My understanding of hydroponics is to have a nutrient rich solution flowing through an inert media that the plants are rooted in, now with CPs they take in very little to no nutrients through their roots and peat and sand are pretty much inert so a tray system would qualify as a primitive hydroponic system!
The soil mix that I suggested and RP modified could have the last organic ingredient removed if another suitable, non organic, source of acidity could be provided without leaving residual salts in the soil upon evaporation. Any suggestions?
