you can get them on ebay..they are about 4" in diameter..
I started with a bottle commercial Kombucha, I added it to a wide mouth 1/2 gallon mason jar, 6 pac at Ace Hardware reasonable price.
long before it was done I realized i'd have to go "Large".. the jar I used formed a SCOBY and was acidic .. so I started a 2 gallon jar with it. a big glass lid on a glass jar, the far left jar in the photo, in the kitchen utensil isle at Walmart over by the canning jars.
- my Continuous Culture set up.

I got the glass cylinder Continuous Culture jar off Amazon, i'm an amputee, one handed, it was hard to deal with big jars.. this system is really easy and convenient. it's in a small cupboard and I heat it with a little ceramic heater in the winter.. i'm going to box in that shelf with a drop down door to make a work space.
