• Canna Flush 1 Liter

CANNA FLUSH is a product to clean substrates and plants from any excess nutrients. This is necessary, because excess nutrients can have a bad influence your next growth cycle. They could lead to over-fertilisation or malnutrition, for example.

Why should you use CANNA FLUSH?


When used just before harvest it makes sure the plant gets rid of all excess, which will lead to a clean and tasteful harvest.

CANNA FLUSH effectively cleans the substrate without killing any useful bacteria or beneficial fungi, as can be the case when you use reverse osmosis or de-mineralised water.

It can be used on all substrates.

CANNA FLUSH is recyclable.
