Description

The flowering half of the Hesi hydroponic programme

Hesi Hydro Bloom is the flowering base for hydroponics, clay pebbles and rockwool. It carries the phosphorus and potassium weighting for flower alongside the vitamins and amino acids Hesi include as standard.

Key Benefits

  • Complete base - vitamins and amino acids included
  • Stable in a recirculating tank - fewer pH corrections across a week
  • Clean in drippers - no organic load to foul irrigation
  • Pairs with Hydro Grow - one programme, one water type

A hydroponic reservoir that drifts all week

In an inert medium there is no buffer at all, so a feed that is not stable in solution takes the reservoir with it. pH swings mean the plant spends part of every week unable to take up iron or calcium, which reads as a deficiency and gets fed rather than fixed.

How to Use

  • Transition: 3 ml per litre
  • Mid flower: 5 ml per litre
  • Late flower: hold, then switch to plain water over the final week
  • Target pH: 5.5 to 6.2

Technical Specifications

  • Programme: Hesi hydroponic
  • Role: Flowering base
  • Typical dose: 3 to 5 ml per litre
