Kitty litter as hydroponic
grow media?
I have been reading on various pond sites that some people use non odorous and non clumping kitty litter as media in slotted pots to grow various water plants. The argument is that the cheap stuff is just plain clay. There seems to be some agreement that the clay may bind phosphorous and thus limit undesirable algae growth. They also recommend adding potassium so that the plants may better utilize the phosphorus directly (potassium as a cofactor). What are your thoughts on these topics?
