Put Woodfordes Wherry with Hop tea on yesterday at 2pm, left overnight at 19 degrees +/- 1 deg (thermostat).
Just looked at it expecting to see big crusty head or at least some bubbles and nowt, I did get wherry given of someone who'd had it at uswanted gift so cant vouch for environment yeast has been in or duration, i do have spare in fridge.
