Advanced Nutrients -- pH Perfect Base Nutrients & Additives
Advanced Nutrients is one of the most recognized premium nutrient brands in North American indoor growing, best known for their pH Perfect technology -- a proprietary buffering system built into their base nutrient formulas that claims to automatically maintain pH within the optimal range without manual pH adjustment. Their product lineup spans base nutrients, bloom boosters, and a comprehensive additive system covering root stimulants, micronutrient supplements, carbohydrate additives, and beneficial bacteria products, all designed to work as an integrated system.
pH Perfect Technology
Advanced Nutrients' pH Perfect base nutrients (Sensi Grow A&B and Sensi Bloom A&B) contain amphoteric compounds that buffer pH automatically toward the 5.5-6.5 range when mixed in most tap and RO water at the recommended dosing rate. For growers who struggle with pH management or want to simplify their nutrient program, pH Perfect removes the daily pH adjustment requirement when the system is functioning correctly -- mix at the recommended rate and the formula buffers to the target range automatically. This buffering is effective within a certain input water pH range; very hard or very soft water at extremes may still require manual adjustment. Verify with a calibrated pH meter when setting up any new Advanced Nutrients program.
Advanced Nutrients Base Nutrients & Additives
The Sensi Grow A&B (vegetative) and Sensi Bloom A&B (flowering) two-part base nutrients are the foundation of the Advanced Nutrients system. Their additive line includes Big Bud (PK bloom booster), Bud Candy (carbohydrate supplement), Tarantula and Piranha (beneficial bacteria and fungi for root zone health), and B-52 (B vitamin supplement). All are formulated to work within the Advanced Nutrients pH Perfect program, though most additives are also compatible with other base nutrient programs at appropriate dosing rates.

Advanced Nutrients FAQ
Does Advanced Nutrients pH Perfect actually work?
pH Perfect technology works effectively within its designed parameters -- when mixing at the recommended rate with most tap and RO water sources, the buffering compounds maintain solution pH in the 5.5-6.5 range without manual adjustment in most cases. Growers who have switched to Advanced Nutrients report meaningful reductions in pH management time. Limitations: the buffering is not infinite -- very hard alkaline tap water (above 400-500 ppm TDS) may overwhelm the buffer and still require manual pH Down; and the system works best at the manufacturer's recommended mixing ratios, not at reduced rates. Always verify pH with a calibrated meter when starting a new batch or changing water sources.
How does Advanced Nutrients compare to General Hydroponics?
Both are complete synthetic nutrient programs suitable for hydroponic, coco, and soil growing. GH FloraSeries is the more affordable, more widely documented option with the largest body of community grow guides and troubleshooting resources -- the default recommendation for first-time growers. Advanced Nutrients is a premium-tier program with the pH Perfect convenience feature and a more comprehensive additive ecosystem. Advanced Nutrients typically costs more per gallon of final solution than GH. For experienced growers who want to minimize pH management time and use a comprehensive integrated additive system, Advanced Nutrients is a well-justified choice. For growers prioritizing cost and community support, GH FloraSeries is the more practical option.
Can I use Advanced Nutrients additives with other base nutrients?
Most Advanced Nutrients additives (Big Bud, Bud Candy, B-52) are compatible with other base nutrient programs at appropriate dosing rates -- they are nutrient and carbohydrate supplements that function independently of the base program's chemistry. The pH Perfect buffering in the Sensi base nutrients is specific to the Advanced Nutrients base formula and does not transfer to other base nutrients when additives are mixed into a different base program. When using AN additives with non-AN base nutrients, manual pH management is still required as normal.
What is the Advanced Nutrients Sensi Grow and Sensi Bloom program?
Sensi Grow A&B is a two-part base nutrient for the vegetative growth stage -- Part A and Part B are kept separate in concentrate and mixed together in the reservoir. Sensi Bloom A&B is the two-part formula for flowering, with a different NPK ratio that favors phosphorus and potassium for flower development. Both incorporate pH Perfect buffering technology. The standard program is: use Sensi Grow for vegetative growth from seedling through pre-flowering transition, then switch to Sensi Bloom when flowering is initiated. Add pH Perfect Micro as the foundation if running the three-part version of the program.
How much Advanced Nutrients should I use per gallon?
Advanced Nutrients recommends 4 ml per liter (approximately 15 ml per gallon) of each Sensi part (A and B separately) as a standard starting rate -- resulting in approximately 30 ml combined per gallon total. This produces an EC of approximately 1.5-2.0 mS/cm depending on your water's baseline TDS. Adjust from this starting point based on your EC meter readings and plant response. The pH Perfect buffering functions most reliably at these recommended dosing rates; significantly reducing the dose below recommended levels may reduce the buffering effectiveness.
