Advanced Nutrients Sensi Grow A&B — Two-Part Hydroponic Base Nutrients with pH Perfect Technology
Best for: Growers wanting straightforward vegetative nutrition without manual pH adjustment or endless mixing schedules
Our thoughts
Sensi Grow does what a base nutrient should do — keeps plants fed properly through the growth phase without requiring a chemistry degree. The pH Perfect tech is genuinely useful if you follow the label properly. One of the most reliable two-part systems we stock, and growers keep coming back to it.
Advanced Nutrients Sensi Grow A&B is a complete two-part base nutrient system designed for the vegetative stage of hydroponic growing. Mix equal amounts of Part A and Part B, and you've got all 16 essential nutrients — macro, secondary, and micronutrients — ready to feed your plants without additional base nutrients. The real draw here is the pH Perfect technology, which keeps your nutrient solution stable within the optimal range for a full week, eliminating the need for constant pH testing and adjustment.
It contains amino acid complexes for better nutrient uptake, humic and fulvic acids for improved nutrient transport, and wetting agents that help roots absorb everything more efficiently. This is proper plant nutrition at a straightforward price point — no guesswork, no complicated mixing charts, just two bottles and a measuring jug.
How it compares
Sensi Grow occupies the accessible premium tier of two-part hydroponic nutrients.
-
vs. General Hydroponics Flora Series: Flora is 3-part, giving you granular control; Sensi is 2-part with automatic pH — simpler, less flexible, but quicker to dial in
-
vs. Budget two-part systems: You're paying for the pH Perfect tech and amino acid blend — saves money on pH testing equipment and adjustments over time
-
vs. Advanced Nutrients Connoisseur: Connoisseur is the premium tier; Sensi is the sensible choice if you want quality without the top-shelf price
Bottom line: you get professional-grade nutrition with built-in pH stability. That's worth paying for.
Usage guidance
Sensi Grow works across all hydroponic systems — NFT, flood and drain, deep water culture, drip irrigation, aeroponics. The approach is identical across all of them.
Standard feeding (established plants)
Use 4ml per litre during all vegetative weeks. Mix Part A into your water first, stir thoroughly, then add Part B and stir again. This prevents nutrients from locking out before they reach the roots.
Young plants (3–4 sets of leaves)
Use 2ml per litre until they're established enough for full strength.
Cuttings and seeds
Use 1ml per litre — gentle feeding while roots develop.
Important: pH Perfect only works if you stick to the rules
The technology relies on using only Advanced Nutrients products in your tank. Mix in third-party boosters or additives and the pH buffering stops working. Use RO water or soft water — hard tap water can interfere with the system. If you're committed to the Advanced Nutrients ecosystem, you're golden. If you want to blend and match products from different brands, this isn't your nutrient.
When to change
The pH remains stable for one week. After that, do a partial or full reservoir change depending on your system type.

Who this is for
- Hydroponic growers tired of faffing with pH metres and buffers week after week
- Growers stepping up from basic nutrients to something with more mineral backbone and amino acid support
- Anyone running multiple systems where saving 10 minutes per week on pH adjustment adds up
- Growers committed to the Advanced Nutrients product family (and getting full value from pH Perfect)
- First-time hydroponic growers wanting proven, reliable nutrition that removes one major complication
Our take
Sensi Grow is a solid, no-nonsense base nutrient that does exactly what it should do — feeds plants properly and keeps them stable without daily tweaking. The pH Perfect tech genuinely works, as long as you follow the label and stick with Advanced Nutrients additives.
If pH management is slowing you down or you're fed up with probe calibration, this removes that headache. It's a straightforward vegetative nutrition system that's proven to work, backed by a brand that's been making hydroponic nutrients for decades. Good time to pick up while clearance stock lasts.
