- Q. What is the most effective
way to eliminate my grow room odors?
A. Charcoal filters are
very efficient in removing unwanted odors. They remove 99% of all grow room
odor when used correctly. Nothing on the market can compete with a high
quality charcoal filter for grow room odor removal.
- Q. Do ozone generators work for
odor removal?
A. Yes. Not nearly as
effective as a charcoal filter but they do work to some degree. They do kill
bacteria and fungi very well.
- Q. Is ozone harmful to humans?
A. High levels of ozone can
burn your skin and really hurt your eyes. Do not stare directly at the lamp
in an ozone generator. If you can smell a strong ozone presence in your room,
that means you are using too much. Ozone will oxidize the cells in your
lungs and can be hazardous to your health.
- Q. How exactly does ozone work?
A. Ozone is 03. Oxygen is
02. Ozone is oxygen with a third atom stuck to it. It does not like having a
third atom stuck to it, and it will do anything to get rid of it. After about
1/2 an hour the third atom falls off, looking to grab a partner. In this case
fungi and bacteria are usually that partner. Once the 03 has shaken its
third atom, it becomes stable again and can move on. Ozone works best when it
has a chance to mix or swirl with its particles.
- Q. How does an ozone generator
actually make ozone?
A. Ozone lamps (germicidal)
produce high energy photons that hit oxygen gas and expand the electrons, and
a third oxygen atom comes together to form O3 (ozone). Germicidal lamps are
powered by special ballast and come in a variety of different sizes to fit
specific grow room requirements.
- Q. How long does the average
charcoal filter last?
A. That depends on the
manufacturer. High quality filters such as Can filters or PHAT filters will
last from 2- 3 years of continuous use. They can be repacked, but its really
not worth it. These filters are
professionally manufactured for long lasting unsurpassed duality, while the
average Joe at home cant possibly pack the carbon properly. After 3 years of
use you should feel no worries about replacing it.
- Q. Is it good to use oscillating
fans?
A. Yes, lots of air
movement is essential for a productive indoor garden. Oscillating fans push
the air through the leaves and the tops of the plants, which is where good
air flow is a must. Leaves take in the air on their underside through tiny
microscopic pores, known as the stomata. Oscillating fans help keep a
constant supply of air movement within the plants, which really helps the
plant replenish itself with fresh air.
- Q. When should I use C02
in my grow room? Day or Night cycle?
A. C02 is only needed when
the lights are on. During the plants dark cycle the plants actually respire
Co2 and breathe in oxygen, just as human do.
- Q. What's the best way to
produce C02 for my indoor garden?
A. There are
two very good
options. The first option being propane or natural gas C02 burners, the
second being C02 tanks
used with a regulator and solenoid hooked up to a timer. The propane and gas
burners produce high amounts of heat, but are definitely more efficient cost
wise to operate compared to the cylinders. Propane is easily available at
local gas stations, while Co2 cylinder usually have to be purchased at a welding shop.
Some hydro stores carry them for lease. If the room is large, then the
propane or gas burner is much more efficient. If heat is a serious problem,
then the cylinders definitely have an advantage. They produce no heat,
but can get costly to operate on a large scale. The burners have been known
to cause high humidity in the room, so growers will have to really keep an
eye on humidity when using a burner.
- Q. Is C02 really that important
to my garden?
A. Yes It is. Growers on
average report a 20-30% increase in their yields when using C02 properly. C02
is what your plant breathes and requires for photosynthesis. It is truly
amazing how well your garden will do when adding Co2. It is truly the best
thing you can add to your garden to really get it growing in high gear. I
cannot say enough good things about it. It is expensive to set up, but once
you're going look out because it's going to get out of hand! Save your money
from expensive additives and supplements and invest in a C02 system and you
will be seriously impressed. I can sit here all day and tell you how great
it is, but you have to see it to believe it.
- Q. What is the optimal
temperature for my grow room?
A. Optimal grow room
temperature would be between 75F - 85 F. After that photosynthesis starts to slow
down because the stomata (leaves microscopic pores which breathe in air)
close down to conserve water transpiration.
- Q. What should the root zone
temperature be at for optimal growth?
A. The
ideal temperature
your roots will be most productive is 75 F (23.9 c)
- Q. What is the purpose of
adding C02 to my grow room?
A. C02 plays a major role
in photosynthesis. The leaves produce sugars by using light to combine water
and nutrients with C02. When you increase the rate of photosynthesis with
C02, you increase the growth rate, and the potential yield from your plants will
increase.
- Q. What is more efficient to
operate, an inline fan or a squirrel cage fan?
A. Based on CFM per
amperage, inline fans are usually most efficient. They have been designed
with maximum air flow at a minimum wattage, leaving the grower with a very
efficient product. Squirrel cages are becoming a thing of the past now with
the evolution of inline fans taking over the market. They deliver so much
more CFM per watt than the typical blower that it only makes sense to invest in
an inline fan.
- Q. What is a quieter fan to
operate? A squirrel cage fan or an inline fan?
A. Inline fans are
extremely quiet and usually much more efficient than the squirrel cage fan.
They typically have a higher CFM rating per watt than a squirrel cage fan
and usually come with a 5 year warranty so it's hard to beat them!
- Q. What should the humidity be
at in my grow room?
A. Ideally,
the humidity should sit between 55-65%. Any higher than 70% can pose a serious problem.
High humidity in the dark cycle can lead to gray mold and can ruin a crop.
Humidity is very important and should be maintained with a hygrometer. These
are inexpensive and really help. When the humidity reaches a high level a
dehumidifier is a must. These can be purchased at Home depot or Wal-Mart and
they work excellent. Dehumidifiers can easily pull 5 gallons of water a day
out of the air, so keep an eye on your humidity levels.
- Q. I have an 800 CFM
fan exhausting out. What CFM fan should I have bringing fresh air in to supplement
the air going out?
A. You
should always bring in at least 1/2 the amount of CFM into the grow area as
you are exhausting out of the grow room. Constant fresh air is a true asset
to any indoor garden and is definately needed for optimal growth.
- Q. How many CFM should I have
for every 1000 watt lamp in my garden?
A. A safe recommendation is
125 CFM per 1000 watt lamp in the summer. This should rise to 150 CFM per
1000 watt lamp in the winter. Excess heat can really slow production down.
- Q. Is it possible to use a
standard window air conditioner in my basement grow room?
A. Yes this is very easily
done. It is very simple and works so well. First measure the dimensions of
the rear of the unit. Call a heating and ducting company and have them
fabricate you a box. Most ducting companies will do custom fabrication for
very reasonable prices. Have them construct you a box 2 feet deep with a 4
inch round duct at the end. Have the box built so it fits perfectly over the
rear of your window AC unit. The idea of the box is trap the heat produced
from the rear of the unit. Once you have a fabricated steel box, fasten it
with self tapping screws to the AC unit. Attach a 4" inline fan to the 4"
duct on your box to suck the heat from the AC unit. Vent the 4" duct out a
dryer duct or through the furnace to remove the heat the AC unit produces.
It may seem like a lot but it is a simple procedure and it will really
reduce the heat in your grow room. I had a box made for $45 and it worked
like a charm.
- Q. What type of ducting is
better to use, aluminum flexible or the vinyl flexible?
A. Use the aluminum. It
will retain the heat better than the vinyl. Aluminum ducting is not much more
expensive than the vinyl and is a much
better purchase in the long run.
- Q. What are the Stomata?
A.
Stomata are tiny
microscopic pores on the leaves undersides that control the flow of air into
the plant. Basically, its the Nostril of the plant. It is important to keep
plants free of dust and dirt as it can clog these tiny pores. High humidity
also affects the stomata by reducing its ability to respire.
- Q. What should the temperature
be
in my cuttings area?
A. The room temperature
should be between 72F-75F for maximum rooting.
- Q. What precautions should I
take with a Co2 burner? I've heard they can be dangerous?
A. C02 burners are safe
when used correctly. The first precaution is to purchase a carbon monoxide
detector. Theses are very cheap (around $ 40) and will let you know if your
home reaches high levels of carbon monoxide. Co2 burners should be purchased
based on grow room size, and therefore should be safe to operate. Make sure
your burner is mounted securely. Remember this is a fire hazard due to the
fact there are flames burning at all times. Make sure nothing is in the way
of the unit and that it is secure and will not tip over. Test for leaks using
soapy water at all fittings at least once a month. When used properly, C02
burners are great. They do, however, require some care and are not for the
average Joe who is just playing around.
- Q. What is Dry Ice?
A. Dry ice is C02 that has
been frozen and compressed into blocks. As it melts, it turns from solid into
gas, releasing C02 into the air. Unfortunately, it is hard to store and can
get expensive to use.
- Q. What is better for a carbon
filter? A Can Filter or ODORSOK ?
A. With Carbon filters you
are getting what you pay for. Can Filters will last alot longer tha,n an
ODORSOK but cost alot more. ODORSOK's work excellent but will not last
as long as the CanFilter. If you are on a tight budget and need a quick
reliable fix to odor problems, than the ODORSOK is a great choice.
- Q. CAN FILTERS - How do I
install a Flange?
A. You can purchase a
flange separate from your filter and fan, or have it come with everything in
a Box Combo. Take the foam tape gasket and apply
it to the outer edges of the flange, then simply center the flange on the
filter and attach 6 screws in a star pattern.
- Q. CAN FILTERS-How much CFM
lost through the filter?
A.
Each CAN Filter size provides a different resistance to each style and size
of fan you attach to it. A filter at the maximum exhaust CFM rating has
approximately 0.7 wg. pressure drop. All Fans will have a lower CFM at a
higher pressure. For example, at .5"wg The 10" Max-Fan goes from 1019 CFM to
885 CFM. The 12" Max-Fan would go from 1708 CFM to 1595 CFM.
- Q. CAN-FILTERS- Do I need to
replace the pre-filter?
A. It is a good idea to
replace the pre-filter when they become dirty because the pre filter is
blocking larger dirt and dust particles from getting into the pore structure
of the carbon. A dirty pre-filter increases the pressure, which will
decrease the flow through the filter.
- Q. CAN-FILTERS - Can my Filter
be refilled?
A. Technically the filter
can be re-filled, but it is not a good idea to self-fill the filters at all.
The reason for this is that Can-Filters uses an industrial shaker with timed
intervals and a dust extraction system to ensure a packed carbon bed .This
eliminates the possibility of preferred air channels through the filter,
because as we all know, air does not wait in line to go through a filter, it
finds the path of least resistance and crowds in. So if you tried packing
the filter yourself, as soon as you got it as full as you think you could
get it, attached a fan and turned it on, the fan would vibrate the carbon,
and over time the carbon would settle and you would be left with air gaps
all over the place.
- Q. CAN-FILTERS - What is the
Maximum Temperature/Humidity I can run my filter at?
A. The maximum recommended
temperature that you can run your filter at is 80 Degrees Centigrade, and as
soon as your start rising above 70% humidity, the water molecules in the air
start to get stuck in the carbon pore structure and slowly diminish the life
of the filter.
- Q. CAN-FILTERS - How long does
the filter last?
A. The life of a filter is
determined by the concentration of the contaminant, the relative humidity
and the volume of air cleaned. Unfortunately there is no indicator light on
the filter that tells you when it is ready to be replaced. Experience with
one Can-Filter will give you an expectation for future Can-Filters in your
particular application.
- Q. CAN-FILTERS - What is the
Can-Filters packed bed design?
A. During the manufacturing
process, Can-Filters uses an industrial shaker to vibrate the filter to ensure
the carbon bed is packed tight and full to the top. This process eliminates
any preferential channels which would allow the odor to pass through the
carbon without the proper contact time. Canfilters only uses quality
activated carbon that is designed for your manufacturing processes. The CFG
packed bed design filter ensures the highest quality odor control.
- Q. CAN-FILTERS- Is there a
calculation for sizing a room?
A. Yes there is, and it’s
really quite simple. All you need to do is take your cubic feet of the room
(Length x Width x Height) and divide that number by the number of minutes
you would like to exchange the air in the room (Only 1 – 3 Minutes is
recommended), and that will give you the recommended minimum CFM that you
need for that room. Take that Min CFM number and match it to one of
our filters. As long as that Minimum recommended CFM is higher then the
exhaust minimum on the filter, you will have adequate airflow and proper
filtration for that room.
- Q. CAN-FILTERS- Are your fans
Speed Controllable?
A. Yes,
both the Can-Fan
and the Max-Fan line of fans are 100% speed controllable. Try the Can-Trol
Speed Control for your 120V fans. This control provides absolutely no motor
hum when controlling the fan, it also gives you the option to control the
voltage entering your fan. With an easy to use dial, you can go from 1v to
130V with a turn of your hand, no matter what voltage you run, your fan will
not hum!
- Q. CAN-FILTERS- Is it best to push or
pull air through the filter?
A. You
can pull
through the filter or push air through the filter. If you are going to push
air through the filter, it is recommended that you take off the outer pre-filter
and place it before the intake of the fan so you can remove dust and dirt
particulate before it enters your fan and filter.
- Q. CAN-FILTERS- Can you push or
pull through the filter?
A. You can both pull
through the filter or push air through the filter, if you are going to push
air through the filter it is recommended to take off the outer pre-filter
and place it before the intake of the fan so you can remove dust and dirt
particulate before it enters your fan and filter.
- Q. CAN-FILTERS- How do I size
the proper fan to a filter?
A. We actually put the
recommended fan size right of the sticker on the Can-Filter to take away any of
the guess work you may have. The same formula for sizing a room works to
size a fan to a filter and a filter to a room (LxWxH).
