Figure 4.1 - This is a home made Ozone Generator.
Picture by Shipperke.In some indoor set-ups a fan can be used to
extract any unwanted smell away from the
corridor outside. It can be pumped through a
window or filter to another area where the
smell will not be noticed. Not only that but
plants love fresh air and wind, so the fan can
do two things at once for you. An Ozone
generator is a device that can be purchased
from most grow shops. It helps to get rid of
cannabis odour problems.
