Canna Flush from Canna is an additive that breaks down excess nutrients on plants and substrates.
Canna Flush can be used with all growing media. It's highly recommended in cases of over-feeding because it purifies the substrate without eradicating the benefitial bacteria, which is necessary for the proper development of marijuana plants.
Using Canna Flush before the end of the flowering period ensures a clean and tasty harvest.
