These Grow Additives ARE NOT Required! (But Increase Yield)

In this episode of The Dude Grows Show, host Scotty and guest Granbo dive deep into the world of biostimulants—products that don't provide nutrients but instead stimulate plant growth and resilience. They clarify that while plants only need 17 essential nutrients (NPK and micronutrients), biostimulants like kelp, chitosan, trichoderma, fulvic acid, and microbial inoculants can significantly enhance yield, stress resistance, and terpene production. The hosts emphasize that biostimulants are not 'plant food' but rather tools that trigger natural plant responses—such as hormone production, defense mechanisms, and improved nutrient uptake. They break down key biostimulants, highlighting kelp’s proven benefits, chitosan’s role in systemic resistance, and fulvic acid’s ability to boost nutrient efficiency. The duo stresses the importance of A/B testing with new products, using baseline nutrient regimens before introducing additives. They also reflect on the cannabis community’s innovation, the challenges of regulation, and the irony of anti-drug funding in Florida. The episode closes with a lighthearted look at unnecessary grow gadgets and a shoutout to the DGC Cup and the growing community.
