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