This subject is plenty complex and believe me far beyond the scope of just a video on YouTube and as more States and even countries such as Canada continue to change and adopt new laws regarding cannabis production this issue has been seriously looked at and you wouldn't believe how far this is going and how much it matters moving forward. Oregon for one example has passed laws you can not have ever sprayed a cannabis plant with a pesticide or a fungicide in its entire lifetime, on top of laws like that you have to pass mold tests which I've heard and read 80% of mold failures didn't even show signs of mold on the bud. One of the two only companies allowed to grow in Canada is taking it seriously enough they built a cannabis production place, which they call the Space Station. Commercial cannabis growers are already seeing this as the way its going to completely wipe out every closet grower out there, and a large portion of the black market cannabis.
First commercial growers have to produce a better product, and now they are in the fight to produce it cheaper and better, with new laws such as no mold, no pesticides, no fungicides ever used on the plant, people are going to be faced with a cheaper better quality at reasonable prices, cheaper than you can grow it and thus the issue gets wiped out.
When you talk trying to reach people about mold, you are asking the guy with a couple of plants to toss out his whole crop and have nothing to smoke or something to smoke. You are dealing with people still asking "which lighting is the best?" and not even controlling their humidity, etc... and suddenly you want them to take something as serious as not smoking moldy cannabis and get them to think they can't grow their own bud any way they want, they need to filter the air, control the temps, humidity, etc... to prevent moldy bud. If you want to reach people you have to do it with prevention and nobody cares about that, because they just want to grow cheap bud and when you try to tell them things outside of that nobody wants to hear you.
To prove the point pick up any good quality book written on cannabis growing, and it will discuss lights, nutrients, CO2, humidity, temps, and everything else you need to know to grow the best bud, and it will dial in specific numbers. I bought a High Yield Cannabis book once, because it was suppose to tell you everything you ever needed to know to grow the biggest and best buds ever... I read it from cover to cover comparing it to my basic cannabis growing books... and everything, and I mean everything was the same, the temps, humidity levels for when, light colors, etc... I was so pissed, because no matter how you want to argue it, you always have the basics and from there only minor tweaks to your growing area to get perfect bud every time, and yet seriously who listens to that and how many times do you repeat the same things to the same people time after time?
