I went a little crazy with the new hobby of propagation....

I can't decide if I should have a hoop house, cold frame, or maybe an extension on my barn shed that used to be a coop.

The coop/shed area:

It's on a mobile pad and has blackberries that have run into the pad area to the left. Not opposed to yanking them because there's an established bed for them in front of that. The back of the coop is East and the left side is South orientation. Here's a shot of the other side:

I have thought of putting cold frame(s) in the former pen area:

I also have a 25' by 40' area that I currently use for composting, temporary holding, and tomatoes in the summer.

I just don't know! I can see myself really expanding this hobby and don't want to lose the plants I've been successful with.

Thoughts? Ideas?

TIA
