I'm running mine in coco.

My latest technique is germinate in 3 "coco to 6" coco pot to 6" net pot in DWC. I waited for the 6" pot to get plenty of roots growing up the edge before I move to the final 6" net. This allows the roots to bind the coco so none drops off into the DWX rez. Aeration through 1 each 6" air disk per bucket. Each rez looks like a boiling bucket of water, which is what I was aiming for. That's plent of nutes hitting coco without erosion and contamination of the rez. There's the odd speckle in there, but it works out fine for my application.

The tallest of the run is 44" inches with heavy fruiting and the plant is more than stable. The ph gradually raises as rez is used up and nuetrients have been uptaked but no practical ph difference due to medium.
