Cyco Ryzofuel — Premium Kelp Root Stimulant for Vegetative Growth
Best for: Growers wanting serious root development during veg without the Advanced Nutrients price tag
Our thoughts
This is the root stimulant that's been turning heads. Made from enzymatically digested Tasmanian Bull Kelp—not the standard Norwegian stuff—it's packed with naturally higher cytokinins and auxins. Growers are genuinely switching from Advanced Nutrients because Ryzofuel works just as well for a fraction of the cost. One we recommend a lot for coco-based systems.
Cyco Ryzofuel is a liquid kelp root stimulant designed to rapidly accelerate new root growth and development during the vegetative stage. Made from enzymatically digested Tasmanian Bull Kelp, it delivers a concentrated dose of naturally occurring plant hormones—cytokinins, auxins, and gibberellins—that actively promote root branching, stem development, and healthy leaf formation. It's formulated specifically for coco-coir cultivation and integrates seamlessly into any base nutrient programme.
How it compares
Ryzofuel sits in the premium-performance, entry-price bracket of vegetative growth additives.
- Significantly cheaper than Advanced Nutrients Tarantula or Voodoo Juice (roughly one-third the cost per litre)
- Outperforms General Hydroponics Rapid Start and House & Garden Excelurator due to higher natural hormone concentration in Tasmanian vs Norwegian kelp
- Clean enzymatic processing means no synthetic fillers, just pure kelp extract
- System-optimised for coco but works in any medium
You're getting premium-brand performance at value-brand pricing. That's why growers are jumping ship from pricier lines.
Usage guidance
Ryzofuel is a vegetative-stage additive used alongside your main nutrient feed.
Standard application
Add to your nutrient tank at 0.5ml per litre (1:1000 ratio). Run through your feeding schedule from propagation through late vegetative growth.
In coco systems
Works best with run-to-waste feeding. The enzymatically processed kelp is clean and won't block drippers or emitters. Most growers run it continuously through veg, then drop it at the flowering transition.
With transplants and seedlings
Use at full strength to support root establishment after potting up. Plants typically show visible response within 3-5 days.
Compatible with your existing lineup
Ryzofuel complements any two-part base nutrient. Popular pairing: Cyco A+B with Ryzofuel through veg, then Bud XL and Swell at flower. But it's not exclusive to Cyco—works just fine with other brands.

Our take
Ryzofuel is the real deal. Higher hormone levels, cleaner processing, and a price point that leaves budget for other essentials. It's not just a cheaper version of something else—it's a genuinely better kelp source, and growers have noticed.
Good time to pick up while stock lasts. Does exactly what root development should do, and won't need replacing with something else once you've dialled it in.
