Canna Flush is an additive used to clean the substrate and plants of any excess nutrient. To be used in the case of over fertilisation, it effectively cleans the substrate without killing useful or beneficial bacteria or fungi as can be the case when using RO or demineralised water. When used just before the harvest it makes sure the plant gets rid of excess salts which will lead to a clean and tasteful harvest.
