I'm not completely happy with hydroton as a medium in my net pots. I only allow the base of the pot to touch the water, until there are good roots below, then I lower the res content to in inch below the pots. I'm thinking that placing hydroton in the bottom of the pots, then filling with coco would give the plants a more stable support. I would not be feeding at lll through the medium. Similar to what your doing i think. Do you feel this would work?
To me. . A user of hydroton I think that would work as a more stable base for the bigger plants. . I know I've had to tie my big girls down when they started to lean from the weight of the upper half.. And one fell over once. . With my micro and scrog. . The screen pretty much stabilizes the plant where I don't have that problem. . If that's what you meant
