Cost $5.27/Acre: First time uses apply at 7 oz. per acre in at least 20-gallons of water or agrichemical mixture. Apply before final disc or seeding with till-less growing. Then, apply 3 more times at 5 oz. per acre, at even intervals stopping 1-week before harvest.


How it Works: Natural plants and synthetic fertilizers are incompatible. It is difficult for plants to absorb minerals such as iron, zinc, and synthetic fertilizers. In some cases, plants absorb as little as 30% of applied fertilizers and minerals. As much as 70% of applied fertilizers remain unused. After multiple years of synthetic chemical applications, soils are bound up with synthetic contaminants. Hair roots are unable to penetrate the soil and absorb minerals, moisture, inorganic nutrients, or oxygen. Applying additional fertilizers does not help and increases pollution. Plants remain malnourished, and yields are diminished. GreenSafe™ Plant Amendment uses the latest advances in nano/colloidal technology to break up bound up soil to increase uptake of nutrients and moisture.

    Cost: The recommended 5-oz./acre application cost varies from $4.88 to $4.31 per acre, depending upon purchase volumes.  3 applications are typical for an outdoor cannabis harvest cycle.


    Value: The yield increase was 122.8% for oil and 158.4% for biomass in a controlled outdoor test.  This after a savings of $30/acre or more from reduced fertilizer requirement. See the full report at the Tech and Testimonials tab.
