Advanced Nutrients Hammerhead PK Bloom Booster – 1L

995
£9.95
Unit price perEstimated delivery between September 19 and September 21.
A concentrated 0-4-12 PK bloom booster with a potassium-led 1:3 phosphorus-to-potassium ratio and no added nitrogen.
Advanced Nutrients Hammerhead is a specialist PK supplement developed for the European market. Its 0-4-12 analysis provides a deliberately potassium-led nutrient profile, supplying phosphorus and potassium alongside the crop's normal base nutrient during key stages of development.
With no added nitrogen, Hammerhead allows growers to increase phosphorus and potassium without unnecessarily adding more nitrogen to the feeding programme. Advanced Nutrients uses potassium citrate within the formulation and has designed Hammerhead to complement its Sensi Terra nutrient range particularly well.
The concentrated 2ml/L application rate makes the 1L bottle easy to work into both hand-mixed feeds and larger nutrient reservoirs, with enough concentrate to prepare approximately 500 litres of solution at the standard rate.
Why choose Advanced Nutrients Hammerhead?
- 0-4-12 NPK – concentrated phosphorus and potassium supplementation with no added nitrogen.
- 1:3 phosphorus-to-potassium ratio – a deliberately potassium-led PK profile.
- Potassium citrate – the potassium form highlighted by Advanced Nutrients in the European Hammerhead formulation.
- No added nitrogen – provides additional PK without increasing the nitrogen contribution of the feeding programme.
- Concentrated 2ml/L rate – straightforward dosing for hand watering and nutrient reservoirs.
- Works alongside base nutrients – supplements a complete feeding programme rather than replacing the base feed.
- Designed to complement Sensi Terra – particularly well suited to the Advanced Nutrients Sensi Terra programme.
- Broad nutrient compatibility – can also be incorporated into compatible Advanced Nutrients and third-party feeding programmes.
What is Advanced Nutrients Hammerhead suitable for?
Hammerhead is designed for growers who want targeted phosphorus and potassium supplementation alongside a complete base nutrient.
The official Advanced Nutrients programme uses Hammerhead during established vegetative development and then again from developing flowering through active and later flowering. Following crop stage rather than fixed calendar weeks makes the guidance useful across varieties with different production cycles.
Hammerhead is particularly suited to the Advanced Nutrients Sensi Terra range, but it can also be incorporated into compatible pH Perfect, non-pH Perfect and third-party nutrient programmes.
How to use Advanced Nutrients Hammerhead
Shake the bottle thoroughly before use. Prepare the normal base nutrient solution first, mixing each nutrient or supplement thoroughly into the water as it is added.
Add Hammerhead at 2ml per litre when required within the feeding programme. During flowering, the official programme introduces Hammerhead once flowering is developing and continues it through active and later flowering before stopping for the final flush.
For 10L of nutrient solution, use 20ml. For 50L, use 100ml. For a 100L reservoir, use 200ml.
Hammerhead is a PK supplement rather than a complete fertiliser, so continue using the appropriate base nutrient to provide the wider macro and micronutrient profile required by the crop.
