Rhizotonic. Like Meth for your Roots. 

The trouble with most root stimulators is that they fall into two categories. Useless, or worse than useless. Like feeding your plant a spoonful of hot gravel and expecting it to flourish. But then there’s Canna Rhizotonic — and it’s in a category all of its own. Made by the nutrient-slinging savants at Canna, this isn’t just a root booster. This is the root booster. The original, the benchmark, the one that everyone else is still trying — and failing — to copy. 

Bigger Roots = Bigger Fruits. 

Let’s get one thing straight. If your plant’s roots are second-rate, your harvest will be too. Doesn’t matter what lights you’re using, how perfect your environment is, or whether you whisper bedtime stories to your seedlings. Without a thriving, aggressive root zone, your plant is essentially a sponge in a pot. Canna Rhizotonic changes that immediately and dramatically.

An Underground Revolution.

Derived from the unassuming but utterly brilliant Ascophyllum nodosum seaweed, Canna Rhizotonic is loaded with over 60 microbiological agents that kick root growth into overdrive. We’re not talking about vague improvements either. This is the botanical equivalent of throwing high-octane rocket fuel into a sapling’s DNA. It stimulates new root hair production, accelerates root expansion, and significantly improves the uptake of water and nutrients — the two things your plant actually needs to do anything useful.

Smart & Powerful.

The formula isn’t just powerful, it’s smart. Thanks to its minimal impact on EC levels when diluted — just 4ml per litre for standard use — Canna Rhizotonic won’t throw your nutrient balance out of the window. That’s critical during germination, where even the slightest excess can ruin your precious seeds. In fact, Rhizotonic actually helps soften the seed case, encouraging the taproot to push out and explore. That alone makes it worth keeping in your arsenal.

Natural Seaweed Extract. 

But where Canna Rhizotonic really earns its stripes is stress recovery. If your plant has been repotted, manhandled, droughted, or subjected to any of the usual human mistakes, Rhizotonic steps in like a well-paid trauma doctor. The natural compounds within the seaweed extract trigger the plant’s internal defence mechanisms, boost carbohydrate production, and restore vigor faster than you’d think possible. Plants bounce back visibly within days



The Building Blocks of Flavour.

It also improves microbial activity in the substrate, meaning it’s not just feeding the roots — it’s feeding the life around the roots. This leads to better nutrient cycling, stronger immune responses, and, interestingly, an improvement in the taste and quality of the final product. That’s thanks to increased chlorophyll, flavonoids, and phenolic content — the biochemical building blocks of flavour.

For Soil, Hydro & Coco.

Use it in soil, hydro, coco, or even as a foliar spray if you're in a hurry. Canna Rhizotonic is stable, shelf-ready for up to two years, and works in literally any system — drip, recirculating, flood-and-drain, or the classic water-it-yourself-and-hope-for-the-best approach.

In short, Canna Rhizotonic isn’t just the world’s best root stimulator. It’s a recovery tonic, microbial booster, and growth accelerator all rolled into one. It doesn’t just grow roots. It builds foundations. And if you want your grow to be more than just green fluff, then Rhizotonic is the tool you absolutely need in your kit. Accept no substitutes.
