HESI Coco

Coco feed
For coco-based routines
pH/EC check needed

A coco-specific fertilizer for houseplants grown in buffered coco or coco-heavy mixes. HESI Coco includes calcium, magnesium and trace elements to suit the way coco holds nutrients, so it makes more sense than general plant food for plants that live mainly in coir.

HESI Coco is for houseplants rooted in coco, where nutrition has to come through the watering solution. It is not the HESI bottle to pick for standard potting soil.

For coco-led foliage care

It suits aroids and other foliage plants rooted in coco-based media where nutrition and mineral balance must be supplied through the watering plan. This is a targeted option, not a general shelf feed.

Pick by substrate first

If coco is the main medium, HESI Coco keeps the plan clearer. If the plant sits in normal potting mix, TNT Complex or HousePlant Elixir will usually make more sense.

What's inside:

NPK Ratio: NPK 3-4-5 + Ca/Mg, trace elements, vitamins and amino acids
Nutrient basis: Mineral

HESI Coco is a mineral base feed for coco-grown plants. Coco does not behave like ordinary soil, so this product sits in the coco nutrient lane.

The formula is NPK 3-4-5 with calcium, magnesium, trace elements, vitamins and amino acids. Use it where coco is the main medium and water management is part of the routine.

How to use it

Mix HESI Coco 50 ml into 10 L of water and adjust the finished solution to about pH 5.8-6.2. Use with every watering on coco only when plants are actively growing and the pot drains well.

Check EC when feeding prized or salt-sensitive plants in small containers.

➜ A few notes before measuring, mixing or applying :

Let excess solution drain away; stagnant coco pots create root problems quickly. Watch for salt build-up and rinse with adjusted water when needed.

Treat coco as a frequent-feed medium with good drainage, not as rich soil.

Frequently Asked Questions about HESI Coco

Is HESI Coco only for coco substrates?

Yes. It is built for coco-grown plants and coco-heavy chunky mixes. Coco needs regular mineral feeding, so this formula is made for that kind of setup.

Can I use HESI Coco for aroids?

Yes, if the aroids are growing in coco or a coco-heavy mix with good drainage. For peat-based soil mixes or delicate root systems, choose a gentler houseplant feed.

How do I apply HESI Coco correctly?

Mix 50 ml into 10 L of water and adjust the finished solution to about pH 5.8-6.2. Let excess solution drain away and watch for salt build-up in small pots.

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 :)
