FlowRider--thanks for stoppin by. In regards to the hydroton, I probably won't be using it again for a hempy bucket. Since you only water about twice a day, the medium has to retain some amount of water for the roots before the resovoir. If you do use hydroton, you need to make sure the roots are reaching the bottom or very close to it. this extremely stunded the growth of my smallest plant as it took the roots so long to reach the res in the hydroton. i was thinkin about a hydroton perlite mix, but i dunno
