CANNA FLUSH is an additive to clean substrate and plants of any excess nutrients. To be used in the case of over-fertilisation, it effectively cleans the substrate without killing any useful bacteria or beneficial fungi which can be the case when using reverse osmosis (RO) or de-mineralised water. When used just before harvest, it makes sure that the plant expels excess minerals which will lead to a clean and tasteful harvest. It prevents side effects to the flavour of your crop by flushing all excess salts from crop and substrate. CANNA FLUSH can be used on all growing substrates and it is fully biodegradable.
Available in: 250ml, 1L, 5L
