I am using a mix of M3, DairyDoo, Coco and Perlite.
Originally started with the dairydoo veg but quickly realized it retained water forever....so I mixed in the leftover M3 from first round, some coco and perlite. Got some pot stands- and problem solved.
For suppliments, I am using advanced nutrients B-52, Rhino skin, Overdrive, big bud, bud candy, and Micro. I am also using cal-mag and unsulphered molassis.
