Hydroponics does away with the
need for soil to grow plants in, thus allowing
indoor cultivation of plants. An essential
requirement for indoor green rooms and nurseries is
an efficient air filtration system to ensure that
the growing plants have access to adequate fresh
air. Carbon filters are ideal for this purpose.
Odor management is an important
issue associated with indoor vegetable production.
Vegetables, especially certain varieties such as
cabbage, have a distinctive pungent smell. This is
especially a problem with green rooms or nurseries
since the enclosed space does not allow free
circulation of air. Besides, the hot and humid
conditions inside the green house that are ideal for
plant growth, also promote the vigorous growth of
odor producing compounds like benzene. The result is
an overpowering smell in and around the area of the
green house or indoor nursery.
Charcoal carbon filtersare the best air
purifiers for use in hydroponic green houses. They
have activated carbon, which has absorbent qualities
that allow it to filter out even minute contaminants
in air. Activated carbon resembles a sponge with
holes of different diameters. When air is passed
through it, the pores filter the air by trapping and
absorbing molecules of contaminant compounds.
Charcoal carbon filters are usually hung on walls or
placed on the floor of the nursery.
These are some popular charcoal carbon filters used in hydroponics: IGS Goblin Filter: This is a lightweight
filter that weighs only about 10 pounds. It is especially suitable for use in
the Hydrohut Original & Deluxe models. It uses 100% virgin coconut charcoal.
This filter may need to be replaced every 6-8 months.
PHAT Hydro Filter: This is a popular little
filter. It is ideal for small spaces where the filter needs to be directly
attached to the exhaust fan. It uses virgin coconut charcoal.
Can 50 [420 CFM and 6" collar]: This
activated charcoal filter has a capacity of 420 CFM.
It comes with a 6-inch collar. It can purify large
volumes of air and is ideal for use in hydroponics
gardens. |
