Emerald Cup 'Soil of the Year’

In 2015 the Emerald Cup named Big Rootz® ‘soil of the year’. Big Rootz® is currently used in many of northern California’s marijuana collectives and is outperforming its competitors. Big Rootz® has been a focal point in cannabis cultural media such as skunk magazine and is featured by MendoDope in their popular grow videos.

Big Rootz® is carefully formulated for professional growers, yet it’s so easy to use that even novice gardeners can achieve growing success. Use it for indoor grows or outdoor greenhouses, or add it to existing soil.
