Regarding pests, I realize that I sound like a know-it-all and I really don't mean to, I totally accept there are times when your crop is in peril and the gloves come off. This is people's lively hood in many cases and the stakes are too high.
Also, with gorilla, when you seldom get the chance to watch things properly, maybe there's a case for doing something preventative, but I'm not sure what would really work other than maintaining a healthy plant, choosing a sensible site, maybe some pruning. D.E. around your trunk can keep a lot of the crawling things away (though your worms won't like it) and a box of ladybugs. What sprays last long enough except hardcore toxins which seem totally against my concept of gardening? Those are saved for last resort, personally I'd rather lose a plant than poison my beneficials and soil.
Calico makes a lot of good points about growing weed in nature.
Certainly generations in grow rooms has bred some natural strength out of strains but selecting for resin ( which is one of the plants
principle forms of protection) should only be a help.
The bigger issues are plant structure (like how Diesels can't support themselves) and climate tolerance.
If I was gorilla growing I would want acclimatized seed.
Weed is such a sturdy and adaptable plant. It will grow wild in all kinds of conditions. If a plant makes it past seedling the chances are it will adapt.
Gardening is not a totally natural process whatever method you use.
If you plant and water crops you are setting up a mini ecosystem. If you plant in arid areas you are creating an oasis and a hotspot. At first things may get a little alarming especially if you've used a lot of organics (flies love shit). Soon however, the predators show up and a new balance is found. I found plenty of companion planting is important if there is no green in the area. Avoid monoculture syndrome.
What I am saying is based on what I read and personal experience. Others have done more of both and I am always looking to learn. So I dig the chat.
And don't tell me about grasshoppers. I once lost 30 olive saplings in 24 hours. They ate them to the ground despite sprays and even netting. Fucking nightmare.
When there is a plague there's nothing you can do.
Good luck.
