HESI Hesilicio adds silicon support to a feeding plan that already has nutrition covered. It is for growers who want firmer, more resilient growth without changing the base feed.

For firmer managed growth

It fits foliage plants, stressed plants and advanced setups where stronger stems, leaves and general tolerance matter. The basics still come first: light, water, roots and the right base feed.

Add silicon after the base feed

Hesilicio sits beside products such as SuperVit and PowerZyme. Start with a suitable fertilizer, then add silicon when the growing conditions call for extra support.

HESI Hesilicio suits stronger foliage plants, semi-hydro collections and plants facing heat, dry air or handling stress. It works with soil, coco and hydro feeding once the main fertilizer is already chosen.

Skip it for low-demand plants in stable household conditions unless you have a clear reason to add silicon.

What's inside:

NPK Ratio: No NPK / 3% orthosilicic acid colloidal
Nutrient basis: Silicon additive

HESI Hesilicio is a silicon additive for managed feeding plans. It is not plant food on its own, even though it belongs beside nutrition products.

The composition is no NPK with 3% colloidal orthosilicic acid. Use it as silicon support, not as a reason to increase or replace the base fertilizer.

How to use it

Dilute HESI Hesilicio at 0.5 ml/L once per week; stay within the recommended dose. Add it to water before other nutrients if your feeding order requires pH or compatibility control.

Use during active growth when plants are building new leaves, stems and roots.

➜ A few notes before measuring, mixing or applying :

Measure accurately; silicon additives can affect solution balance when overused. Keep an eye on pH after mixing, especially in hydro or semi-hydro.

Store away from heat and rinse equipment after use.

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 :)
