Every time I get a bag fungus knats fly out when I open the bag. Could be cause where I get it from but I'm finished with fox farm.
while you wait for the lime to activate and the soil to dry out, usually 2 wks... put the soil in a shed or closet and put a hot shot no pest strip... by the time the soil is ready to use all bugs will be gone..even mites. just my 2 cents
