Canna Calmag Agent. 

Let’s talk about water. That life-giving, transparent nonsense you assume is just “fine” because it comes out of a tap.

But if you're serious about indoor growing - whether it’s a micro cupboard in Manchester or a full-blown hydro jungle in Hull - then you’ll already know that water quality can be the silent killer of your plants. And this is where Canna Calmag Agent charges in like a nutritional SWAT team. 

Your Water is Probably Rubbish. 

From the horticultural masterminds at Canna, who are about as close as you get to plant whisperers in lab coats, Canna Calmag Agent is an unapologetically potent cocktail of calcium and magnesium.

These two minerals might not sound glamorous, but when your plants start yellowing at the edges or falling over like Victorian aristocrats with the vapours, it’s usually because they’re screaming out for one or both.

What makes Canna Calmag Agent special isn’t just that it contains calcium and magnesium - it’s the way it delivers them. At a scientifically dialled-in 3:1 calcium to magnesium ratio, this formula doesn’t just tick boxes.

It optimises nutrient uptake, fortifies cell structure, and boosts overall plant resilience. We’re talking about visibly stronger stems, more efficient photosynthesis and roots that dig in like they’ve just been promoted.

Perfect EC.

The clever part? It doesn’t matter whether your tap water is soft, normal, hard, or completely atrocious - Canna Calmag Agent can bring balance to the madness. If your EC (electrical conductivity) is under 0.4, congratulations, you’ve got soft water.

Add Canna Calmag Agent and you’ll bring it right up to a usable 0.4, giving your base nutrients something to actually interact with.

If, on the other hand, your EC is over 0.5 and your water tastes like the inside of a kettle, reverse osmosis it, mix it back to around 0.2, and then add the Calmag Agent to hit that magical 0.4 sweet spot.

Complete Nutrition.

Poor-quality water doesn’t just slow things down - it invites disaster. Sodium and chloride (the usual suspects in so-called “bad water”) can block essential nutrient uptake, stunt growth, and even tip your pH so far off-course you’d need a compass to find your way back.

But with Canna Calmag Agent, not only do you buffer the EC, you also stabilise the pH - giving your base nutrients the optimal environment to do their job properly.

Highly Concentrated. Lasts Ages. 

Oh, and did I mention it’s highly concentrated? That means fewer glugs from the bottle, less plastic waste, and more value over time. Available in 1L and 5L bottles, it's suitable for everyone from casual grow tent tinkerers to those running hydroponic setups the size of small warehouses.

Canna. The Only Way.

In a world where your plants rely on your tap water - which, let’s face it, is often about as reliable as a second-hand umbrella - Canna Calmag Agent is your invisible insurance policy. It won’t win you any beauty contests. But it will keep your plants standing tall, green and utterly unstoppable. And that, frankly, is what matters.
