Plants with the capability of accumulating heavy metals above concentrations that would typically cause harm or toxicity in plants are known as hyperaccumulators. Cannabis is a well-known hyperaccumulator with the ability to remove heavy metals contaminants from soils. This characteristic is desirable for soil remediation but troublesome when cannabis is grown for consumption.
If the nutrients you use are contaminated with heavy metals, your buds will be accumulating these heavy metals, exposing those who consume them.
We care about heavy metals just as much as you do
Licensed producers of cannabis are required to test their finished products for heavy metal contaminants. Plant-Prod® is pleased to make heavy metal analysis results available to growers for our Plant-Prod MJTM line. When growers are aware of heavy metal levels in their crop inputs, they can anticipate potential levels within their buds.
Outsourced analysis of heavy metal concentrations:
Plant-Prod has launched Plantex MJ Bloom water soluble fertilizer for large scale growers of medical marijuana. This formulation is designed specifically to maximize bud size, following the leaf growth phase.
“Many of the fertilizers targeted to growers in the past have been formulated with “secret” and “magic” ingredients but without a deep understanding of the accumulated science and experience of horticulturalists and agronomists,” states Plant-Prod’s General Manager. “Our 70 years of maximizing productivity of growers of high-value crops is proving invaluable to licensed growers of medical marijuana that require plant nutrition that is scientifically optimized, consistent and completely soluble.”
As with all high value crops the formulation should be adjusted to account for the characteristics of the irrigation water and growing medium. “Growers need to pick the best formulation for each growth stage of the crop. The first step is always to perform an analysis of the water and soil,” explains Plant-Prod’s Sales and Marketing Manager “Then the plant scientists in our dealer network will provide advice on how to optimize the formulations.”
