They don't like Mint

I have Coffee Grounds I'm keeping for Compost.

I started drinking Mint in my Coffee so there is Mint in the Grounds. No more Gnats.

I'm trying to grow some Mint to put in my Tent.

I have some essential oil humidifier thing. I was running peppermint through it recently and was thinking that this “mint fogger” if put in the grow room might help pest problems. God willing I will never have a chance to test this but I will post results if I need to.
