I love beating a dead horse, so I decided to perform a 3 Factor DOE on soil components.
First off, a the reasoning... I am having a difficult time finding certain soil components like pumice, smaller lava stone, haydite etc. I have called and searched like crazy
I also have a difficult time driving a long way (several hours) just for soil. I wouldn't mind if I could also view/buy trees, but that is another story.
Secondly, I can't afford Akadama. I have also read that things like hard fired clay, Akadama and the like do not survive the freeze/thaw cycles. It is simply something that I don't want to worry about (the OCD in me will drive me crazy)!
So, I have 6 soil components, 2 for each category.
Grit


Porous

This is Zeolite. Supposedly very absorbent, but the grain size is small.

Found a local supplier of grow stone. Saves on shipping!
Organic

Just something that I picked up at Lowes

Purchased at Home Depot
More to come on the experiment setup and results... Wife needs the computer
