The Power of a 1:3 PK Ratio Unleashed!

Go beyond the standard PK booster with Hammerhead, a tried-and-true bloom booster rigorously researched and tested on the type of plant you grow. With the ideal 1:3 PK ratio your crops crave, Hammerhead fuels floral production to reward you with the lush, potent, sizable harvest you deserve.

• Zero added nitrogen protects your plants from the dangers of nitrogen toxicity
• Optimal 1:3 PK ratio required for heavier yields of dense, potent, flavorful flowers
• Potassium citrate maximizes nutrient uptake without toxicity from common chelators

As a grower of high-value crops, you deserve better than generic fertilizers designed for corn or soybeans.
Most of these traditional ag formulations feature the standard 13:14 PK ratio. And that might be great for your average crops… But NOT for your high-value plants.
Because here’s the thing — too much phosphorus can harm your roots, block nutrient absorption, and ultimately limit your yields.

After rigorous research, we discovered that a 1:3 PK ratio is the ideal amount to fuel unprecedented floral production…
Without causing the phosphorus toxicity that comes from generic fertilizers.
And that’s exactly what you’ll find in the new and improved HammerHead — a bloom booster guaranteed to grant you the harvest you deserve.
By providing your plants with the precise phosphorus-to-potassium ratio they crave, HammerHead unlocks the potential for a larger, denser, and more flavorful crop.
And we didn’t just include any potassium in Hammerhead.

Maximize Nutrient Uptake For Heavy, Potent, Flavorful Flowers
You see, to get the most from your crops, you MUST provide phosphorus in the most efficient way possible.
Which is why, instead of sulfate of potash, you’ll find potassium citrate in your HammerHead bloom booster.
Citrate is a high-quality chelating agent that ensures your crops get the phosphorus they need, not sulfate — withOUT the toxicity associated with common chelators.

Advanced Nutrients base nutrients already contain the ideal amount of nitrogen, we’ve excluded it entirely from the HammerHead formulation.
