Complete Nutrient Kit 8 x 1L – Coco A&B, CalMag, Root & Bloom Boosters – British Minerals
Eight bottles. One box. No more standing in the feed aisle doing maths.
Here's a quiet truth about plant feeding: most people don't fail because they bought the wrong nutrient. They fail because they bought half the programme, then improvised the rest. The British Minerals Premium Nutrient Kit removes the improvisation. It's the entire UK-made range – eight full 1 litre bottles – in a single box, with a feed schedule that tells you what to pour and when, from first roots to final harvest.
Bought separately, these eight bottles cost us over £160 to put on the shelf as singles. In the box, you pay a great deal less. That's not a promotion – it's simply what happens when a manufacturer packs the whole range once instead of eight times.
What's in the box (8 x 1L)
- Pure Coco A & B (2 x 1L) – the two-part base feed. Complete macro and micro nutrition formulated for coco coir, covering both growth and flowering stages.
- CalMag (1L) – concentrated calcium and magnesium. Corrects soft or RO water and heads off the yellowing and leaf-edge burn that coco is famous for.
- Root Mass (1L) – root stimulator with minerals, natural plant extracts, vitamins and microalgae. A denser root zone early pays dividends for the entire crop.
- GrowZym (1L) – beneficial enzymes that break down old root material and keep the root zone clean, so nutrients go to living roots rather than dead ones.
- Fruit Boost (1L) – plant extracts, sugars, amino acids and vitamins to accelerate metabolism for heavier, more uniform fruit with better flavour.
- Pro PK 13/14 (1L) – the classic phosphorus/potassium flowering booster, added mid-bloom to drive flower and fruit set.
- Money Shot (1L) – the late-flowering finisher: phosphorus, potassium, organic acids and amino acids for extra flower mass, aroma and visual appeal.
- Nutrient schedule – so you're never guessing doses.
Who it's for
Anyone growing fruiting and flowering plants in coco, hydro or soilless mixes – tomatoes, chillies, peppers, strawberries, cucumbers, aubergines and flowering ornamentals – who wants a joined-up programme rather than a cupboard full of mismatched bottles. CalMag, Root Mass, GrowZym and the boosters all work across soil, coco and hydro; the Pure Coco A&B base is optimised for coco.
Why this beats building your own
- Everything matched: one manufacturer, one schedule, designed to work together – no clashing chemistries.
- 100% UK manufactured by a brand with over 20 years in hydroponics and garden centres.
- Full 1L bottles, not sample-size tasters – enough to run a proper grow, not just trial one.
- Serious saving versus buying the eight bottles individually.
Rose's Pro-Tip: Always add CalMag to your water first, then Pure Coco A, stir, then B – never pour A and B into each other neat. Check your pH last, once everything is in. Most "mystery deficiencies" in coco are really just mixing-order mistakes.
Safety
Some products in this kit carry hazard warnings (including Pure Coco A&B and Pro PK 13/14) – they can cause skin and serious eye irritation. Wear gloves and eye protection when handling concentrates, wash hands after use, keep out of reach of children, and read each bottle's label before use.
