Description

The flowering half of the Hesi organic programme

Hesi Bio Bloom is the organic flowering feed for soil and living soil, weighted to organic phosphorus and potassium for the weeks when flowers are filling.

Key Benefits

  • Organic through flower - most growers go organic in veg and give up at the flip
  • Supports aroma - organic programmes are chosen for flavour as much as weight
  • Gentle on the root zone - far less salt build-up than a mineral bloom feed
  • Pairs with Bio Grow - one organic line through the cycle
  • Works with a PK - add PK 13/14 in the bulking weeks if needed

Organic phosphorus arriving too late to matter

Organic phosphorus releases slowly, and in a short flowering cycle it can become available after the weeks that decide density. That is the yield penalty organic growers accept. Feeding early and consistently, at a proper rate, closes most of it.

How to Use

  • Transition: 2 ml per litre as the lights change
  • Mid flower: 4 ml per litre at every watering
  • Late flower: hold the rate, then plain water for the final week
  • Reservoir: mix fresh and keep it moving
  • Target pH: 6.0 to 6.5
