Hi, im building a grow box out of a old metal wardobe closet. I painted the enterior flat white. I got 8 42 watt cfls and have a system to hang them close to the plants. Im almost ready to begin except for the ventaltion of this wardrobe. I have some mother plants I would like to start cloning from. They been sitting near a window for a couple of months with the rest of my house plants. All my house plants have ultra tiny silver bugs in the soil, if I blow on the dirt I can see them run around. They are smaller than red spider mites. Will they be a problem ?
