ODORS AND NEGATIVE IONS - Weed Growing Guide
Negative ion generators have been used for years now to cut down on odors in
a grow room, but reports are coming in that a negative ion generator will
increase growth speed and yield. No true evidence to support this, however it
does make sense, due to the fact that people and animals seem to be altered in a
positive way by negative ions in the air, so plants may "feel" better
too. Try putting one in the grow room. You may notice the buds don not have as
much scent when picked, but that may be desirable in some cases.
A negative ion generator can be purchased for $15 to $100 depending on the
type and power involved. Some have reversed cycles that collect the dust to a
charged plate. It is also possible to use grounded aluminum foil on the wall and
shelf where the ionizer sits, to collect these particles. Just wipe the foil
clean once a month. It should be grounded to an electrical outlets ground wire.
If you don not cover the wall and shelf with paper or foil, the wall will turn
dark with dust taken from the air, and you will have to repaint that wall later.
