Dutch Hydroponic Nutrients
CANNA Nutrients — Hydroponic Science Built for Serious Growers
If you've spent more than five minutes in a grow shop, you already know CANNA. The Dutch nutrient house has been the gold standard for hydroponic and coco growers since the early nineties — stocked in over 95% of grow shops worldwide and voted the world's number one plant technology brand by growers globally. That reputation didn't come from clever marketing. It came from genuinely superior formulas, a two-year average development cycle per product, and a full in-house production chain that keeps quality locked down from lab to bottle.
At The Grow Guys, we stock the full CANNA range — nutrients, growing mediums, boosters, and additives — ready to ship Australia-wide. Whether you're running a coco drain-to-waste, a recirculating hydro system, or a potting mix garden, CANNA has a system built specifically for your method.
Why Growers Rate CANNA
Two Years Per Formula
No CANNA product hits the shelf until it's spent an average of two years in development. A full team of specialists tests every angle before a single bottle is sold.
Full In-House Production Chain
From the lab to the logistics dock, CANNA controls the entire process. No outsourcing, no shortcuts — just consistent quality from batch to batch.
Built for Coco, Hydro and Soil
CANNA doesn't make a one-size-fits-all nutrient. Each formula is designed specifically for the growing medium it's used in — coco, rockwool, hydro, or potting mix.
Voted Number One Worldwide
Professional growers in fourteen countries swear by CANNA. That's not marketing spin — it's the result of decades of results in real grow rooms and real gardens.
Balanced Trace Element Formulas
CANNA's formulas are built around precisely calibrated blends of macro and trace elements — matched to each growing medium for maximum uptake and minimal lockout.
Award-Winning Dutch Science
CANNA took first prize at one of Holland's most prestigious horticultural expos for innovation in plant nutrients — recognised internationally before the internet existed.
The CANNA Story
CANNA started out of frustration. The founders looked at the fertiliser options available to serious growers in the late eighties and didn't like what they saw — a narrow, uninspiring range that gave growers very little to work with. So they built something better. Their first nutrients, CANNA Vega and CANNA Flores, were so effective that grow shops noticed the difference in crop quality immediately. From that point, the business grew fast — driven not by hype, but by results.
What sets CANNA apart from the rest of the market is the depth of their research operation. They run their own laboratory, their own growing trials, and their own extended field testing across multiple countries before any new product is released. When CANNA says a product works, it's because they've watched it work — under controlled conditions, in real-world setups, across different climates. The average time from concept to shelf is two years. In an industry full of short-term hype, that kind of patience is rare.
Today, CANNA is distributed across Europe, Australia, North America, the Middle East, and Africa. It was CANNA who pioneered the 1:250 standard mixture ratio that's now used industry-wide. They don't chase trends. They set the standard — and then they hold it.

Grow Guys Tip
CANNA systems are built to work as a matched set — base nutrients, boosters, and medium. If you're running CANNA Coco A&B, you'll get better results pairing it with CANNAZYM and Rhizotonic than mixing in random additives from other brands. The formulas are balanced against each other. The more you stay within the CANNA ecosystem, the less troubleshooting you'll need to do. If you're not sure which system fits your setup, get in touch — we run CANNA ourselves and can point you straight.
Common Questions About CANNA
What is CANNA and where is it made?
CANNA is a Dutch plant nutrition company that's been producing hydroponic nutrients and growing mediums since the early 1990s. All products are developed and tested in-house at their facility in the Netherlands, with a full on-site laboratory and research program. CANNA controls every stage of production — from development through to packaging and logistics — which is a big part of why their quality is so consistent.
Is CANNA good for coco growing?
Yes — CANNA Coco is one of the most respected coco nutrient systems available, and for good reason. It's formulated specifically to account for coco coir's natural cation exchange behaviour, which means you won't run into the calcium and magnesium issues that trip growers up when they use generic nutrients in coco. The full CANNA Coco system — paired with CANNA's own buffered coco medium — is a reliable, tried-and-tested combination that works for beginners and experienced growers alike.
What is the difference between CANNA Vega and CANNA Flores?
CANNA Vega is the vegetative-stage formula — higher in nitrogen and designed to support strong structural growth and healthy root development. CANNA Flores is the bloom-stage formula — phosphorus and potassium-forward, formulated to drive flower and fruit development once you've flipped to a 12/12 light cycle. They're CANNA's original products, now sold as CANNA Hydro Vega and CANNA Hydro Flores, and they remain the backbone of the CANNA hydroponic range.
