What Nobody Is Telling You About Heavy Metals in Cannabis
Pay close attention, because this little-known fact can change everything about the way you grow. Cannabis is an accumulator plant, which means it takes in everything from the soil or growing medium — without discriminating between the good and the bad. Not only does that mean you have to feed your plants the safest nutrients possible, but that you also need to be aware of toxic, heavy metals that accumulate between seed and senescence.
After dedicating weeks on end toward achieving the perfect harvest, the last thing you want is to risk the safety of your end product. The stakes are high, and it’s vital that patients who rely on healing cannabis are consuming products that are void of dangerous toxicities from heavy metals
But first, what are heavy metals? They’re conventionally defined as elements with metallic or metalloid properties and an atomic number greater than 20. However, that doesn’t mean all heavy metals are toxic. In fact, some — including iron, copper, and zinc — act as valuable micronutrients for plants when administered in low doses. These heavy metals can become toxic when taken in excess, while other heavy metals — such as lead, arsenic, nickel, and mercury — are unconditionally toxic and/or carcinogenic.
Where Does Cannabis Contamination Come From?
We already know that the risks are high with such an incredible accumulator plant. In order to avoid these risks and keep your cannabis safe, let’s delve a little deeper and look at the different sources of contamination.
Multiple factors can be responsible for the uptake of heavy metals. Root zones can absorb contaminants from the soil; other growing media and some nutrients can also be responsible for toxic elements that creep into the final bud. The specific strain of cannabis, pH levels at harvest, chelated agents, environmental conditions, water sources, and the unique chemical properties of each metal also come into play as primary uptake mechanisms of these contaminants.
Ultimately, it’s crucial to understand that every step in the growing process ultimately affects the level of crop contamination.
WARNING: Not All Fertilizers Flush Equally
It’s a simple equation: The cleaner your buds are, the more they are worth. Cannabis growers experience an unparalleled sense of satisfaction when the quality of their final product reflects their extreme dedication to achieving safe, potent, and flavorful flower.
But beware: Not all fertilizers are created equally.
When it comes to plant nutrients, there’s no one-size-fits-all solution. While a generic fertilizer may seem like a sensible, cost-effective answer at first, the risk of contamination is too high for your plants — and ultimately, your end consumer. The fact is, cannabis requires specific ratios of essential nutrients that increase yield and cannabinoid potency, without compromising the crop by introducing toxic heavy metals.
So what should you look for when purchasing a fertilizer that’s free of contaminants?
A good micronutrient fertilizer consists of high-quality salts and chelates, and will protect the plant from excessive uptake of toxic heavy metals. Whether it’s synthetic or organic, each chelator must be free from toxic heavy metal contamination. At the end of the day, it’s a matter of purity. The best fertilizer companies regularly check their chelators before implementing them into their nutrient solutions.
The Main Contamination Culprit May Surprise You
A shocking reality is that phosphorus — an essential primary plant nutrient — is the primary potential source for heavy metal contamination in plants. This is largely because phosphate ions form chelates with heavy metals, and then carry those toxic metals into the plant. And that’s not all… Raw phosphates mined around the world are often laden with hidden danger: They contain substantial amounts of toxic contaminants that were captured millions of years ago when the deposits first formed.
A team of cannabis-specific Ph.D. scientists at Advanced Nutrients conducted hundreds of experiments to understand just how much phosphorus cannabis needs to thrive… and when the nutrient began breaching the danger zone of toxicity.
The result was a game-changing discovery in plant science. Previously, the growing community abided by a common misconception that they should feed their plants additional phosphorus for enhanced blooming. But through rigorous testing, Advanced Nutrients’ scientists unlocked a radical conclusion: Plants actually recycle phosphorus, so they need only low doses of the nutrient — enough to support crucial functions without risking heavy metal contamination.
PRO TIP: The Only Plant Flusher You Need
Fortunately, there is a simple, yet extremely effective, process for getting cleaner, safer buds right before harvest. Armed with a low-phosphorus policy, Advanced Nutrients’ team of more than 30 scientists set out to create the ultimate solution for flushing plants of unwanted contaminants that accumulate as they age. The result is Flawless Finish, a premium product that is popular among top growers who consistently yield high-value harvests.
Flawless Finish has been specifically designed and tested to provide a complete, value-enhancing cleansing of the cannabis plant. And the benefits of this solution go beyond just flushing toxic heavy metals out of your bud. Growers report crops with a sweeter aroma, as well as the preservation of the essential oils and resins that yield the highly potent end product you’ve worked so hard to achieve. If you’ve ever wanted to experience love at first taste, this product is essential to include in your arsenal of premium cannabis nutrient solutions.
