Canna Flush — Pre-Harvest Substrate & Plant Cleansing

Canna Flush — Pre-Harvest Substrate & Plant Cleansing Agent

Canna Flush is designed to purify substrates and plants by eliminating excess nutrients — necessary because excess nutrients negatively impact your next growth cycle (excessive fertilisation residue, poor plant nutrition uptake). Used just before harvest, Flush actively pulls accumulated nutrients out of the plant tissue, resulting in cleaner final flavour and aroma at harvest.

Why growers choose Canna Flush:

• Actively removes excess nutrients — more effective than just stopping feed for 1-2 weeks
• Improves final flavour and aroma — clean finish vs fertiliser-tainted flowers
• Purifies both substrate and plant — addresses both medium and tissue accumulation
• Used just before harvest — final 1-2 weeks before cutting
• Resets substrate for next cycle — useful in reusable-medium setups (coco, clay pebbles)
• Canna reference quality — consistent batch performance, Canna's proven formulation standards
• Compatible with any feeding programme — not Canna-only, universal flush

Who it's not for:

Used only in the final 1-2 weeks before harvest — not a mid-grow product. If you're using Advanced Nutrients Flawless Finish, HydroTops Flush, or similar already, pick one — don't double-flush. Apply per the pack instructions; over-flushing can stress plants into early leaf fade that actually reduces quality. For strict-organic growing, BioBizz Bio-Heaven or natural water-only flushing may be more appropriate.
