Universal Substrate Set – flexible ingredients for everyday repotting

Universal Substrate Set is a practical kit for building a better everyday houseplant mix. It is aimed at typical indoor plants that do not need a specialist carnivorous, orchid or cactus substrate.

The advantage is control: you can keep the base comfortable for roots while tuning structure for drainage and longevity.

Practical use

Start with the soil base, then add structure materials gradually until the texture matches the plant and pot size.
Mix through the full pot volume so water and air move evenly through the root zone.
Small plugs and fine roots usually need less chunky material than large, established plants.

Extra notes

If a plant needs a truly specialist setup (very mineral succulents, orchids, terrariums, semi-hydro), use a dedicated mix rather than forcing a universal blend to do everything.

Best use cases

This set is meant to make mixing easier. Use it as a full recipe or as a starting point you can adjust with extra mineral or organic components.

If you repot multiple plants, mix small batches first so you can tune the texture and drying rate to each pot and root system.

Before you order

Pre-moisten dry components for a more even blend.
Keep leftovers sealed and dry between uses.
Match chunk size to pot size: smaller pots need finer structure.

For an everyday indoor blend, measure by volume and use this as a flexible starting mix for plants that do not need a specialist substrate.

Start with: 5 parts Universal Soil, 2 parts perlite, 2 parts pine bark and 1 part Lava Rock Granules.
For steadier moisture: Use a little more Universal Soil and less bark for fine roots, small pots or plants that dry too quickly.
For more structure: Increase pine bark or Lava Rock Granules slightly for larger plants, deeper pots or homes where soil stays wet for too long.

This is a practical middle ground between plain potting soil and highly specific mixes. Use dedicated substrates for carnivorous plants, Lithops, orchids, closed terrariums or reservoir-based semi-hydro setups.

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 :)
