Canna Flush. 

Imagine feeding your plants the best nutrients money can buy. They're green, vigorous, and bursting with potential.

But then comes harvest, and instead of that clean, rich taste you were hoping for, you're met with something that reminds you of licking a garden centre. That’s what happens when all those beautiful nutrients don’t leave the building in time. And that’s precisely why Canna Flush exists. 

It's Like A Plant Detox. 

Canna Flush is what you reach for when your plants need a detox - not the kind where they drink lemon water and chant at the moon, but a proper, scientific cleanse.

Developed by the lab-coat-wearing, hydroponics-obsessed experts at Canna, it’s engineered to remove excess nutrients from both the plant and the growing medium, without ripping out the good stuff along the way.

Unlike those slapdash methods involving reverse osmosis water or demineralised solutions that annihilate your microbial life with all the subtlety of a bulldozer, Canna Flush works with precision.

It doesn't murder beneficial bacteria or fungi. It targets the stuff you don't want - the residual mineral build-up that can make your end product taste like a fertiliser sandwich - and helps flush it out gently but effectively.

Essential Pre-Harvest Prep.

And here’s the kicker: Canna Flush isn’t just for panicked growers looking to rescue overfed plants (although it’s brilliant at that). It's also a crucial tool in the final two weeks before harvest. Why? Because it prepares your plants for the finish line by removing any lingering nutrient excess, giving you a cleaner, smoother, more natural flavour. The difference is immediate and unmistakable.

Keep Your Plants Pure.

Technically, here’s what’s happening. Canna Flush contains compounds that latch onto mobile nutrient ions within the plant and growing medium.

Once bound, these nutrients are held in suspension, allowing them to be washed out during your next watering. It’s available in two sizes - ideal whether you’re running a compact indoor setup or managing something a bit more… ambitious.

If you're growing in soil or a soilless mix, you’ll dilute 20ml per 10 litres of water and flush it through until you get proper drainage. Follow up with a rinse using plain tap water, and then resume feeding as normal. For hydroponic systems, you’ll up the dose to 40ml per 10 litres, apply it as the final feed of the day, then flush again with tap water. Simple, effective and surprisingly unmessy.

Tastes Better. Is Better. 

But Canna Flush isn't just for living plants. If you’re reusing inert substrates like clay pebbles, it’s your best friend there too. Soak them in a 40ml/10L solution for 24 hours, rinse, repeat if necessary and you’re ready to go again - no residue, no contamination, no stress.

Don't Cut the Final Corner.

Whether you’re course-correcting after an accidental overfeed or prepping for a harvest that actually tastes like something worth eating, Canna Flush is the no-nonsense tool you need. It’s not glamorous. It won’t make your leaves glow. But what it will do is make your end result taste infinitely better - and that, after all the effort, is the bit that matters.
