Terralba is a French company epscialized in the manufacture of natural soil improvers for organic farming. These type of nutrients are ideal for marijuana plants - either for indoor or outdoor crops - since they provide improved organoleptic features when compared to mineral fertilizers, and are eco-friendly.

Terralba's range of products is innovative, as shown by products like Mealworm Guano, fish flour or the azomite powder. They also offer complete and balanced kits to mix with the soil so no liquid fertilizers are needed throughout the life of the plants.

One of the main goals of Terralba is developing a range of organic nutrients so that cannabis cultivation easier for everyone, with abundant and healthy harvests of the best possible quality.

The raw materials used by Terralba are not processed, except certain substances like castings which are the result of worms' digestion. All the rocks used have been crushed into powder.
