Semi-Hydro Mix – inert substrate for reservoir-based growing

Semi-Hydro Mix gives roots a mineral framework with air pockets and access to a controlled reservoir. It is a system choice, not just a different bag of soil.

More to know

Inert mineral base: does not behave like soil
Reservoir use: works with suitable semi-hydro containers
No built-in feed: requires a measured nutrient routine
Reusable structure: can be cleaned and reused where appropriate

How to get started

Because the medium is inert, nutrients must come from the solution. Use a fertiliser suited to the setup and keep strength appropriate for the plant and stage of adaptation.

Transition notes

Some plants adapt easily; others stall or lose old roots during transition. Start with healthy plants and monitor roots closely during the first weeks.

Key points

This mix is built around structure first. Use it as a complete potting mix, or blend it into a base soil to adjust airflow and drying speed.

Watering should match the pot size and root mass. Check moisture at depth and adjust your routine after the first few cycles.

Mixing guide

Moisten dry components before potting so the mix settles evenly.
Choose pot size for the root ball, not for the top growth.
Top-dress with the same mix to reduce surface compaction.

Semi-Hydro Mix FAQs

Is Semi-Hydro Mix the same as potting soil?

No. Semi-Hydro Mix is for mineral or semi-hydroponic growing, where roots grow in an inert medium and receive nutrients through the water.

Does Semi-Hydro Mix contain plant food?

No. Mineral semi-hydro substrates provide structure, air space and water movement, but plants still need a suitable nutrient solution.

Can I move any plant straight from soil into Semi-Hydro Mix?

Some plants adapt well and others do not. Remove old soil carefully, expect an adjustment period, and avoid converting weak or stressed plants.

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 :)
