Well all you can do realy is wash and change b4 going into your grow room if you have been in the garden or a friends grow room b4 hand.
But they will somtimes come in through ventelation .
They are bastards ,once they r in they r in and i found nothing to cure an infested grow room, not even predators.

I spray vehicles for a living , so when my grow room is empty i fill my spray gun with bleach and water 50/50 and spray every square inch including lights and balasts which is very sucsesfull .
Tech Reviewed by Tech on . Spider mites Well I had to harvest a week early because of spider mite's. My grow room is 6 feet long 5 feet wide and 5 feet tall. I have no idea how my crop became infested. Now I have cleaned the room spotless. Is there any steps I can take to keep the lil bastards out of there? Plz help a newb in need. Rating: 5
