How often should I water with rockwool & ebb & flow?

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

Yes very good thread. I been getting root rot with 6 inch rockwool. I was only feeding once a day. now i only feed once or sometime twice a week. and for bigger plant and mid flowering once a day. 6 in rockwool hold alot of water. when plant just got transplant to 6inch cube from 1.5 cube you will need yo soak once. let it dry out for about 7 days and you should see new root growing out. should spray the leave with light veg nutes.
