Our winters here aren't comparable to what folks have out west and up north.... We had a freak snow on November 1st... at 38 degrees! No one predicted it! Woke up and it was snowing like crazy, and by the night time, it was gone! lol But I'm not thrilled about the cold either, I'm a Florida...
If I'm not mistaken, the starter will run up to 10 nozzles? So if you just have the one cham, it's more than enough. Get the starter kit and go with that, if you feel that you need more nozzles, order more. LLL Reptile will save you in shipping costs versus buying it directly.
