I can't really tell the exact temp on my SSV but when I exhale vapor clouds they are not visible in normal lighting. I have a really powerful light on my phone though that I use when I exhale, when I put it close to the vapor then I can see thick clouds. But when I take away the close powerful light and I'm in normal lighting I can't see the vapor at all, its practically invisible to the naked eye. My question is, am I combusting if I can see only see the vapor with a close powerful beam light? Or is it still vapor?
