Green House Feeding Mineral Line Booster PK+, 2.5 Kg

Complete you garden with all the important micro nutrients and supplements your plants love

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. GHF 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.

Balanced nutrients

Balanced plant nutrition is essential to achieve high yields. If one of the essential plant nutrients is deficient, plant growth is limited to the amount of the lowest available nutrient, even when all other essential nutrients are abundant.

Furthermore, even if the least used nutrient is not present, the plant will not be able to take in all the other available nutrients, indicating that the elements used intrace amounts are as essential as the macro-nutrients.

The 'Liebig barrel' is used to demonstrate this principle.

The availability of the most abundant nutrient in the soil is only as good as the availability of the least abundant nutrient in the soil.

Green Hosue Feeding Booster contains not only Phosphorus (P) and Potassium (K) but also extra Magnesium (Mg) and trace elements to ensure the nutrient content is balanced and there is no lack of any element that might limit the uptake of others.
