Canna A and B are pretty easy to use. I’m not sure about the Boost and PK 13/14 products because I don’t know if they actually are doing anything. Plant seemed happy enough, but I don’t have enough experience with and without these to know if they’re worth it.

👍.

Throughout this grow, CANNA Mono Calcium and CANNA Mono Magnesium became an essential part of my feeding program. Since I grow exclusively with reverse osmosis water, having full control over my calcium and magnesium levels is incredibly important—and these products performed flawlessly. The dosing is simple and allows me to adjust the calcium-to-magnesium ratio precisely to my plants' needs. After switching to the CANNA Mono products, my plants became noticeably healthier. Deficiency symptoms disappeared, the foliage stayed strong and vibrant, and the plants were able to reach their full genetic potential. Their importance became especially clear during the flowering stage, where a balanced calcium and magnesium supply helped support healthy growth, strong flower development, and outstanding resin production right through to harvest. For anyone growing with RO water or very soft water who wants complete control over their nutrient profile, I can highly recommend CANNA Mono Calcium and CANNA Mono Magnesium. They provide consistency, flexibility, and exactly what the plants need. A big thank you to the CANNA team for creating two products that have become permanent essentials in my grows. ⭐⭐⭐⭐⭐ 5/5 – Highly recommended! 💚🌱

perfect for my tap water, easy to use thanks to the built-in measuring cup.

always positive

Love it

He's definitely doing his job well.

Canna Mono Calcium and Mono Magnesium components have absolutely convinced me in this grow. Using reverse osmosis water made precise calcium and magnesium supply particularly important—and this is where both products showed their strengths. The dosing is simple, the quality is excellent, and the plants accepted the nutrients immediately. Just a short time after adjusting the CalMag supply, the new leaves developed healthily, robustly, and vigorously. The flower development also remained stable until harvest. What I particularly like is that I can precisely adjust the calcium and magnesium ratio to my water with the mono components. This flexibility is a significant advantage for me compared to many conventional CalMag products. For anyone working with RO water or looking to tailor their nutrient supply, the Canna Mono products are an absolute recommendation. A big thank you to Canna for these high-quality products—they have become a staple in my feeding schedule! 💚🌱

Serves its purpose and the tank is not tilted.

Canna, you can't go wrong! 1+ with a star.

Basically very positive

Still my way to go on hydro.
