Atami Bi-Bloombastic 250ml is a highly concentrated PK 8-12 all-in-one bloom additive combining phosphorus, potassium, iron and organic compounds to support flowering, fruit development, flavour and yield during the final stages of the crop cycle.
Described by Atami as Bloombastic with a 'green twist', Bi-Bloombastic has been developed for growers looking for an organic-natured flowering additive. It works as a bloom stimulator, hardener, taste enhancer and activator of various enzymatic processes while supporting the biological activity associated with the flowering root zone.
Bi-Bloombastic contains a high concentration of phosphorus, potassium and iron alongside organic compounds. Atami explains that its fertilisers are more readily metabolised by micro-organisms than mineral fertilisers due to the product's organic nature.
During flowering, these fertilisers support micro-organisms around the root zone while the concentrated PK formulation supports flower and fruit development. Atami specifically highlights increased fruit size, yield and flavour among the benefits of Bi-Bloombastic.
Applied at 1-2ml/L, a 250ml bottle prepares approximately 125-250 litres of nutrient solution. This listing is supplied individually, with 12 x 250ml bottles per full outer case.

What is Atami Bi-Bloombastic suitable for?
Bi-Bloombastic is intended for flowering and fruiting plants during the later stages of their productive cycle. Atami gives examples including chilli peppers, strawberries and blueberries, together with flowering ornamental plants such as orchids and violets.
It can be used with plants grown in Hydro, Coco and Soil, although its method of application differs from many conventional mineral flowering additives.
Atami recommends Bi-Bloombastic during the final 4-6 weeks of the flowering stage as an additive to the crop's regular nutrients.
The exact duration of flowering varies between plant species, so growers should follow actual crop development rather than treating the recommended period as a rigid calendar schedule.
What makes Bi-Bloombastic different?
Standard Bloombastic and Bi-Bloombastic share the all-in-one bloom additive concept, but their formulations are different.
Bi-Bloombastic contains organic compounds and is formulated to support micro-organisms during flowering. Atami explains that the fertilisers contained within Bi-Bloombastic are better metabolised by micro-organisms than mineral fertilisers due to their organic nature.
This makes Bi-Bloombastic particularly relevant to growers using biologically active feeding programmes who want concentrated flowering support while maintaining a strong focus on microbial activity within the root environment.
Its analysis is PK 8-12 W/W, compared with the PK 14-15 formulation of standard Bloombastic, and its recommended application rate is also different.
How to use Atami Bi-Bloombastic
Apply Bi-Bloombastic during the final 4-6 weeks of flowering as an additive to the plant's regular nutrient programme.
Use at a concentration of 1-2ml per litre of water. This equals 10-20ml for 10L, 50-100ml for 50L and 100-200ml for 100L of nutrient solution.
A 250ml bottle prepares approximately 250 litres at 1ml/L or 125 litres at 2ml/L.
Bi-Bloombastic can be combined with basic nutrients and other suitable additives, but growers should pay attention to the EC value of the complete nutrient solution and adjust the overall programme according to crop requirements.
Important irrigation guidance: Bi-Bloombastic should not be automatically dosed through irrigation systems. Atami advises that when an irrigation system is being used, Bi-Bloombastic should be administered manually with a watering can because its formulation can otherwise create a risk of clogging.
Understanding Bi-Bloombastic PK 8-12
Bi-Bloombastic has a PK analysis of 8-12 W/W, giving it a potassium-dominant phosphorus-to-potassium profile.
Phosphorus contributes to important plant processes associated with energy transfer and reproductive development, while potassium is involved in water regulation, nutrient movement and many processes associated with productive flower and fruit development.
Atami also highlights the product's high concentration of iron. Iron is an essential micronutrient involved in important plant metabolic processes and contributes to normal plant development.
Bi-Bloombastic combines this mineral contribution with organic compounds and its support for micro-organisms, giving the product a distinctly different formulation from Atami's standard mineral-focused Bloombastic.
Bi-Bloombastic as part of a flowering programme
Bi-Bloombastic is an additive rather than a complete base nutrient. Continue providing an appropriate basic nutrient programme while introducing Bi-Bloombastic during the recommended flowering period.
Atami's own grow guides pair Bi-Bloombastic with its ATA NRG nutrient range, demonstrating its role as the concentrated flowering additive within a broader feeding programme.
Because the product contributes additional phosphorus, potassium, iron and other compounds to the nutrient solution, the complete feeding programme should always be considered when assessing nutrient strength.
Crop condition, growing environment, light intensity and species can all affect nutrient demand. Use the manufacturer's application rate as a guideline and adjust feeding according to actual crop response.
