Question for Tapla - zeolite in Gritty Mix?
I am one of the early adopters of Gritty Mix in Australia. Over 100 pots now and all going very well.
Many of the bonsai growers here use well aerated mixes containing materials like Turface, diatomite, perlite, grit etc.
One of the frequently used materials is zeolite, it is readily available and in perfect 1/8" size. It has a very high cation exchange and hence retains nutrients.
I was wondering if 1/2 or 2/3 of the grit in Gritty Mix could be replaced with zeolite?
