I wasn't sure where to place this thread, so I put it in this sub-forum.

I want to build a mini greenhouse since I do not have a lot of room for a full sized one. I am not quite sure what kind of material I need to cover the building with (i.e. plastic covering) for retaining heat. I think the framing will be the easy part.

The only other problem I can see is ventilation for when it gets too hot outside. I wanted to get the advise of this forum before I venture out to other resources. What ideas do you guys have? Have any of you already made plans for a greenhouse before?

Just curious what ideas people have.

When you say mini, what size do you have in mind? I realize that you're up in Park City, but you could come see mine if you'd like. The one I have is about 8' wide and 6' long.

Shoot me a PM if you want to come see it.

Hey thanks for all the advice. Christian I would love to come by and check out your greenhouse. SLC is like a 15 min drive for me, so it is not too far away. Sent you a PM.

You can do the clear corrugated plastic, they come in 6',8', 12' pieces. But its relatively expensive.

And they break easily, I used it on my coldhouse and I ended up shattering 3 just by bumping them with the drill when it was cold out. Next year I'm just gonna use good old plastic sheeting.

When you switch to poly film your heating prob will vaporize.
I get by with a fan and opening the door through about mid-May.
After that I give it a bris. Runs fine through the summer and
re-cover it in the fall. Use the good stuff like 4 to 6 mil but the
not so expensive 8 or so thickness. Given your summer heat
it will only last a season anyway you go so don't waste the extra
money on the ultimate oooowee expensive stuff.

Warp's flex-o-glass is the toughest, longest lasting poly there is. Most houses have two layers. With a small blower pressuring between the two so it makes air space between them and keeps them tight.

I just finished this greenhouse. I used 6 mil. Clear plastic used for greenhouses. I bought an automatic vent opener. Total cost just under 300 usd.

Send me an email address and I can send pdf file of the plans I used to build it. Also my plastic sheeting is rated for a couple of years and I live in Florida. Greenhouse has been standing for 3 months now and survived several nasty, windy thunderstorms.

Also there is a lot of places selling them for dirt cheap to repurpose.

That being said check out this old link - There are some pretty cool ideas buried in there -
