Spending ages setting up your grow room or grow tent, only to find that
it emits a loud, constant shuddering noise
can be frustrating. But fear not! Whether you're growing in a tent or a room, here are a few easy tips to reduce the noise and keep your cannabis grow subtle and stealthy.
Are grow tent fans noisy?
The Main Causes Of Noise
The job of the inline fan is to suck air from the charcoal filter through to the fan, then to remove the air outside of the tent.
The actual fans themselves, when plugged in, can be very loud and almost sound as if an industrial vacuum cleaner had been switched on
.
How can I make my grow tent fan quieter?
Do you need a fan in a small grow tent?
Setting up oscillating fans will help moderate the temperature and humidity in your grow room, but fans alone are not enough.
You need an air extractor fan system to keep the air in your grow room or grow tent fresh
.
How do you quiet a duct?
What can you do? Short of
covering all your ducts with fiberglass insulation, or opening them up and inserting acoustic duct liners
, the best you can hope for is a modest reduction in the noise. Use rubber pads to isolate ducts from wood.
Can you make a fan quieter?
Here's how to make a fan quieter:
You make a fan quieter by placing it on a soft, level surface, reducing the speed, cleaning the fan regularly, or using sound suppressors
. You can also move the fan farther away from you. For inline duct fans, you can purchase or build an acoustic box.
Should I leave my fan on when lights are off?
When lights are no more on plants, no more heat is generated. And the photosynthesis process takes a break. However, plants keep breathing and leaving vapors around the leaves. So,
oscillating fans still need to be on duty
.
Does a sealed grow room need fresh air?
The concept of a sealed room is quite basic; a sealed room is a growing environment where there are no holes or air exchanges to the outdoors or any other room.
It doesn't need to be airtight
, however, the closer to airtight the better.
How do you ventilate a grow room?
To calculate the CFM you need to properly ventilate your grow space, use the following formula:
(Grow Space Width X Length X Height) / 5 = Recommended CFM
. CFM performance of a fan is affected by the length and path of ducting. If you are using a carbon filter, this will further reduce your fan performance.
Is it normal for ductwork to make noise?
Possible Causes of Ductwork Noise
The most common reasons to hear noise in your HVAC ducts include:
Air Pressure
: A buildup of pressure can cause rumbling sounds. It can also cause the metal to expand and contract. When the system comes on, air pushes against the walls of ducts, expanding them.
Why is my air vent so loud?
Vents can make loud whooshing noises if
the supply air ducts are too narrow
. Debris can also block the ducts or cause one or more vents to close. You can use a flashlight to see if the vents look too dirty. However, you'll need to reach out to an HVAC contractor if the noise persists.
What fan blade is quietest?
All Valent condensing fans have
serrated-edge blades
, which are up to 12 dB quieter than paddle fan blades. Inspired by the owl's powerful but quiet flight, Valent's fan manufacturer designed fan blades that mimic an owl's wing. Their fan's serrated-edge blades are significantly quieter than paddle fan blades.
Why is my table fan so loud?
A problem common to both types of fans is excessive noise.
Accumulated dirt can cause noise because it can unbalance fan blades and wear out bearings
. After every two weeks of use, vacuum a fan with a crevice-cleaning attachment. At least twice during the summer, wipe dirt from the blades with a damp sponge.
Why does my fan make a lot of noise?
A ceiling fan making grinding noise may be caused by
unbalanced blades
that cause the fan to wobble. Ceiling fan blades can become unbalanced by dust collecting on the blades when the fan isn't in use. Clean the blades by wiping them down with a damp rag to remove any dust and debris causing them to be unbalanced.
What is a passive intake grow room?
A passive intake is
an opening in the wall of your growroom or tent that is designed specifically to let fresh air pass into the garden
. These systems work through your inline fan exhaust system as it pulls fresh air from outside, while expelling stale air.
How do you circulate air in a grow tent?
How often should air be exchanged in grow room?
Air in your grow area should be exchanged
at least every 5 minutes
. If you are using a grow tent that is 5′ x 5′ x 6′ this is 150 sq/ft of air. For optimal airflow, you need a filter and fan that can move between 30 and 60 cubic feet per minute (CFM). It is also important to balance the flow in and out of air.
Do grow tents keep the smell in?
Simply put:
no, grow tents are not enough to block odors
. The materials and pieces that make up a grow tent system (reflective mylar, tent canvas, inline duct fan, ducting tubes, etc.) do not qualify as smell proof.
How do you cool a sealed grow room?
Air conditioning
is the perfect method to cool a sealed grow room. It maintains the temperature automatically once you set the required temperature. There are commercial as well as mini air conditioning systems available according to the needs.
When should I add CO2 to my grow room?
When adding CO2 to your grow room, the flowering stage is the most important. Adding CO2 to your grow room, especially
in the first 2-3 weeks of flowering
, can kick start flower production and boost flower size significantly.
