Co2 exhale – 1 x 1 x 2 mtr doser

The Exhale CO2 doser is a mushroom-based bag designed for 1 x 1 x 2 metre grow rooms. It generates CO2 through natural mycelium respiration, providing continuous supplementation for over six months +  This passive system integrates with hydroponic nutrients and additives, maintaining elevated CO2 levels in enclosed spaces to support photosynthesis. No electricity, timers, or regulators required. Simply hang or place in the grow area for sustained release. Ideal for small-scale indoor cultivation requiring consistent CO2 enrichment as part of nutrient programs.
