Mineral Root Additive for Hydroponic Growing

Plagron Hydro Roots is a mineral root additive developed for hydroponic systems. Its phosphorus and boron content supports root development and helps plants take up water and nutrients during early growth.

The mineral formulation contains no organic ingredients, making it suitable for use in hydroponic nutrient solutions and irrigation systems. Hydro Roots can be used alongside a suitable base nutrient, including Plagron Hydro A&B.

Build a Stronger Root System from the Start

Give your hydroponic plants the foundation they need with Plagron Hydro Roots, a concentrated mineral root enhancer developed specifically for hydro and system-fed growing.

Its combination of phosphorus and boron supports fast root development, increased root branching and thicker root hairs, helping create a larger root surface area for efficient water and nutrient uptake. A stronger, better-developed root structure gives plants the support they need for vigorous growth as they move through the growing cycle.

With no organic ingredients, Hydro Roots is ideal for hydroponic and irrigation systems where a clean nutrient solution matters, helping minimise the risk of clogged drippers and pumps.

Frequently Asked Questions

Hydro Roots is a mineral root enhancer designed to promote the development of a strong, well-branched root system. It supports secondary root development and thicker root hairs, increasing the root surface available for absorbing water and nutrients.

Yes. Hydro Roots was specifically developed for hydroponic growing and system feeding. Its mineral formulation contains no organic ingredients, making it suitable for circulated irrigation systems, drippers and pumps.

Shake well before use and add 1 ml of Hydro Roots per litre of water, giving a dilution of 1:1,000. Plagron recommends using the solution with each watering during the recommended application period.

Hydro Roots is a strictly mineral product developed with system feeding in mind, whereas Power Roots contains organic components and is better suited to hand feeding. If you're running a recirculating hydroponic or irrigation system, Hydro Roots is the better choice for reducing potential clogging issues.

For short-cycle plants, use Hydro Roots through the early growing period and stop after the third week of flowering. By this stage, the aim is to have an established root system so the plant can direct more of its energy towards flower development.

Yes. Plagron specifically recommends combining Hydro Roots with Hydro A & B, Green Sensation and Power Buds. It can also be combined with products from Plagron's Universal range, allowing you to build a feeding programme around your particular setup.
