Awesome! I did not know this.Plants use mechanical energy from wind to produce electricity, we discovered this recently and still don't know exactly why...
As someone who can taste and feel fabric softener oils at 15 feet away, (from double fabric softener clothes) I almost completely disagree with this statement. There's a massive difference in quality between most indoor/outdoor cannabis and HEPA filtered cannabis. Granted, there are a few areas where nature has very little bear and mouse dander, dried bird feces, bark and leaf bits and other debris in the air. You should see all the stuff you find in 'clean' rocky mountain air. lol As far as I'm aware, none of it tastes great when burned and it definitely does not contribute to a clean off-white ash....and plants don't get covered from dust so easily, even outdoor.
I don't use ac, but go w/ 3 exchanges a minute. Several years ago I ran into power mildew. A filtered intake has been a blessing for me.
Have not (knock on wood) had anymore random infestation since I added the filtration.
Was left wondering how often spider mites etc ride in on a fly, moth etc.
My statement is also an observation designed to spark awareness. Those who have grown with and without HEPA will tell you the same thing about quality differences I am. The down side is only a small percent of the population of growers use filtered air.Douglas it was not against any of your statement or of anybody else...it's just an observation. Living plants have some mechanism to get rid of dust more then simple rain, not like a simple rock or a piece of metal. My 2cents are that it has something to do with static electricity or some other forms...and it doesn't mean an HEPA filter is a bad thing at all
Yes, as is my input on the subject. If you're growing indoor, yes you want a lot of ventilation, and you'll want it to be filtered air.the topic here is about ventilation in a vegetative setup.
