good call guys. it was $6.96 at lowes.
do you guys just leave it in your grow rooms? I have an exhaust running 24/7 as well has fans to circulate air. can i store then in a tupperware container and just take them out like 1 day a week? or should I just leave it in the room? should i leave the exhaust running? i dont think shutting the exhaust off is a good idea, but ive heard i need to do this to let the toxins build up. should i just leave it off for a couple days to exterminate the current mite population? then turn it off for a day and night once a week? or just leave it running after that?
