dude, ive read every piece of paper that came with the system, and ive been researching plenty. Ive asked A question that I could not find the answer to. Roseman im pretty sure it was your BIG Bubbleponics thread in the beggining where you stated to mix half of the nutes and poor some of it on the rock wool cubes. You must be mistaken. I am a forum NOOB so here is the quote from your thread.
"Now get a one gallon jug, and mix half the GROW nutes in it, and half the micro nutes, in warm water and stir it and stir it. Drain it through a tea strainer to catch any undisolved little rocks or clumps. Now pour some of it into each cup or cube, just enough to wet the cubes. If you over soak them, they can possible colapse and you don't want that now. If they colapse later,that is OK."
