Plagron Power Roots — Organic Root Stimulator for Strong Early Growth
Best for: Growers wanting to build dense root systems and maximise nutrient uptake without premium pricing
Our thoughts
Power Roots does one job properly: it gets roots to branch, fill containers faster, and recover well from transplant stress. It's organic, economical, and mixes into your feeding schedule without faffing about. One a lot of growers use because it actually works and doesn't cost the earth.
Plagron Power Roots is an organic root development additive formulated with humic acids, seaweed extract, vitamins, and hydrolysed proteins. It's designed to strengthen root systems during vegetative growth, helping plants build the dense, branching root structure they need to absorb nutrients properly and resist root diseases. Works quickly, absorbs virtually immediately, and plays nice with any hand-fed growing setup.
How it compares
This sits in the organic root stimulator tier alongside CANNA Bio Rhizotonic and Dutch Pro Take Root, but at a lower price point.
- Organic formulation with proven humic and seaweed base — no synthetic shortcutting
- Highly concentrated, so a little goes a long way across hand-feeding and drip setups
- Significantly cheaper per litre than premium alternatives, especially in larger sizes
- Designed specifically for soil and coco — not suitable for hydro systems (Plagron make Hydro Roots for that)
You're getting a working root booster that growers genuinely rate, without paying for a brand name premium.
Usage guidance
Power Roots is added to your feed water at a simple ratio:
Application rate
Add 1 ml per litre of water. Use this concentration with every watering during vegetative growth, stopping in week four of flowering.
Transplanting and establishment
This is where Power Roots shines. Use it immediately after moving plants to reduce transplant shock. The inositol in the formula helps boost root metabolism during stress, speeding recovery and establishment.
Compatibility
Works with any Plagron base nutrient (Terra, Cocos, or Hydro ranges) and integrates cleanly into hand-fed soil and coco setups. It also supports beneficial microbial life in your substrate, which improves long-term health.
Storage note
If your bottle smells herbal or looks slightly cloudy, that's normal. The organic ingredients naturally develop a smell and mild cloudiness over time — harmless to plants and a sign the formula is doing its job.

Our take
Power Roots is a proper organic root stimulator that does exactly what it should: builds roots faster, thicker, and more resilient. It's concentrated, economical, and integrates seamlessly into standard feeding schedules.
