Ventilation
& Odor Extraction |
 |
| |
|
|
|
| In
order for fast growing plants adequate air circulation
and ventilation are essential. |
 |
| Indoors, fresh
air is one of if not the most over looked
factors contributing to a large harvest.
Fresh air is the least expensive element
that can be made available to your plants.
Experienced growers really understand the
importance of fresh air, they spend the
time and money setting up the best ventilation. |
| A
1.5-m x 1.5-m garden will use 20 - 40 litres
or more of water every week. Most of this
water (70%) is transpired (evaporated) into
the air. Every day and night, rapidly growing
plants transpire more and more moisture
into the air. If this moisture is left in
the grow room, humidity increases which
stifles stomata causing growth to screech
to a halt. High humidity opens the door
for pest and disease attacks. When you replace
moist stale air with fresh dry air, transpiration
will increase and plants begin to grow rapidly. |
|
|
| Airflow is the key
to temperature and humidity control. A well balanced
ventilation system, will act as climate control
for your grow room. Fan capacity as well as configuration,
will decide the effectiveness of any ventilation
system, a room in which the exhaust fan tries
to remove more air than can be replaced will labour
to control either temperature or humidity, air
removed must be balanced with air replaced to
maintain proper airflow. |
| Find the volume of
your room by multiplying the length, depth and
height. For example, a room which is 2 meters
long (2m) 1.5 meters deep (1m) and 2 meters high
(2m) 2m x 1.5m x 2m = 6 cubic meters (6m3) 1 cubic
meter equals 1,000 litres of air, so this room
contains 6,000 litres of air, in order to remove
the total volume of air in this room you will
need a fan with a capacity of at least 120 lps
(litres per second), hotter or more humid rooms
may require greater air exchange. |
| Any increase in any
area of your garden must be accompanied by an
increase in ventilation, if you add more light
you need to move that heat, if your plants grow
faster than previously you need to move the extra
moisture, effort spent on air circulation and
exchange will result in stronger faster growing
plants. |
How
to stop unwanted odours from escaping your room
is a question every gardener will tackle at
one time or another. . |
|
|
 |
| There have been
many methods of controlling odour, Masking
odours using citronella or other heavily
scented products, ion generators and Ozone
generators to name a few, each method has
pros and cons but none were 100% effective
without constant adjustment and supervision.
Then came Carbon filter canisters and the
solution seemed at hand, with no moving
parts and 100% filtration the carbon filter
has become the mainstay of any good garden,
but there are negatives. |
| Carbon canisters
are heavy often 10-20kg or more with cheap
shit, hanging one in your garden can prove
tricky. They are expensive to ship and damage
easily in transit, they are not easily modified,
once you buy a 150mm filter you must have
a 150mm fan and they are hard to dispose
of once depleted. None of these negative
aspects have stopped carbon canisters from
becoming the best option for your garden.
At least until innovation met inspiration
in the form of the Odorlok Sok. |
|
|
| The Odorlok Sok. A
carbon filter that folds flat, that is less than
2kg when packed but will give 100% odour protection
for 12 months! I shit you not. |
| Odorlok use a unique
tri-layer carbon matt system, the fibre is impregnated
with ground virgin activated carbon to give an
effective odour absorbing area 10x that of the
pelletized carbon granules you find in carbon
canisters. Just 1 cm square of tri-layer carbon
cloth will have the same contact area as a 1cm
square 10cm deep carbon canister. |
|
 |
| Tri-layer carbon
cloth will fold and roll small enough to
carry in one hand, simply using the enclosed
expanding rings to create a rigid structure
you can easily fit over your fan. Because
the Odorlok Sok is so light you can easily
hang it anywhere without the need for bulky
and unwieldy hooks and chains. |
| The
Odorlok Sok allows greater air flow and
results in much less pressure loss when
using centrifugal fans, the benefit in increase
airflow while maintaining 100% odour protection
is invaluable especially in the summer months
when increased temperatures require greater
air movement. |
|
You
won’t believe how light, compact
and effective they are until you try one
for yourself. |
