Canna Flush Nutrients 250ml, 1l, 5l Plant Food

CANNA FLUSH is an additive that helps remove excess nutrients from your plants and also your growing media.

Canna Flush can be used when over feeding has occurred and you want to minimise plant damage or when its time to harvest, and you would like the taste of your crop to shine through! Canna Flush will do this without affecting the microlife (beneficial bacteria and fungi) that may be present in your substrate.

Why should you use CANNA FLUSH?

When used just before harvest it makes sure the plant gets rid of all excess, which will lead to a clean and tasteful harvest.

CANNA FLUSH effectively cleans the substrate without killing any useful bacteria or beneficial fungi, as can be the case when you use reverse osmosis or de-mineralised water.

It can be used on all substrates.

CANNA FLUSH is recyclable.
