Hydro and organic fert. 3:1:1 peat moss, vermiculite and perlite. Usually a different ratio but you don’t want a ton of drainage getting into substrate. Use bone meal, blood meal, pelleted chicken poo, etc for the fert. Act like you are doing organic potted hydro. Perlite will help with drainage and vermiculite will help the peat retain moisture. Get good peat or coco husk, or you will end up with a lot of drainage and not absorption. Don’t add compost like you usually would for outdoor hydro. Lighting is going to be a challenge unless you go LED in the right spectrums.
Or just do straight hydro in a self sealed container. Add an air stone if desired. Google growing peppers in hydro and the most popular videos are what I am talking about. Can’t remember his name but he grows and clones in pretty much any container, even baby wipe tubs.
Never done live plants in a tank for snakes, just what I would investigate before doing it.
