When I give my room a good clean down, I keep the exhaust fan running and within 2 hours there is no odor of bleach or other cleaners. I figure that if I cannot smell it, my plants will be okay.
Yep. Couple hours. As long as you turned on ventilation. I have not bleached down my room in 5 cycles. Yikes ): prob should. Just shows as long as you keep it sterile and are on point for both mites and PM, you can go along time with no worries.
