Product description
Advanced Nutrients HammerHead 1 L – PK bloom booster for regular flowering runs
If HammerHead is a fixed part of every flower cycle, or you're feeding a bigger room, the litre bottle gives you the lowest price per litre of the three sizes.
What's inside
HammerHead is a liquid PK booster with an NPK of 0-4-12, a P:K ratio of 1:3 and no nitrogen. The potassium comes from potassium citrate, and pH Perfect technology means no extra pH adjusting when you run it with Advanced Nutrients base nutrients. It's made for flower weeks 3 to 7 in hydro, coco and soil.
Yield of 1 L
At 2 ml per litre one bottle makes about 500 L of nutrient solution. For a 100 L tank you need 200 ml per fill, which gives you five full tanks.
Working with a tank
With larger reservoirs, add HammerHead after your base nutrients and stir the whole tank before you measure. Check EC and pH, and top up with complete mix rather than plain water so the PK level doesn't drift. Start in week 3, stop after week 7, and keep the bottle closed and out of the light between uses.
