I want to build a fermentation fridge so I can properly control the fermentation. The only problem I have is space constraints. There's no real space for me to put another fridge in the house. I know it wouldn't be too expensive to do, it's just finding somewhere to put it. I have a stout on at the minute and the place where it is fluctuates in temperature, it's gone off like a rocket for the first two days and now it's started to slow down. I'm just worry that it's slowed because of the temperature but it's not freezing cold, I'd say the room fluctuates between 16-20c. But, the instructions say to check the gravity after 4-6 days. The airlock hardly bubbles but I know that doesn't mean anything because I can tell it's still fermenting as the bucket has expanded.
