Evoponic Mother Nature CO2 Bucket Refills – Natural CO2 Generator Refill

Keep your CO2 levels topped up with the Evoponic Mother Nature CO2 Bucket Refill — a natural, bacteria-driven CO2 generation system designed for indoor growing environments. Each refill is formulated to sustain consistent CO2 output for a minimum of 6 months, helping maintain elevated PPM levels for vigorous plant development.

The unique blend of beneficial bacteria produces a substantial volume of CO2. The 10L refill is sized to cover a 2.4m × 2.4m grow tent, while the 5L covers a 1.2m × 1.2m tent — both capable of raising CO2 PPM to 800–1,200 under optimal conditions. Once spent, the contents can be added directly to your compost heap.

This listing is for the refill only — bucket not included.

Usage Notes

CO2 output will naturally reduce over time, more noticeably after 6 months. For best results, position the bucket at canopy height to allow CO2 to fall naturally through the growing area.
