Some great ideas. I'd love to install a window AC in the basement tool room where my summer fermenation is happening, but it probably won't happen soon. For now, the mead is in a tub with 4 ice packs, the session IPA is in a secondary at ambient (ca. 70F), and the new hefeweizen is in another tub with an ice pack. Sounds like I should set up a fan and drape a t-shirt over the IPA at least. Southern New England gets moldy in the summer, though, so I'm a bit anxious about what could start growing on a wet t-shirt. I suppose I have enough shirts on hand to swap them out daily. Vacation starts in a week - just hope fermentation is quiet enough on all fronts by then and that ambient stays below about 70...
