Insects in pot are less intense. Growroom critters, such as aphids and spider mites, rarely damage marijuana after harvest. They completed this study at the request of the DEA agents, whose offices were overrun by the pests. Thankfully, the researchers found no cannabis equivalent to Lasioderma serricone , the tobacco cigarette beetle. Otherwise some whacked government lab would be growing the bugs en masse to spread across the continent.
Fungi destroy more bud than bacteria and insects combined.
Bacteria in marijuana may be more dangerous to humans, but they are rare. Some fungi won't rot pot, but they will put you in the hospital. Many fungi causing disease in plants die off after their host is harvested. After harvest, your competition becomes Aspergillus , Penicillium , Rhizopus , and Mucor , the baddest actors on the planet. Westendorp first found an Aspergillus species attacking Cannabis in 1854.
