Are Your Nutrients Safe For Coco Coir?

Since ancient times, the coconut tree has been called the “Tree of Life” for its powerful healing properties and practical uses. In fact, a study of the coconut tree reveals an almost supernatural evolution into what is now one of the most useful species of plant life known to man.

Between its medium chain fatty acids, lauric acid in particular, and its antimicrobial, anti-bacterial, and anti-fungal ingredients, the coconut fruit itself has proven to be an unusual but incredibly potent immune system booster in humans. Coconut oil has been used by Pacific Islanders and Asian cultures to effectively treat everything from skin conditions like eczema and psoriasis to the common flu virus, hepatitis C, and the measles.

And the coir from coconuts (the brown fibers that surround the outside of the shell of the nut which, surprisingly, are found to be swarming with all the beneficial nutrients found in the fruit itself) has been used for making brooms, rope, bindings to doormats, fishnets and even frames for housing.

The famous explorer Marco Polo even used coco coir to bind together planks for ship building.

And as you know, with a near perfect pH…

Coco Coir Is An Incredible Growing Medium For Hydroponics

And stable pH levels aren’t the only reason to choose this medium.

Coco Coir…

  • Is naturally aerated, helping roots to absorb the nutrients they need to grow into a robust and efficient network.
  • Has excellent water retention and drainage properties, fostering healthy plants and an oxygenated root zone.
  • Is a renewable and environmentally friendly resource.


There are a few things to know about this one-of-a-kind growing medium.

Without a Coco Coir Safe® Product, You Risk Nutrient Imbalances Destroying Your Crop

The fact is, if you’re not using nutrients designed for coco coir, you’ll not only be missing out on the gigantic yields you could be getting… But you’ll also run the risk of either poisoning or starving your crops!

Now, it’s true that calcium and magnesium both occur naturally in coco coir. But the amounts of each aren’t sufficient to feed your plants.

And not only that, calcium and magnesium both naturally bind to coco coir!

This means only the highest quality, chelated forms of magnesium and calcium (like the kinds used in Advanced Nutrients’ products) are able to succeed in a growing environment that uses coco coir.

Use inferior forms of either, and they’ll bind to the coir, leaving your plants hungry for these vital nutrients.

What’s more, iron also binds to coco coir, which means your plants could be left iron deficient, inhibiting their development.

And if your nutrients don’t use chelated magnesium, calcium, and iron, you’re missing out on better yields. (Many inferior brands will try to add dolomite lime as a quick-fix to supplement calcium and magnesium, but don’t be fooled… it’s not effective.)

It’s also true that if a hydroponics nutrient or biostimulant doesn’t account for the levels of potassium already present in coco coir, you risk potassium toxicity.

With that in mind, it’s very important to check whether the hydroponics nutrient products you’re buying are coco-coir safe, and account for any nutrient imbalances you may encounter when utilizing this growing medium.

Over time, components within the nutrients settle on the bottom of the bottle. When you pour a bottle without shaking it, you can potentially be pouring out an unbalanced solution. Shaking up the nutrient bottle ensures you are pouring the right blend into your reservoir, giving your crops the nutrition they need.

Usually, it’s not a problem. But some products are incompatible with each other and can damage your plants when they’re used together. For example, bloom boosters with high PK numbers or low-grade silica products can destabilize your nutrient mix and cause nutrient lockout.

Nutrient manufacturers design their products to be used with each other. In doing so, they include specific portions of each nutrient in each product, so crops receive the right nutrition through each stage of the grow cycle. When you stick with one manufacturer, you don’t have to worry about inadvertently destabilizing your nutrient mixture. One example of why you need to stick with only one manufacturer’s products is Advanced Nutrients’ pH Perfect line. These products are designed to keep your crops’ root zone within a specific pH range. When you use them alongside products from another manufacturer, we can’t guarantee your root zone will maintain its optimal pH level.

Advanced Nutrients has spent many thousands of man-hours developing a technology that automatically balances your pH for you — putting it in the “sweet spot” and holding it there for one week.

And the technology is so “smart” that it can account for many of the aforementioned variables in your grow room. Our proprietary pH buffering agents and stabilizing mechanisms became the foundation of a new system aptly called pH Perfect® Technology. Learn all about it here.
