[AUDIO only] Office Hours Ep. 153: Dosatron Deep Dive: Fertigation Truth from 25 Years in the Field

The guy who brought Dosatron into commercial cannabis is finally on the show — and he's not holding back.Chris Lungardin has spent 25 years in horticulture and 13+ at Dosatron USA, walking more commercial cannabis facilities than almost anyone in the industry. In this episode of AROYA Office Hours, Chris joins host and applied technology expert Jason Van Luven for a no-fluff breakdown of how fertigation equipment actually performs inside real grow rooms — and where most operators get it wrong.You'll learn why direct injection isn't always the right call for precision irrigation, how batch tanks changed the game for centralized nutrient delivery, and what happens to your EC and pH when your Dosatron sits idle overnight. Chris also covers the evolution of the "nutrient delivery system" concept he pioneered, how to think about water treatment and sanitation inline, and the honest tradeoffs between water-powered dosing and electronic injection systems for operations at scale.If your grow is making decisions about fertigation strategy — whether you're running Dosatrons today, evaluating a centralized system, or just trying to understand what's causing inconsistency room to room — this conversation is required listening.Share this episode with your head grower or cultivation director.
