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 on your next growth cycle. This could lead to over-fertilisation or malnutrition, for example.
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 and what's more...CANNA FLUSH is recyclable!
