Someone said "Swamp Cooler Fermentation" so I thought I'd give another option :-)
Not speaking out against it - so many people use it with success, its a great option - just takes some practice to get it right and you're still limited through the hot months.
Just saying - if you're eyeing a new kettle, mash tun, pump, etc. etc. etc., invest it in good temp control (and a beer fridge to boot!) first.
