HammerHead is a one-part floral booster with better source components and formula integrity than PK 13-14. 


Have you ever tried a PK bloom booster only to find that it did nothing for your plants or created brown spots or leaf tip burning? Then it's time to try this one.


Specifically, we don't need a PK formula with such high amounts of phosphorus. Recent research regarding growing using Rockwool aeroponics and other hydroponic gardening systems has shown that too much phosphorus creates MANY problems for the type of plants we grow. An excess of phosphorus accumulates in your crop's root zone, where it can burn roots, interfere with the absorption of other nutrients and severely harm your yield potential. This is known as "phosphorus toxicity," You can easily check for this by looking for brown spots or leaf tip burning on your crops.

Along with increasing the size, weight, and density of your flowers, HammerHead's precise combination, type and ratio of potassium, phosphorus and magnesium has been proven to increase essential oils, aroma, and potency in hydroponic crops.

You'll see your plants bloom bigger and bigger! For best results, many growers have used HammerHead as part of a rotating cycle of timed bloom boosters during the significant bloom phase.

Advanced Nutrients provides users with products that work, cost less, and last longer, creating fantastic results.
