Truckn - How are those clay pellets treating your system? I just posted under "couple of hydro questions" if you want to read the whole deal, but basically the hydroton seems to be messing up my whole system. It's dirty - leaving grit everywhere and coloring the water. Am I missing something or is this just a really dirty medium?
In answer to your post - I'm running my first hydro ebb and flow w/ hydoton on Anvanced Nutrient's Micro, Grow, and Bloom at about 1/2 label strength at first because my vegging plants are small, have experienced some heavy stress lately, and because they were yellowing at full label strength for veg state. I'll post how it goes as it goes..
