Hesi OrchiVit 1l
Hesi OrchiVit 1 litre is a complete fertiliser and biostimulant engineered specifically for orchids and epiphytic plants. The formula combines the NPK nutrition of Hesi TNT Complex with the vitamins of Root Complex and the amino acid profile of SuperVit — three products concentrated in a single bottle. OrchiVit delivers 100% organic nitrogen via salt-free urea, making it exceptionally gentle on sensitive orchid root systems. With an NPK ratio of 4-2-3 plus trace elements, vitamins A through E, B-complex and amino acids, this formulation addresses the complete nutritional profile of orchids. Dose 1-2 ml per litre for slow-growing species, 3-5 ml for fast growers. Order from plantandflower.be for fast delivery in Belgium.
Hesi OrchiVit 1 litre – Complete orchid nutrition with vitamins and amino acids
Hesi OrchiVit goes beyond conventional orchid fertilisers. It combines three proven Hesi formulations — TNT Complex, Root Complex and SuperVit — into a single concentrate optimised for orchids and epiphytic plants. The results are measurable within weeks: improved leaf turgor, enhanced root development and more prolific flowering.
Understanding orchid nutritional requirements
In their natural habitat, orchids are epiphytes that grow in forest canopies without any terrestrial substrate. They depend entirely on airborne nutrients — pollen, decomposing organic matter, even dead insects carried by wind. Wild orchids form mycorrhizal symbioses with root fungi that convert organic material into plant-available nutrients. In indoor cultivation, these fungal partnerships rarely establish successfully, creating a nutritional gap that OrchiVit's vitamin-rich formula effectively bridges.
The most common indoor orchid, the Phalaenopsis, is particularly sensitive to salt accumulation around its aerial roots. Conventional mineral fertilisers leave salt residues in the substrate that can damage the velamen — the spongy outer layer of orchid roots responsible for moisture absorption. OrchiVit solves this with 100% organic urea nitrogen that is absorbed without leaving ionic residue, preserving root integrity and function over extended growing periods.
Three Hesi products in one bottle
- TNT Complex: delivers NPK base nutrition (4-2-3) using salt-free organic urea nitrogen that supports healthy vegetative growth without osmotic stress on sensitive root tissue.
- Root Complex: promotes root development and supports beneficial microflora in the rhizosphere, critical for orchids grown in bark-based substrates with limited microbial diversity.
- SuperVit: supplies vitamins A, B1, B2, B3, B6, B12, E and folic acid, plus essential amino acids that enhance metabolic efficiency and photosynthetic output.
The role of vitamins in orchid physiology
Vitamins are an underappreciated factor in orchid nutrition. Thiamine (B1) is directly involved in root development and stress recovery — particularly relevant after repotting, which orchids notoriously dislike. Vitamin B12 and folic acid participate in cell division processes required for new leaf and root formation. By supplying these cofactors directly through OrchiVit, orchids can redirect the metabolic energy normally spent on vitamin biosynthesis toward growth and flowering instead.
Dosage and application
Add OrchiVit to irrigation water up to 4 times per month. Do not fertilise during the dormancy period — typically after flowering, when no active growth is visible. Dosage depends on growth rate: 1-2 ml per litre for slow-growing species like Phalaenopsis, 3-5 ml per litre for vigorous epiphytes. For foliar application, 1 ml per litre is sufficient.
The organic nitrogen in OrchiVit is not detected by EC meters. Always base dosage on the recommended millilitres per litre, not on conductivity readings. This is a key distinction from mineral feeds in the Hesi Pro-Line range such as Hesi TNT where EC measurement is reliable.

Is Hesi OrchiVit suitable for all orchid species?
Yes, OrchiVit is formulated for all orchid species including Phalaenopsis, Cymbidium, Dendrobium and Oncidium. Adjust dosage based on growth rate: 1-2 ml/L for slow growers, 3-5 ml/L for vigorous species.
Can OrchiVit be used for other houseplants?
Absolutely. OrchiVit is a mild, vitamin-enriched formula that benefits all houseplants and epiphytes including bromeliads, tillandsias and ferns. The salt-free nitrogen and vitamin complex provide a gentle nutritional boost for any salt-sensitive plant.
Why does EC measurement not work with OrchiVit?
OrchiVit contains 100% organic nitrogen as urea. Urea is a non-ionic molecule that EC meters cannot detect. Always dose based on the recommended millilitres per litre rather than conductivity values.
Should I fertilise orchids during their rest period?
No. Suspend all fertilisation during dormancy, typically after flowers have dropped. Resume OrchiVit application when you observe new root tips or leaf growth emerging, signalling the start of a new active growth cycle.
