I have 2 girls in supersoil, and turned the res on from the jump.
Cracked to a tail in water, off into a rapid rooter, rapid rooter into the spring pot (with humidity dome) the day after coming up. Turned on the res.
Rolling a Blueberry Muffin (Humboldt) and a GDP (Ken’s) for this and both were to the post edge in just 17 days.
50/50 mix of Mother Earth and Coast of Maine Platinum soils, then added a little kelp, myco, and some worm castings.
Mixed the bottom 1/3 with concentrated supersoil, and off we went. Girls seem to love the hell out of it.
Last coco run is finishing, maybe 3 more weeks or so, and then it’s all supersoil and res on at start from there.
