Position the fans snugly inside the hole you cut and it must be in front of the box’s interior. 

For alternative ventilation, you can attach an exhaust fan large in size placed at the back portion of the refrigerator box. You can drill a hole in the lower portion of the exhaust fan for additional ventilation. The hole must be a similar size to the fan.

It must not be positioned directly facing a window as it can experience overheating and controlling the heat might be tough. Ideally, you can place it in the basement or garage. 

Once the growing finishes, the refrigerator grow box must be cleaned again thoroughly before starting new cultivation. There will be some cases that pests and parasites may crawl and could infect the next cannabis crops. It could also damage the construction of the whole refrigerator box if got worse.
