I use an ebb and flow system 10 5" net pots fill with hydroton. Plants look great but I noticed th roots are coming out the bottom of pots and laying in the left over water that doesn't drain, abou1 1" or so. The tray is not filled with hydroton just the net pots. Is this ok the roots constantly being in the water???? thanxs for the advice
yes, your plant's roots will spread out all over the place. Is your table covered (i.e. are the roots in a dark place)? In a DWC hydro setup, the roots are all in the water.
