Thanks Weezard, I love the dryer sheet idea! I grow outside in containers too and earlier this year I saw the beginnings of spider mites (my second grow ever). My first grow, I wrestled with those suckers for about a month before I discovered Neem oil. This year I sprayed with Neem twice, three days apart and six weeks later I haven't seen a hint of one. I will use dryer sheets anyway because an ounce of protection means more ounces in the future! And I wouldn't be afraid of poison on the bud like with Neem. I'm only afraid it would trap moisture and lead to gray mold (another problem on my first grow I'm trying to avoid this time). There is a lot of humidity outside here especially in late summer when the buds are so vulnerable, so I've been spraying Serenade weekly as a preventative. So do you cover all the surface soil of the pot with the sheets or leave some open space?
