On second thought, considering that 5g pickle jar is a whopping 18" tall, it would look pretty boss fully tanked. But that's talk for a different project. For my 3g jug, to maximize space, I plan to use no filtration, starting off heavily planted. It will be bare tech, having no equipment but a small heater. That kombucha enthusiasts site also offers heat mats that won't crack glass, so if I find some money lying around, I can really go for that swamp-in-a-jar facade. Well, wish me luck.
