Advanced Nutrients Hammerhead 9-18
August 11, 2008
Advanced Nutrients scientists specifically designed HammerHead – a one-part floral booster to outproduce PK 13-14 and similar products. HammerHead has better source components and formula integrity than PK 13-14. Our 9-18 ratio gives specialty plants the exact amount of potassium and phosphorus that they need, and costs far less than PK 13-14.
