I quickly went to a swamp cooler. I got a large Sterilite bin, Cut holes in the top for the neck of my Better bottles. In the dark without coats from the second batch.
No I ferment in a temperature controlled chest freezer. I assume it is dark inside.
I have the back section of my cellar curtained off with blackout drapes. When it's too cold I have another closet that's a few degrees warmer. Guess that's not that creative, but it works.
