Atami B'cuzz Blossom Builder Liquid 1L is a highly concentrated PK 18-23 bloom finisher developed for the later stages of flowering and ripening, supporting increased yield, larger fruits and flowers, improved structure and enhanced aromatic properties.

As flowering progresses, the nutritional priorities of a crop change. Plants increasingly concentrate their development on flowers, fruits and ripening, while the requirement for phosphorus and potassium becomes increasingly important.

B'cuzz Blossom Builder Liquid has been developed specifically for this later generative stage. Its concentrated PK 18-23 W/W formulation supplies high levels of phosphorus and potassium to support productive flower and fruit development as the crop approaches maturity.

Atami highlights increased yield, increased fruit size, a unique PK ratio and higher levels of sugars and essential oils among the key characteristics of Blossom Builder Liquid.

Suitable for soil, coco and hydroponic cultivation, Blossom Builder Liquid is highly concentrated and is applied at just 0.25-0.5ml/L. A 1L bottle can therefore prepare approximately 2,000-4,000 litres of nutrient solution.

Designed for later flowering & ripening

Blossom Builder Liquid is a specialist generative-stage product rather than a vegetative fertiliser. Its role becomes increasingly relevant as the crop progresses through flowering and moves towards ripening.

During this period, plants increasingly direct resources towards flower and fruit development. Phosphorus and potassium play important roles in this stage of crop development, which is reflected in Blossom Builder Liquid's concentrated PK 18-23 formulation.

Atami positions Blossom Builder Liquid as a finishing product that can be incorporated as the crop moves towards its final productive stages.

This allows growers to adapt the nutritional profile of the feeding programme as plant requirements change rather than simply increasing the concentration of the base nutrient.

Concentrated PK 18-23 nutrition

Atami specifies Blossom Builder Liquid as PK 18-23 W/W, providing a particularly concentrated source of phosphorus and potassium.

The formulation is designed around the increasing importance of these macronutrients as crops progress through flowering and fruit development.

Atami specifically highlights improved fruit structure, increased fruit size and increased yield among the intended benefits of the product.

Because Blossom Builder Liquid is highly concentrated, it should be accurately measured and incorporated into a balanced feeding programme rather than simply added on top of an already high-EC nutrient solution.

Supporting yield, fruit size, sugars & essential oils

Blossom Builder Liquid is designed around both crop productivity and final quality.

Atami highlights increased yield and increased fruit size, alongside improved aromatic properties as flowers and fruits mature.

The manufacturer also highlights a higher content of sugars and essential oils, making the product particularly relevant to flowering and fruiting crops where flavour, fragrance and final quality are important.

Final results will naturally depend on plant genetics, crop health, root development, irrigation, environment, light levels and the wider nutritional programme.

Suitable for soil, coco & hydro

B'cuzz Blossom Builder Liquid can be used across the three principal cultivation methods within the Atami nutrient range.

It is suitable for soil, coco and hydroponic cultivation, allowing growers to incorporate the same specialist bloom finisher while selecting the appropriate base nutrient for their growing medium.

This makes Blossom Builder Liquid useful across manually irrigated container crops, coco fertigation systems and appropriately managed hydroponic installations.

The base nutrient should always be selected and managed according to the growing medium and requirements of the crop.

How to use Atami B'cuzz Blossom Builder Liquid

Atami recommends using 0.25-0.5ml of Blossom Builder Liquid per litre of water.

At this concentration, use 2.5-5ml for 10L, 12.5-25ml for 50L, 25-50ml for 100L, 125-250ml for 500L and 250-500ml for 1,000L of nutrient solution.

A 1L bottle therefore prepares approximately 4,000L at 0.25ml/L or 2,000L at 0.5ml/L.

Blossom Builder Liquid is intended for later flowering and ripening. Exact timing and feeding strength should be adapted to the individual crop, its condition and the complete nutrient programme rather than following a rigid week-based schedule.

Because this is a concentrated PK product, monitor the EC of the complete nutrient solution and take account of other phosphorus and potassium products already being used.

Using Blossom Builder Liquid with a base nutrient

Blossom Builder Liquid can be integrated alongside the appropriate base nutrition for the chosen growing medium.

For coco-grown crops this may be B'cuzz Coco A&B, while soil and hydroponic growers can use the corresponding Atami base nutrient for their cultivation method.

The base nutrient provides the broader mineral nutrition required by the crop, while Blossom Builder Liquid supplies concentrated phosphorus and potassium as the plant progresses through later flowering and ripening.

This allows the feeding programme to respond to changing crop requirements without replacing the complete nutritional foundation.

Blossom Builder Liquid & B'cuzz Bloom Stimulator

Atami recommends using Blossom Builder Liquid in combination with B'cuzz Bloom Stimulator.

The two products have complementary roles. B'cuzz Bloom Stimulator provides flowering-stage stimulation, while Blossom Builder Liquid supplies concentrated PK nutrition during the later generative stages.

This allows flowering stimulation and late-stage phosphorus and potassium nutrition to be managed separately within the wider crop programme.

Blossom Builder Liquid vs Blossom Builder Tabzz

Blossom Builder Liquid and Blossom Builder Tabzz are both designed for later flowering, but they are different products with different formulations and application methods.

Blossom Builder Liquid is a concentrated PK 18-23 liquid finisher dosed into the nutrient solution at 0.25-0.5ml/L.

Blossom Builder Tabzz uses effervescent tablets that dissolve into the nutrient solution and has its own separate PK analysis and dosage instructions.

The two formats should therefore be used according to their individual application instructions rather than treated as directly interchangeable products.

Blossom Builder Liquid vs Bloombastic

Both products are used during flowering, but their formulations and roles differ.

Blossom Builder Liquid is a concentrated PK 18-23 finisher focused on phosphorus and potassium nutrition during later flowering and ripening.

Bloombastic is a PK 14-15 all-in-one bloom additive that Atami positions as a bloom stimulator, hardener, taste enhancer and activator of enzymatic processes during the final flowering stages.

Because both contribute substantial phosphorus and potassium, concentrated PK products should not automatically be stacked together. The complete nutrient programme and final EC should be considered first.

1L Blossom Builder Liquid for larger flowering programmes

The 1L bottle provides a practical size for larger reservoirs, repeat crop production and growers regularly using a late-flowering PK programme.

At the recommended 0.25-0.5ml/L dosage, each bottle prepares approximately 2,000-4,000 litres of nutrient solution.

A full outer case contains 12 x 1L bottles, providing 12 litres of Blossom Builder Liquid concentrate in total.
