The TNB CO² Refill Pack gives growers the ability to reuse their existing Enhancer bottle while saving money and reducing their environmental footprint at the same time.

Simply empty the contents of the original bottle and give the bottle a quick rinse. The contents of the Refill Pack can be added and instantly CO² is once again available for use. 

Boosting plant production and improving overall health, CO² is an essential element of photosynthesis and often one of the most overlooked components of plant growth.

The TNB CO² Refill Pack consists of the same great recipe while combining convenience and an amazing option for those looking for passive CO².

Research has shown that plants can use up to five times the CO² that naturally occurs in the air. With The Enhancer known for delivering levels of CO² only comparable to a propane or natural gas burner, there is no question many growers will be turning in their tanks and introducing CO² with this safer, much less expensive and all natural method.
