I need a new greenhouse.

I got rid of my greenhouse the other day. It was in pretty sad shape.  Snow and ice caused it to collapse back in 2014.  I did what I could to fix it and it made it through last year.  Then we got more snow this year and it was pretty much done.

 

It had a large hole in the corner which caused to not hold heat.

On top of all of that, the zippers on the door were shot. 

So... The greenhouse went away.  I'm hoping to get another one at some point.  I want something with some structure that can withstand some snow.  I'd also like something with roof vents to release the heat and not cook the plants.  I started seeds this year without using the greenhouse at all, so maybe I can get by without one.
