The top of the Advanced Nutrients base range
Connoisseur Grow A&B is Advanced Nutrients' professional-grade vegetative base, aimed at growers running at the limit of what their room can support. It carries a wider amino acid and micronutrient package than Sensi alongside the same pH Perfect buffering.
Key Benefits
- Built for high-intensity rooms - designed for crops pushed hard on light and CO2
- Amino acids and vitamins included - the plant spends less energy building its own
- pH Perfect buffering - holds 5.5 to 6.3 without intervention
- Full ratio control - two parts, adjusted through vegetative growth
- Pairs with Connoisseur Bloom A&B - the same grade carried into flower
A base feed that runs out of headroom
Under high light and enriched CO2 a plant can outgrow what a standard base can supply, and the ceiling shows up as growth that plateaus while everything else in the room says it should not. A richer base raises that ceiling - though it is wasted money in a room that is not pushing it.
How to Use
- Mixing order: Part A first, stir, then Part B
- Early vegetative: 2 ml per litre of each part
- Late vegetative: 4 ml per litre of each part
- EC: watch it closely - this is a rich feed and it is easy to overshoot
- pH: self-correcting to 5.5 - 6.3
