Description

Strips the residue out before harvest rather than diluting it

Flawless Finish is a pre-harvest flush that actively binds and removes accumulated mineral salts from the medium and the plant, rather than simply diluting the reservoir with plain water.

Key Benefits

  • Chelates and removes salts - plain water dilutes; a flush agent binds and carries out
  • Cleaner burn and taste - residual nitrogen and salts are what make a crop harsh
  • Works in every medium - hydroponics, coco and soil
  • Short and simple - one week at the end of the cycle
  • Any programme - not restricted to Advanced Nutrients

A harsh crop that was grown well

Nutrients left in the plant and the medium at harvest carry through to the finished product as harshness and a chemical taste. It is the commonest way a technically good grow disappoints, and it happens in the final week - the one part of the cycle most people rush.

How to Use

  • Final week: replace the feed with 2 ml per litre in plain water
  • Hydroponics: run for the last 5 to 7 days, changing the reservoir once
  • Soil and coco: water to run-off twice over the final week
  • Do not combine: stop all base feed and additives while flushing
  • Signs it is working: fan leaves fading and yellowing is expected and correct
