Hammerhead PK4/10 1L

£29.99 £26.99

Advanced Nutrients Hammerhead PK4/10 1L 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.
