Thanks for the quick reply! it's not a true hydro grow it's a coco / perlite grow. if that matters.
Coco/perlite is a form of hydro! That would be like saying rockwool isn't true hydro
Anyways, good afternoon PW! I'm catching up at the moment
I've seen this debated before and it's somewhat of a fine line and matter of perspective. Some people only consider it to be hydro only if there are pumps and reservoirs involved. I would argue that it's "passive hydro" vs. "active hydro" and others would simply consider it a "soil-less mix". Are all soil-less mixes hydro? I don't know, I guess it's a matter of perspective!
