A CO 2 tank and regulator is used to
enrich the air. CO 2 laden air
increases the growth rate
phenomenally.
Step By Step
Plants do best in indoor gardens when
they are supplied with CO 2. Growers
usually choose:
- An open door or curtain is often the
best solution for small spaces which
have a large surface-to-air ratio. - External ventilation to blow out the
used air and draw in new air. This is
usually adequate for small rooms. - A CO 2 enrichment system. This
consists of a tank and regulator flow
meter and either a timer or other
automatic valve. This increases the
growth rate of the plants phenomenally. - A water heater or gas stove may
supplement the garden with CO 2.
