Strip out excess salts for a cleaner, purer-tasting harvest Canna Flush is a clearing solution used in the final 1-2 weeks before harvest to dissolve and wash out the excess salts and nutrient build-up that accumulate in the root zone after weeks of heavy feeding. Left in place, that residue carries through into a harsh, chemical aftertaste; flushing it out gives a cleaner-tasting crop. It also rescues an over-fertilised substrate without harming the beneficial micro-organisms living around the roots. Key Benefits Clears excess salts and nutrient residue from the medium before harvest Cleaner flavour and smoother finish in the final crop Corrects over-fertilisation without killing beneficial micro-organisms Works across most substrates and hydroponic systems Nutrient lock-out and harsh, salty-tasting crops Weeks of concentrated feeding leave mineral salts bound up in coco, soil and rockwool, which can trigger nutrient lock-out and leave an unpleasant taste in the finished product. Canna Flush actively dissolves these salt deposits so the plant burns off its own internal reserves before cut-down. How to Use All substrates and systems: 2ml per litre, used in place of your normal feed for the final 1-2 weeks before harvest Over-fertilisation rescue: run the same 2ml per litre solution through the medium to leach out excess salts, then return to normal feeding pH: adjust the flush solution to your medium's normal range before applying Feed Chart CANNA Flush · most substrates and hydroponic systems Application Per 1 L Per 10 L Final 1 to 2 weeks before harvest, in place of feed 2 ml 20 ml Over-fertilisation rescue, leaching the medium 2 ml 20 ml Note — Replaces the normal feed rather than being added to it. Adjust the flush solution to your medium's normal pH range before applying, then return to normal feeding after a rescue leach. Check pH and EC after mixing.
