Canna Flush is an additive that is used to counter overfeeding, nutrient lock-out and to prepare plants for harvest.
Suitable for use in hydro, coco and soil, it can restore plants that have been given too much fertiliser without removing beneficial bacteria or fungi. Highly recommended for use the week before harvest to ensure a cleaner, better tasting product.
Available in 250ml, 1l or 5l sizes.
