Organic & Nitrogen Free.

Think of Biobizz Calmag as your plant’s personal trainer. It’s the 100% organic, nitrogen-free solution designed to correct calcium and magnesium deficiencies before they wreak havoc on your grow. Modern tap water can’t always be trusted to provide the right mineral balance—especially if you’re using soft water or a Reverse Osmosis (RO) system. That’s where Biobizz Calmag steps in, giving your plants the essential nutrients they need without disrupting your organic feeding regime.

No More Yellowing Leaves

Your plants might not have vocal cords, but if they could talk, they’d be screaming for calcium and magnesium. Calcium reinforces cell walls, boosting resilience against stress and disease, while magnesium is essential for photosynthesis. Without magnesium, there’s no chlorophyll. Without chlorophyll, photosynthesis grinds to a halt, leading to weak, struggling plants. Calcium and magnesium deficiencies also cause yellowing leaves and stunted growth - problems you definitely don’t want in your grow room.

Calmag. Essential for UK Growers.

If you’re using soft water, your plants aren’t getting enough minerals, and Calmag fixes that. If you rely on RO water, which strips away all minerals - including the essentials - Calmag brings them back. LED Grow Lights can increase magnesium uptake, making supplementation crucial. Heavy bloom nutrients, which are packed with phosphorus and potassium, can lock out calcium and magnesium, leading to deficiencies. If any of these apply to you, you need Calmag in your grow. 

Using Biobizz Calmag.

Using Biobizz Calmag is as easy as it gets. For RO or soft water users, add 0.5-1.5ml per litre of water from the first watering through to harvest. If correcting a visible deficiency, use it as needed at the same dosage. To boost EC levels, 1ml per litre of Calmag raises EC by 0.1 point, so adjust accordingly before adding nutrients. The best part? Biobizz Calmag integrates seamlessly with any feeding schedule without disrupting nutrient balance.

No Synthetic Additives.

There are plenty of Calmag products on the market, but Biobizz Calmag stands out for its 100% organic and certified formula. Unlike other Calmag supplements, it contains no synthetic additives and is nitrogen-free, ensuring it won’t interfere with your nutrient balance. It’s suitable for soil, coco, and hydroponic setups, preventing nutrient lockouts and deficiencies with ease. Crafted in the Netherlands, Biobizz Calmag benefits from decades of expertise in organic growing, making it a trusted choice for professionals and hobbyists alike.
