    White green stuff on carboy walls

    Racked a rye pale ale last night (controlled fermentation chamber and cold crashed 3 days) and found this stuff behind on the carboy and attached to the auto siphon. I can't find any other example like this stuff. Btw...smelled 'ok' but dry hopped at 4 days with Mosaic/Amarillo so may have...
