CO2 can be administered in many ways, but the simplest way is to use effervescent tablets. Effervescent tablets are made by pressing an acid and a base together. When these tablets come into contact with water, a reaction occurs. During this reaction CO² is released, as well as water and some other active substances.

1 tab is enough for 200 litres. It is advisable to give the plants an extra boost of CO2 twice a week.
