Cyco Nutrients - Platinum Series - Ryzofuel - Root Stimulant for Faster, Healthier Root Growth
Best for: growers who want to speed up root development during the vegetative stage and build a healthier root system.
Our thoughts
Root health underpins everything else a plant does above the medium, so a root stimulant like this earns its place early in the grow rather than being an afterthought. Ryzofuel is a veg-stage product specifically, so time it right and don't expect it to do a late-flower job. Worth budgeting for if you're already running a full Cyco Platinum Series programme.
Ryzofuel is a root stimulant designed to be added during the vegetative growth stage. It's formulated to speed up the development of fresh roots while also supporting the health of roots the plant has already established, giving the plant a stronger foundation to draw nutrients and water through for the rest of the grow.
Because root development underpins how efficiently a plant can take up everything else you feed it, a dedicated root stimulant used early in veg is generally considered good practice by growers running a structured additive programme, rather than relying on the base nutrient alone to support root growth.
How it compares
Root stimulants are one of the most competitive additive categories in the hobby growing market.
- House & Garden Roots Excelurator is one of the best-known root stimulants and a common reference point for this whole category.
- Canna Rhizotonic takes a similar veg-stage, root-focused approach and is widely used alongside Canna's own base nutrients.
- Great White, a mycorrhizal inoculant, works on root development through a different mechanism (beneficial fungi rather than a liquid stimulant) but is often shortlisted against products like Ryzofuel.
Ryzofuel's advantage for existing Cyco users is consistency, it's formulated to slot into the same Platinum Series feed chart rather than needing separate dosing logic from a different brand.
Usage guidance
Use it through the vegetative stage rather than into flower.
Timing
Add Ryzofuel during the vegetative growth stages, from early veg through to the point you switch to flower.
Dosing
Follow the dose rate on the bottle or Cyco's Platinum Series feed chart, dosing it alongside your base Grow nutrient.
Consistency
Use it on a regular schedule through veg rather than as an occasional top-up, since root stimulants generally work best with steady use.

Our take
Ryzofuel tackles the part of the plant you don't see but that everything else depends on. A healthier root system in veg pays off through the rest of the grow, which is the whole logic of using a dedicated root stimulant at this stage.
Does exactly what it should, day in, day out. Worth picking up if you're building out a full Cyco veg routine.
