Wife wants another greenhouse!

Gone But Not Forgotten
We got the rest of the walls done today and except for a few short pieces under the windows the boards are all on. Ran out of nails for the airgun. They are an oddball size and They only had one pack at Lowes the other day. Turned the spare gun heater on inside and had it up to 60F in less than 8 minutes. Will work on leveling up the stone inside and will probably need to claw another bucket full loose from the stone pile to finish it for the landscape fabric. The Amish boys liked using an air nailer for the boards. It helped speed it up as one was cutting and I was carrying the boards to the other one who nailed them up. We put in a hard day to get it all done. They asked if I could take them to our local gun shop to pick out some new bows. They want to upgrade and sell their old ones at the auction before they move. I will truly miss their help as I am sure they will miss my equipment and skills helping them.

Finally getting around to taking some pics with it closed up and all the windows in. These are all second hand and freebies so I have only $130 in windows and doors. The boards cost more than that! Working on insulating anywhere that is not glass and then will put floor fabric down. Then 2 radiators get moved in to help the tube in the floor heat it. Hope to have floor covered tomorrow. The tomatoes are crying for more room as some are over 15 inches tall already.

Very nice work!
Now, go relax!

I just finished reading the entire thread on this project. Very well done.
I noticed the glass and some plastic inside. I do this for extra insulation but I use Bubble wrap. It has air pockets that help insulate but more importantly,the bubbles tend to diffuse the light giving more exposure to the plants.
1/4 inch bubbles seem to work the best.
My green house windows are at 36" so I buy the stuff on 36 inch rolls. A staple line at the top and a 1" X2" weight board at the bottom and you can roll them up on the double hungs when you need to ventilate.
Stuff gets brittle the third year. But is cheap enough
All of the side windows are just storm single panes I got for 10 bucks each at a closeout.
I also use it stapled to the ceiling rafters, (4X4's) giving an additional 3.5" of air blanket. Amazing how much brighter the light is in the room all day.
My greenhouse is on the south side of the main house. Six feet deep and 18 feet long, 10 feet high, all glass and acrylic panels except for the 4X4's, and on a sunny day in winter,the furnace never comes on.
The air exchange is convection. The moisture from the greenery keeps the humidity up in the house too.
Brick floor radiates heat after sundown. I heat it at night with a 1500 watt, portable liquid filled radiator.

Southern exposure passive like that is a good way to go. Wife wanted something that would keep all her flowers all winter as well as grow the starter plants for the garden. When the sun is shining you have to watch the temps and ventilate or temps can climb quickly.

Yep, I have seen 90F on the inside meter on a 15F degree day. Orchids love it.
One can install thermostatic operated fans for that. Even use solar panels to provide power or,,,,,hook up solar activated marine fans for automatic operations. Simply little module units you just cut a hole and install.
Like I said, adds greatly to the heat in the house. Just have to get the hot air on the cold side of the building. A two story stucture lends itself well to the concept.

Wait for it.
Thought it was time to give this a bump as I'm finally getting around to THINKING about building one. 
Wind is a major factor here so it kinda rules out the normal type greenhouse like pictured below. It does seem to be a perty good buy though for the size so I still am thinking about it. Heres the specs from the add. I also have no clue what to use for heat as we dont have access to gas or propane, any thoughts ?
22'x45' Greenhouse frame for sale - $500
Metal Greenhouse Frame with endwalls, framing for around bottom, plastic with wiggle wire, door, and ventalation fan. Greenhouse frame is still constructed for you to see what it looks like when it is up, and we can take it down as soon as you are interested in purchasing.

That's a bargain for sure Cowboy.
As for heat, I haven't much to suggest, except for some passive systems.
Use manufactured brick pavers for pathways to absorb solar radiation. USe a solar powered recirculating pump and an underpath radiant tubing ton absob and re radiate the heat. Store the heat via water in a large insulated polyprop tank. A couple of storage batteries to pump at nite. One 45 watt hour panel should do it.
Use the thing for "extending " your growing season by three to four months.

Wait for it.
Well thats a perty good start, thanks Franc. I know very little about using solar for heat, but I sure am open to suggestions there as well.

You're other Greenhouses have the PEk radiante systems so youare halfway there.Well thats a perty good start, thanks Franc. I know very little about using solar for heat, but I sure am open to suggestions there as well.
You canuse a simple single loop sysem herethe collector is the samebrick floor as the radiiator OR you can set up a second system where one, A collector loop, is mounted high in the structure collecting heat and the other radiates it later at nite thru the floor.
Harbor Freight sells a packaged 45 watt hour solar panel system for like $200 bucks,,,,,with an inverter/controller. Just add a battery. Run the pump, or pumps, off the 12 volt side. Use the inverter for 110v to run common, and cheap, tmers.
Set the timers to run water middle of the day to absorb heat. Then a second interval at nite to re re radiate the heat. Adjust them for seasonal conditions.
Use glycol if you are worried about freezing. Pumps would be the only freeze sensitive weakness in the system.
Simple stuff and a rather automatic operation. Effectiveness would depend on your solar energy levels and how well you insulate the system, especialy thestorage tank. You could amplify it later with a propane or wood pellet fired exchanger.
