HESI TNT Complex

Everyday plant food
Use as the main feed
Dose carefully

Use HESI TNT Complex for leafy houseplants potted in soil, coco or mixed media that are pushing new growth and need more than a gentle maintenance feed. It suits fast-growing foliage plants, young plants and recently rooted cuttings when used at a lighter dose. A good fit for mineral nutrition with a predictable response.

Tracked shipping

HESI TNT Complex is for active foliage growth in soil or coco-style care, especially when a gentle maintenance feed is no longer enough. It suits plants that are clearly building leaves, roots and stems.

For hungry foliage

A strong match for aroids, vines, palms and young plants in soil or coco when general houseplant food feels too soft. It gives a growth-focused feeding lane while keeping the setup outside hydro-style management.

Place in the HESI range

HousePlant Elixir is the gentler everyday option. TNT Complex is the stronger growth feed for established leafy plants that can use more mineral nutrition.

HESI TNT Complex is made for plants growing in soil or coco, especially leafy houseplants that need more than a gentle maintenance feed. It fits aroids, ficus, palms and other foliage plants once they are established and actively growing.

Choose a hydro nutrient instead for plants kept in water reservoirs or fully inert LECA systems.

What's inside:

NPK Ratio: NPK 3-2-3 + secondary nutrients and chelated trace elements
Nutrient basis: Organo-mineral

HESI TNT Complex is an organo-mineral growth feed for leafy plants in active growth. It is stronger and more directed than a simple maintenance plant food.

Its formula is NPK 3-2-3 with secondary nutrients and chelated trace elements. Use the composition as the base feed, then add supplements only for a specific reason.

How to use it

Use HESI TNT Complex as follows: measure 50 ml into 10 L for the standard dose; halve it for young plants, cuttings or very frequent use. Apply during active growth when foliage plants are producing new leaves, stems or roots.

Small pots, low light and winter conditions call for a lighter dose than the bottle maximum.

➜ A few notes before measuring, mixing or applying :

When growth slows, reduce feeding before leaf tips show stress. Compact pots and lower-light shelves need a softer approach than large, actively growing plants.

Do not run another complete fertilizer at full strength in the same week. If salts appear on the pot surface or leaf edges brown after feeding, water through lightly and restart at a lower strength.

Shake before measuring and close the bottle after use so the concentrate stays even.

Frequently Asked Questions about HESI TNT Complex

Can I use HESI TNT Complex for aroids?

Yes, but mainly for established aroids in soil or coco that are actively growing and not root-stressed. Because TNT Complex contains urea-based nitrogen, it is not the gentlest first choice for sensitive Anthurium, Alocasia, fresh imports, small cuttings or plants in semi-hydro.

Is HESI TNT Complex a complete fertilizer?

Yes. It is a base fertilizer with NPK 3-2-3 plus secondary nutrients and chelated trace elements, so it can stand alone for normal soil or coco feeding.

How should I dose HESI TNT Complex for houseplants?

Use 50 ml per 10 L of water as the standard dose, but start at half strength for indoor plants, young plants, cuttings, small pots or frequent feeding. Do not combine it full-strength with another complete fertilizer in the same week.

Die Pflanzen waren prima verpackt und ein heatpack war im Paket enthalten. Die Lieferzeit hat 2 bis 3 Tagen gedauert, was aus meiner Sicht wirklich gut ist. Alle drei Pflanzen haben die Lieferung gut überstanden. Ich habe mich auf Hoyas spezialisiert und habe schon die nächsten Pflanzen meiner Wunschliste auf der Website gefunden. Daher wird die nächste Bestellung nicht lange auf sich warten lassen.

The plants are carefully packaged and arrive in great conditions (I’m based in Spain) and they’re always there to help in any way they can with your purchase.I have and will always recommend Foliage Factory to every friend I can. I’m not only satisfied with their plants and prices, but their customer service is exceptional.

Very healthy and well packed plant. Unfortunately there was one plant that ordered couldn’t be delivered as it was out of stock hence 1 star less.

Die Sendung kam leider in keinem guten Zustand bei mir an, kann passieren. Habe mich darauf hin sofort an Foliage Factory gewandt und habe selten einen so guten, schnellen, freundlichen und kulanten Kundendienst erlebt.

Everything arrived in good condition and very well packed - it wasn't easy with a fragile plant and a heavy bag of substrate. I recommend it!

Bester online-Pflanzenhandel den ich kenne (habe davor 4 andere ausprobiert). Eine teure Pflanze wurde beim Transport beschädigt und mir ersetzt. Der Kontakt dabei war auch sehr nett (danke Jan) und hat mir gut geholfen. Die anderen Pflanzen sind in einem sehr guten Zustand, keine Schädlinge, super Bewurzelung. Nur zu empfehlen! :)

The plants have arrived in perfect condition, the roots and the foliage so so healthy! I had problem with 1 plant out of 16 and they have responded to my email almost instantly and the issue was resolved straight away. I'm really impressed and satisfied, definitely getting more plants from them again!

I received perfectly heathy and absolutely beautiful plants, even bigger than expected. The delivery within Europe was really fast. I think Foliage Factory has one of the best plant web shops in the internet. It‘s just great to get so much informations about the plants. I will definitely order again :)
