Thats your prob always use clean dirt thats stored indoors and not at a nursery
or like walmart wich have there soil outside there soil is for gardens and flower beds outside ..go to grow store and get a bug bomb and spray in your tent to kill any critters before they dine on your buffet your serving them ...i dont like any bug sprays but before i grow in 1 of my tents i bug spray the whole tent that way its easier to deal with pests as they come and be ahead of the game ..i only spray bug spray initially when plants are still babies i wont spray a bug spray again as i dont want my buds full of pesticides..
