Atami B'cuzz Blossom Builder Liquid 5L is a highly concentrated PK 18-23 bloom finisher developed to support final flower and fruit development, increased yield, fruit size and aromatic properties during the productive flowering phase.

As flowering progresses, crop demand for phosphorus and potassium changes significantly. B'cuzz Blossom Builder Liquid provides a concentrated source of these important flowering nutrients in a distinctive PK 18-23 W/W formulation.

Atami developed Blossom Builder Liquid to support the structure and final development of flowers and fruits. It is positioned as a specialist bloom finisher, supporting strong, healthy and substantial flower and fruit formation as the crop moves through its productive stages.

The concentrated liquid formulation is applied at only 0.25-0.5ml per litre, making the 5L container particularly economical for professional growers, larger irrigation systems and high-volume nutrient reservoirs.

Blossom Builder Liquid can be used with soil, coco and hydroponic cultivation and is suitable for use through irrigation systems. Its liquid format also allows growers to adjust the application rate precisely according to crop requirements.

When should Blossom Builder Liquid be used?

Blossom Builder Liquid is designed for the flowering and ripening stages, when crops are directing increasing amounts of energy and nutrition towards flower and fruit development.

Current Atami grow guides introduce Blossom Builder Liquid during the productive flowering stages at 0.25-0.5ml/L. The exact timing should follow crop development rather than relying entirely on fixed calendar weeks.

Atami recommends Blossom Builder Liquid for a range of flowering and fruit-bearing crops. Manufacturer examples include chilli peppers and blueberries, as well as flowering ornamental plants such as Buddleia and Amaranth.

Because different crops have different flowering durations and nutritional requirements, growers can adjust the liquid dosage within Atami's recommended range to suit the crop and feeding programme.

How to use Atami B'cuzz Blossom Builder Liquid

Add 0.25-0.5ml of Blossom Builder Liquid per litre of nutrient solution during the appropriate flowering stages.

At 0.25ml/L, use 2.5ml for 10L, 12.5ml for 50L, 25ml for 100L, 125ml for 500L and 250ml for a 1,000L nutrient reservoir.

At 0.5ml/L, use 5ml for 10L, 25ml for 50L, 50ml for 100L, 250ml for 500L and 500ml for a 1,000L nutrient reservoir.

One 5L container can therefore prepare approximately 10,000 litres of nutrient solution at 0.5ml/L or up to 20,000 litres at 0.25ml/L.

Mix the standard nutrient solution first before adding the required quantity of Blossom Builder Liquid. Mix thoroughly to ensure even distribution throughout the reservoir.

Because Blossom Builder Liquid provides concentrated phosphorus and potassium, consider the complete nutrient programme when determining application strength. Avoid unnecessarily combining multiple high-PK products without accounting for their combined nutrient contribution.

Understanding the PK 18-23 formulation

Blossom Builder Liquid has a PK analysis of 18-23 W/W, providing a substantial concentration of both phosphorus and potassium.

Phosphorus plays important roles in plant energy transfer and reproductive development, while potassium is involved in numerous physiological processes associated with water regulation, nutrient movement and crop development.

As crops progress through flowering and fruiting, these macronutrients become particularly important to productive development. Blossom Builder Liquid provides them in a concentrated formulation designed specifically for this stage of cultivation.

The 18-23 formulation also distinguishes Blossom Builder Liquid from other Atami finishing products. It should therefore be selected and dosed according to the complete feeding strategy rather than assuming all bloom finishers perform the same nutritional role.

Suitable for soil, coco and hydroponics

One of the major advantages of Blossom Builder Liquid is its flexibility across different cultivation methods.

Atami specifies the product for use with soil, coco and hydro substrates. Its concentrated liquid formulation can be incorporated into the appropriate base nutrient programme for each growing method.

It is also suitable for use through irrigation systems, making the 5L format particularly practical for growers using larger mixing tanks, drip irrigation or automated fertigation.

The ability to measure between 0.25 and 0.5ml/L also gives professional growers more control over application strength than a fixed-dose tablet format.

Blossom Builder Liquid vs Blossom Builder Tabzz

Although both carry the Blossom Builder name, the Liquid and Tabzz versions should not be treated as interchangeable products.

Blossom Builder Liquid has a PK 18-23 W/W analysis and is dosed at 0.25-0.5ml/L. The liquid format gives growers precise control over the concentration used for different crops and reservoir sizes.

Blossom Builder Tabzz use a different PK formulation and are supplied as pre-measured effervescent tablets. They are particularly convenient where growers want a simple tablet-based finishing treatment.

Always follow the application guidance for the specific Blossom Builder product being used rather than transferring the dosage or nutrient analysis from one format to another.
