The Science-Backed Benefits of Coco Substrate for Cannabis
In the competitive world of commercial cannabis, every inch of growth counts. While genetics, lighting, nutrients, and climate control are paramount, a solid growing substrate should not be undervalued in cannabis cultivation. At Rx Green Technologies, we believe the foundation of your grow matters, both literally and scientifically
Our Clean Coco Coir is an efficient, soilless cannabis growing medium. Whether your gardens are indoors, outdoors, or in greenhouses, Clean Coco Coir gives you the ability to cultivate confidently and with consistency.
What Is Coco Substrate and Why Does It Matter For Cannabis?
Coco is a sustainable cannabis growing medium that is made from coconut husks. Compared to traditional soil, it’s great at maintaining optimal water-air balance while promoting root oxygenation and nutrient uptake. It’s porous, which helps prevent waterlogging and root diseases.
Buffering (cleaning) high-sodium coconut husks reduces salinity, which is crucial to create ideal growing conditions. That’s why our coco substrate undergoes rigorous buffering and quality checks to ensure low salinity, ideal pH levels, and high cation exchange capacity (CEC).
What Makes Clean Coco Coir Stand Out?
These are a few reasons why clean Coco Coir is worth considering for your indoor or outdoor cannabis grow:
- Optimized Electrical Conductivity (EC). Clean Coco balances EC to support efficient nutrient uptake and avoid salt stress for plants.
- Superior CEC & Low Salts. Lab tests show our Clean Coco has a higher CEC (32 vs. 24) and significantly lower sodium (23 vs. 82) than a competitor product, which translates to more available nutrients and less toxicity.
- Vertically-Integrated, Lab-Tested. From husk to harvest, our products are lab tested to ensure they are free from contaminants, is consistent in quality, and is effective for cannabis.
We run trials on every aspect of cannabis product performance, delivering data-driven insights that help you optimize your plants’ potential using our solutions.
What Our Internal Study Revealed
The type of coco substrate you use also matters. These are the results from our proprietary trial, comparing Clean Coco Coir to a leading coco competitor:
| Metric | Clean Coco Coir | Competitor |
| Stem Diameter | Statistically greater | Lower |
| Yield (dry buds) | Higher per plant | Lower |
| THC Potency | Significantly increased | Lower |
Our study demonstrated that cannabis grown in Clean Coco produced thicker stems, heavier yields, and stronger THC potency, all under identical grow conditions. It’s also important to note that there was no significant difference in height or canopy.

- 29% Higher Yield in Coco-Based Substrate – One University of Guelph study showed that cannabis grown in coir-based substrates delivered 29% greater floral dry weight than other substrates and increased flower yield by 11%.
- Biostimulants and Coir Synergy – Another study found that adding biostimulants to coco fiber increased flower yields by 16% and that coco fiber enhanced root architecture, cannabinoid, and terpene concentration per gram of flower.
Why Coco Substrate Statistics Matter for Your Grow Operation
Understanding the science behind your substrate isn’t just interesting; it directly impacts your bottom line. Here’s why it matters for your grow operation:
Maximize Yield & Potency
Both independent and proprietary data show that coco substrate can boost yield and THC levels compared to other growing substrates.
Consistent & Predictable Performance
Coco’s high CEC and stable EC mean growers can anticipate reliable nutrient uptake, which reduces plant stress and variability in yield.
Disease Resistance & Oxygenation
This substrate balances moisture and air all the way at the root level, which helps prevent rot and promotes healthier, more resilient root systems.
