Boost CO2 levels in your grow room by introducing one of these excellent gas burners and – as long as all other environmental factors have been optimized – you can expect to see plants perform much better than ever before!

Carbon dioxide is a key fuel for photosynthesis – the amazing process that also combines water and light to give your plants the energy they need to develop. If you add a Growth Gas Generator and strive to provide the right amount of CO2 (much more than resides inside a typical non-treated grow room), this all-important element can produce phenomenal results!

Plants will grow up to 40% faster than the average rate, leading to larger stems, leaves, flowers, etc. and significantly bigger yields. Other tremendous benefits include greater resistance to environmental stresses (e.g. extreme temperatures and pests/diseases), enhanced performance at low light settings and improved root/top ratios.    

Featuring a simple plug and play design, the Growth Gas Generator conveniently comes available in four different sizes to suit all types of grow room (ranging from 20m² to 4000m²). It can safely use propane or natural gas (supplied as being ready to run on propane with conversion kit for natural gas included) and has the ability to push atmospheric CO2 up to 1000ppm – letting you create the perfect growing environment!

NOTE: Growth Gas Generators do not come with the hose or regulator shown in the pictures.
