Still finding a them here an there. Ive hit the plants from underneath with the sprayer on the hose like you suggested them gave them a blow out but i didn get the kill a mite i used the natures way crap once the plants dried out
View attachment 4503092 then hit them with eco neem week later. Its not exactly your method but as im skeptical on hittin them with anything apart from water at this stage i thought doin what i did was better then nothing. Next grow i will be more prepared an if i get mites early flower i will go about it with your method..
On the postive i found some asian lady bettles amongst the plants an from what i read they eat mites, aphids etc
