Basic Equipment Rundown
plants require CO2 to photosynthesize. CO2
is present in relatively low quantities,
300-450 Part Per Million or "ppm"
in normal everyday air. But plant growth
can be increased and accelerated by as much
as 35% if the level of CO2 is increased
to 1500 ppm.
with all of the other aspects of hydroponics,
controlling the CO2 level within the area
is crucial to maintaining a high level of
productivity. Todays hydroponic and lighting
systems are designed to provide the most
efficient method for distributing nutrients
and providing usable light however, without
proper ventilation and/or an adequate supply
of CO2, the plants may actually be starving!
Starving because of too much food and/or
light, and not enough CO2 for the leaves
to achieve a high level of photosynthesis.
your CO2 lamp during the light cycle, i.e. when
the lights are turned on. You can use a timer
to alternate your exhaust fan on & off to
give the CO2 a chance to build up in your grow
||Calculate how much
oil is required in your lamp to burn for the light
period. Fill only with enough to burn for this
period, as the lamp will affect the development
of the plants if it interrupts the dark cycle.
||Don’t place the
lamp near anything flammable. A separate shelf
is preferable, as this will ensure the lamp operates
safely. CO2 is heavier than air, so it will drift
from the shelf down onto your plants. Do not place
the lamp on your reservoir if you are using a
||Don’t feed too
much wick into the glass casing. Only a minimal
amount is required for the lamp to work effectively.
If too much is fed through you will end up with
too much heat for the glass to handle and the
fame will be yellow and burn smokey, which you
do not want. You want to see a blue flame.
