HEAT your Greenhouse (15 Ways) 

Wouldn’t work for me, but such a great idea!

I vent my dryer into the greenhouse also

What do you use to keep the dryer lint from your plants? I had this thought for my chicken coop. 🇺🇸⚔🇬🇪

@@manchu6005 thank you

@@manchu6005 Most dryers have two filters to minimize this already.

Typo. Meant GAHT.

Yeah, I'm excited about using the GAHT. But I would like to think that all of the other little things add a few degrees to the overall temperature also.

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?

People will need to employ more or less of these methods depending on their longitude. By themselves, each of these methods mean a gain of a few degrees.

You bet!

Glad you liked it!

100K! Check out this video I made about the cost: What's a "Free" Greenhouse ACTUALLY Cost? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0vA8Hx8F7Sk.html

Plenty of sunlight, plants are happily growing

We learn huh

awww shoot! Sounds like me. Every spring I get my water tanks filled up for the garden and then I forget to turn off a hose and I have no water by the end of June when I desperately need it for summer - aarrgh!

I am!

yeah, winter is basically here also, upper 20’s to lower 30’s at night now.

We have our greenhouse turned a shed.. lol..for patio furniture these days and for the winter. Hoping to build a much bigger hooped greenhouse next year with whatever I can get for FREE or cheaply on the buy and sell sites!

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.

Great idea!

Thanks for the sub!

So nice of you to say. Here is a link to a video I made about cooling: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-w7uCrnZn7-8.html

@@WineberryHill wow. You are amazing. Thank you so much for the really prompt reply. 👌👌👍

Mine is 10x20 feet with 1000 gals of water in it. I also use just a Milkhouse heater when outside temp drops below the mid-teens. I'm in the Missouri Ozarks. 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.

@@loudidier3891 what kind of containers for water?

I actually built the greenhouse with this in mind. I put composting set up (video here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MAIU3cQICHY.html ) 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.

Great tip!

I think thermal "banking" is the low hanging fruit. So as many thermal sinks made of things like rock and water reservoirs (and adding black surfaces over them for solar collection).

@@WineberryHill Glad to hear, I was also hoping that is the case. In my design, I only have a couple systems in play...massive thermal bank (small pond+aquaponic system) with a rocket mass heater under the mass.

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.

Hi, Nice to have you visit!

@@WineberryHill Keep up the good work

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...

@@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.

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.

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.

Right, I was talking about the planning phase.

That's the beauty of a Geothermal/GAHT system. I'm able to take advantage of the warm air in the winter and the same effect in the summer (Ground air is 50˚F year round). Check out this video I made about the 7 ways I cool my greenhouse: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-w7uCrnZn7-8.html

Thanks! Footprint is 16'x20', and the bed is 12'x12'. Here's a video about cost: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0vA8Hx8F7Sk.html

yep, that’s how it works

I guess for me I need to figure out the point where I'm also able to cool the greenhouse in the summer. In that instance it might gain too much heat when I don't want it.

@@WineberryHill Venting roof windows/skylights, since heat rises, it would escape. Manually or electronically operated. Just a thought. P.S. Window shades, and since your windows are on an angle, use an aluminum track system to thread shades to stay in place up against the window. As well as skylight shades, all of these can let light through without the heat. BTH the addition of the foyer is very smart.

Totally right!

@@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!

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.

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

So it’s actually not sealed that tightly there’s plenty of air movement in the structure that said the plants would love any extra CO2

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.

@@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.

@@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).

Yeah, rock can be your friend in that instance.

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

Those are designed for burial.

Yep that's also a good idea. I don't need it on mine since it's able to a considerable amount of heat.

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

New England zone 6b. Consistently in Winter, the low to mid 60's (f) at night. Mid 70's (f) during the day. We had a -3˚f morning a month ago and it briefly made it to 49˚f.

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

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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-w7uCrnZn7-8.html

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.

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.

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.

Absolutely I asked a plastic expert and he whispered. Use glass. 💙💜💚

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.

Yep, it collects solar energy from the sun.

yes, essentially an earth battery

Yep, here ya go: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-w7uCrnZn7-8.html

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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-w7uCrnZn7-8.html

Stay tuned!

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.

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

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

Great tips!

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.

@@WineberryHill excellent, tx!

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

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

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.

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...

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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0vA8Hx8F7Sk.html

@@WineberryHill He-he. If the power goes out in the winter at least you won't freeze 🙂

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