Hammerhead

When you need the largest harvest of the juiciest, most valuable flowers, turn to our legendary Hammerhead. Lots of companies make a potassium/phosphorus combo for use during bloom phase, but only Advanced Nutrients gives you the ideal ratio and types of these ingredients so you get higher quality, bigger flowers.

Advanced Nutrient's scientists did years of research in gardens just like yours to give you the strongest, most flower-enhancing P-K formula you can get.  Applied at a constant low level throughout flowering cycle, no more waiting for specific weeks.

Use at 1-2 mlL^-1 after first week of flower.
