Cannabis Nutrients and Professional Fertilizer Range
FertiQi produces cannabis nutrients for professional cultivation – from base nutrition to specialty actives, pH management and living soil. Everything is formulated, produced and filled in-house in Vilassar de Mar near Barcelona and shipped from our warehouse in Germany. You can run your current program with our products, or we help you design a better one.
FertiQi supplies licensed cultivators, cannabis social clubs, brands, distributors and resellers. We do not sell to end consumers.

Cannabis nutrients built around your grow
The right mineral is the one that is available at the right moment. Our team has grown cannabis and managed licensed operations, and we design feed programs around your data: substrate and system, water analysis, light schedule, genetics, current products and cycle length. Read our guide on building a consistent cannabis feeding program, or learn how we develop custom fertiliser solutions.
Who we supply
