Plagron Coco 50 l — Double-Buffered RHP-Certified Coconut Substrate for Maximum Yield
Photosynthetic efficiency starts at the root zone. Plagron Coco 50 l delivers a clean, inert growing medium that gives you full control over your plant's nutrition from day one. Part of the Plagron substrate range, this coco stands apart thanks to its double-rinsing and buffering process — a production standard unmatched by comparable products on the market.
Technical Specifications and Key Advantages
The double-buffering process removes all unwanted salts and locks in a guaranteed EC below 0.2 mS/cm (1:1.5 dilution) with a stable pH band of 5.8–6.8. This wide pH buffer means minor solution fluctuations won't impact nutrient uptake — a critical advantage in high-frequency feeding schedules. RHP certification provides third-party verification of quality standards and sustainable sourcing.
- Double-rinsed and buffered: zero residual salts, guaranteed low EC, clean substrate from day one.
- RHP-certified: internationally recognised quality mark for coco substrates.
- Pathogen-free, sand-free: ready to use straight from the bag without any pre-treatment.
- High water and oxygen retention: reduced irrigation frequency with optimal root-zone oxygen levels.
How to Use Plagron Coco 50 l
Fill your pots directly from the bag — no pre-soaking, no flushing required. Start feeding immediately from day one with Plagron Cocos A&B, the mineral base nutrient developed specifically for buffered coconut substrates. Dial in your nutrient solution pH between 5.5 and 6.0 for peak absorption. The light, airy coco structure promotes rapid and intensive rooting, compressing the vegetative phase and setting the stage for productive flowering.
Reuse and System Compatibility
Plagron Coco is compatible with pot cultivation, recirculating systems, and run-to-waste setups. After harvest, it can be reused as a soil improver or, if properly flushed with an enzyme solution, recycled for a subsequent grow. Flushing removes accumulated salts and accelerates the breakdown of dead root residues. Replace the substrate after six months of intensive use for consistent performance. For growers wanting to boost drainage further, combine with Plagron Perlite or explore the compact Plagron Coco Brix format.
Order Plagron Coco 50 l today and benefit from fast shipping across Belgium. Belgian growers trust Plagron's precision-manufactured substrates to deliver repeatable, data-driven results run after run.
Does Plagron Coco 50 l need to be rinsed before use?
No pre-rinsing is required. Plagron Coco has already been double-rinsed and buffered to the highest industry standards. Simply fill your pots and start feeding with Cocos A&B from day one. This saves time and eliminates the risk of inconsistent pre-treatment results.
What are the EC and pH values of Plagron Coco 50 l?
Plagron Coco has a guaranteed EC below 0.2 mS/cm (1:1.5) and a stable pH range of 5.8–6.8. The ultra-low starting EC prevents calcium deficiency and ensures that Cocos A&B nutrients are absorbed at maximum efficiency throughout both the grow and flowering phases.
Can Plagron Coco 50 l be reused for a second grow?
Yes, under the right conditions. After a successful harvest, flush the substrate with enzymes dissolved in water to remove salt build-up and break down dead root material. After a poor harvest or six months of continuous use, replacing the substrate is strongly recommended. Used coco works excellently as a soil improver in outdoor or garden settings.
Which nutrients work best with Plagron Coco 50 l?
Plagron Cocos A&B is the purpose-built mineral base nutrient for this substrate. Because coco is an inert medium with no inherent nutrient content, directly absorbable mineral nutrients are required from day one. Plagron additives complement the base feed and are designed to maximise yield when used alongside Cocos A&B on a coco-specific grow schedule.
