can you put hydrogen peroxide in the nute solution and then seal the tent to fill it with co2 to kill the mites?
iv delt with mites too, and pretty much ruined a whole perpetual set up. early chop and girls getting ready didnt survive the neem and hydrogen treatments.
i was checking a bud for ripe progress with a 30x and i saw a tiny little string, at first i though mold. then another string. and then i saw it, a mite crawling around. it was webbing.
idk how i missed it. i started checking all the leaves and they where everywhere. i didnt even notice. must have taken them only a week to spread. neem seems to work tho. leaves still have eggs and dead ones but just dead bodies, having seen a live one since. now i use neem regularly.
