Default DIY Greenhouse my way

Just finished it today... Kinda proud of it...
12' x 14'
Polycarbonate roof.
Three 2' x 9' growing tables with lower shelf, and a 2' x 6' potting bench
Windows (recycled patio doors) from an apartment house redo at $25ea. Entry French door from the local 'Restore' had to rebuilt the wood frame but only paid $55 for it
Decking, purlins, growing tables all local rough sawn pine.
Water, 20amp power, 16" thermostat controlled fan, wall mounted LP heater coming.
Was fun, first time playing on a mini-excavator, bought myself a gas post hole digger from HF (bad ass toy)...
Was a lotta work for an old man. Pretty much everything that could be done by one person, was LOL..

Great job I was quite proud of the one I built for my wife (8x10) till now I’m not showing her yours! LOL. Is there any heat source so you can use it year round?

Getting a wall mount LP gas heater.

It does have a full length ridge vent (why it has a metal roof cap rather than polycarbonate). Thermostat controlled 3,000CFM fan in the gable end is overkill from all I read. But this is my first greenhouse. More?

I've had greenhouses for the 35 years (until I moved to NC). Even up in ND, mid-summer sun might heat that up quite a bit. Consider getting a piece of Aluminet shade cloth, 30% is probably sufficient. Gothic Arch Greenhouses in Mobile AL will custom make it to your specs for the best price. What are you planning to grow?

That's nice. How much all in? Looks like you have the space for it, check out "earth battery" greenhouse climate control. It's pretty slick.

Mostly starting veggies, I'm sure we'll have flowers too.. We have two 2' x 100' raised gardens along our fence in the back yard, adding about 500sqft next to the greenhouse.
What triggered the project was we planted in May this year, THREE times. We had some 10" of snow total and a hail storm in May.... Lesson learned, so we will start everything in here next year.
Floor is full 1" x 10" rough cut pine with 1/4-3/8" gap between each board. My thought is water will run through it, and in the summer heat, if I close the windows and hit the fan, it sucks the cool air from under the floor, works well..

Bought the thermostat/humidistat already. Thanks for the heads up.
I've tried not to figure out what it cost, I can tell you the roof alone was over $500, $500 in glass, and I have some $200 in store credits from Menards 11% rebates. I'll guess $4000... said'n'done. Much of it wasted, I planned it with 9' ceiling height, when I got the first wall up decided I didn't like it, 400lbs to the dump, all the 10' studs got cut down, gave away like 6 or more sheets of the OSB, a lot of waste due to poor planning.. Oh, and almost all the #1 cedartone pressure treated you see was leftover from my two pergola projects in the spring.

Roof vent should be good, consider the shade cloth mentioned above.

Thanks John
While I was waiting on the siding, and those four vent windows to show up I had those openings still covered with house wrap. Well, it got really HOT in there quick. I planned right then to have a shade cloth made that can be rolled out from the sides and hung from the bottom chord of the roof truss. Also going to make a roll up shade or curtain for the east and west windows for summer.
Snooped around that forum THANKS, it will be helpful, a LOT of information there. I will join, hope they don't mind that I'm not from Texas.

As a "Greenhouse" at that size it doesn't require a permit here. Of course I didn't describe it fully to building department As a she shed (which it kinda is) anything over 120 sqft requires a permit......

We use shade cloth on my 20x48 hoop house. People with glass paned GH often go the spray route.

One word of caution, insects will find your GH appealing in the winter/spring, especially with 3/8” floor board gaps.

i would also consider putting in a deep sink to wash pots with and an on-demand water heater. Mist bench with heat mat for bottom heat is also great for starting seedlings.
