When you introduce the powerful beneficial fungi in Piranha to your root zone, you'll experience many amazing benefits. First, the fungi will help expand the effective surface area of your plant roots and their cumulative length by up to 75%. Scientific tests have shown this can help your crops obtain as much as 86% more nitrogen, 234% more phosphorous, and 75% more potassium than growing without these fungi. And this, of course, translates directly into heightened vegetative growth, greater leaf area, more bud production, better flower structure, and increased weight! Plus, these fungi secrete growth and bloom co-factors directly into your plants, further increasing yields. Lastly, Piranha 's fungal species are proven bio-control agents that seek and destroy harmful pathogens, including molds, while strengthening crop resistance to stress.
