Gonna get a 10g going with a continuous brew. Gotta keep it warm though, about 73 degrees. There can't be any filtration or movement. If I leave the heater dead center at the bottom, will convection be enough to prevent the heater from burning out too quickly?
By the way, I met the owners/producers of Lion Heart Kombucha at a wedding a few weeks ago, really nice people. They would probably be willing to give you some pointers if you write them. http://www.lionheartkombucha.com/
