Description
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
