I haven’t heard of it but I appreciate the recommendation! I use a handful of things to try to control the pests, i like to rotate through them so maybe this is one i should add. I have had great luck with @JohnnyPotseed solution (https://overgrow.com/t/mites-thrips-aphids-one-n-done-with-pics/).
I have a question for all your experts out there… I want to spray some of my flowering babies with Johnny’s and the like. But I never spray those inside… today it is currently like 30F degrees outside this morning with a high in the 50s. Do I need to worry about hurting the plants if I take them out into the cold and cover them in cool liquid and then rinse them. Rinsing isn’t needed but I like to get all the dead bugs off. I am guessing nothing bad will happen to the plants for such a short visit outside but doused in cold water and outside? I can bring them inside to dry so they won’t need to be out there too long.
