How does this super soil mix look? Amended at 2tbsp per gallon in 10 gallons of 70% ProMixBX, 15% Perlite, and 15% Worm Castings. (60tsp = 20tbsp) (3tsp = 1tbsp)
use the rule of 3rds here, Id personally go with 50% promix 20% vermiculite as it has much more benefits than perlite has, and the rest worm castings and kelp meal
