The Problem With Hyperaccumulators: How to tell if you have contaminants in your Cannabis product.
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 metal 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.

How can you tell if you have heavy metal contaminants in your final cannabis product?
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 MJ™ water soluble cannabis fertilizers line. When cannabis growers are aware of heavy metal levels in their crop inputs, they can anticipate potential levels within their buds.

Plant-Prod is pleased to announce a new addition to the Plant-Prod MJ product line, designed specifically for the cannabis industry – Plant-Prod MJ Spike (CaMg).
This new Spike (CaMg) fertilizer is made of exclusively chelated calcium (Ca) and chelated magnesium (Mg). Cannabis requires significant levels of Ca and Mg throughout the production cycle, especially during flowering and bud formation to ensure maximum yield.
The fact that this product is formulated with only chelates makes it truly unique. Chelated nutrients are far more accessible to plants and are immediately available to the roots. Most forms of Ca and Mg are either in sulfate, chloride or nitrate forms. Due to the high amount of Ca and Mg required, there is a greater chance of salt damage when using sulfate and chloride sources. In soilless media, many sulphate and chloride based nutrients are lost through leaching before they can become available to plants. When in the nitrate form, more nitrogen is provided to the system, compromising yield potential by confusing the cannabis plant. By adding excessive nitrogen at bud and flowering stages, plants will begin to grow vegetatively, shifting the plant’s focus from flowering to leaf and stem growth. Reducing overall yields.
Plant-Prod MJ Spike (CaMg) is formulated to give you the perfect ratio that cannabis plants need, 2 parts Ca to 1 part Mg, providing precise nutrition for maximum results.
Note that this product is not compatible with other Plant-Prod MJTM products. Please consult your Plant-Prod sales representative.

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.”
