They look really nice Brussels; you are using only co-co for the substrate? Nothing else because I think I read that earlier but it is a little difficult to believe at this point. Do you think you use more or less nutrients with the co-co versus the cubes? Do you think the co-co could survive organics like compost tea with that much watering? I guess that is a tough one to determine. I read that it is mildew resistant and can be re-used a couple of times.
