I doubt this idea will work, but I will post it anyways. This idea is specifically for Drosophyllum. Most people use the double-pot method for , and the inner pot must be clay, but I don't know about the outer. My idea is get a mini bog and do the double pot thingie, but instead of one pot, you can put several pots with one seedling each and just water the bog if you want to water the plants. Don't know if this is a good idea, cause of that toxin they produce that supposedly kills other plants and hey as a bonus, you can even probably put a ping or two in the outer pot (minibog) area and everyone wins
