One of the keys to preventing pests from invading your grow room is keeping it clean. You should always clean your grow room between grows as well as while your grow is in process.
BROWNDIRTWARRIOR is an expert grower who gives advice on this subject. He says that a clean grow room equals a bug-free grow room. Also, you should keep floors dry to avoid electrical problems. You should also clean your tools such as measuring equipment, probes, and grow pots.
