Well I’ll cross my fingers that it’s not just a leaf haha. And I do! The one I have is from a offbrand called ‘CoolGrows’ on Amazon. I don’t think they have the specific size anymore (96x48x80) but here is a link for the grow tent.

Edit: vivosun on Amazon also has grow tents as well as Mars hydro I think. But they’re a little pricier last I saw.

Nice work so far! honestly though you just want to get a tent and a 100w grow light panel. if you want to get any real product. if you need it to be really small i'll link a 2x2x36 grow tent. same price as the 2x2x48 ones though. get a spider famer, mars hydro, or some good brand of 100w LED panel, not the cheapest one you can find. What you have is too small to grow a real plant, space and light wise. Good luck! <3
