Hey bro, some people say those pest strips are dangerous, but that's only if you're in the room for hours and if you have pets in there, which I'm sure you don't have pets in your grow room lol, anyhow, just use 1 pest strip and put it in your grow room and it works magic, it releases an odorless, toxic gas which is harmless to your plant, but deadly to pests. I love the pest strips, they work sooo much magic...
