Mills Nutrients runs one base feed and four supplements. That is the whole range, and it is deliberate. Basis A&B works across soil, coco and hydro, and is heavily chelated so it stays available across a wider pH band than most mineral feeds - which is what lets a single base cover every medium.
- Basis A&B: The universal two-part base feed - soil, coco or hydro, same bottles. See all base nutrients.
- Start-R: Root stimulant for the first weeks - browse root stimulators.
- C4: The flowering booster, used through bloom for bulk and quality - see flowering boosters.
- Mills PK: Late-flower phosphorus and potassium - more PK boosters.
- Vitalize: A bioavailable silicon supplement for stronger cell walls and stress tolerance - see silicon additives.
- Cal Mag: Mills Cal-Mag for coco and RO water - browse all Cal-Mag.
- Starter kit: The Mills Nutrients Starter Kit brings the core range together - see nutrient starter kits.
Why choose Mills?
One base feed for every medium is genuinely convenient, and the heavy chelation means the nutrients stay available even when your pH drifts - which it will. It is a premium product, but the dose rates are low and there are only six bottles in the whole range to buy.
Mills FAQs
Can I really use Basis A&B in soil and hydro?
Yes. The chelation is what makes it work across media. You adjust dose rate and frequency rather than switching product.
Is Mills expensive?
The bottles are premium-priced, but recommended dose rates are modest and the range is short - most growers run five products total.
Why buy Mills from The Hydro Bros?
We stock the Mills range in full, ship discreetly across the UK and Europe, and know these products because we use them. With excellent customer reviews on Trustpilot and staff who actually grow, you get the right kit first time.
