Unit price perEstimated delivery between September 19 and September 21.
A concentrated 3-13-26 water-soluble flowering nutrient designed to work with Cultivator Series Base throughout the bloom phase.
Advanced Nutrients Cultivator Series Bloom is the flowering component of the three-part Cultivator Series water-soluble base nutrient system. It is paired with Cultivator Series Base as crops move from transition and early flowering through active flower development and later bloom.
Its 3-13-26 analysis provides the phosphorus and potassium-led nutrition required by the wider Cultivator Series programme during flowering. The formula also supplies magnesium, sulphur and a range of micronutrients, giving commercial growers a carefully structured dry nutrient system rather than relying on a single fixed nutrient ratio throughout the crop cycle.
Supplied as a concentrated water-soluble powder, the 1kg bag is easy to weigh and mix accurately while avoiding the bulk associated with equivalent volumes of liquid concentrate. It is suitable for hydroponics, coco and a wide range of continuous liquid-feed systems.
Why choose Advanced Nutrients Cultivator Series Bloom?
- 3-13-26 flowering formulation – phosphorus and potassium-led nutrition designed for the bloom phase.
- Part of a complete three-part system – works with Cultivator Series Base rather than functioning as a standalone feed.
- Crop-stage feeding – application changes through early, active and later flowering to match changing nutritional demand.
- Water-soluble powder – concentrated dry nutrition for accurate weighing and efficient storage.
- Contains magnesium & sulphur – alongside the primary NPK analysis and micronutrient package.
- Suitable for hydroponics – developed for diverse hydroponic growing media and liquid-feed systems.
- Coco coir safe – suitable for coco-based growing programmes.
- Professional three-part approach – allows the nutrient balance to change as crops progress through flowering.
What is Cultivator Series Bloom suitable for?
Cultivator Series Bloom is designed for flowering and fruiting crops using the Advanced Nutrients Cultivator Series programme. It replaces the Grow component as the crop moves out of vegetative development and is then used alongside Cultivator Series Base.
The amount of Bloom changes with crop stage. The manufacturer programme begins at a moderate rate during transition and early flowering, increases the Bloom concentration during the main active flowering period, then reduces it again as the crop moves into later flowering and finishing.
Advanced Nutrients identifies Cultivator Series as suitable for indoor and outdoor growing, regular watering, hydroponics and coco coir. Compatible continuous liquid-feed systems include aeroponics, drip irrigation and emitters, nutrient film technique (NFT), flood and drain and deep water culture (DWC).
How to use Cultivator Series Bloom
Cultivator Series Bloom is used together with Cultivator Series Base during flowering. The two components are adjusted as the crop develops rather than being applied at one fixed rate throughout the entire bloom phase.
During transition and early flowering, use Bloom at 4g per US gallon, approximately 1.06g/L, alongside Base at the corresponding Cultivator Series rate.
During active flowering and peak flower development, increase Bloom to 6g per US gallon, approximately 1.59g/L. The Cultivator Series programme reduces the amount of Base during this stage as the balance shifts towards Bloom.
During later flowering and finishing, reduce Bloom back to 4g per US gallon, approximately 1.06g/L, while continuing to follow the corresponding reduced Base rate.
Accurately weigh the required powder and dissolve it thoroughly into water. Never mix Cultivator Series components together in concentrated form. Each component should be introduced to water and dissolved properly as part of the complete nutrient preparation process.

Advanced Nutrients Cultivator Series Bloom FAQs
What is the NPK of Cultivator Series Bloom?
Cultivator Series Bloom has an NPK analysis of 3-13-26, providing a phosphorus and potassium-led nutrient profile for the flowering phase.
Is Cultivator Series Bloom a standalone fertiliser?
No. Bloom is one component of the Cultivator Series three-part base nutrient system and should be used with Cultivator Series Base during flowering.
How much Cultivator Series Bloom should I use?
The Bloom rate changes with crop stage. Advanced Nutrients uses 4g per US gallon during early flowering, increases this to 6g per US gallon through the main active flowering period, then reduces Bloom back to 4g per US gallon during later flowering.
How much Cultivator Series Bloom is 4g per US gallon in litres?
A rate of 4g per US gallon converts to approximately 1.06g of Cultivator Series Bloom per litre of nutrient solution.
How much is 6g per US gallon in litres?
A rate of 6g per US gallon converts to approximately 1.59g/L. This is the higher Bloom rate used during the main active flowering period in the Cultivator Series programme.
How much Cultivator Series Bloom do I need for 100 litres?
At the 4g per US gallon rate, use approximately 105.7g for 100 litres. At the higher 6g per US gallon active-flowering rate, use approximately 158.5g for 100 litres.
Do I use Cultivator Series Base with Bloom?
Yes. Cultivator Series Base is used alongside Bloom during the flowering programme. Its application rate is progressively reduced as the flowering cycle develops, so the two products should be dosed according to the Cultivator Series programme rather than at equal rates throughout flowering.
When do I switch from Cultivator Series Grow to Bloom?
Make the change as the crop moves out of vegetative development and into transition and flowering. At this point the Cultivator Series programme changes from Grow plus Base to Bloom plus Base.
Can Cultivator Series Bloom be used in hydroponics?
Yes. Cultivator Series is suitable for hydroponic growing and continuous liquid-feed systems including aeroponics, drip irrigation, NFT, flood and drain and deep water culture.
Can Cultivator Series Bloom be used in coco?
Yes. Advanced Nutrients specifically identifies Cultivator Series as safe for use with coco coir.
What sizes of Cultivator Series Bloom are available in Europe?
Advanced Nutrients lists Cultivator Series in 1kg and 10kg bags for the European market.
