i can vouch for earth juice biorighteous an recharge work well with any rock wool. best rooting combo i have ever used beside cannas rhizotonic.
using the biorighteous an recharge produces explosive roots when they get under way. i also use dip-n-grow to start. ph 5.5, couple hundred ppm of food
roots lift up an twist the gro blocks
these blocks where all symmetrically placed in the the clone tray. 15-18 a tray. rows of 3. they all moved. look how crooked the roots made the blocks in the back
