After some good success is adjusting monstera to hydroponic now taking cuttings and seeing good benefits to my no3 levels I’m germinating some bell peppers and chilli peppers to also grow hydroponically in my fish tank so I’m making a makeshift attachment / box / pot for them to be more secure I the tank , I want to add a media for the roots one to stop the fish eating them and two just to stabilise the plant a little more was going to use plain old ceramic rings but would like to use coconut fibre , mistake ? Or is it sound for the fish and water
