The Hydrogarden CO2 Release Kit comes ready assembled and all you will need to do is attach it to a suitable vapour release CO2 bottle. It is important that you ensure the removable fibre washer (on the regulator stem) is fitted to the nut joining the gas bottle for a complete seal. The Release Kit will come complete with all instructions and ample CO2 tubing. Simply attach the tubing to the barbed fitting on the base of the regulator . Note that the barbed fitting is quite a lot smaller than the tubing. This is easily rectified by attaching a cable tie or ratchet clip around the tubing and fitting to give a tight fit.

Danger: CO2 is an asphyxiant in high concentrations - please monitor CO2 levels to ensure there is no build-up/ danger to humans or animals.

Recommended, especially if growing under LED lighting.
