Botrytis has nothing to do with moths and caterpillars.
totally disagree, caterpillar poop is the best medium and catalyst to get botyritis, but you can definitely get it without caterpillars, based on density of buds, susceptibility of strain, moisture levels, health, etc. Mrs. Weedstein should grow a sativa-based strain like ghost train haze or Lemon haze, regularly use neem and sodium bicarbonate-water mix until flower, then use neem-cake tea mixed with lots of water and sodium bicarbonate (or baking soda) to spray down the buds and make a basic PH level that mold hates, the neem tea is mold resistant and so are sativas as they have open bud structure. And get a giant fan, and never turn it off even outside under a hoop house. Or grow in pots that can be moved indoors each evening as morning dew and humidity happens even under plastic.
