..in my little grow area i have noticed a couple of what looks like gnats. they fly around land on a leaf then fly away . there is no "bug" damage on the leafs that i can see. i read the sub forum but i do not think these are spider mites............ideas , thoughts ??? history : i just brought them indoors from a 6 week veg state ...in the northeast had to start the flowering indoors. any idea what this gnat type bug is ? harmful? i wonder if it came inside when i brought the plants indoors........thanks !!!
