Booster PK+ is an additive that is specially 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 a very professional, plant-specific line of nutrients for healthy and productive plants.



Booster PK+ has added extra magnesium and trace elements to avoid the limited 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.

How To Use

Booster can be used in combination with powder feeding or any other base nutrients.

The values below work perfectly with the vast majority of fertilizers:

  • When growing in soil, feed every other watering.
  • During week 3 & 4 mix 2 - 3g of Booster PK+ per 10L of water
  • During week 5 & 6 mix 3 - 4g of Booster PK+ per 10L of water
  • During week 7 & 8 mix 4 - 5g of Booster PK=per 10L of water
  • Water + base nutrients should not have a higher EC than 1.3mS/cm.

These values are based on a 10 week flowering time. Values should be adjusted to meet requirements of your flowering time.
