(EPISODE 9)Everyone talks genetics. Everyone talks nutrients. But almost nobody is talking about the one variable that changes everything inside the room — spectrum tuning.In this episode of the MangoTech Podcast, host Alex Villegas sits down with Josh Barker, one of the sharpest cultivation minds in the game, to break down what spectrum tuning really means for growers who care about resin, yield, and consistency.This isn’t a sales pitch. It’s raw, straight grow-room talk:🌱 White light – the backbone that drives bulk canopy growth.🌱 Deep Red – the engine behind flower stacking, density, and bulking phases.🌱 Far Red – how to manipulate stretch, trigger the Emerson effect, and unlock timing advantages.🌱 UV – why this “last channel” is the secret weapon for trichomes, oils, and defensive resin production.Josh and Alex dig into the recipes pros are testing right now:How spectrum ratios change depending on cultivar.Why certain strains demand more far red or less UV.The balance between “yield vs quality” when tuning.Real examples of how dialing light correctly added 20–30% resin output.And they don’t hold back on the controversy either — calling out how most growers underuse their lights, how companies mislead people with wattage numbers, and why spectrum tuning is the difference between mid shelf and true top shelf.This is the kind of conversation you don’t hear in glossy ads or shallow grow reviews. It’s the inside look at how spectrum tuning is becoming the Formula 1 of cannabis cultivation.If you’re serious about growing — not just watching plants survive, but watching them perform — you need to hear this episode.👉 Tune in now. Take notes. Start experimenting.Because once you understand spectrum tuning, you’ll never look at light the same again.
