HESI Bio Grow is the plant-origin growth feed in the HESI range. It suits growers who want an organic-style base fertilizer for active foliage growth.

For organic-minded growers

It suits growers looking for a vegan, plant-based feed. It works best when the substrate and watering habits also support organic care.

Where mineral feeds fit better

For long-standing reservoirs or inert-media setups, choose a hydro or coco nutrient with faster mineral availability and more precise water control.

HESI Bio Grow is made for soil-grown houseplants and organic care where microbial activity matters. It works best in living or lightly fertilized potting mixes; sterile hydro reservoirs need a mineral hydro feed.

Use it for leafy plants that need an organic growth feed within a compact organic routine.

What's inside:

NPK Ratio: NPK 4-1-4; liquid biological NPK fertiliser of plant origin
Nutrient basis: Organic/biological plant-origin NPK fertiliser

HESI Bio Grow is a plant-origin biological NPK fertilizer for active growth. It sits in the organic-style base-feed category, not the additive shelf.

The formula is NPK 4-1-4. Let it carry the growth-feed role, then measure any extras around that base.

How to use it

Use HESI Bio Grow 5 ml/L for the standard growth dose, with a lighter mix for slow indoor conditions. Apply through the watering can on plants that are actively using water and nutrients.

Start lighter after repotting or when switching from a mineral feed.

➜ A few notes before measuring, mixing or applying :

Organic feeds can change smell or reservoir cleanliness if used in standing water. Use only one full-strength growth feed at a time.

Shake well before measuring and wipe spills from caps or shelves.

Frequently Asked Questions about HESI Bio Grow

Is HESI Bio Grow a complete fertilizer?

Yes. It is an organic base fertilizer with NPK 4-1-4, made for growth feeding rather than rooting or pH correction.

What substrates suit HESI Bio Grow?

It suits soil-grown houseplants and living or lightly fertilized potting mixes. It is not the right product for sterile hydro reservoirs or standing water systems.

Can I combine HESI Bio Grow with other fertilizers?

Avoid combining it full-strength with another growth fertilizer. If you use several products in the same week, reduce the total strength so the plant is not double-fed.

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 :)
