    Golden oldie answer here.From G.W.Crawley, BJP Jan 27 1961 p40-41,the time for Adox 14 in FX-2 is 12 min 68 F. The time is the same as for FX-1 and I found 12 min with 30s then 10s/min agitation OK for this.Efke 25 is sometimes considered a close descendant of Adox 14.

    Crawley mentions that dilution may be doubled or trebled to form stand developers acting over 1-2 hours at room temperature.

    He says this time may need individual adjustment.
