I just built I new enclosure. And ralphie is whistling now. Is this a normal thing? I'm starting to think that I need an extra light because it's bigger? I got a 100w to get more heat. Is this too much? I'm no expert. But with the help of this site I always get it done. Please take a look at the pic and tell me what to do. Don't mind the tin foil. Waiting for the o the plexus glass to be cut. He also just hides now.
