Soil A+B Growth Hard Water is a two-component fertilizer specially formulated for soil crops that use tap water or hard water. Ideal for the vegetative phase of cannabis cultivation, it promotes vigorous and healthy growth.

Tierra A+B Growth Hard Water from Dutchpro is a two-part base nutritional system (A+B) that provides plants with all the essential macro and micronutrients needed during the growth phase.
It is specifically designed for soil crops with hard water, taking into account the presence of lime, chlorine, and other minerals that can interfere with nutrient absorption. Its formulation is based on Liebig's Law of the Minimum, ensuring a balanced supply of the 17 essential nutrients, allowing plants to develop strong structures and greater resistance to diseases in their most vulnerable stages.
The hard water version of this fertilizer contains agents that help neutralize the negative effects of calcium and chlorine, maintaining a stable and effective nutrient solution. During the vegetative phase, cannabis needs a constant supply of nitrogen, phosphorus, and potassium, as well as trace elements that promote cell division, root development, and tissue formation.
Tierra A+B Growth Hard Water covers all these needs, with an NPK of 3-2-5 that guarantees balanced growth. Dutchpro's A+B systems are known for not crystallizing and being suitable for any irrigation system.
In addition, its food-grade formulation ensures rapid absorption, with no residues accumulated in the substrate, resulting in cleaner and stronger plants ready for lush flowering.
The recommended dosage of Tierra A+B Growth Hard Water varies according to the week of the vegetative cycle.
For one liter of water, apply between 2.5 ml and 5.0 ml of each component (A and B), adjusting the EC level between 1.5 and 2.0. It is important to shake well before use, and always add component A first, mix, and then add B. Use only during the growth phase.
Store the product in a cool, closed place in its original container. Keep out of reach of children.
Tierra A+B Growth Hard Water features a formula with an NPK ratio of 3-2-5, providing an ideal balance for the formation of healthy vegetative structures.
It also includes essential micronutrients such as iron, manganese, boron, zinc, and molybdenum.
All components are food grade, ensuring maximum assimilation without residue accumulation in the substrate, which is essential in cannabis cultivation.
