For clients that like to have huge planters I was thinking that Kitty Litter would be an excellent amendment to the potting soil... I first heard about it as 'Zeolite' Kitty Litter having excellent CEC and filtration capabilities... They no longer have zeolite on the kitty litter label, just the generic "Fuller's Earth" which can be any number of elements... Is it safe to assume that it is going to be fine as long as it is the natural extraction without added ingredients??? All Kitty Litter needs to be absorbent, so will function the same basic way in the pots,,, correct???
