Green House Feeding Booster PK+, flowering additive

Green House Feeding Booster PK+ is a powdered mineral flowering supplement with NPK 0:30:27, magnesium and trace elements. It supplements the main nutrient solution with phosphorus and potassium.

Booster or base fertilizer?

Booster PK+ is used alongside a chosen base formula, such as Short Flowering, Hybrids or Long Flowering. Using it on its own does not constitute a complete feeding program.

How do you determine the dosage?

Follow the schedule for the specific substrate and growth stage. Adjust the base fertilizer dosage to account for the added booster. Dissolve the measured amount in water and check the total EC, rather than adding the booster to a solution that is already at maximum concentration.

Combining with other products

Avoid doubling up with other PK boosters unless your feeding program has been specifically adjusted to account for them. For guidance, see the Green House Feeding mineral fertilizers and supplements.
