My experience exactly. I coat by window daylight, or fluorescent,
and our school lab was lit only by fluorescent... Wet emulsion *is* light
sensitive, but so much slower than dry it isn't going to fog -- as long as
you dry in the dark. However if you blow dry with *heat* IME that's a
marked variable, can often lower D-Max a LOT and/or fog or attenuate
tone.

A (small) regular room fan in the paper drying area will dry emulsion in
15 or 20 minutes without heat -- unless it has drips. But if you coat by
normal light, you shouldn't have drips.
