The glass certainly won't fall down. And there are a few seeds, mostly for basic gardening, cucumbers and tomatoes and the like. There's also a few chemicals, all in the vein of Miracle-Gro or the like, things that someone might use to encourage growth or kill weeds. There doesn't seem to be anything weird around here: it really is just a nice greenhouse that people can use!

Enjoy your nap, Xayah.
