Description

Brings out the colour a variety is already capable of

Purpinator supports anthocyanin production - the pigments responsible for purple and red colouring in flowers and leaves. It cannot invent colour a variety does not carry, but where the genetics are there it lets them show without the cold night temperatures usually needed to trigger them.

Key Benefits

  • Colour without cold nights - dropping night temperature to force colour costs growth - this does not
  • Supports the plant's own pigments - anthocyanins are made by the plant, not added by the product
  • Late flower window - dosed through the weeks when colour actually develops
  • Low EC contribution - fits inside an existing feed schedule
  • Works with any base feed - mineral or organic

Chasing colour by chilling the room

The traditional way to bring out purple is a large day-to-night temperature drop, which slows metabolism and costs yield in the final weeks - the most expensive weeks to lose. Supporting anthocyanin production directly gets the colour without the trade.

How to Use

  • Weeks 4 to 7 of flower: 2 ml per litre at every feed
  • Expectations: varieties without the genetics will not colour, whatever you feed them
  • Taper: continue to the final flush
  • EC: reduce the base feed slightly to hold total EC
  • Media: soil, coco and hydroponics
