Know not really gardening but use it in compost. Does anyone here use either of these?
No, but sometimes I use the whey off the yogurt I make, and it stores well in the refrigerator. Some people use kefir, but I don't know much about it. Guess you'd find it at a health food store? Thought you just drank the kombucha tea. I also like to use alfalfa tea in the compost bin as it seems to heat it up a bit.
