White Widow 1

The mycorrhizae fungi in Humboldt Nutrients White Widow can help provide plant roots with greater access to water and nutrients in the soil. Mycorrhizal inoculants are crucial to sustaining a healthy, expansive root zone.

With White Widow the speed and aggressiveness of your plant’s root development can be increased. It is common to see large, furry, bright white roots shooting out of the bottom of containers only a week after transplanting with this mycorrhizal powder.
