How to Use GROW MAX CO2

A continuous shower of CO₂ directly onto your plants is the most efficient way to deliver CO₂. Placing the GROW MAX CO₂ Bag slightly above the level of your plants will ensure they receive the CO₂they need 24 hours a day for up to 6 months.

GROW MAX can be used for both vegetative plant growth as well as for fruit and flower production. If you have a ventilation system, place the GROW MAX bag in close proximity to the fresh air intake. CO₂will be drawn upwards through the canopy.
