Hey y'all. Wondering if I could bounce an idea off you. I posted over in r/succulents but then thought this might be a good spot, too.

Long story short... I have succulents. I used to have a "plant room" with a lot of sun and they were very happy succulents. Now that room is my mother's bedroom and they are not happy in their new location so I was thinking of how I can keep em happy and healthy outside. NC is mostly temperate... Pretty mild winters, but occasionally gets a snow or ice storm. I am seriously considering getting some version of the Palram polycarb greenhouse... 6x6 or 6x8ish?

My question is this... What kind of foundation do I really need for this thing? Can I jus dig a lil trench and lay some pavers down? Or do I need to do it properly with the whole gravel and sand and all that? I'm thinking just a perimeter foundation so I can do the weed barrier/gravel inside for drainage. Thoughts? Ideas? Thanks!
