Advanced Nutrients Hammerhead PK 4/10

Advanced Nutrients Hammerhead PK 4/10

Advanced Nutrients Hammerhead PK 4/10 is the modern alternative to the standard PK type flowering boosters available today. PK-type boosters were originally designed a long time ago for agricultural outdoor use where phosphorous is quickly washed out of the soil. With indoor growing this does not happen and so the ideal ratio of P to K is different. Advanced Nutrients have formulated Hammerhead to have the ideal ratio of P to K for indoor gardening. Hammerhead provides exactly the right amounts of supplemental P and K for optimal bloom boosting without over-fertilising or burning your plants.

Advanced Nutrients Hammerhead PK 10 also contains various other ingredients that your plants require a lot of during peak-blooming such as magnesium that other PK boosters do not contain. Try Hammerhead instead of your usual PK booster and then see, smell and weigh the difference in your crops.
