#1 Charcoal Filter/Fan Mistake
If you search on Youtube or even just do a general Google search on Charcoal Filter/Inline Fan Grow Tent Installation you will see 100% incorrect usage of the fan and filter.
Most all people purchase charcoal filters to alleviate the smell of growing cannabis. The need for this has certainly lessened especially with more and more states making recreational use and personal growing completely LEGAL. So the fear of getting busted is gone along with the need to get rid of the smell if it was for that reason.
Because their objective was odor control, everyone mounted their filters and fans ON THE INSIDE of the tent blowing OUT. This causes a huge problem, so much that I will not smoke anyone else’s weed that grows with a set up like this. Why? Because the bud is CONTAMINATED and potentially unhealthy, maybe even deadly to smoke. This is one of the main reasons I grow my own weed. I know my stuff is clean as can be.
What everyone fails to grasp is that by putting the filter and fan on the inside of your grow tent you have exactly replicated a shop vac on a much larger scale. Now your tent will be sucking in all the air around it which is filled with dust and every kind of industrial fiber known to man going right inside your tent with a motor running 24/7. And where is all this dust and contamination going? All over the worlds stickiest plants! Can we say DUH? Why does my name have to be so popular in this community?
The correct way is to mount the fan and filter on the OUTSIDE of the tent blowing PURE FILTERED AIR all over your weed. Make sense?
If you still need odor control you can mount another filter on the exhaust of the tent but only if you have a fan and filter set up outside first. I have converted 100% of the people I have shown this to in person. If you don’t think your weed is covered with junk, take a look at it under a microscope. Don’t compromise your health with potentially carcinogenic substances. It’s bad enough we’re smoking already so we don’t need to add deadly carpet fibers to our smoke for example.
Another method of odor control is to just have a fan and filter not even connected to the tent but just running open in the room as a room air filter only. Very effective but you still want the outside setup always for pure fresh airflow into your tent.
