I have a question about air circulation inside the curing chamber.
I recently picked up a True GDM-19 Commercial Cooler on craigslist and I am in the process of building it up as my curing chamber. I wanted people's advice on air circulation. I'm trying to get away with adding as little devices as possible inside the chamber. So I was wondering if i can utilize the fan that is already built inside the cooler.
A lot of folks i see use a fan inside their chamber but I noticed that this cooler when turned on has a great fan that sucks up through the top, across the cooling coils and blows back down through the back wall inside the cooler. it moves enough air that air is moving throughout the entire unit, while its turned on and running of course.
Under the control of my external temperature controller the chamber turns on i would say for 1 minute every 15 minutes or so. during this 1 minute the fan is blowing and circulating the air inside the chamber.
Doing some searching I see some folks say you need to circulate just a bit, some say you need to pipe in fresh air from the outside, (i want to avoid cutting the walls if i have to) and some say you just need a fan inside the chamber running constantly.
So if the internal fan circulates in 1 minute intervals every 15 min or so: Is this enough air movement to be considered decent circulation for dry curing?
