The CO₂ Refill is an all natural CO₂ generator made from 100% organic ingredients. This safe and effective solution for CO₂ supplementation creates a blast of CO₂ that can reach 1200 PPM in a 12 x 12 x 12 foot area for up to 2 weeks (extraction dependent).

Activate the canister by adding 1 litre of warm water, placing the lid back on, removing the sticker on the lid, covering the small hole with your thumb and giving the bottle a quick shake. For optimal performance shake the canister once a day in a 12 x 12 x 12 foot area and once every second day in a 6 x 6 x 6 foot area.

Higher concentrations of carbon dioxide make plants more productive because photosynthesis relies on using the sun’s energy to synthesise sugar out of carbon dioxide and water. Plants and ecosystems use the sugar both as an energy source and as the basic building block for growth.

More carbon dioxide available means pores on the surface of plant leaves regulating evaporation (called the stomata) can close slightly, this helps the plant save alot of water. They still absorb the same amount or more of carbon dioxide, but lose less water.
