To successfully grow cannabis in a tent, you need to install an exhaust system that regularly exchanges stale air for fresh air. If possible, you should try to exhaust your grow tent to
outside of your house
. Novice growers sometimes fall into the trap of venting grow tents directly into living areas, such as bedrooms.
Should the exhaust fan be at the top or bottom of the tent?
In this case, you may set the fan and/or filter outside of your grow tent.
We recommend setting your extraction fan at the highest point possible
. Since heat rises to the top, exhausting that hot air at that point will make the ventilation process efficient.
How do you install a exhaust fan in a grow tent?
How often should I exhaust my grow room?
Ideally, your extractor fan system should replace the air in your grow room
every minute, or at least every three to five minutes
. This means that you need to choose the right size fan for the job.
How long should you run exhaust fan in grow tent?
You need to keep the fans running
during the light hours
. This will help prevent humidity and heat affect your yield. During the dark hours, keep the fan off after 1 hour. Let the plant flower without any disturbance.
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
.
Where should I put my oscillating fan in my grow room?
Do you need intake and exhaust for grow tent?
Larger grow tents can benefit from using passive air intake as well but will require higher CFM exhaust fans
. Air intake is only a part of the indoor growing equation. Many factors like grow tent size, grow lights, and inline fans contribute to creating the optimal growing environment.
Where does the oscillating fan go in a grow tent?
Point your air circulators towards a wall or ceiling
Just hang it in the center of a square tent (use multiples in larger areas). If you have any other fan, be very careful to place the fan on the floor and blow air upwards, to ensure the temperatures at the top and bottom of your growing area are more even.
How do you set up an exhaust fan?
How do you vent a grow tent with LED lights?
Where should I put my inline duct fan?
For maximum performance and minimum noise, the best location to install your In-Line Duct FanTM is
6 – 10 feet from the register you wish to boost air to
. To prevent air leaks use a good quality duct tape to seal seams in the ductwork after installing the In-Line Duct FanTM.
How much fan do I need for a grow room?
To determine the extractor fan size of your grow room or tent, the formula is to multiply grow room volume(cubic feet), carbon filter factor(+25%), insulation factor(±20%), ducting(+10% for 10 feet) and the light factor(+10% for 1000W). You’ll get the fan size in CFM.
How should a grow tent be set up?
- Step 1 – Assemble Your Tools.
- Step 3 – Unbox The Rest Of The Grow Tent Package.
- Step 4 – Determine Ventilation Setup.
- Step 5 – Prepare The Carbon Filter.
- Step 6 – Hang The Lighting System.
- Step 7 – Install The Light/Fan Timer.
How much airflow does a grow tent need?
For a grow tent of this size, you’ll want to pick an exhaust fan with
at least 40 CFM
. As a general room of thumb, we recommend picking a fan with a CFM equal to the volume of your tent/room. This will ensure your fan completely replaces the air in your grow space every minute.
What causes high humidity in grow tent?
The air will hold more water vapor when the temperature in your grow tent is higher.
Heat in a grow tent causes the water to move faster through the air
, resulting in higher humidity.
Do fans help plants grow?
A fan can be of great help to any plant that is planted indoors as it circulates the air and prevents the dampness on plants and condensation
. You can use floor fan, ceiling fan or oscillating fan as per the requirement. A Tip: Do not position the fan directly on plants.
How hot is too hot for a grow room?
If you are growing marijuana in a grow room, keep in mind, the maximum temperature for marijuana grow tent success is
85°F
. Temperatures higher than this will result in the plant’s death.
Can I vent my grow tent inside?
For the majority of grow tent growers,
a passive intake system works perfectly
. Passive systems will actually not use an intake system. Instead, the inline exhaust fan will suck the air out of your tent creating a vacuum. This pulls in fresh air from the intake ports at the bottom of your tent.
Can you hang a fan upside down?
Things to keep in mind though is there isn’t any hook or anything to hang it but
you could probably mount via the inside of the fan or similar
. Also, you most likely won’t be able to have it on rotation but all in all it does seem possible if you can rig it up.
Do you need fresh air in a sealed grow room?
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 set up an extraction in a grow tent?
- First, place the carbon filter cover over the filter.
- Next, set up your hanging ratchets or straps in your Grow Tent so you can easily slide your filter in later.
- Then grab a ducting clip and place it over the opening of the filter.
