How H4W Works
Ancient Wisdom, Verifiable Results
Phyto-remediation is an ancient technique for cleaning and filtering water.

TRIAL AND ERROR YIELDS RESULTS
Hemp4Water® began researching the viability of hemp plants as a bio-remediator after the passage of the 2014 federal Farm Bill allowing hemp research. Tennessee was the home of our first test.
Hemp4Water® partnered with South Florida State College after the passage of the Florida Hemp Research Bill in 2018. Together Hemp4Water® and South Florida State College verified the efficacy of hemp in the absorption of phosphates and nitrates in water.
Not all hemp plants are created equal.
Hemp4Water®, working with researchers and plant experts, developed cultivars of Hemp specifically bred to flourish with wet feet.
Our proprietary cultivars of hemp love phosphorus.
Intelligent By DesignIt all starts with a known total managed daily load (TMDL). Once you provide us with a current TMDL our research team can establish a plan for your body of water! Then we can go to work cleaning your water!

Established Baseline
Our calculations are based on your unique TMDLs. Research led by Dr. Kate Calvin established the amount of phosphorus and nitrogen each of our proprietary hemp plants will absorb each day.
Load Monitoring
Throughout the lifecycle of the project our team monitors the water quality, as well as analysing the plants being removed for bio-hazards that may be collecting in the roots
Mat Deployment
Your TMDL determines the square footage of mats. Custom mats are loaded with hemp plant in the form of plugs. These plugs grow into tall, reedy plants that bear little resemblance to ‘Cannabis’.
Servicing
Mats are secured off shore to prevent mischief. These mats are periodically harvested and new plugs planted to maintain optimal levels of nutrient absorption.
Mat coverage is based upon the needs of each individual body of fresh water.

MORE ABOUT THE MATS
SURFACE DENSITY
Simple Math. With an established TMDL it is simple math to determine the number of plants needed to meet your timetable.
CONFIGURATION
Mat placement is engineered to minimize other uses of the water body and maximize the nutrient uptake potential.
SECURITY
Remote monitoring notifies the team if there is tampering or if the mat cluster becomes dislodged. Our biggest threat thus far has been alligators seeking a sunny spot.
