Greenhouse enclosure?

[charlie&Shelbie]

I'm trying to figure out an enclosed chamber for my (approx) 1 year old sulcata to keep the humidity in. Rooky here and thought an open top was the way to go since that is what is readily available at reptile shops etc. After seeing someones post with the Lifetime raised garden bed with vinyl enclosure it got me thinking. I found some other greenhouses online and was thinking about building a wooden bed to fit the greenhouse. Then making sure the bottom is air tight. Has anyone used anything like this and have good results?

These are great but with a one year old sully won’t last for but a few months. Maybe there’s a way to connect multiple covers though?
