Hesi Pro-Line TNT 1l
Hesi Pro-Line TNT Complex is an NPK 3-2-3 growth fertiliser for the vegetative phase on soil and coco substrates. Its nitrogen source is predominantly organic, delivering a low EC reading with high actual nutritional value. This low-salt approach protects young root systems and makes TNT ideal for long-term use on mother plants. Enriched with vitamins and plant-active sugars that enhance photosynthesis and metabolism, TNT drives the development of multiple growth points for a strong branching structure. Application rate is 50 ml per 10 litres of irrigation water. Order at plantandflower.be for fast shipping across Belgium.
Hesi Pro-Line TNT 1l – Organic Nitrogen NPK Growth Fertiliser for Soil and Coco
Vegetative phase performance directly determines flowering potential. Hesi Pro-Line TNT Complex delivers an NPK 3-2-3 profile engineered for strong, balanced growth on soil and coco substrates. The predominantly organic nitrogen source sets TNT apart from conventional mineral growth fertilisers by maintaining high nutrient delivery at significantly lower EC values.
Organic nitrogen: high efficacy at low salinity
Standard mineral nitrogen fertilisers rely on ionic salt compounds that directly increase electrical conductivity. TNT Complex uses 100% organic nitrogen compounds that do not dissociate into ions in solution. EC meters cannot detect these molecules, resulting in a deceptively low conductivity reading despite substantial nitrogen content. The practical benefit is significant: young plants and sensitive root systems receive full nitrogen nutrition without the osmotic stress caused by high salt concentrations.
- NPK 3-2-3 with all macro and trace elements: complete nutrition profile requiring no additional supplements during the vegetative phase.
- Low salt load for mother plants: prevents substrate salinity build-up in containers used for extended cultivation periods.
- Vitamins and plant-active sugars: enhance chlorophyll production and metabolic throughput for accelerated biomass development.
Application protocol and dosage management
Apply 50 ml per 10 litres of irrigation water from the moment cotyledons have dried and the plant begins active nutrient uptake from the substrate. Seeds contain sufficient nutrients to sustain the seedling through its initial embryonic phase – fertilisation before this point is unnecessary. For mother plants, maintain 20 ml per 10 litres to prevent excessive vegetative growth that would redirect energy away from productive flowering sites. One litre of TNT produces a minimum of 250 litres of nutrient solution. Combine with Hesi Bloom Complex during the transition week using a 50/50 ratio before switching fully to bloom nutrition.
Growth point multiplication and structural development
Plants fed with TNT Complex consistently develop a higher number of lateral branches and active growth points compared to basic mineral feeds. This dense branching architecture creates more potential flowering sites, directly translating to increased yield capacity. The characteristic deep green colouration indicates optimised chlorophyll density and photosynthetic efficiency. The added vital substances go beyond nutrition – they improve the plant's own capacity to absorb and utilise available nutrients through enhanced metabolic pathways.
Positioning within the Hesi feed schedule
TNT carries the green colour code in the Hesi system, designating soil-optimised products. When plants signal the onset of flowering, introduce Hesi Boost to activate the blooming response while transitioning from TNT to the appropriate bloom fertiliser. For growers seeking additional plant vitality throughout the cycle, Hesi Super Vit provides concentrated bio-stimulant support that complements TNT's nutritional profile during the vegetative phase.

What is the correct dosage for Hesi TNT Complex?
Apply 50 ml of Hesi TNT Complex per 10 litres of water during the growth phase. For mother plants and very young seedlings, use half dosage at 20 ml per 10 litres. Do not exceed the recommended rate as excessive nitrogen promotes disproportionate vegetative growth that can reduce flowering efficiency later in the cycle.
Why does Hesi TNT show a low EC value on my meter?
EC meters measure ionic conductivity in solution. The organic nitrogen in TNT Complex exists as non-ionic compounds that are invisible to conductivity measurement. The actual nutritional value is substantially higher than the EC reading suggests. This is a deliberate design feature that keeps salt stress low while maintaining full nitrogen delivery to the plant.
Can Hesi TNT be used on coco substrate?
TNT Complex is designed for both soil and coco during the vegetative phase at the same 50 ml per 10 litres dosage. When transitioning to flowering on coco, replace TNT with Hesi Coco as the base nutrient and supplement with Hesi PK 13/14 to meet the increased phosphorus and potassium demand of the reproductive phase.
When should I switch from Hesi TNT to bloom fertiliser?
Transition from TNT to bloom fertiliser when plants show the first signs of flowering or when you adjust the light cycle to 12/12. During the first transition week, blend TNT and Bloom Complex at a 50/50 ratio to ensure a gradual nutritional shift, then switch fully to the bloom fertiliser for the remainder of the flowering phase.
