the impressive mountain beauty. But I miss my pomegranate bush in the front yard. So greenhouse it will be... Have you also considered Sand to hold heat?

[@zanepaxton7452]

As much I like the using the thermal mass of the ground I can’t do that here on the north coast of California where it rains 75” a year and the water table is now at the surface of the ground with ponding occurring. The buried perf pipe would be full of ground water and the water would move the retained heat downhill…. That’s all a show-stopper for the climate battery thermal management idea for me where I live. It’s cool and very wet here. I’d be concerned about the perforated buried pipe that could collect ground moisture. A greenhouse is high humidity and pumping that warm humid air below grade could cause condensation if the ground is below the dew point temperature where condensation would occur. If that happens, there could be a moldy mess down there with no way to clean it out. I’ve yet to see any analysis as to how efficient the ground heat storage is or isn’t but the proof is whether it works or not. It’s hard to pinpoint where the temperature swings were day to night and how much heat gain were achieved over outside conditions. It would seem that the black inside surfaces would be more effective if they were on some sort of thermal mass right? Otherwise that hot fabric surface would only be re-radiating into the air only. That has no heat-lag that is desirable but it does harvest heat from the sun into the air. How do you get pollinators like bees into the structure? Then, how much did this cost and how many “sweat equity” hours did it take to complete this greenhouse?

[@trevorsmales9303]

Surely the black walls is the opposite of what you need for this ? why they are hotter is because they're absorbing more heat and not reflecting or radiating it back into the air of the greenhouse.

[@WineberryHill]

Thermal mass is the name of the game, that heat has to go somewhere…

[@trevorsmales9303]

Yes but on the walls it's over insulation therefore very little thermal mass in the covering itself. This is why I believe a reflective surface would be better on the walls.@@WineberryHill

[@WineberryHill]

I’m not against the idea of adding reflective surfaces especially in the winter time. Stay tuned maybe that’s some thing. I’ll add.

[@pewithmr.v723]

Would simply 'hay' not have been a far more eco friendly insulation option than all the styrofoam?

[@WineberryHill]

Hey, will take on moisture, and eventually rot, which would be less than ideal

[@pewithmr.v723]

@@WineberryHill I am not sure it would rot in the walls... Straw bale houses are much older than styro foam. Maybe a layer of humidity regulating clay could be the solution... Or 'cork' which can handle humidity really well but that would probably drive the cost up significantly... Just wondering about more sustainable alternatives to styro foam... Thanks for the great video!

[@saintamerican6105]

Bro spent $100k on a greenhouse instead of buying a brand new bmw, i love it!!!!!

[@WineberryHill]

100K! Check out this video I made about the cost: What's a "Free" Greenhouse ACTUALLY Cost? kzbin.info/www/bejne/ZqekaXuubatqic0

[@EfficientEnergyTransformations]

In the winter, the heat is accumulated through a sunny days, and released through the nights (clear nights are especially cold). In some Chinese provinces they rollable straw blankets for the night so to minimize the loss of heat over the most demanding heat-loosing-conditions.

[@markspc1]

You could call it "The Million Dollar Greenhouse" .

[@WineberryHill]

lol, sounds like you have been talking to my wife! But seriously I think I actually did pretty good. The majority of the materials were recycled. Here is a video I made about the cost: kzbin.info/www/bejne/ZqekaXuubatqic0
