Description

A two-part vegetative base that holds its own pH

Sensi Grow A&B is the vegetative half of Advanced Nutrients' two-part base programme, built on their pH Perfect technology. The feed carries buffering agents that pull the solution into the 5.5 to 6.3 band and hold it there, which removes the single most common cause of a failed grow.

Key Benefits

  • pH Perfect buffering - the solution self-corrects into range and stays there between feeds
  • Two parts, full control - adjust the ratio as the plant moves through vegetative growth
  • Chelated micronutrients - available across the whole working pH band, not just at one point
  • Suits every medium - hydroponics, coco and soil at a reduced rate
  • Pairs with Sensi Bloom A&B - the same programme carried through to flower

pH drift between feeds

A reservoir left for a week climbs or falls, and by the time you notice the plant has spent days unable to take up iron or calcium. The symptoms look like a deficiency and get treated by feeding harder, which makes it worse. A buffered base removes the drift rather than asking you to chase it.

How to Use

  • Mixing order: Part A first into plain water, stir thoroughly, then Part B - never combine the concentrates
  • Early vegetative: 2 ml per litre of each part
  • Late vegetative: 4 ml per litre of each part
  • pH: leave it alone - the feed corrects itself. Only intervene if it sits outside 5.5 to 6.3 after an hour
  • Transition: swap to Sensi Bloom A&B as the lights change

Technical Specifications

  • Programme: Advanced Nutrients pH Perfect Sensi two-part base
  • Role: Vegetative
  • Typical dose: 2 to 4 ml per litre of each part
  • pH: Self-buffering to 5.5 - 6.3
