Wow i had a japanese snow tree cricket that loved my granddaddy purple. He was eating the leaves and chirping at night little bastard!
Took me weeks to catch his ass.
Those type of fellas may be harmful to your crop because of the environment they produce that is so attractive to them but just like spiders keep fly and other insect population under control naturally all these play a part in mother nature… If I had outdoor space I’d research the local bugs and maybe plant a small garden close by to detour them from your cannabis plants… Things like flies roaches mosquitoes and other disease carrying insects can burn lol
