This additive is especially formulated to provide adequate amounts of Phosphorus, Potassium, Magnesium and micronutrients to increase the resin production and the formation and density of flowers.

The combination of Green House Powder Feeding, Calcium and Booster creates very professional, plant-specific line of nutrients for healthy and productive plants.

We added extra magnesium and trace elements to our PK Booster to avoid that they limit the uptake of phosphorus and potassium if the ratios are not balanced.

Plants can only perform to their full genetic potential if all elements are sufficiently available.
