Ancient Greenhouses

It's fascinating how people back then, but also just some hundred years or so ago, opted to build building that will last and that were a piece of art. Today we are all about wham bam thank you mam. What kind of heritage will we leave to posterity? Decrepit concrete block cities.

exactly!

Survivor bias will probably make us indistinguishable from prior era's, a lot of the perception you have of old houses is already the result of survivor bias most people historically did not build houses to last we are just significantly more likely to see the well made houses survive to the present.

Nice as always! Paraffin can explode like water and it can catch on fire as well so be careful. Though water has the highest volumetric heat capacity (substances ability to store heat energy for a given volume of space) there are times where paraffin could hold more heat than water. For example using a certain type of paraffin at a certain temp ranges, with phase change only in paraffin, it wins. Where phase change takes place for both substance the energy stored for water wins hands down. BUT sometimes you want the temp to change from liquid to solid or vis a versa with very little changes in volume and nothing works better than paraffin. Sometimes you want to use paraffin only at phase change for higher temps from solid to liquid to main certain temps at the same temp, and again paraffin wins at those temps At the same time, if paraffin boils, kaboom. And it can be highly flammable so be care In designing in safety precautions and redundancies of safety. Just wanted you guys to be aware just in case. Lol

Thank you. You have excellent videos. Keep it up!

Thanks, will do!

That smoke-heated floor idea got me thinking. Some hydroponic growing operations in Colorado supply CO² to their greenhouse to boost production. Now I understand it's delicately regulated, and helps best in certain stages of growth, but what if you could reasonably siphon off some of that CO² from the smoke and trickle it into the greenhouse in a way that would be conducive to growth?

[@SimpleTek]

interesting

[@elenidemos]

Awesome info, thanks. Learned several things today. But the cucumber he grew were technically cucumber, but no where near as selectively bread as the ones we use today. Skin is bitter & much less flavour, while being thicker & more chewy/leathery. The flavour the flesh did have was also slightly bitter.

Thanks for sharing!

2nd! You have great content. I look forward to your updates. I learn new things every video. Keep up the good work!

Thank you!

I live in Quebec Canada, we built 2 small greenhouses in a urban city and we LOVE it Now we eat fresh vege april to December (January February and march we eat frozen or dehydrated vege for soup) In February Im going in the greenhouse put some seeds on a Frozen compost and early in March the harvest crop pop up (temperature soil 0 to 10C ) In april may everything is in place in the greenhouses and grow faster than outside. Its magic

[@SimpleTek]

That's awesome! Cheers from Manitoba!

You guys should check out the KZbin video, entitled “secret greenhouse of survival” very cool. He’s even got a book printed which I highly recommend wealth of information.

[@SimpleTek]

Ok

[@Tarabaspence]

Good ending. I am weed oriented but believe there can be specific crop greenhouses such as east Texas muscadines or other crops like wasabi. Efficiency and expenses are key to our future.

[@SimpleTek]

Hint, most anything geared towards growing tomatoes will grow your crop

[@redstone1999]

@@SimpleTek I learned a lot from pot growing information. Unlike commercial greenhouse food/flower growers back then. They held back on info to sell books/courses, whereas pot growers shared freely the technics and know-how of indoor/greenhouse and outdoor growing of their choice of crop.

I was wondering if there was a way to make transparent material that was not glass. Ingenious - oiled parchment and the like.

[@SimpleTek]

cool eh?

[@garethbaus5471]

Acrylic is pretty good.

[@emmaharden9296]

That heated floor is what we call a Rocket Mass heater. I have one in my sun porch.

[@SimpleTek]

they work well! who'd have though they used them in Korea over 500 years ago!!!

[@gsmscrazycanuck9814]

Interesting. Innovations came more during the global cooling events such as the Little Ice Age.

[@SimpleTek]

somewhat!

[@gsmscrazycanuck9814]

@@SimpleTek all the dates you mentioned were cool periods. Greenhouses will be a vital part of food production going forward.

[@shamanking5195]

Here is an Idea ; I wonder if is possible to build a greenhouse with a regular roofing materials and bring in the sun light using mirrors or solar tubes ??? inflated plastic side walls ??? if yes , can we use geothermal to cool it down ???

[@SimpleTek]

interesting idea

[@nodigBKMiche]

Great video, Hawaiian pizza with ham & pineapple, possibly bacon, was a Canadian invention😊👍🏼. I guess that makes it N.American cause we don't grow pineapples in Canada 😊👍🏼

[@SimpleTek]

we grow some pineapples in greenhouses in Canada now!!!!!!!!!

[@fridgemagnet9831]

The Chinese use heated floor for their homes, like a small raised platform with a fire below, I guess that's a similar idea for Korean heated greenhouse floor.

[@SimpleTek]

didn't know that, thank you!

Appreciate it!

The floor was turned into a giant rocket stove

[@craigsouter4867]

What about using a stone heat sink with an air blowerpulling heat from the peak where the most heat is and blowing it down into the stone and radiating the heat back

[@SimpleTek]

exactly!

[@redstone1999]

​ @Craig Souter A closed air loop from subfloor to roof peak and back to subfloor will work without a blower. Not as effective as fan blown air, but it is automatic and no power or electronics required. Nothing stopping us from installing a duct booster fan in pipeworks. If power outage happens, air movement will still happen to keep greenhouse temp above outdoors temp.

[@technosaurus3805]

No mention of the hanging gardens of Babylon?

[@SimpleTek]

good point - were they a greenhouse or a garden?

[@technosaurus3805]

@@SimpleTek Information is scant, but they were probably the first documented manmade construction for the purpose of growing a large variety plants... complete with an irrigation system using an Archimedes screw and possibly a water wheel... basically an open air greenhouse where evaporation of water through the plants would have provided it's own localized climate control in the hot, arid environment.
