Quick Answer

Root stimulant made from enzymatically digested Tasmanian bull kelp, one of the richest natural hormone sources available.
Works on the plant rather than the reservoir. It tells roots to grow instead of feeding them, which is why it does its best work on cuttings and transplants.
Barely touches your EC, so it layers onto any feed without recalculating anything.
Built for propagation and vegetative growth. Also used to moisten clone blocks before cuttings go in.
Ships fast from within Australia.

CYCO Ryzofuel

CYCO Ryzofuel is a Platinum Series root stimulant made from enzymatically digested Tasmanian bull kelp. Kelp has been used in horticulture for decades because it carries naturally occurring plant growth hormones, mainly cytokinins and auxins, which are the signals that tell a plant to put out new roots. Ryzofuel is CYCO's kelp product, used to get roots established fast in seedlings, cuttings and young plants.

Why a Stimulant and Not a Fertiliser

The registered analysis is 0.2% soluble potash, and that low number is the point rather than a shortcoming.

A fertiliser supplies the raw materials. A stimulant changes what the plant does with them. Ryzofuel is the second kind. The active part is the hormone and trace mineral content of the kelp, which doesn't appear in a guaranteed analysis because hormones aren't declarable nutrients. You could have a reservoir full of perfect nutrition and still get slow, sparse roots on a fresh cutting, because at that stage the limiting factor is the signal to grow them, not the food to build them with.

That's also why it adds almost nothing to your EC. You get the effect without crowding the feed you've already dialled in, which matters on seedlings and clones where a strong nutrient solution does more harm than good.

Where it earns its money is propagation and transplant, when roots are being built from scratch or recovering from disturbance. On an established plant in a system already running well, expect less. CYCO specify vegetative growth and propagation, so it isn't a flowering product.

Key Benefits

Faster Root Establishment: Kelp-derived cytokinins and auxins drive root initiation in cuttings, seedlings and transplants.
Over 50 Trace Elements: Kelp naturally carries a broad mineral profile alongside the declared potassium.
Safe on Young Plants: At 0.2% potash it barely moves EC, so it suits seedlings and clones that can't handle a strong feed.
Doubles as a Block Soak: Used as a weak solution to pre-moisten clone blocks before cuttings are placed.

How and When to Use

Run it through the vegetative stage to build root mass, or as a weak solution to lightly moisten clone blocks before placing cuttings. Don't oversaturate blocks, since an unrooted cutting rots far more easily than it dries out.

It also suits outdoor use on trees, bulbs and garden beds, where kelp has a long track record at transplant time.

Frequently Asked Questions

What's actually in Ryzofuel?

Enzymatically digested Tasmanian bull kelp, with a registered analysis of 0.2% soluble potash. The working part is the kelp's natural growth hormones and trace minerals, which don't appear on a guaranteed analysis because hormones aren't declarable nutrients. That's what makes it a stimulant rather than a fertiliser.

Why is the NPK so low?

Because it isn't trying to feed the plant, it's trying to trigger root growth. Those are different jobs. The low concentration is an advantage on cuttings and seedlings, which are easily burnt by a strong feed but still need a push to root.

Can I use Ryzofuel through flowering?

CYCO specify vegetative growth and propagation. Root establishment is an early-cycle job, so there's little to gain from running it in flower.

Can I use CYCO Ryzofuel for cloning and propagation?

Yes, that's where it does its best work. A weak solution is used to lightly moisten clone blocks before cuttings go in. Don't oversaturate the block, since an unrooted cutting is far more likely to rot than to dry out.

Is Ryzofuel the same as a rooting gel?

No, and they're commonly used together. A gel such as CYCO Cyclone is applied directly to the cut stem at a set hormone concentration. Ryzofuel is a dilute solution used in the block or reservoir. Gel on the cutting, Ryzofuel in the block.

Can I use CYCO Ryzofuel on outdoor plants, trees and bulbs?

Yes. Kelp has a long history of use at transplant time on trees, bulbs and garden beds, and Ryzofuel suits outdoor use as well as indoor systems.

What is the shelf life of CYCO Ryzofuel?

Unopened, 2 years when stored cool and out of direct sunlight. Once opened, use within 12 months. Keep it cool, since heat degrades the hormone content that makes kelp worth using in the first place.

Does CYCO Ryzofuel ship fast within Australia?

Yes, CYCO Ryzofuel ships from within Australia with fast tracked delivery Australia-wide. Most east coast orders arrive within 2 to 5 business days. WA, NT, and TAS orders typically arrive within 5 to 12 business days.
