The TNB CO2 Refill Pack will now give 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 instant 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.
