Hi! its my first time attemping hibernation for my three collards. I have read multiple places about using a mini fridge for this. I recently purchased a 1.8 cubic foot mini fridge with adjustable thermostat. Does fresh air circulate so they wont suffocate. I was wondering if they will suffocate in there, or am i to leave it cracked. Im a little nervous to try it. Any comments of experience on the this is greatly appreciated. Thanks
