Plagron Hydro Roots is a technical root additive for hydro-style systems. Use it in short windows around root establishment rather than as a permanent background feed.

Roots in hydro systems

It fits young plants or hydro-grown houseplants that need root support while the reservoir still carries the main nutrition. Inert substrates are the natural match.

Beside Hydro A+B

Hydro A+B is the base feed; Hydro Roots is specialist support around root development. Treating the root additive as a complete fertilizer would blur the job it was made to do.

Plagron Hydro Roots is made for hydroponic and semi-hydro systems where mineral additives are preferred. It fits LECA, clay pebbles and inert media that rely completely on solution feeding.

What's inside:

NPK Ratio: NPK 0-20-0 + 0.023% boron; mineral phosphorus/boron root additive
Nutrient basis: Mineral phosphorus/boron root additive

Plagron Hydro Roots is a phosphorus-and-boron root additive for hydro systems. It is more technical than a general root stimulator because it changes the nutrient solution.

The formula is NPK 0-20-0 with 0.023% boron. Use it in the intended rooting window and check the rest of the nutrient mix before adding more phosphorus.

How to use it

Use Plagron Hydro Roots 1 ml/L in the nutrient solution during the root-development phase. Mix into fresh hydro water before final pH/EC adjustment.

Apply while roots are establishing, then simplify the feed once the plant is stable.

➜ A few notes before measuring, mixing or applying :

Because phosphorus is high, use it only during the intended rooting window. Check the full nutrient mix before adding other phosphorus-heavy products.

Monitor pH/EC so the root additive does not push the nutrient solution out of range.

Frequently Asked Questions about Plagron Hydro Roots

What is Plagron Hydro Roots for?

It is a hydro root additive for the root-development phase in hydroponic and semi-hydro systems. It suits LECA, clay pebbles and other inert media.

Is Plagron Hydro Roots a complete fertilizer?

No. It is not a balanced base feed and should be used beside Hydro A+B or another hydro fertilizer.

Why should Plagron Hydro Roots be used only during rooting?

It has a high phosphorus profile, so it belongs in the intended rooting window. Keep an eye on the full nutrient mix so phosphorus does not stack too high.

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 :)
