I use a 12 quart Sterilite filled halfway with Zoo Med Eco Earth(40-60%moisture). I drilled fourteen 1/4" holes on top and ten on sides. You'll want to move the coir around a couple times a week for proper aeration. Temp range for Red Wigglers is 55-77 degrees. Mist once a week moderately. The breeding cycle is 27 days. Population can double in 60 days.
