I used pulverized ACRB, Cyb/CTM´s "Max Ion tek" and i got a product looking like your "After" pictures with no re-x.
I can really recommend it, fantastic results.
I wonder how my product will look like if i try clean it.
I might try your cleanup procedure.
Good work.
Growing active and sacred plants and mushrooms is fun.
Chemistry and technology is fun.
Anger, violence and restricting rules are NO fun...
