Default Phase Change Salts for Passive solar greenhouse?

Been doing a lot of pondering here of late about how to stay ahead of Brandon's Shitstorm. Mama has wanted a greenhouse for years anyways. So, I've been exploring options. Barrels of water are high on the list. But, Calcium Chloride Hexahydrate is sort of interesting. I supect I can DIY this way cheaper than what is commercially available https://insolcorppcm.com/products/templok-pcm-tile

The mistake most people make is way to much heat. Plants are not happy with more than 80 degrees. Phase change salts are good to store and release heat, but not to produce it in winter.
I would consider ground heat seriously. Can you grow oranges in Nebraska?

Ditto here, Ive been on the phone talking to sales people, tomorrow Im likely dropping the hammer on a 10x18.

I dont know a thing about the panels, but gonna have to read up on it. I was wanting to bury some pipe and heat it with ground heat.

In the short term its gonna be black water containers and maybe wood stove ?

Shits and Giggles have your future planned, some things the average person is not able to understand, the left says.
But food independence from government control is a very important thing. If you remember "prepping or"hoarding" was to become illegal under the 0bozo regime.

In America you do not live in a cold climate.

I know you think you do. But agriculture flourishes in much colder areas just north of you.
Look to your northern border states and copy some of those ideas. Food storage, a skill in itself(hoarding) is a skill needed for most of the flyover states.
I have run a greenhouse for many years when I had a family to feed. In the beginning I was obsessed with capturing all the heat and being efficient, and my plants fried. I learned the hard way that too hot or too cool is bad. Keeping a greenhouse cool is a hard thing and requires major monitoring or thermostats.
I found planting in the earth was the most successful way, sort of a greenhouse over your garden. This helps with the humidity requirements, and as heat rises, it helps cool the plants. In fall, the soil helps warm them.
Which is why I say use earth pipes for heating and cooling and forget about year round production. Although, that Nebraska retiree can feed me those words with his oranges.

My daughter and SIL, in the city, are showing their country roots in providing themselves with fresh greens all winter from a bench in front of their living room window. I gave them a grow light and that boosted output. Some of it is sprouts, and all I see is boxes of green leaves. They have continuous production with water and nutrients and light.

A greenhouse you have to buy specialist materials for is probably self defeating.

In our climate the greenhouse serves two main functions. growing on the shoulders and growing things that shouldnt grow here.

You start your plants in the early spring and plant them out in the garden in early summer when you're planting the same thing again directly. your greenhouse started crop comes fit first then your crop planted naturally.

Meanwhile the greenhouse grows things sun/heat loving plants like tomatoes or peppers for the summer. in late summer you plant a late crop of the things you started the year with and they should be ready for autumn.

with a good spread of varieties it should be possible to have fresh veggies of some sort for 9-10 months of the year and then you're into storage/preservation.

The price of specialist materials to gain an extra few months growing I'd imagine would cover the cost difference of a lot of vegetable price inflation.

An in the ground greenhouse with just the roof above ground will give you the earliest and longest growing season.

I've been meaning to ask how did Walter's greenhouse build come out?

+1 on that. Whereas we were able to keep the greenhouse warm enough over the dull, gray winter using an electric heater (and an uncomfortably high electric bill), when the outside temp got to above 30*F combined with some sunny days, the inside temp quickly climbed to over 90*F. I'll be adding 2 more automatic roof vents to help release the excess heat.
