It can be very simple. The inspector came and saw my small shade house, looked at a few plants and mentioned some pests he saw on them, aphids, etc. and left after 10 minutes. Really no big deal. They like to see plants up and off the ground against nematodes. Don't have anything on the prohibited list. It could be a good gig for a younger person and there is money in it if you can develop skills. I suggest grafting if you like that and finding something you could specialize in that others aren't doing. A niche strategy where a need isn't being fulfilled. Philodendrums are fantastically expensive right now but if you get things right they should be lucrative, mostly they need heat and humidity. Good luck, starting a business at a young age is really a great thing if I were a parent I'd be all for it.
