i'm not sure, but i'll share with you my thoughts.

if you really paranoid, go in and quickly put them in zip locks, then go back in couple hours.

after reading a couple reports on Dichlorvus written by scientific types, i am not concerned for the plants.

as for myself, i put two in my bloom room yesterday, after a good watering.

i have about 1200 cu feet (12x12x8' ), and use a 480cfm exhaust with large canfan filter. i left the exhaust on, turned ascillating fan down, and left space immediately.

this morning, i went in for fast visit, wore a bandana on my face, didnt smell anything. returned to this forum, read all posts again, and decided that ill run all fans until saturday night, and ill turn off exhaust for 12 hours, then sunday, ill go in, put strips in zip locks, and do some close examining.

although my SM issue is very minor, i seem to have to DAILY wash, clean, spray, etcetcetc.,

i am hoping these strips save me alot of time and effort.

i must admit that there are 3 girls in there that are close to finish, and 5 in week 4 of bloom, so im taking a chance on my buddy's health with any taint that these strips MIGHT (mite) leave on cured product. but he has survived neem, pyrethrium, and azatrol, so i doubt this will hurt him.

i will NOT stop using neem in veggie state, and i will still spray them HEAVILY just b4 they are transplanted into 3 gallon pots, and sent to bloom.

good luck with your efforts, keep me posted.
