WHY IS GREEN HOUSE FEEDING BOOSTER PK+ GOOD FOR MY PLANT?
GHF Booster PK+ is the perfect ratio of Phosphorus (P) and Potassium (K) for maximizing weight without causing an imbalanced nutrient profile.
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 in trace 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.
COMPLETELY WATER SOLUBLE!
Stop paying for product you can’t use. Booster PK+ is 100% water soluble.
Maximum Solubility:Â 2.0lb/gal or 250g/L Water
Recommended for Stock Solution:Â 4oz/gal or 30g/L Water
9% SULFUR
GHF Booster PK+ contains 9% sulfur. The addition of sulfur aids in EXTREME TERPENE AND OIL PRODUCTION as well as flower density.

GREEN HOUSE FEEDING – SIMPLE FEED SCHEDULE
The feed schedule below can be used without monitoring pH and EC values; however, we do recommend to always measure pH and EC for best results. Tap water hardness should also be taken into consideration.
When using hard water and nutrient rich soil, one product (Short Flowering, Hybrids or Long Flowering) can be used from start to finish, making the GHF feeding line very cost efficient.
It is possible to use a combination of GHF base nutrients and Booster PK+
If a range of values is mentioned below (e.g. 5-7g/10L), it means that the first value is used to start with and should be increased every week until the final value is reached.
