£59.95

A two-part vegetative base nutrient combining balanced plant nutrition with pH Perfect technology for straightforward feeding throughout establishment and active vegetative growth.

Advanced Nutrients pH Perfect Sensi Grow A+B is a two-part base nutrient formulated for the vegetative stage. Parts A and B work together to supply the macro, secondary and micronutrients required as young plants establish and develop into vigorous vegetative growth.

The formula provides targeted levels of iron and sulphur to support nitrogen uptake, alongside highly effective chelation that helps keep essential nutrients available to the crop. A non-ionic surfactant further supports nutrient delivery throughout the root zone.

Advanced Nutrients' pH Perfect technology is designed to manage nutrient-solution pH automatically when the product is used as directed, simplifying reservoir preparation and reducing the need for routine pH adjustment.

Why choose pH Perfect Sensi Grow A+B?

  • Complete two-part vegetative base nutrient – Parts A and B provide complementary nutrition throughout the grow phase.
  • pH Perfect technology – designed to manage nutrient-solution pH automatically when mixed and used as directed.
  • Stage-responsive feeding – application strength increases progressively from establishment through active vegetative development.
  • Supports nitrogen uptake – formulated with targeted levels of iron and sulphur for vigorous vegetative growth.
  • Advanced chelation – helps keep essential nutrients readily available for root uptake.
  • Non-ionic surfactant – supports effective nutrient distribution around the root zone.
  • Suitable for hydroponics and coco – developed for a broad range of soilless media and continuous liquid-feed systems.
  • Suitable for indoor and outdoor growing – works across a wide range of controlled and conventional cultivation environments.

What is pH Perfect Sensi Grow A+B suitable for?

Sensi Grow A+B is designed for the vegetative portion of the crop cycle, beginning at establishment and increasing progressively as root mass, foliage and overall plant demand develop.

It is particularly well suited to hydroponic and coco cultivation and can be used with regular watering or automated irrigation. Compatible liquid-feed systems include aeroponics, drip irrigation and emitters, nutrient film technique (NFT), flood and drain and deep water culture (DWC).

Once the crop moves from vegetative development into its flowering phase, the corresponding pH Perfect Sensi Bloom A+B provides the flowering-stage base nutrition.

How to use pH Perfect Sensi Grow A+B

Shake both containers thoroughly before use. Add Part A to the required volume of water and mix thoroughly, then add Part B at the same rate and mix again. Never combine the concentrated Part A and Part B products together before dilution.

During propagation and early establishment, begin at 1ml/L of Part A plus 1ml/L of Part B. Increase to approximately 2ml/L of each part as young plants establish, then 3ml/L of each part as vegetative demand increases. Established plants can be fed at up to 4ml/L of Part A plus 4ml/L of Part B.

For a 10L nutrient solution, this equates to 10–40ml of Part A and the same amount of Part B depending on crop stage. For 50L, use 50–200ml of each part, and for 100L use 100–400ml of each part.

These rates apply to each component separately. A rate of 4ml/L therefore means 4ml/L of Part A and 4ml/L of Part B, not 4ml/L divided between the two products.

Advanced Nutrients pH Perfect Sensi Grow A+B FAQs

What is pH Perfect Sensi Grow A+B?

Sensi Grow A+B is a two-part base nutrient formulated by Advanced Nutrients for establishment and vegetative growth. Parts A and B supply complementary nutrition and are used together throughout the grow phase.

How much Sensi Grow A+B should I use per litre?

Start at 1ml/L of Part A plus 1ml/L of Part B during propagation and establishment. Increase progressively through 2ml/L and 3ml/L of each part as plants develop, reaching up to 4ml/L of each part during established vegetative growth.

How much Sensi Grow A+B do I need for 10 litres?

Depending on crop stage, use 10–40ml of Part A plus 10–40ml of Part B for every 10 litres of nutrient solution.

Do I use Sensi Grow Part A and Part B together?

Yes. Unlike the sequential Sensi Terra Part One and Part Two system, pH Perfect Sensi Grow is a true A+B nutrient. Both components are used at the same application rate throughout the vegetative feeding programme.

Can I mix Sensi Grow A and B concentrates together?

No. Add Part A to water first and mix thoroughly before adding Part B. The concentrated products should not be combined directly with one another before dilution.

What does pH Perfect mean?

pH Perfect is Advanced Nutrients' proprietary technology designed to manage nutrient-solution pH automatically when the nutrient programme is mixed and used as directed, reducing the need for routine manual pH adjustment.

What is the NPK of Sensi Grow A+B?

Advanced Nutrients lists Sensi Grow Part A as 3-0-0 and Part B as 1-2-6. The two components are formulated to work together rather than being treated as standalone fertilisers.

Can pH Perfect Sensi Grow be used in hydroponics?

Yes. It is formulated for hydroponic growing media and continuous liquid-feed systems including aeroponics, drip irrigation, NFT, flood and drain and deep water culture.

Can pH Perfect Sensi Grow be used in coco?

Yes. Advanced Nutrients lists the standard pH Perfect Sensi Grow and Bloom range as coco coir safe. A separate coco-specific variation is also available within the Sensi range.

When should I change from Sensi Grow to Sensi Bloom?

Sensi Grow A+B provides the base nutrition throughout vegetative development. Change to pH Perfect Sensi Bloom A+B as the crop moves into its flowering phase.
