Hey not much of a pro but im on my first grow aswell n im about 4 weeks till harvest so im thrilled, as for temperature i havent had a problem with it, but as long as you dont have it to cold(65) n below or to hot(85) n up you should be fine n yea you can grow in roomtemperature wich is around 70-75 just make sure to wacth out for temperature drops or rises like at nigth when it gets colder n at day when it gets hot, so i advise having ligths on at nigth to counter the cold n off during day
