Green House Powder Feeding Booster for targeted PK nutrition during flowering
Green House Powder Feeding Booster 50g-25kg is a mineral PK booster in powder form designed for the flowering stage. With an NPK ratio of 0-30-27, it supplies primarily phosphorus and potassium while adding magnesium and selected trace elements. The water-soluble additive can be used alongside a suitable base nutrient when plants require additional mineral nutrition during flowering. It is suitable for soil, coco and hydroponic growing systems.
Balanced phosphorus, potassium and magnesium supplementation
The formulation contains 30% water-soluble phosphorus pentoxide and 27% water-soluble potassium oxide. A further 8.2% water-soluble magnesium oxide is included. The added magnesium and trace elements help provide a broader mineral profile rather than relying on phosphorus and potassium alone. Within its mineral feeding system, the manufacturer combines the booster with products such as Green House Powder Feeding Calcium. You can find other mineral products from the range in the Green House Powder Feeding range.
Water-soluble powder for nutrient solutions
The booster is dissolved in water and applied together with the chosen base nutrient. According to the manufacturer, its maximum solubility is 250 g/L of water, while 30 g/L is recommended for preparing a concentrated stock solution. A concentration of 1 g/L Booster contributes approximately 1.0 mS/cm EC according to the manufacturer. This makes the product suitable for accurately managed irrigation and hydroponic systems as well as conventional hand watering.
Dosage during flowering
Growmart specifies a progressive flowering schedule: use 2–3 g per 10 L of nutrient solution during flowering weeks three and four, 3–4 g per 10 L during weeks five and six, and 4–5 g per 10 L during weeks seven and eight. Dissolve the powder thoroughly and use it alongside the planned base feed. With mineral nutrition, check the final EC and pH of the nutrient solution and adjust the overall concentration to suit the plants, source water and growing medium.
