Top 4 Reasons to Grow Cannabis In Coco Coir- RIOCOCO


An organic and naturally occurring product manufactured from mature coconut husks, coir substrate (or coco coir) is mainly used as a growing media or soilless substrate for horticulture applications. Because it is a coarse material obtained from the husk surrounding the coconut seed, coco coir is renewable and environment-friendly. Also, the coir substrate is suitable for improving plant yield and quality. The growing medium is favored by many gardeners around the world, as it is appropriate for growing different kinds of plants in an easy fast way.

Top 4 Reasons to Grow Plants in Coco Coir

Nowadays, you can find numerous mediums other than organic soil to grow cannabis. Unlike stonewool, perlite, or peat, the unique properties of a coir substrate make it the ideal choice for growing high-quality cannabis. Keep reading this article for the top reasons for growing cannabis in coco coir:

Reason #1: Optimum pH

Unlike other mediums, coconut coir has a neutral pH level which, providing optimum uptake of nutrients. Hydroponically grown cannabis requires a pH of 5.8 – 6.3, RIOCOCO has a naturally-occurring pH of 5.5 – 6.5. Other mediums require a continuous monitoring of rhizosphere pH conditions as their low CEC allows for minimal buffering and significant pH swings. However, with RIOCOCO coconut coir, the naturally-occurring high CEC provides the root zone pH stability necessary for consistent pH levels and nutrient uptake.

Reason #2: Drainage

The moisture retention capacity of  RIOCOCO coconut coir is very high, and so is it’s air-filled porosity. Since unbuffered coir breaks down slowly, it maintains air pockets in the root zone allowing excess moisture to drain away from plant roots. Lower quality coco coir substrates have high dust levels, slowing drainage and diminishing the availability of oxygen to roots. At the same time, in order to prevent against wilting, the coir itself holds onto enough moisture so that its retention curve plateaus at the perfect point for generative crop steering. This dual drainage and retention properties of coco coir allow it to improve irrigation management.

Reason #3: Consistent Quality

The best thing about coco coir is that it comes sans nutrients – that is, unbuffered. Most stages of cannabis growth require high levels of nutrients, especially when cultivated under modern high-par lighting. At the end of the flowering cycle, though, growers need to flush the excess nutrients from the medium, allowing for the improved taste and resin production from plant senescence.  Since RIOCOCO coconut coir has a uniquely high CEC it responds to changes in required EC quickly and efficiently.

Reason #4: Sustainability

Peat bogs where peat moss-based mediums are sourced take centuries to regrow – if ever. Coal-burning factories, from which stonewool is produced, emit Ammonia and Formaldehyde.   On the other hand, coco coir is completely sustainable renewable resource:  a natural byproduct of coconut harvests produced annually by coconut trees. 

RIOCOCOs compostable grow bags keep plastic pots out of landfills where they take centuries to fully break down. RIOCOCO’s ECOPURE grow bags are made of a cutting-edge biodegradable polymer, breaking down in two years.
