I had to sink a couple of the plants lower into their pots because the growplugs werent wicking enough water up through the L.E.C.A., and they were drying out. I have a feeling my heirloom tomato is slightly stunted because of it.
Is it possible for the growplugs to absorb too much moisture?
RupertofOZ, is there a notable difference between hydroponic "ebb & flow", and "flood & drain aquaponics"? I was under the assumption they were the same principles and techniques, just different nutrient sources.
I will get a test kit, and go from there . Thanks for your time guys.
