Rock dust?

What exactly does rock dust do?

Well technically it just exists as a form of whatever rock it is form from, just in a physical state of whatever dust is classified as, scientifically. I really need to work on my english grammer, sorry. But, to answer your question I would need to write a short story explaining what soil is. Without doing that, rock dust would probably fall under the classification of sand, but this is all depending upon the granular structure of the rock dust. Sand grains are the largest soil particles ( if you have larger particles they are considered part of the soils substructure) ranging drom .05 to 2mm. Dont get out your micrometer yet. I make a base of either volcanic rock, crushed volcanic rock(not to dust), or pea gravel to make a good base for drainage, and a rock or two always makes its way into the upper soil horizon. Go grab a few book, might be available at your local library. They will do more than answer any questions you have, all canna growing is, is a very specifically specialized area of biology and horticulture. Very special! Like the kind of special that makes me think twice aboot spelling.

Are you asking what Perilite is, some call that rock dust...
Or what it does?
It helps with soil drainage... gives roots oxygen in pockets, in the soil, and helps with drainage...
I mix 12.5% Perilite, and 12.5 % Vermiculite into my soil grows....

Rock dust glacial or basalt provides all the minerals and macro minerals that plants need that other nutes don't have. Rock dust is also a nutrient accumulator. Fungi also grabs on to phosphates in rock dust.

I top dress occasionally with glacial rock dust. Il also use it when in trying to make a fungi dominate tea

Thanks. I thought it had to do w/ trace minerals. I heard it can help with flavor and aroma. I was researching a little bit on the 16 essential elements to make plants grow and what their function is. The info I came across was interesting. I was trying to relay some to here and see what I can stir up.
