There used to be a guy on here who was growing a kava plant but I havnt seen him here in a good while. The only problem with growing your own kava is you would have to wait at least five years before you get to try it lol. It would be interesting, however, if you built a hydroponic chamber large enough to house the roots and grow it that way. You could probably increase te growth rate significantly and at the same time the flavour might improve because it wouldn't be submerged in dirt for years. It would be insanely expensive to run a hydroponic chamber 24/7 for around five years though :/
