In my darkroom, I have (at the moment) only cold water. The water temperature is appr. 12.5 Celsius (54.5 Fahrenheit).

When using liquid emulsion (Foma), I am aware, the the temperature of the water, when washing the paper must must not be too warm in order to avoid bubbles in the emulsion. However - is there a problem, using too cold water when rinsing? In my case, I would like to use running tap water - but is 12.5 Celsius too cold? And in case it is not, I assume, that the paper should wash a little longer?
