Saison fermentation box experiment

[Prionburger]

So I got a giant insulated foam dry-ice box from work, that I believe will hold two carboys.

I'm thinking of brewing 10 gallons of saison (perhaps a blend of 3724 and 3711), pitching them at 68-70, sealing the box and letting their temps ramp up on their own, maybe with a little help from a temperature controller and heating pad.

Will they ramp up too fast?

Anyone have any experience with this in a fridge or freezer or something similar?

Honestly no experience with a fridge, but i wouldn't worry about it ramping it up to much. I just did a saison and all the research i saw said that saison yeasts can ferment at 80-90 degrees! The higher it is, the funkier the beer. Good luck. I actually put a fermwrap on mine and turned it on without a temp control. Hopefully i can get it in the 80s or even 90s!
