These fizzy CO2 tablets, with extra slow and gradual release of carbon dioxide, provide plants with the greatest quantity of CO2 they can absorb through their leaves. Can be used in the nutrient tank but we recommend using the CO2 in a separate bucket of water in your growing environment.
As CO2 is only use by the plants in photosynthesis(during light hours), no CO2 is absorb during dark hours, so make sure you add the tablets in maximum light hours for the best results.
60 Slow Release CO2 tablets come in a handy tub.
