I would say join the FB page "Reptile and Amphibian Bioactive setups'. They have files there that list safe plants for the different set ups like marsh, jungle, desert etc as well as how to and you can always ask people there. Not really sure how many people here go full on bio set ups. I thought about doing one for Pat when i get his PVC cage but now will probably cheap out and just use substrate with potted plants like i do in the other snake cages lol.
Also as i learned the hard way, snakes tend to be curious and in the case of Luna and Dottie, they literally dug up their plants from the pots and killed them......
