Connoisseur Grow sits at the top of Advanced Nutrients' base nutrient range and it knows it. If you've mastered your environment, nailed your technique, and want to squeeze every last bit of performance from your setup, this is the nutrient system built for that. Not for beginners. Very much for growers who've already got results and want better ones.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eAdvanced Nutrients Connoisseur Grow A\u0026amp;B is a \u003cstrong\u003epremium two-part liquid nutrient system\u003c\/strong\u003e engineered for the vegetative growth phase in hydroponic and recirculating setups. This is the top-tier formulation from Advanced Nutrients — designed specifically for experienced growers who've already mastered the basics and are ready to unlock the full genetic potential of their plants.\u003c\/p\u003e\n\u003cp\u003eThe system uses Advanced Nutrients' proprietary \u003cstrong\u003epH Perfect Technology\u003c\/strong\u003e, which automatically adjusts your nutrient solution to the sweet spot of pH 5.5–6.3, regardless of your input water's acidity or alkalinity. That means no more pH drift, no daily monitoring, and one less variable to stress about — provided you're running it clean with other Advanced Nutrients products.\u003c\/p\u003e\n\u003cp\u003eBeyond pH stability, Connoisseur Grow contains a carefully balanced blend of amino acids (the building blocks of plant protein), humic and fulvic acids for enhanced nutrient transport, and chelated micronutrients that hit harder than standard formulations. The advanced wetting agents work to improve nutrient uptake across the board. All of this is designed to deliver vigorous, accelerated vegetative growth and set your plants up for maximum yields in the flowering stage.\u003c\/p\u003e\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eConnoisseur Grow sits at the \u003cstrong\u003epremium end\u003c\/strong\u003e of the two-part hydroponic nutrient market.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003evs. Advanced Nutrients Sensi Grow:\u003c\/strong\u003e Marginally superior formulation with higher concentration and premium ingredients, but real-world results are minimal for most growers. You're paying for the last 5–10% of performance and the research backing it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003evs. Canna Aqua\/Hydro A\u0026amp;B:\u003c\/strong\u003e Similar price tier, different chemistry.

Athena is simpler and appeals to a wider skill range; Connoisseur is deliberately pitched at the top tier only.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn plain terms: you're buying the flagship product from a Canadian nutrient powerhouse that's been refining formulations since 1999. The price reflects that investment.\u003c\/p\u003e\n\u003ch3\u003eUsage guidance\u003c\/h3\u003e\n\u003cp\u003eConnoisseur Grow works across multiple hydroponic systems — drip irrigation, flood and drain, NFT, aeroponic, and hand watering — but it's optimised for recirculating setups.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStandard dosage\u003c\/strong\u003e\u003cbr\u003eUse 4ml of Part A and 4ml of Part B per litre of water (or 4ml per gallon if you prefer imperial). This is the manufacturer recommendation. Some experienced growers run lighter at 2–2.5ml per litre and still get excellent results — dial in what works for your environment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMixing instructions\u003c\/strong\u003e\u003cbr\u003eAlways add Part A first, mix thoroughly, then add Part B. Never mix both parts in their concentrated form — you'll get nutrient lockout. Add them one at a time to your reservoir, stir well between each addition.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWater quality matters\u003c\/strong\u003e\u003cbr\u003epH Perfect Technology works best with RO (reverse osmosis) water or water below 100ppm EC. If your tap water is heavily mineralised, switch to RO — it's the difference between the system working cleanly and pH fighting against your input water.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003epH management\u003c\/strong\u003e\u003cbr\u003eOnce mixed with Connoisseur and other Advanced Nutrients products, your solution will naturally settle at pH 5.5–6.3. If you've added any other brand's nutrients to the mix, pH Perfect might not engage properly and you'll need to monitor manually. Keep it clean.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompanion products\u003c\/strong\u003e\u003cbr\u003eConnoisseur Grow pairs with Advanced Nutrients' specialty additives — Big Bud, B-52, Overdrive — to complete a full professional feeding regimen. Many growers add Big Bud from mid-veg onwards for structure and flowering potential.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCalcium-magnesium considerations\u003c\/strong\u003e\u003cbr\u003eSome growers report needing supplemental calcium and magnesium depending on medium and water type. If you see early deficiency signs, address via foliar feeding rather than adding to your reservoir — it keeps the pH Perfect system stable.\u003c\/p\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e Two-part liquid base nutrient (Part A + Part B)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNPK Ratio — Part A:\u003c\/strong\u003e 4-0-0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNPK Ratio — Part B:\u003c\/strong\u003e 1-2-7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey active ingredients:\u003c\/strong\u003e Amino acids, humic and fulvic acids, chelated micronutrients, advanced wetting agents\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epH adjustment:\u003c\/strong\u003e Automatic (pH Perfect Technology) — settles to 5.5–6.3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEC at recommended dose:\u003c\/strong\u003e Dependent on input water, typically 1.2–1.6 mS\/cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible systems:\u003c\/strong\u003e Hydroponic, aeroponic, drip irrigation, NFT, flood and drain, hand watering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended dosage:\u003c\/strong\u003e 4ml Part A + 4ml Part B per litre of water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable sizes:\u003c\/strong\u003e 1L and 4L bottles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage:\u003c\/strong\u003e Keep in cool, dark conditions; concentrate will last several years\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer guarantee:\u003c\/strong\u003e 100% Money-Back Grower Guarantee — if unsatisfied with results, return unused portion with receipt within 6 months for full refund\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWho this is for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eExperienced hydroponic growers with a minimum of 1–2 years active growing under their belt\u003c\/li\u003e\n\u003cli\u003eGrowers whose environments are already dialled in (lighting, humidity, temperature, air movement all locked down)\u003c\/li\u003e\n\u003cli\u003eAnyone running successful crops and wanting to push yields and quality further\u003c\/li\u003e\n\u003cli\u003eProfessional and commercial operations where maximising output justifies the premium cost\u003c\/li\u003e\n\u003cli\u003eGrowers comfortable with two-part nutrient systems and precise mixing protocols\u003c\/li\u003e\n\u003cli\u003eRO water users or those with low-EC tap water (pH Perfect works best in these conditions)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis is \u003cstrong\u003enot\u003c\/strong\u003e for first-year growers, those still troubleshooting environmental basics, or anyone looking to keep costs lean.

It's precisely formulated, backed by serious research, and designed for growers who've already proven they know what they're doing. The pH Perfect automation genuinely removes a headache from hydroponic growing, and the nutrient profile is noticeably richer than the cheaper Sensi alternative.\u003c\/p\u003e\n\u003cp\u003eThat said — and we'll be straight with you — if you're getting strong results from a mid-tier two-part system already, Connoisseur's gains are incremental. You're paying for the last few percentage points of performance and the peace of mind of running a flagship product. Worth it if you've got the environment and experience to make use of it. Not a shortcut to better results if the rest of your setup isn't already solid.\u003c\/p\u003e\n\u003cp\u003eGood time to stock up on premium base nutrients while clearance pricing lasts. If Connoisseur is your choice, you know what you're after.\u003c\/p\u003e\n\u003c\/section\u003e","brand":"ADVANCED NUTRIENTS","offers":[{"title":"1 Litre","offer_id":47916265767082,"sku":"91688","price":34.99,"currency_code":"GBP","in_stock":true},{"title":"5 Litre","offer_id":47916265799850,"sku":"3462","price":159.99,"currency_code":"GBP","in_stock":true},{"title":"10 Litre","offer_id":47916265832618,"sku":"91690","price":239.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0053\/5540\/5400\/files\/91688_-_connoissuer_grow_a_b_1ltr_2.jpg?v=1769190292","url":"https:\/\/growershouse.co.uk\/products\/advanced-nutrients-connoisseur-grow-ab","provider":"Growers House ","version":"1.0","type":"link"}
