The trick with outdoors is to have a huge variety of different plants. Then dont use any poison anywhere. As all the bugs move in the ecosystem reaches an equilibrium.
And bugs are a lot less fond of Cannabis than you think but obviously they wont hesitate to go bos on your canna plants if they have nothing else to eat.
I probably have a billion spider mites in the garden, but they are on everything except my cannabis.
Outdoors, planting any pumpkin or melon just for the sake of having the plant and not necessarily for its fruit is far preferred by spider mites.
Check out the pics below. My one plant is a meter away from the jelly melon.
On the melon leaves are thousands of mites and mite carcasses. The carcasses tell me the predatory bugs are at work. If I now spray the melon and kill all the mites, then the predators will leave and search for food elsewhere. Once the balance is messed with pest epidemics usually follow.
On the weed leaf. Negligable for a plant that has been outdoors since September.
