Can I do without a biofilter to keep living microorganisms in a hydroponic system (Trichoderma for bioponics or Trikologic S)?


To stay alive, microorganisms need a porous, moist and oxygenated environment in order for them to colonise. After a number of tests, we recommend that you make a mixture of 70% clay pebbles and 30% coco fibre.
However, in aero-hydroponics, the use of a biofilter is compulsory as the total volume of substrate is insufficient
