Coco is hydro no matter what method you use to irrigate it's hydro. Hand feeding? then it's passive hydro. Auto-feeding method? Then it's active hydro. Don't matter wether you feed from top or bottom.
It's not a soilless mix if it's pure coco, a soilless mix has nutes in it and coco doesn't which is why it's a hydro medium.
I'd say you were a coco grower.![]()
