here in oregon the pesticide LOQ for piperonyl butoxide is <2 and we’ve been consistantly testing at around .4 which is a pass. but what this means is that extractors will not buy trim and larf as that .4 will turn into a 4 after extraction which is a fail for them.
i cannot for the life of me figure out where i’m getting this substance.
not using aerosols
not using pyrethrins
only using grandevo and nukem as pesticide/fungicides.
room clean with zerotol
could it be in my water? nutrients?
i’ve called marone, flying skull and royal gold to ask if there is any chance it’s in their products.
anyone have any thoughts as to where i’m picking this stuff up?
