Description

The vegetative base the whole Hesi soil programme is built on

Hesi TNT Complex is the vegetative base feed for soil. TNT stands for Total Nitrogen Technology - the nitrogen is supplied in several forms that become available at different rates, so the plant gets a steady supply rather than a spike followed by a shortage.

Key Benefits

  • Nitrogen in several forms - steady availability instead of a surge and a crash
  • Formulated for soil - accounts for the reserve and buffering the medium already provides
  • Includes vitamins and amino acids - Hesi build these into the base rather than selling them separately
  • Low salt index - gentler on soil biology than a hydroponic feed poured onto soil
  • Pairs with Bloom Complex - the same programme carried into flower

Soft, stretchy growth from too much fast nitrogen

A feed that delivers all its nitrogen at once produces tall, soft growth that cannot carry a canopy and attracts every sap-feeding pest in the room. Staged nitrogen paces growth instead, which gives shorter internodes and a sturdier plant going into flower.

How to Use

  • Seedlings: 2.5 ml per litre once the first true leaves are open - half the full rate
  • Vegetative growth: 5 ml per litre at every watering
  • Transition: reduce as Bloom Complex comes in over the first fortnight of flower
  • Watering: Hesi feeds are designed to be used at every watering rather than alternated
  • Target pH: 6.0 to 6.5

Technical Specifications

  • Programme: Hesi soil
  • Role: Vegetative base nutrient
  • Medium: Soil and soil mixes
  • Typical dose: 5 ml per litre, half that for very young seedlings
  • Target pH: 6.0 to 6.5
  • Partner product: Hesi Bloom Complex
Feed Chart
Hesi TNT Complex · soil and coco-based substrates
Stage Per 1 L Per 10 L
Growth / vegetative, soil and coco 5 ml 50 ml
Very young seedlings and cuttings, or continuous long-term feeding 2.5 ml 25 ml
Note — Hesi publish this as 50 ml per 10 litres, halved for very young seedlings or cuttings and for continuous long-term feeding. Mix into the irrigation water. Most of the nitrogen is organic so the EC stays low, which makes it safe for long-term use on mother plants. Do not start feeding until the cotyledons have dried and shrivelled. Check pH and EC after mixing.
