Where this formulation fits
Use Blue for balanced mid-season feeding for nursery, pot and bedding crops. Crop response depends on the species, growth stage, root-zone conditions and the balance of nutrients already supplied by the growing medium and irrigation water.
Where hard or soft irrigation water presents particular challenges, compare the dedicated Universol Hard Water and Soft Water ranges before selecting a feed.
Preparing & applying the feed
Dissolve the fertiliser in water using the current ICL mixing and application guidance for the product and your crop. Check irrigation-water analysis, including alkalinity and EC, when setting a fertigation programme.
Monitor stock solution clarity, feed EC and pH, crop growth and drainage. Avoid assuming a single concentration is appropriate for all crops or irrigation systems. Check concentrated stock-tank compatibility before mixing with other fertilisers, especially calcium-containing products.
Managing a professional nutrition programme
Consider how this water-soluble feed complements any controlled-release fertiliser already present in the substrate. Review nutrition as crops establish, grow and finish, rather than relying on a fixed recipe for the entire production period.
Store sealed in a dry area, protect from moisture and follow the current product label and safety information when handling fertilisers.

A highly concentrated water-soluble Grow component for the Advanced Nutrients Cultivator Series three-part base nutrient system.
Advanced Nutrients Cultivator Series Grow is a professional soluble powder nutrient designed to work alongside Cultivator Series Base during vegetative growth. Rather than transporting and storing large volumes of liquid concentrate, growers can accurately weigh the dry powder as required and dissolve it into their nutrient solution.
Cultivator Series has been developed with larger and more technically managed growing environments in mind, but its straightforward mixing rate also makes the 1kg bag practical for smaller growers who want the efficiency and control of a professional powdered nutrient programme.
Grow is not intended to be used as a standalone complete feed. During vegetative growth it is combined with Cultivator Series Base, with both components contributing to the final nutrient profile supplied to the crop.
Why choose Advanced Nutrients Cultivator Series Grow?
- Professional water-soluble powder – concentrated dry nutrition that is easy to store, transport, measure and mix.
- Designed for vegetative growth – the Grow component of the three-part Cultivator Series base nutrient programme.
- Used with Cultivator Series Base – both components work together during the vegetative phase.
- Highly concentrated format – avoids the need to store and handle equivalent volumes of liquid concentrate.
- Consistent dosing – dry powder can be accurately weighed for repeatable nutrient preparation.
- Suitable for hydroponics – developed for professional nutrient management and continuous liquid-feed systems.
- Coco coir safe – suitable for growers running Cultivator Series in coco-based production.
- Scalable nutrient programme – the same system can be used across smaller reservoirs and much larger commercial fertigation programmes.
What is Cultivator Series Grow suitable for?
Cultivator Series Grow is intended for the vegetative phase, when plants are establishing and developing their main root, leaf and structural growth before flowering.
It is used together with Cultivator Series Base rather than on its own. This two-component vegetative combination forms part of the wider three-part Cultivator Series programme, with Cultivator Series Bloom used as the crop moves into flowering.
Advanced Nutrients identifies the Cultivator Series for indoor and outdoor production, regular watering, watering systems, hydroponics and coco coir. Its soluble powder format is particularly useful where accurate, repeatable nutrient preparation and efficient storage are priorities.
How to use Cultivator Series Grow
During vegetative growth, use Cultivator Series Grow together with Cultivator Series Base. Advanced Nutrients' current Cultivator Series programme specifies 4g per US gallon of Grow and 4g per US gallon of Base.
For UK growers, this is approximately 1.06g/L of Grow and 1.06g/L of Base. As a practical metric guide, this works out at approximately 10.6g of each component for 10L, 52.8g of each for 50L and 105.7g of each for 100L.
Measure each powder accurately and dissolve it thoroughly into the water. Do not combine concentrated dry fertilisers together before dilution. Each component should be properly dispersed in the nutrient solution as part of the complete Cultivator Series programme.
As the crop moves from vegetative growth into flowering, follow the Cultivator Series flowering programme rather than continuing the vegetative Grow and Base combination unchanged.

Quick-dissolving microbial tablets delivering beneficial bacteria and fungi directly to the root zone to support root development and efficient nutrient uptake.
Advanced Nutrients Voodoo Juice Plus combines 16 strains of beneficial bacteria and fungi in a convenient tablet format. Designed as a microbial root-zone treatment, it brings together the microorganisms associated with Voodoo Juice, Piranha and Tarantula in one easy-to-dose product.
Once introduced to the nutrient solution, these beneficial microorganisms colonise the root zone and support the biological processes involved in root development, nutrient availability and nutrient absorption. Mycorrhizal fungi also extend through the root zone as mycelial networks, increasing the area from which nutrients can be accessed.
The tablet format is particularly useful for hydroponic and irrigation systems because there is no need to measure several separate liquid microbial products. Simply calculate the required tablet quantity for the volume of water being treated and allow it to dissolve into the nutrient solution.
Why choose Advanced Nutrients Voodoo Juice Plus?
- 16 microbial strains – combines beneficial bacteria and fungi selected to work within the plant root zone.
- Supports root development – encourages a larger, more biologically active root environment capable of supporting vigorous plant growth.
- Improves nutrient access – beneficial microorganisms help roots access and utilise nutrients within the growing environment.
- Contains mycorrhizal fungi – helps establish mycelial networks that extend beyond the immediate root surface.
- 10 billion CFUs per 1g tablet – provides a concentrated population of beneficial microorganisms in a compact format.
- Quick-dissolving tablets – removes the need to measure several separate liquid microbial additives.
- Suitable for hydroponics and coco – developed for soilless growing and liquid-feed systems.
- Works with irrigation systems – suitable for aeroponics, drip irrigation, NFT, flood and drain and deep water culture.
- Compatible with different base nutrients – designed for use alongside Advanced Nutrients pH Perfect and non-pH Perfect base nutrients as well as other nutrient programmes.
What is Voodoo Juice Plus used for?
Voodoo Juice Plus is used to introduce a diverse population of beneficial microorganisms into the root zone. Rather than supplying the plant with its primary mineral nutrition, it works alongside the base nutrient programme to improve the biological environment surrounding the roots.
It is particularly useful during periods when establishing an active root system is important, including early vegetative development and following changes in crop stage or growing conditions. It can also be incorporated during flowering where continued root-zone biological activity forms part of the feeding programme.
Advanced Nutrients designed Voodoo Juice Plus for hydroponic growing media and continuous liquid-feed systems, including aeroponics, drip irrigation and emitters, NFT, flood and drain and deep water culture. It is also suitable for coco and regular watering programmes.
How to use Advanced Nutrients Voodoo Juice Plus
For the 1g tablet format, Advanced Nutrients specifies one tablet for up to 100 US gallons of nutrient solution.
Converted into UK-friendly metric measurements, this is approximately one 1g tablet per 379 litres of water.
The tablets can be divided when treating smaller reservoirs. As a practical guide, approximately half a tablet treats 190 litres and quarter of a tablet treats around 95 litres.
Add the required amount directly to the nutrient reservoir and allow it to dissolve, ensuring the solution is adequately circulated or mixed.
Voodoo Juice Plus is best incorporated when establishing strong root-zone microbial activity, particularly during early vegetative development and around the transition into active flowering. The exact duration of use should reflect the crop, production cycle and feeding programme rather than a fixed number of weeks.
For dosing systems, Voodoo Juice Plus can also be prepared as a concentrated microbial stock solution. Keep microbial stock solutions agitated with a recirculating pump and use the prepared solution promptly.

A professional two-part water-soluble powder base nutrient formulated to deliver precise mineral nutrition during active flowering.
Advanced Nutrients Sensi Bloom A+B Pro is a concentrated two-part dry base nutrient developed for the flowering phase. Part A and Part B provide complementary mineral profiles that work together to create a complete bloom-focused nutrient solution.
Sensi Bloom Part A has an NPK analysis of 10-14-26, while Part B is 17-0-6. The two components are designed to be used together, supplying a carefully balanced combination of mineral nutrients as plants move into active flowering and generative development.
The water-soluble powder format makes Sensi Bloom A+B Pro particularly practical for precision feeding and larger nutrient reservoirs. It can be incorporated into hydroponic, coco and irrigation-based growing systems where accurate, repeatable nutrient preparation is important.
Why choose Advanced Nutrients Sensi Bloom A+B Pro?
- Flowering-stage base nutrition – formulated around the changing mineral requirements of plants as they enter active flowering.
- Professional two-part system – Parts A and B provide complementary nutrient profiles designed to be used together.
- Water-soluble powder – concentrated dry fertiliser designed to dissolve into the nutrient solution.
- Part A 10-14-26 – provides a phosphorus and potassium-rich component of the bloom feeding programme.
- Part B 17-0-6 – complements Part A with a distinct nitrogen and potassium profile.
- Equal-part application – Parts A and B are applied at the same rate when preparing the complete nutrient solution.
- Suitable for precision feeding – ideal for growers who want accurate control over nutrient preparation.
- Suitable for hydroponics and coco – designed for use across professional soilless growing systems.
- Irrigation-friendly format – the soluble formulation can be incorporated into irrigation-based feeding programmes.
What is Sensi Bloom A+B Pro used for?
Sensi Bloom A+B Pro is the flowering-stage base nutrient within the Advanced Nutrients Sensi Professional Series WSP programme. It takes over from the vegetative Grow A+B formulation as plants move into flowering and require a different balance of mineral nutrition.
Rather than treating flowering as a fixed number of weeks, Sensi Bloom A+B Pro can be incorporated according to the development of the crop. Use it during the active flowering phase, adapting the length of the feeding period to the species, cultivar and production cycle.
The two components have deliberately different nutrient analyses and are designed to work as a pair. Part A and Part B should therefore be used together rather than as independent fertilisers.
Its concentrated powder format makes Sensi Bloom A+B Pro suitable for everything from smaller controlled growing systems to commercial irrigation programmes where repeatable nutrient preparation and efficient storage are important.
How to use Sensi Bloom A+B Pro
Advanced Nutrients specifies 3.1g per US gallon of Part A and 3.1g per US gallon of Part B in its Sensi Bloom feeding programme.
Converted into measurements more familiar to UK growers, this is approximately 0.82g of Part A + 0.82g of Part B per litre of water.
Useful metric mixing quantities are approximately 8.2g A + 8.2g B per 10L, 41g A + 41g B per 50L and 82g A + 82g B per 100L.
Begin with the required volume of water. Measure the appropriate amount of Part A and dissolve it thoroughly before introducing Part B. Add Part B separately and mix again until the nutrient solution is fully dissolved and evenly distributed.
Do not combine concentrated Part A and Part B powders together before dilution. Each component should be introduced separately to the water when preparing the nutrient solution.
Use Sensi Bloom A+B during active flowering, adapting the duration of the feeding period to the crop and its production cycle. As the crop reaches its finishing stage, adjust or conclude the feeding programme according to crop requirements and the chosen cultivation strategy.

A professional 2-9-24 water-soluble Grow nutrient for high-volume vegetative feeding with the Advanced Nutrients Cultivator Series three-part system.
Advanced Nutrients Cultivator Series Grow is the vegetative component of a professional three-part water-soluble powder nutrient programme. During vegetative development, Grow is combined with Cultivator Series Base to provide the nutrient profile required for vigorous crop establishment and structural growth.
The concentrated dry format is particularly useful for commercial growers preparing large volumes of nutrient solution. Instead of transporting and storing water-heavy liquid concentrates, Cultivator Series allows accurately weighed dry fertiliser to be dissolved as required, helping simplify storage, handling and large-scale fertigation.
This 10kg format is one of the pack sizes specifically offered by Advanced Nutrients for the European market. It is aimed squarely at growers who need a scalable nutrient programme for larger reservoirs, irrigation systems and repeat production cycles.
Why choose Advanced Nutrients Cultivator Series Grow?
- Professional 2-9-24 formulation – the Grow component of the current Advanced Nutrients Cultivator Series.
- Designed for vegetative growth – used with Cultivator Series Base during crop establishment and active vegetative development.
- Water-soluble powder – concentrated dry nutrition designed to dissolve into the irrigation solution.
- Commercial 10kg format – well suited to larger growing areas, frequent reservoir preparation and professional fertigation.
- Accurate dry dosing – weigh the required amount for consistent, repeatable nutrient preparation.
- Efficient storage – concentrated powder avoids storing and transporting the water contained in conventional liquid nutrient concentrates.
- Hydroponic & coco compatible – designed for diverse hydroponic media and continuous liquid-feed growing systems.
- Scalable three-part system – developed to integrate into professional growing programmes where nutrient ratios change with crop stage.
What is Cultivator Series Grow suitable for?
Cultivator Series Grow is used during propagation establishment and vegetative development as part of the Cultivator Series base nutrient programme. It is combined with Cultivator Series Base rather than being used as a standalone complete feed.
The 10kg format is particularly suitable for commercial growers, larger indoor growing facilities and horticultural operations preparing substantial volumes of nutrient solution. Its dry format makes it easier to store significant quantities of concentrated fertiliser without the bulk associated with equivalent liquid feeds.
Advanced Nutrients identifies Cultivator Series as suitable for indoor and outdoor growing, regular watering, watering systems, hydroponics and coco coir. It is also designed for 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 Cultivator Series Grow
During vegetative growth, use Cultivator Series Grow together with Cultivator Series Base. The current Advanced Nutrients programme specifies 4g per US gallon of Grow and 4g per US gallon of Base.
Converted for UK growers, this is approximately 1.06g/L of Grow and 1.06g/L of Base. For practical reservoir preparation, use approximately 10.6g of each component for 10L, 52.8g of each for 50L or 105.7g of each for 100L.
For larger commercial reservoirs, approximately 528g of Grow and 528g of Base are required for 500L, or approximately 1.06kg of Grow and 1.06kg of Base for 1,000L, based on the manufacturer's 4g per US gallon rate.
Accurately weigh each fertiliser component and dissolve it thoroughly into the water. Do not combine concentrated dry fertiliser components together before dilution. Each component should be introduced and properly dissolved as part of the complete nutrient preparation process.
When the crop moves from vegetative development into flowering, change to the appropriate Cultivator Series Base and Bloom programme rather than continuing the vegetative Grow and Base combination.

A concentrated 14-0-0 water-soluble Base nutrient supplying nitrogen, calcium and chelated iron throughout the Advanced Nutrients Cultivator Series programme.
Advanced Nutrients Cultivator Series Base is the foundation component of the three-part Cultivator Series water-soluble nutrient system. Unlike Grow and Bloom, which are used at different stages, Base remains part of the feeding programme across both vegetative growth and flowering.
Its 14-0-0 analysis is backed by 17% calcium and 0.32% chelated iron. This gives Base a clearly defined role within the three-part programme, complementing Cultivator Series Grow during vegetative development and Cultivator Series Bloom once the crop moves into flowering.
The current Cultivator Series Base formulation has been updated with pharmaceutical-grade chelated iron for improved micronutrient precision and cleaner, sediment-free reservoir performance. The newer formulation may also have a golden appearance rather than the red colour associated with earlier versions.
Why choose Advanced Nutrients Cultivator Series Base?
- 14-0-0 base formulation – supplies the nitrogen component required across the Cultivator Series programme.
- 17% calcium – provides a substantial calcium contribution as part of the complete three-part nutrient system.
- 0.32% chelated iron – supplies iron in a chelated form for effective micronutrient delivery.
- Updated iron technology – the current formulation uses pharmaceutical-grade chelated iron for improved micronutrient precision.
- Cleaner reservoir performance – the updated Base has been developed to improve mixability and reduce sediment in nutrient reservoirs.
- Used through grow & bloom – combines with Grow during vegetative development and Bloom during flowering.
- Water-soluble powder – concentrated dry nutrition for accurate weighing, efficient storage and repeatable nutrient preparation.
- Hydroponic & coco compatible – suitable for a wide range of growing media and continuous liquid-feed systems.
What is Cultivator Series Base suitable for?
Cultivator Series Base is designed to be used throughout the main feeding programme rather than being restricted to either vegetative growth or flowering.
During vegetative development it is paired with Cultivator Series Grow. As plants move through transition and into flowering, Grow is replaced by Cultivator Series Bloom while Base remains part of the programme. Its application rate is then progressively reduced as the crop moves through active and later flowering.
Advanced Nutrients identifies Cultivator Series as suitable for indoor and outdoor growing, regular watering, watering systems, hydroponics and coco coir. It is specifically designed for 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 Cultivator Series Base
During vegetative development, use Cultivator Series Base at 4g per US gallon alongside Cultivator Series Grow at the same rate. For UK growers, 4g per US gallon converts to approximately 1.06g/L of each component.
During transition and early flowering, continue Base at 4g per US gallon, approximately 1.06g/L, alongside Cultivator Series Bloom.
As the crop moves into active flowering, the Cultivator Series programme reduces Base to 3g per US gallon, approximately 0.79g/L, while increasing the proportion of Bloom.
During later flowering, Base is reduced again to 2g per US gallon, approximately 0.53g/L, before being withdrawn as the crop reaches the final finishing stage.
Accurately weigh the required quantity and dissolve Base thoroughly into water. Do not combine concentrated Cultivator Series powders together before dilution. Each component should be introduced and properly dissolved as part of the complete nutrient preparation process.

Not usually. Cultivator Series is designed to work across a range of water sources, including many tap water and reverse osmosis setups, and Advanced Nutrients states that additional Cal-Mag is unnecessary in the vast majority of cultivation environments. Source water, growing medium and crop conditions should still form part of professional nutrient management.

A commercial 14-0-0 water-soluble Base nutrient supplying nitrogen, calcium and chelated iron throughout the Advanced Nutrients Cultivator Series programme.
Advanced Nutrients Cultivator Series Base is the foundation component of the three-part Cultivator Series dry nutrient system. It works alongside Cultivator Series Grow during vegetative development, then remains in the programme alongside Cultivator Series Bloom as crops move through flowering.
The concentrated 10kg powder format is particularly well suited to commercial cultivation, larger reservoirs and regular fertigation preparation. Growers can weigh exactly what is required for each batch, while avoiding the storage and transport associated with equivalent volumes of liquid concentrate.
The current Base formulation uses pharmaceutical-grade chelated iron for improved micronutrient precision and cleaner reservoir performance. Advanced Nutrients notes that the updated powder can appear golden rather than the red colour associated with earlier versions.
Why choose Advanced Nutrients Cultivator Series Base?
- 14-0-0 base formulation – provides the nitrogen-rich foundation of the Cultivator Series feeding programme.
- Calcium-rich formulation – supplies calcium alongside nitrogen and iron as part of the complete three-part system.
- EDTA-chelated iron – the current formulation supplies 0.32% chelated iron for precise micronutrient delivery.
- Updated iron technology – Advanced Nutrients now uses pharmaceutical-grade chelated iron in Cultivator Series Base.
- Cleaner reservoir performance – the updated formulation is designed for cleaner mixing with reduced sediment.
- Used through grow & bloom – combines with Grow during vegetative development and Bloom during flowering.
- Commercial 10kg format – ideal for larger reservoirs, intensive production and repeated fertigation preparation.
- Water-soluble powder – concentrated dry nutrition that can be accurately weighed for consistent batch preparation.
- Hydroponic & coco compatible – suitable for a wide range of continuous liquid-feed growing systems.
What is Cultivator Series Base suitable for?
Cultivator Series Base is designed for use across both vegetative growth and flowering. Unlike Grow and Bloom, which take different roles as the crop develops, Base remains part of the programme across the main feeding cycle.
During vegetative development, Base is paired with Cultivator Series Grow. At transition into flowering, the programme changes to Base plus Cultivator Series Bloom. The amount of Base is then progressively reduced as flowering advances and the nutritional balance shifts towards Bloom.
The 10kg bag is particularly useful for commercial growers and larger horticultural facilities where substantial quantities of nutrient solution are prepared regularly. Advanced Nutrients identifies Cultivator Series as suitable for indoor and outdoor production, coco coir, hydroponics, regular watering and continuous liquid-feed systems.
How to use Cultivator Series Base
During vegetative development, use Cultivator Series Base at 4g per US gallon alongside Cultivator Series Grow at the same rate. Converted for UK growers, this is approximately 1.06g/L of Base and 1.06g/L of Grow.
During transition and early flowering, Base continues alongside Cultivator Series Bloom. As flowering progresses, follow the Cultivator Series programme and progressively reduce the Base component to match the changing nutritional requirements of the crop.
At the 4g per US gallon rate, use approximately 105.7g for 100L, 528g for 500L or 1.06kg for 1,000L of nutrient solution.
Accurately weigh the required powder and dissolve it thoroughly into water. Do not combine concentrated Cultivator Series powders together before dilution. Each component should be added to water and properly dissolved as part of the complete nutrient preparation process.

Advanced Nutrients Cultivator Series Base FAQs
What is Advanced Nutrients Cultivator Series Base?
Cultivator Series Base is the 14-0-0 foundation component of Advanced Nutrients' three-part water-soluble powder nutrient system. It is paired with Cultivator Series Grow during vegetative development and Cultivator Series Bloom during flowering.
What is the NPK of Cultivator Series Base?
Advanced Nutrients specifies Cultivator Series Base as 14-0-0.
Does Cultivator Series Base contain calcium?
Yes. The European technical analysis specifies 23.7% water-soluble calcium oxide (CaO), alongside the nitrogen and chelated iron in the Base formulation.
Does Cultivator Series Base contain chelated iron?
Yes. The current formulation contains 0.32% EDTA-chelated iron. Advanced Nutrients has also updated Cultivator Series Base to use pharmaceutical-grade chelated iron for improved micronutrient precision and cleaner reservoir performance.
Why can Cultivator Series Base look golden instead of red?
Advanced Nutrients states that the updated Base powder may appear golden rather than the red colour seen in previous versions. This is associated with the updated chelated iron formulation and is not an indication that the product is incorrect.
Is Cultivator Series Base used with Grow or Bloom?
Both. Use Base with Cultivator Series Grow during vegetative development, then with Cultivator Series Bloom once the crop moves into flowering.
Is Cultivator Series Base a standalone fertiliser?
No. Base is one component of the three-part Cultivator Series nutrient programme and is designed to work with the corresponding Grow or Bloom component according to crop stage.
How much Cultivator Series Base should I use during vegetative growth?
Advanced Nutrients specifies 4g per US gallon of Base alongside 4g per US gallon of Grow during vegetative development. This converts to approximately 1.06g/L of each component.
How much Cultivator Series Base do I need for 100 litres?
At 4g per US gallon, use approximately 105.7g of Cultivator Series Base for 100 litres of nutrient solution.
How much Cultivator Series Base do I need for a 500L reservoir?
At the 4g per US gallon rate, a 500L reservoir requires approximately 528g of Cultivator Series Base.
How much Cultivator Series Base do I need for 1,000 litres?
At 4g per US gallon, use approximately 1.06kg of Cultivator Series Base for 1,000 litres of nutrient solution.
Can Cultivator Series Base 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 Base be used in coco?
Yes. Advanced Nutrients specifically identifies Cultivator Series as coco coir safe.
Do I automatically need Cal-Mag with Cultivator Series?
Not in most growing environments. Cultivator Series is designed for use across a range of source-water conditions, including many tap-water and reverse-osmosis setups. Additional calcium and magnesium should therefore be based on the actual source water, growing medium and crop requirements rather than being added automatically.
Is the 10kg Cultivator Series Base suitable for commercial growing?
Yes. The concentrated 10kg powder format is particularly useful for commercial horticulture, larger reservoirs and growing facilities that prepare substantial volumes of nutrient solution on a regular basis.
