that ground battery is a keeper; I'm planning on a chinese greenhouse next with a mass back wall made with 1000l water filled totes (solar heated), polycarbonate sun wall and a rocket stove bench in the middle to boost warmth in the colder temp. I'll add up led lighting.

Love this series. Here in South Africa materials is very expensive, so is electricity and water but I am trying bit by bit. Got the first 10m x 3m tunnel up and productive. Doing better than the outside crops as we had over 1000mm (normal < 900mm) of rain during December. New bugs like cauliflowers lice and snails. Working on the next tunnel, saving and buying materials on a month by month as our income is less than US$2000 a month, but take it season by season. Looking back we made much progress over the past 3 years. 🤗🇿🇦

Combine that hydronic with a simple Evacuated tube solar collector and you would not need the boiler. Even at -30C on a grey day they can still hit 50-60C on the output.

For anyone concerned about cost. The no freeze performance can be achived with 1000$ greenhouse of same size. The greenhouse from part 2 with inflated poly and heater. I added third layer bouble wrap inside and i can heat 24m2 greenhouse with 2kw for 15°C. We rarely get below -15°C.

I mean, if you can put in like 3 layers of floor heating and insulation, and 2 different heating and venting systems, I think you could put a light in. Like, lighting is an option. A couple hours in the early evening is all you'd need to simulate at least a spring/autumn days light and heat, if not full summer. 1 panel could handle that amount of work.

Thanks for the information! Honestly, the increased overwintering potential and productivity gains in the shoulders come at a great cost. I can only see this being useful in an area with limited greenhouse locations. Otherwise, seems way better to have 3-4 "v2 high tunnels" for less than half the cost of one of these.

Love your Contant love your book. If you had a cement floor, couldn’t you theoretically put an extra bed in and have the bed on wheels so that you could move them in such a way where you only had one walkway, but could move them around to expose another walkway behind them, no question is in addition to this being a pain in the butt when you have to move them with this interfere with any of the heating.

Curtis, for ergonomics have you thought about either raising the raised bed height, or lowering the walkways to put the growing height ~waist level? My grandfather built a U shaped greenhouse with excavated walk ways to keep the growing medium waist level. this presented a center growing bed and the U shape outer area growing beds. this worked good for him and my grandmother to work the garden. for reference this was made in central FL.

how could you do that, as a blower to pump hot air down into the ground, to me is soo noisy. the thing is, how would hot air be captured in which to transfer into the water. I guess a water pump would not be so noisy, plus cutting the cost of all that work in laying ducting with which to put hot air into the ground. warm water can be used, to water the plants.

I wish you were ten years older than me instead of twenty years younger! You are literally doing things I wanted to do years ago and just kind of felt my way through. Sometimes it worked, other times because of one stupid flaw, it didn't work nearly as well as it might. We also have a wood boiler but were warned off running lines into the greenhouse by a plumber (former farmer) who felt the lines might dry out the beds. However we were proposing to run the lines MUCH more shallow than what you have done, so you'll likely escape that issue. Are you concerned about water accumulating in the floor material, as I notice there is not really a proper drain. In our area (Central Ontario) there is an extremely high water table and if were to dig a 3 foot hole I would have a 2 foot deep swimming pool

Hey Curtis, we have been binge watching your video, we are about to start construction on a greenhouse of our own. Questions about the climate battery, do you think there would be much benefit of painting the upper plenum pipe black to absorb more heat from the sun. Also we are constructing next to our garage. The garage is roughed in for in floor heating but we are not using the system. What are your thoughts on using the garage floor concrete as a thermal battery? We do keep the garage above freezing, so it may benefit from that too. Anyway, love the videos, keep them coming.
@offgridcurtisstone
@offgridcurtisstone Год назад
There might be. Rob Avis did that to his, though it's hard to say because even if that pipe is black, on cloudy days, it's not going to make a difference. On sunny days, it'll get really hot, but it's hot in the greenhouse on sunny days anyways.

@mervynshute880 Год назад
Googled it. 6mil in decimal point relates to mili liters. You cannot mean this. Therefore 6mil must mean . 6mm/millimetres. Which is = .2 mm, or around 200 microns. On your website do you go into the construction details for the roof, cladding Deep winter greenhouses. Could translate to . All year round greenhouse growing. Which is optimum for the amount of work that goes into the construction. This then brings the attention to . Light transmission, and then heat transfer . How efficient would you say, your design is for commercial application. That’s seems to be a short fall. Eg fresh air circulation, and humidity control.

I’ve enjoyed a lot of the things you do, but there are a lot of confusing points you make. “The greenhouse sits higher in the ground, so it stays warmer”. Burying the greenhouse deeper, would actually keep it warmer. Not insulating the exposed upper ledge of your concrete wall will negate any benefits of the insulated outer edge, if you do the math it’s a very significant surface area. If you aren’t heating the greenhouse with a solar air heater, or some equivalent, circulating the air from the top of the greenhouse to the soil is… actually probably going to cool the soil in the winter. These were just some initial observations, but I think you’ve incorporated some cool systems in a somewhat counter-productive order.

I wonder if it would have been better to put your "climate battery" towards the top layer, and put your boiler water pipes under that? That way you could have first put down a 2" layer of insulation foam board, then your heated pipes on that, then your sand and "climate battery" above that. The insulation foam would insure that you are still getting the full benefit of your water pipes, after it heated up all that sand. It's hard to say about this though. You would probably have to build another one like that to be sure. I don't know enough about the stats of a climate battery. also, maybe burying your water pipes too deep would end up making them ineffective. It's hard to say
