Frank says the full system works better for him, and you know what, I believe him. He's only set up almost a dozen tanks using ADA substrate and presumably has a pretty solid comparison point for with and without additives by this point.
Not making any comment on the additives.
It's as plain as day that you can't compare those two tanks root shots, to pass those off as proof is insulting.
Maybe if it were the reverse, and the hc had root growth like the hair grass and the hair grass also had root growth like hair grass always does...
If I put rocks under aquasoil and plant hair grass and then just use aquasoil in another tank and plant hc, and claim the rocks are why there is a dense mat of runners an roots in the hair grass tank, would that be okay with you, would you close your eyes and applaud?
