HOW TO AVOID PM:
1) Stop growing weed.
2) Eat a sandwich and relax.
PM thrives in the same environment as herb TG, so I dont agree with the environment theory, UNLESS you live in a remote area where PM does not exist yet on the surrounding flora. However, there are definitely things you can do to make your plant healthier, and less susceptible to the PM. Like inncoulate with bennies, to get the plant to start throwin down some SAR, add silicon to the diet, and burn sulfur to keep the spores from hanging with the ladies. All safer methods than spraying.
Also, there is nothing wrong with PM resistant strains. Who wouldn't want their favorite medicine to have that trait? Its one less worry, good environment or not.
And on that note, I am going to go spray a cannadential with some
eagle 20, because there was not enough ventilation in my veg canopy. Case in point TG. Not gonna risk losing another crop to PM ever again.
