I have the Brinsea Mini Advance and it has a setting for periodic incubation cooling. It is recommended in the instructions to start the cooling option after day 7 and stop on day 18. It also recommends to have cooling 2 hours a day during that time. And the cooling starts at the same time each day. I can set the setting to range 60 minutes of cooling to 360 minutes of cooling each day. Should I do this cooling option? If yes, how much time a day? Has anyone had any luck/bad luck with this setting?? Thanks!
