I am making an incubator out of a wine fridge. It isnt quite wide enough for 11" flexwatt, do you think I could do 4" or should I try heat cable instead? As far as a fan, exactly what do I need to hook up a fan. I am not entirely sure how to hook up a 12v fan to a 120v socket. What kind of transformer or converter do I need? Radio shack was no help what so over. Does anyone have links to the products to buy?
