sounds abit like Bro Science - heard this claim a few times regarding Cannabis .
TREATING INFECTED PLANTS
So far, the incidence of this condition have not been proven - only reported - in cannabis plants. However, the news is not good if you suspect your plant has become infected. There is no cure. An infected plant will have TMV forever. Your main goal, in other words, is to find the infected plants and remove them from the grow. TMV appears to spread via contact. As viruses can also be present in pollen and seeds, they can live for a long time in a grow room. They can survive on grow room equipment, carpets, soil, and dead plant matter.
That is why it is also essential to immediately quarantine and remove any plant you suspect is infected, pronto. Be sure to fully sanitize all grow room surfaces of any TMV traces before starting your next grow cycle.
A NOTE ON PREVENTING INFECTION IF YOU SMOKE
If you smoke cannabis or tobacco, you run the risk of carrying the virus on your hands. As such, it is a good idea to always wash your hands before coming into contact with any plants.
