Advanced Nutrients Hammerhead PK Bloom Booster – 250ml

295
£2.95
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 places considerably more emphasis on potassium than phosphorus, creating a 1:3 phosphorus-to-potassium ratio for growers who want targeted PK supplementation alongside their normal feeding programme.
Because Hammerhead contains no added nitrogen, it allows additional phosphorus and potassium to be introduced without increasing the nitrogen contribution of the crop's base feed.
Advanced Nutrients also highlights potassium citrate within the formulation. Hammerhead is designed to work alongside a complete base nutrient rather than replace it and is particularly well matched to the Sensi Terra feeding programme.
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 current European formulation.
- No added nitrogen – adds PK without unnecessarily increasing nitrogen in the feeding programme.
- 2ml/L application rate – simple dosing for tanks, reservoirs and hand-mixed feeds.
- Works alongside base nutrients – supplements the wider nutrient programme rather than replacing it.
- Broad nutrient compatibility – suitable alongside Advanced Nutrients pH Perfect and non-pH Perfect base feeds as well as compatible third-party programmes.
- Compact 250ml size – ideal for smaller reservoirs, trials and lower-volume growing systems.
What is Advanced Nutrients Hammerhead suitable for?
Hammerhead is designed for crops requiring additional phosphorus and potassium alongside a complete base nutrient programme.
Advanced Nutrients' current European schedule uses Hammerhead during established vegetative development and again from the developing flowering phase through active and later flowering. For Creation, it is more useful to follow crop stage rather than assuming every variety follows the same calendar.
Hammerhead is particularly suited to growers using the Advanced Nutrients Sensi Terra range, although it can also be incorporated into compatible pH Perfect, non-pH Perfect and third-party feeding 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 before adding the next product.
Add Hammerhead at 2ml per litre when it is required within the feeding programme. During flowering, use it from the developing bloom phase through active and later flowering, then discontinue it 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 rest of the crop's macro and micronutrient requirements.
