Advanced Nutrients Connoisseur Bloom A&B — Premium 2-Part Bloom Nutrient with Automatic pH Control
Best for: Experienced growers running hydroponic systems who've mastered the basics and want to squeeze every last gram of yield and quality from the flowering phase
Our thoughts
This is the top-tier choice if you know what you're doing. Connoisseur sits above Sensi Bloom — it's more concentrated, more finely tuned, and backed by serious science. Not an entry point, but if you've already dialed in your environment and want to push yields higher, this is where the money goes.
Advanced Nutrients Connoisseur Bloom A&B is a premium 2-part bloom nutrient designed exclusively for the flowering phase of hydroponic growing. Built by a research team of 21 PhD scientists, it combines a carefully balanced macro and micronutrient formula with Advanced Nutrients' proprietary pH Perfect technology — which means the nutrient automatically regulates pH within the optimal range, eliminating the guesswork and daily pH adjustments. This is a concentrate-strength formula that's approximately 25% stronger than standard competitors, delivering intense fruiting, maximum yield weight, and elevated essential oil and aroma production.
How it compares
Connoisseur Bloom sits at the absolute top of the 2-part bloom nutrient tree.
-
vs Sensi Bloom A&B: Both use pH Perfect technology, but Connoisseur is more concentrated and scientifically refined for maximum results. Sensi is the more forgiving entry to the pH Perfect range; Connoisseur is the flagship for serious yields.
-
vs General Hydroponics Flora Series (3-part): Flora gives you more granular control over individual nutrients; Connoisseur is pre-balanced for bloom and handles pH automatically. Different philosophies — Flora suits growers who want to dial every detail; Connoisseur suits those who want proven science to do the heavy lifting.
-
vs CANNA Flores A&B: Both are premium 2-part systems. Connoisseur's pH Perfect tech is the differentiator — you're paying for automatic pH management built into the formula itself.
-
2-part advantage: The separation of Part A and Part B allows minerals that would otherwise bind together in the bottle to remain fully available to your plants. This means more micronutrients in the solution and faster uptake.
Usage guidance
Connoisseur Bloom A&B is designed for all continuous liquid-feed hydroponic systems:
Dosage
Mix at 4 ml/L — use equal volumes of Part A and Part B. Always add Part A first to your reservoir, then follow with Part B. Do not add both parts in concentrated form.
Hydroponic systems (aeroponics, drip irrigation, NFT, flood and drain, deep water culture)
Connoisseur is built for these setups. The 2-part formulation and pH Perfect technology work cleanly in recirculating and run-to-waste systems. Change reservoir every 2 weeks for optimal nutrient stability.
Hand watering (coco or inert media)
Can be used, but designed primarily for automated hydro. If hand watering, maintain consistent EC and allow proper drainage.
Nutrient strength and environment
This is a complete bloom formula — you need a properly dialled-in growing environment (temperature, humidity, CO₂, light) to get the results Connoisseur is designed for. If your basics aren't locked in, you won't see the difference. This product rewards attention to detail.
Complementary products
Connoisseur Bloom pairs with Advanced Nutrients' additives like Big Bud, B-52, and Overdrive to complete the full nutrient and enhancement range.

Who this is for
- Experienced hydroponic growers with at least 1+ year of proven growing success
- Growers running established, dialled-in growing environments (temperature, humidity, CO₂, lighting all controlled)
- Serious and commercial operators looking to maximise final yield weight and quality
- Growers who've already mastered other pH Perfect nutrient ranges and want to step up
- Anyone running aeroponics, drip irrigation, NFT, flood and drain, or deep water culture systems
- Growers who value time-saving automation (automatic pH regulation) in their feeding routine
Not suited to: First-year growers, those still establishing growing fundamentals, or growers struggling to dial in their environment. Connoisseur rewards mastery — it's not a solution for basic issues.
Our take
This is the premium choice for growers who've already got everything else dialled in. pH Perfect Connoisseur removes one major daily headache — pH management — and puts scientifically-advanced nutrition into your reservoir. You're not paying for hype; you're paying for concentrate strength, research backing, and automation that saves time on established, professional grows.
It's not the entry point to advanced nutrients. But if you've already mastered pH management, environmental control, and feeding precision, and you want to take final yields and quality to the next level, this is worth the investment. Good time to buy while stock lasts.
