I started going organic with my soil about 5 years ago. Not just with cannabis but the whole garden. There's no synthetic fertilizer anywhere in my gardens. Compost, worm poo, bunny poo, and I mulch with dead leaves. The garden yields great veggies n flowers year after year.
Last few seasons I have cut back more n more on bug killing sprays and started relying more on predatory insects such as Ladybug and green lacewing. I am down to homemade Dawn/vinegar spray to kill the lanternfly.
There are 2 insects that bother my cannabis here in NYC...leafhopper and the whitefly. The leafhopper aren't in great numbers and catching a few jumping spiders and putting them on my plants takes care of them. The whitefly are a different story. I get big swarms of them and they love many of my plants including cannabis. Need oil did very little so this year I introduced encarsia formosa at the first sign of whitefly. What difference! The whitefly are virtually gone from all my plants.
If you have whitefly issues and don't want to smoke need oil, encarsia formosa!
