Building a Green House.

[ljjhouser]

i have enjoyed all your pictures. Including the "Last Barn Build". But can't hardly comment on the pictures without admiring the WIDE OPEN spaces and fantastic land. Makes me wish I was there and had a horse.

OH also, nice project.

A greenhouse in on our list to build as well, but it will be a little while yet.

About those geo thermal loops. I can see them working in the cold regions of the US as long as they're below the frost line. But, what about down here in the south? Anyone have experience with them in the south. The only thing I have is that my well driller tried 2 things and said it wasn't worth the effort. 1) Since he's a well driller, he drilled well holes for a geo-thermal Air Conditioning system and said it was not cost effective. 2) He dug a root cellar, but the top was covered with the floor of a porch and the "roof" was uninsulated so that doesn't really count in my book.

What I've read about the geo-thermal tubes is that they have to be down about 8' and use a small fan to move the air thru them.

No it just needs a circulator pump. I think he has geo thermal closed loop ground source type system. All large motels have those pumps to circulate hot water to keep it readily available to each room. You have to have an air purge at the highest point to get all air out.

I'm in the south and have put these in. 20 miles and I'm in Louisiana. You don't have to drill a well.

Framing done, waiting for metal and translucent panels.

Some folks here built one. I guess they had a plan from up north. That thing has a 12/12 pitch on it. Even yours looks like a 4/12 pitch. Much easier to deal with. They never skinned it after the first time. Just framing now. They should put metal and a few scattered pieces of fiberglass sheathing on the roof to make it usable. Around here you can grow till November. We always plant corn on valentine's day. Some things will grow all winter if it doesn't snow my mother has a green house area and it's nice to have plants already started before setting out. Now we have major problemo with coons. Took dad 5 big live traps for them. Can't use foot hold traps because of kids and dogs, we love both. Dad's just hauling them 20 miles away and letting them go. We did grow over 6000 watermelon, but it won't happen this year. I'm talking a pack of fur bandits with black masks have hit us on the regular. Fig trees stripped. Peach trees no peaches. Fat coons everywhere. Them live traps and sardines are rectifying the situation.

Can't emphasize enough the importance of good ventilation in a greenhouse, it can be 40 out and 100+ inside when the sun comes out. And the temperature goes up really fast. In a greenhouse the size of yours a thermostat controlled fan and inlet shutter is a must!
In the meantime frame in the openings in the gable ends to accommodate the fan and inlet shutter, at least large enough for a 3' fan. Put temporary doors or shutters on them.
Even cloudy days will often result in significant thermal gain. It's not unusual for my greenhouse to be 80 degrees when its 55 and cloudy. Usually if you can tell where the sun is through the clouds there will be gain.

Sorry haven't posted in a bit, I've been busy with hay.
Here are a few pictures of the progress. Still need to put up 8 more wall panels but ran out of screws. Should be done by Friday. Then I can start working on the doors. They will be sliding barn style doors.

Not really greenhouse related but I got the fuel tanks finally. The summer tank is full. (thanks Brandon)
I will fill the winter tank in January. The strap was on because it was still empty at that time.
It is so nice to not use 5 gallon gas cans anymore.

Does the fuel company come out and fill it for you? My neighbor did it for awhile, but quit because it was too expensive.

Yes they come out and fill it for the same price as the pump price. (red)

The shell is done, now I have until next spring to get the raised beds setup and a watering system.

 

[EddieWalker]

Looks great. How much of a temperature change is there inside the building?

 

[JJT]

Very nice, I'm jealous.

I have not checked it but I can tell you it's significant, even with the doors open.

Thank you, we've been thinking about it now for 4 years. We waited until everything was super expensive before starting.

Spring is trying to come again to the Bear Lake Valley. I figured it was time to get something going on the greenhouse. First, getting access to it. The Robin got in somehow and that is proof that spring is coming..

We have the raised beds ordered. (water troughs) We'll get working in earnest once we get them. Of coarse, an automatic water system will also be installed. (by me)

I'm also glad that with the record snowfall we've had the greenhouse and barn are still standing with no damage.

WOW, that's a lot of snow!!!!!

Since I don't know anything about living where it snows, what happens to the snow when it lands on the greenhouse? Does the heat inside the greenhouse melt it so it doesn't build up?

It will build up while it's snowing but slides off soon after.

Nice job.

What type of translucent panels did you use?

Wife and I are putting together a little plastic covered greenhouse made from a recycled portable car shelter, and were thinking of making the ends solid eventually.

Thanks,
I don't remember the name of the panels. I'll find out and post later.

nice Greenhouse. I'd be afraid of the snow sliding off and cracking the side panels.

The panels are very durable and so far no problems. I would say whatever survived this year is good to go for many years to come.
