Awesome thanksYea I used 5 gallons of RO ph'd water to 5.5 and let it sit overnight. The package said 7 gallons but 5 was perfect it wasent soggy or anything it was fluffy and airy like I wanted for mixing in the perilite. I do a 60/40 or 50/50 coco/perilite with handful of expanded clay balls mixed in the bottom of the pot for added drainage.
