£119.95

A concentrated 0-1-3 liquid bloom booster designed to support strong, full flower development through the main mid-flowering phase.

Advanced Nutrients Big Bud is a specialist liquid flowering supplement developed for the main flower-building stage of the crop cycle. Its 0-1-3 nutrient profile provides phosphorus and potassium in a carefully balanced ratio, helping growers supplement their base nutrition as flowering demand increases.

Rather than relying on an excessively high phosphorus concentration, Big Bud uses a 3:1 potassium-to-phosphorus ratio. This balance provides targeted PK nutrition for actively flowering crops while fitting neatly alongside a complete flowering base nutrient.

Big Bud sits between early-flowering and late-flowering supplements in the Advanced Nutrients programme. Once initial flower formation is established, it supports the crop through its main flower-building period before giving way to the late-flowering stage. The 10L format is particularly well suited to commercial growers, larger reservoirs and repeated flowering cycles.

Why choose Advanced Nutrients Big Bud?

  • Specialist mid-bloom booster – developed for the main flower-building phase of flowering.
  • Balanced 0-1-3 formula – supplies phosphorus and potassium without adding nitrogen.
  • 3:1 potassium-to-phosphorus ratio – provides a potassium-led PK profile for active flowering.
  • Targeted flowering nutrition – complements the crop's normal base nutrient as flowering demand increases.
  • Supports flower development – formulated to create favourable nutritional conditions during the main period of floral growth.
  • Fits a staged flowering programme – follows early flower initiation products and precedes late-flowering supplements such as Overdrive.
  • Simple 2ml/L application rate – straightforward to calculate across small and commercial reservoirs.
  • Suitable for hydroponics & coco – compatible with diverse hydroponic growing media and coco coir.
  • Commercial 10L format – provides enough concentrate for approximately 5,000L of nutrient solution at 2ml/L.

What is Advanced Nutrients Big Bud suitable for?

Big Bud is designed for flowering and fruiting crops during the main period of active flower development. It is a bloom supplement rather than a complete base nutrient, so it should be used alongside an appropriate flowering feed.

In crop-stage terms, introduce Big Bud once the initial transition into flowering and early flower-setting stage is established. Continue through active mid flowering, then discontinue it as the crop progresses into its late-flowering and finishing phase.

Big Bud can be incorporated into indoor and outdoor growing programmes and used with hydroponics, coco coir, regular watering and irrigation systems. It is also suited to continuous liquid-feed systems including aeroponics, drip irrigation and emitters, nutrient film technique (NFT), flood and drain and deep water culture (DWC).

How to use Advanced Nutrients Big Bud

Add Big Bud at 2ml per litre of nutrient solution during the active mid-flowering phase. Use it alongside the crop's normal flowering base nutrient rather than as a standalone feed.

For 10L of nutrient solution, use 20ml. For 50L, use 100ml. For 100L, use 200ml. For a 500L reservoir, use 1L. For a 1,000L reservoir, use 2L.

A full 10L container provides enough Big Bud for approximately 5,000 litres of nutrient solution at the 2ml/L application rate.

As the crop moves beyond its main flower-building stage and into late flowering, discontinue Big Bud and move to the appropriate late-flowering part of the feeding programme.

Standard Big Bud and Big Bud Coco are separate formulations. Standard liquid Big Bud is a general bloom booster, while Big Bud Coco is specifically formulated around the nutritional characteristics of coco coir.

What is the difference between Big Bud Liquid and Big Bud Powder?

They are different formulations and should not be treated as interchangeable concentrates. Big Bud Liquid is measured in millilitres, while Big Bud Powder is a water-soluble product measured by weight. Follow the application rate for the specific version being used.
