By Plagron. If you've ever tried growing in coco coir without the right nutrients, you’ll know it’s a bit like trying to cook with a pan that hasn’t been oiled. Nothing sticks. Nothing works. Everything burns. But with Plagron Cocos A & B, suddenly you’re not just feeding your plants - you’re fuelling them with high-octane, mineral-based brilliance, built specifically for the quirks and perks of coco cultivation. Developed by seasoned Dutch growers who’ve done it all - from stealthy cupboard grows to industrial fruiting setups - this is nutrient science without the nonsense. For Professional Growers. Plagron Cocos A & B is a dual-component fertiliser formulated to match the entire life cycle of your plants, from tentative vegetative stages through to full-throttle flowering. Coco is inert - meaning it contains precisely no nutrients. That’s both a blessing and a curse. The blessing is that you’re in control. The curse is that you’d better know what you’re doing. Cocos A & B steps in here like a seasoned technician, delivering the exact blend of macro and micronutrients needed to build strong cell walls, rapid root systems, and lush, photosynthetically efficient foliage. Premium Nutrition. Premium Flavours. One of the standout features of Plagron Cocos A & B is its smart approach to nutrient delivery. It separates calcium and phosphorus into different bottles, not just for marketing flair, but to solve an actual chemical problem. When calcium and phosphorus meet too early in solution, they bind, precipitate, and become unusable to plants. By isolating them in Cocos A and B respectively, and diluting them when mixed, Plagron has eliminated this issue completely. You get more nutrition, more uptake, and less muck at the bottom of your tank. And no, it doesn’t crystallise either - so your pumps and drippers will thank you. For Craft Quality Plants. With its new formula, Cocos A & B offers visible results in just a few days. Plants take up nutrients faster, which leads to a surge in cell division, leaf development and structural strength. If you’re aiming for aggressive early veg growth or heavy fruiting later on, this isn’t just helpful - it’s critical. And it’s forgiving, too. The nutrients are absorbable across a wide pH range, which means your plants stay happy even if you’re a bit clumsy with the pH pen. It’s like nutrient insurance for indoor growers. Made By Dutch Growers. Coco coir itself is a beautiful thing. It drains well, aerates roots better than most substrates, and plays nicely with microbial life if you're into that sort of thing. But it does tend to hoard salts and requires consistent moisture. This is where Plagron Cocos A & B shines again. Use it with every watering, and you’ll maintain both hydration and nutrient availability, avoiding those nasty deficiencies that creep up when coco starts locking things away. Some Of The Best You Can Get. Application is straightforward. Shake the bottles, mix A and B in equal parts at up to 4ml per litre, and use it with every feed. Make sure you're getting a bit of runoff - 10 to 25% is ideal - to keep the coco clean and your EC levels steady. Available in 1, 5, 10 and 20 litre bottles, Plagron Cocos A & B slots seamlessly into any size setup, from hobbyist to high-output commercial rig. In short, Plagron Cocos A & B isn’t just another nutrient line. It’s an intelligently engineered solution to the unique challenges of coco growing. Easy to use, chemically stable, and brutally effective, it’s everything you need for green, explosive, healthy growth. Whether you're running a compact tent or a full-blown greenhouse, this is the base nutrient that makes your coco coir sing. Trustpilot
