Using a pencil or screwdriver pierce 3-6 holes in the bag roughly 1 inch from the top. Do not make contact with the contents of the bag.


If the bag has not begun emitting co2 within 3 Days , carefully insert 1-2ml of clean water via an existing hole to assist the activation.

Using the cable tie supplied, hang the bag above your plants . situate the bag close to air intake to ensure co2 is not expelled immediately.

The bag will start to produce co2 over 2-3 days at an optimum temperature of between 25-30 degrees.

Optimum humidity levels are important; therefore, if the bag produces too much moisture , simply pierce the bottom of the bag with a pin to drain excess moisture. Do not hang the bag close to lamps, lights of other heat sources.

The recommended room size is 5m2 - 15m2. The bags will produce co2 for between 2-3 months dependant on ventilation , heat humidity and amount of holes pierced into the bag.
