I found that I had spider mites and I am in the process of douching the room. ( All plants are gone, walls bleached ) I just grabbed paper towel roll and found this lil dude on there, looks like a centipede? A coincidence or is this a common garden lurker?
If the roll of paper towel was in the grow room it's likely he was there for a spider mite snack.. If you want good grow karma let him outside since you're trying to kill his food supply. Don't squish it, it was helping you.
