“Holy smokes!” Gregor exclaimed as he exited the van-body he had picked to spend the night. “I am going to need to do something differently if I am going to survive the winter” he said as he clapped his hands together and stomped his feet.
Then, Gregor went over to his parent’s house to eat breakfast while Blain went into Sarah’s.
Gregor was back before Blain had finished.
“So, Aunt Sarah, Papa said that the best place to unload the stuff from the back of my truck might be into one of your hoop houses. What do you think?”
Sarah put her on hand on her hip and brought her other hand up to her lips where she absent-mindedly nibbled on her knuckle, deep in thought.

“Well, I suppose you could unload into the biggest one. All I have left in that one are some trays of green-onions and I was getting ready to shut it down for the winter. Mind that you shut the doors when you are done” Sarah said.
“Blain, do you mind helping?” Gregor asked.
“No problem” Blain said as he swallowed the last of his luke-warm tea.
Gregor started his truck and backed it up to one end of the hoop house.
Gregor was clearly familiar with Sarah’s hoop-houses. Blain had never spent time near them because it was Sarah’s domain and she had never assigned him any work that took him inside of them. Besides, the daylight hours were short and by the time he had free-time, it was dark.
Gregor opened up the storm-door and beckoned Blain to enter the greenhouse.
Walking through the door, Blain was struck by the twenty degree difference between the inside and the outside temperatures. Not only was the air much warmer than the outside air but it was still.
“Why is it so warm?” he asked Gregor.
Gregor shrugged. “Sarah rolls up the thermal blankets every morning to let the sun in and lowers them every evening to keep in the heat. I suppose that between that and the water barrels…” Gregor said, pointing to the barrels that the growing trays were supported by “...that hold the heat…” and then Gregor’s voice trailed off.
“Well, I know where I am parking my van tonight” he concluded.
Blain looked around in disbelief. “No way in hell are you going to be able to fit it through THAT door” he said, pointing to the storm-door.
“The sides roll up” Gregor said. “Not going to be a problem. We just have to move enough of these barrels and stack the trays Aunt Sarah isn’t using and there will be plenty of room.
Blain looked the space over with new awareness.
“How many vans do you think we can fit in here?” Blain asked.
“If Sarah lets us move a few barrels out of the house, maybe two of them” Gregor responded as his practiced eye estimated distances and the curvature of the sides.
Knowing that he would be evicted from the CONEX as soon as a family showed up, it was a pretty easy decision for Blain. “I’ll help you get moved in as long as we make room up-front for the second van. I’d rather be in here from the get-go than to get the worst van and not have a good place to park it.”
It was almost noon before they had the interior of the hoop-house rearranged, the cargo from Gregor's truck moved and stowed and one side of the hoop-house rolled up. It took an hour to get the first van in. The longest part of that time was spent spinning the van around so it was oriented to make room for the second van.
The second van they didn’t even try to roll in on its own wheels.
Gregor popped two of the arched supports out on the closest side and held them up at the middle of the span with some long studs. Then he put a dolly under each end of the van and used the tractor to push it in sideways, already oriented the long way.
By then, the daylight hours were shot but Gregor’s truck was unloaded and both Gregor and Blain had “apartments” in Sarah’s big hoop-house.

Tip of the hat to "W" for technical advice.
How does Sara keep the water drums from freezing?
ReplyDeleteWhat grow zone is it?
Inquiring minds want to know.
Even in zones where temps hit freezing, using barrels 80% filled with water is effective in greenhouses as a heat sink. The barrels heat up during the day, and then give off heat at night.
ReplyDeleteIn the event a deep freeze sets in and the barrels freeze, having them only 75-80% full assures there is room for expansion and they will not burst.
I hear you, I'm familiar with the 80% trick but once those barrels of water are frozen, they become a Heat Sink.
DeleteI was wondering what weather is expected in this area.
My hoop house has a wood stove in it along with a posse of water filled barrels to adsorb the heat from it, so I don't have to feed the stove at -12 degrees.
Rollup insulation is as old as Ming Dinasty in China's greenhouses. But they used a Chinese version of the Crimean Oven a Kang bed-stove where a wood or coal firing in the evening kept the Emperor in Lemons in winter.
Ok - last paragraph above is key!
DeleteEvery Amish greenhouse I’ve ever seen has a wood stove…
DeleteThe coldest nights are almost always cloud-free. The next morning the sun comes out and can add fifty degrees to the inside of the greenhouse.
DeleteAlmost-always is not the same as always.
The woodstove is not to heat the green houses to human comfort levels but to have warmer spots for seed germination and to keep the back corners from dropping below freezing.
Even then, if you focus on crops like green onions and most leafy-greens then you can even let it dip to the upper 20s without too much worry.
Also, location is mid-south (Tennessee) at 1850 feet elevation. Not New Hampshire/North Dakota cold.
DeleteSuper interesting use of a hoop house, ERJ. I guess I never thought of them sized enough to fit one or more vans.
ReplyDeleteI've got a small version of a hoop house here at Rancho Whybother. It's about twenty feet long and twelve feet wide, with a height of about seven feet in the center. The thing is "Mother Earth News'ed" to death. The hoops are 1" PVC with discarded rebar inside them to help them retain their shape. The center "spine" of the thing is the same 1" PVC. This started to sag over two years though. I redid it with 1/2" thinwall conduit lengths inside it to keep it from sagging again. The skin of the house is "used but good" "free" greenhouse plastic I got from a nurseryman I know. I throw him some eggs, avocados, and pomegranates, and he keeps me in plastic. The ventilation is provided by a 12VDC marine "bilge blower" ($35.00) hooked up to a power supply through a 12VDC thermostatic switch ($18.00) made by a company called "Inkbird." I went with 12VDC ventilation to allow me to run it on deep-cycle batteries and a solar panel if needed. Bilge blowers are designed to evacuate fuel vapors from the bilges of boats. They're designed to be used in damp environments and move a TON of air very quickly. It vents to the outside via dryer exhaust hose punched through the end wall of the greenhouse. There are three 55-gallon water barrels in there to modulate the cooling of the greenhouse at night. Yes, they will freeze if it get too cold in the greenhouse, but this will be after they've dumped all their heat into the greenhouse for the benefit of the plants. They can also be used as emergency irrigation in a pinch. The floor of the greenhouse is "last year's" doughboy pool cover. ...I refer to the doughboy pool as "an emergency water tank I can swim in..."
ReplyDeleteI would recommend a hoop house to anyone looking for a relatively inexpensive way to keep stuff growing over the winter or to get a head start on spring planting. They have an amazing amount of space inside, and properly oriented, stand up well to wind.
A hoop house is a cheaply built Quonset hut, which itself is a simple, inexpensive, modular, quickbuild enclosure.
DeleteFor summer time cover, the hoop canopy can be changed out to construction fabric fencing (ugly orange or deep green color) which still provides sun shading quite a bit but lets the breeze pass through to any thing underneath it. Strong winds also blow through without attempting to pull off a solid sheet.
ReplyDeletePeteforester - Thank You for a lot of 1st hand knowledge of living under such a structure. The above information in this post was a hoop greenhouse located in south Texas. Strong sunlight baked our tomato plants, and cats loved the garden's soft soil as their litterbox. This hoop house solved the problems simultaneously.
Red neck time. I built one a number of years ago from repurposed wal mart trampolines that I got free for just cleaning up the mess that they were in other people's yards. Used a sawzall and wirewelder. Set the legs in a bit of concrete. Was stout as hell.
ReplyDeleteYep, Quonset hut ver ???
ReplyDeleteDo you recall a NOVA episode called something like 'Secret of the Chinese Bridge'? It was about a wooden arch bridge made of straight segments of wood or timber bamboo called a rainbow bridge. Might be a way to make the hoops for more hoop houses if you lose access to plastic or metal pipe. BTW the reason the rainbow bridges no longer exist is that once constructed while being used as bridges they were simultaneously used as forms to build masonry bridges.
ReplyDeleteI'm sure Blain took note of Gregor referring to her as "Aunt Sara"...
