Are there any indoor grow chambers on the market for non-cannabis growers?

Many of the indoor grow chambers on the internet market are obviously made for stealth purposes/efficient cannabis growth. But I'm looking for a chamber with much lower initial costs and something along the lines of a chamber for the following; Tropicals, Veggies, Carnivorous, or anything else.

The problem besides the obvious high costs also includes functionality. I don't need CO2 filters or an illusive appearance ex) filing cabinet, computer, etc. I also am not too thrilled with the zipper and plastic boxes for sale either.

Anybody have any suggestions for a very picky grower like myself.

Side Note: I'm not knockin the cannabis growers but I cant make 1000$+ off of a single crop so the search must go on : )

Good Growing,
