If this problem is so common, and is nothing more than physical contact, why does it still exist? Killing invisible amounts of surface PM should be pretty simple. Are you telling me there's a preference to grow PM and spray buds at harvest? Because that's real common too. Or are pot farms really this braindead?
I would never buy clones. These braindead fraud breeders charging 15 bucks for bottom larfo branches with no starches or endophytes. Laughable this entire industry is throwing it's reputation in the trash over utter refusal to educate themselves. Monsanto will save us i guess. I'll buy cuts from them since no one else is qualified.
