I know you posted back in 2010 but great info man! one thing i would suggest if you havent tried it already is actually use a dripper system from seedling up until you get a nice root structure developing past the bottom of the rock wool cube. this will help keep your cubes from getting over saturated and slowing down your seedlings. then once them roots are banging, switch it up to your EB and Flow system. either way, awesome how you shared your info along with your results. hope your still keeping things pushin! piece out smoky
