Plagron Hydro Roots 0.1l
The Plagron Hydro Roots 0.1L is the trial format of the fully mineral root stimulator from Plagron, specifically engineered for hydroponic cultivation systems. Contains NPK 0-20-0 with 20.47% phosphorus and 0.23% boron — two minerals promoting root initiation, secondary branching, and root-hair thickening. Its strictly mineral composition prevents clogging issues in drip irrigation and hydroponic systems, unlike organic alternatives that cause filter blockage. Dosage 1 ml per litre (1:1000) at every watering, up to and including the third flowering week. The trial bottle yields approximately 100 litres of nutrient solution — enough for one complete short cycle. Compatible with Hydro A+B base nutrients.
Plagron Hydro Roots 0.1L — Mineral Root Stimulator for Hydroponic Systems
The Plagron Hydro Roots 0.1L is the most compact and accessible format of Plagron's specialist root stimulator engineered for hydroponic cultivation. Its distinguishing feature: this product is 100% mineral with zero organic components — precisely what a hydroponic system requires to operate stably without filter clogging or algal bloom. A foundational product from the Plagron range for European hydroponic growers building their nutrient programme on solid foundations from day one.
The Science of Stronger Root Systems
Hydro Roots operates via two targeted minerals: phosphorus (20.47%) and boron (0.23%). Phosphorus is one of the three primary nutrients (the "P" in NPK) specifically responsible for root development and cell division in growth-point meristems. Boron is an essential micronutrient reinforcing cell walls and improving membrane stability within root hairs. Combined, these minerals deliver three measurable effects: accelerated root initiation in young plants or post-transplant, increased secondary branching throughout the root system, and thickened root hairs with enhanced absorption capacity. Outcome: a root architecture absorbing more nutrients and water per plant-hour, translating directly into faster above-ground growth and healthier overall development.
- NPK 0-20-0: pure phosphorus for targeted root development without excess foliage growth.
- Boron 0.23%: reinforces root-hair cell walls for improved mechanical resilience.
- 100% mineral: no organic matter — safe for drip systems and hydroponic pumps.
- Dosage 1:1000 (1 ml/L): at every watering up to and including week 3 of flowering.
- Extended stability: mineral composition stays stable in reservoirs longer than organic alternatives.
Hydro Roots vs Power Roots: Making the Right Choice
Plagron offers two root stimulators that appear similar but are fundamentally different. Power Roots contains organic components (favourable for hand-watering in soil or coco), while Hydro Roots is purely mineral (essential for automated hydroponic systems). Running drip irrigation, DWC, NFT, or other closed hydroponic installation? Hydro Roots is the correct choice — organic materials cause filter clogging, algal growth, and bacterial proliferation in the nutrient reservoir. For growers preferring an organic approach, the Power Roots 0.1L offers the alternative in matching format. After a successful first cycle, you can upgrade to the 1L volume for continuous operations without replenishment concerns.
Pairing with Base Nutrients and Additives
For optimal results, pair Hydro Roots with Plagron's Hydro A+B base nutrient line, specifically formulated for hydroponic applications. On the additive side, Hydro Roots performs excellently alongside Green Sensation 0.1L (bloom intensifier for peak flowering) and Power Buds 0.1L (bud enhancer for dense structure formation). These three additives together constitute Plagron's classic hydroponic trio: root foundation (Hydro Roots), bloom explosion (Green Sensation), and bud structure (Power Buds). The 0.1L format of all three allows testing the complete trio across one cycle without significant investment — ideal for growers exploring Plagron's hydro systematics before committing to larger formats.

How much nutrient solution can I prepare with 0.1L Hydro Roots?
At the recommended 1 ml per litre dosage (1:1000), you produce 100 litres of nutrient solution from the 0.1L bottle. This covers a complete short cycle in a small tent (80×80 or 100×100 cm). Hydro Roots runs from vegetative phase through the third flowering week — stop thereafter to allow the plant to direct its energy toward flowering rather than continued root development during critical bloom weeks.
Can Hydro Roots be used in soil or only in hydroponics?
Hydro Roots also functions in soil and coco but is specifically formulated for hydroponic systems. Its 100% mineral composition prevents clogging in drip systems or pumps. In soil, organic alternatives like Power Roots often deliver more benefit through their contribution to soil biology. For hydroponics (DWC, NFT, drip), Hydro Roots remains the recommended choice for its clean, non-clogging operation.
Why stop after week 3 of flowering?
After week 3 of flowering, the plant must prioritise its available energy toward flower formation, not toward continued root development. Continuing Hydro Roots beyond this period would divert energy from the critical bloom phase and reduce final yield. The goal: that the plant possesses a fully developed root system at bloom onset to absorb the peak nutrient demand of the flowering period effectively.
Can Hydro Roots be combined with other brand nutrients?
As a mineral additive, Hydro Roots works universally with any hydroponic nutrient programme — including other brands such as Canna, House & Garden, or General Hydroponics. The entirely mineral composition means no incompatibility with other mineral base nutrients. Monitor the total EC value of your solution to avoid over-fertilisation, especially when combining multiple additives simultaneously in the reservoir.
