Thanks to all of you. It's great asking a question and hearing what you want to hear.

Pimpjuice: Are you the 10KW, 90 bato pimpjuice?
Prepping for my next run, I just recently expanded 6 bales of coco, one at a time, then moved to my garage for mixing, as 3 were chips and 3 were pith.
As I was doing it, I told myself it was the last time. At the time, I was thinking hydroton, but perlite is easier to come by, and much lighter. I know that coco can be reused, and I have before, but I still think the perlite may perform better.
