Cyco Nutrients - Platinum Series - Kleanse - Salt Flush for Cleaner Feeding Right to Harvest
Best for: growers who want to clear out nutrient salt build-up before harvest or when correcting a lockout.
Our thoughts
A flush product isn't glamorous, but if you've ever pulled a plant with crusty white salt build-up on the top of your medium, you know why it matters. Kleanse does the specific job of getting locked-up nutrients back into a usable form so your plants can actually take them up, or clearing the substrate out properly before harvest. It's a cheap bottle that solves an annoying, common problem.
Kleanse is a flushing product designed to dissolve salt build-up in your growing medium, making previously locked-out nutrients available to the plant again. It works by solubilising micronutrients, cationic nutrients and metals that have accumulated in the root zone, which is a common issue in any feeding programme that relies on mineral salts.
It's typically used in two scenarios: as a pre-harvest flush to clear excess nutrient salts from the growing medium, or mid-grow if you're seeing signs of nutrient lockout despite feeding correctly, where dissolved salts are blocking uptake rather than a genuine deficiency being the cause.
How it compares
Flush products are a well-established category, and Kleanse does the same core job as the market leaders.
- General Hydroponics FloraKleen is probably the best-known flush/cleaning agent and the most common comparison point.
- Canna Flush is another widely used option aimed at the same pre-harvest clean-out.
- Advanced Nutrients Flawless Finish takes a similar approach for growers who want a clean taste and clear runoff before harvest.
All flush products are chasing the same outcome, cleaner substrate and better nutrient availability, so the choice between them often comes down to which nutrient brand you're already running.
Usage guidance
Use it as a dedicated flush rather than mixing it into your normal feed schedule.
Pre-harvest flush
Run Kleanse through your medium in the final period before harvest, in place of your normal nutrient feed, to help clear excess salts from the substrate.
Correcting lockout
If you're seeing lockout symptoms (leaf discolouration or poor uptake despite correct feeding), flush with Kleanse before resuming your normal nutrient programme.
Dosing and runoff
Follow the dose rate on the bottle, and where possible flush until runoff EC drops to a sensible level for your growing medium.
