I have been fairly lucky for pests,,never take clones from anyone etc..but as a precaution and safety measure, I do sprinkle some DIATOMACEOUS EARTH on the floor of my tent before each grow, and clean and disinfect tent after/before each grow...you can also sprinkle abit on top of the soil if you'd like...it is safe for humans and pets alike, non toxic etc, and as they say, an once of prevention, beats a pound of cure...
