Marijuana odor is the number one reason why cannabis crops become exposed. So when a noticeable marijuana odor can be detected in your neighborhood area and you hop into your jaguar convertible everyday high as a kite, people will quickly make the connection. There are always panicky or jealous neighbors that will gossip or alert the authorities when they suspect something. That’s why you don’t talk about it and the good news is that marijuana odor can be prevented. Here are the three most common things that cause marijuana odor to spread and tips on how to prevent it.
Cause 1: No vacuum space
Use a vent fan to extract air from the marijuana grow room. It is important to adjust the vent fan so a vacuum is created in your marijuana grow room or tent. This way you ensure that all the air can escape only through a filter. Test the vacuum by holding thread in the opening of the marijuana grow room or tent and hold the door only slightly open. If you have successfully created a vacuum, the thread will be sucked into the room. If there is no vacuum or if there is excess pressure, it’s possible unfiltered air seeps through holes and cracks. And this you will smell! Make sure there is enough ventilation.
The rules are: the amount of lamps x the amount of Watt divided by 2 = air outlet. And half of the outlet is necessary for inlet. So for 5 x 600 watt you need 1500m2 outlet and 750m2 inlet (5 x 600= 3000 divided by 2 = 1500m2 air inlet). Connect both vent fans to one controller. This way you can prevent activation of only the air inlet, causing excess pressure, due to temperatures measured in different areas of your marijuana growing area.
Cause 2: The wrong filter
With a vent fan that is too small you risk your cannabis crop being exposed. If you have a vent fan for 1500 m³, you must adjust a filter for 1500 m³. Even better is to adjust a filter with 20% more capacity than the vent fan. A filter contains active carbon that neutralizes negatively charged scent ions. When a filter is too small, the vent fan will pull air through too quickly so that the air isn’t filtered sufficiently. The carbon needs time to do its work. Use a filter no longer than one year. After this the carbon is ineffective. You can of course replace the carbon yourself, but keep in mind that this is done with professional equipment, like a vibrating plate, in factories to evenly spread the carbon. It would be wiser not to take any risks and buy a new one.
Cause 3: Leaking exhaust
A small leak is hard to detect, but can cause an extreme amount of marijuana odor. If your filter is attached to you vent fan with a hose, make sure it is secured with clamps. Inspect the hose for holes. Pay good attention to insulated tubes, because the inner aluminum tube contains little holes. It’s best to connect the inner tube to the flange first because this one attaches easily. Now attach the outer insulated part of the hose with a clamp and tape to the box. If you connect the filter directly to the flange of the cochlea, make sure you tape everything really secure into place. If you follow these rules your neighbors should never smell your cannabis crop.
