I wouldn’t put any more then 30%. I tried once going 50/50 and I ran into problems I’m positive we’re ph related.Yes I understand that. What I am asking is at which point by adding aeration does it become a “coco” or “hydro” grow. Like what is the tipping point of the ratio of say coco to soil?
Does it need to be 100% coco to use the lower pH or can it be 70/30 and still use the soil range?
