Hi, I'm gonna brave the dark and try tray processing in PMK (Hutchings). The boo k ran out in the only place in Canada that seems to sell it, and the bottles cam e and leaked, burning out any instructions that may have been on bottle A are go ne. So, I have the dilutions, but does anyone know how long to tray process a sh eet of 125 FP4 in PMK -- can't seem to see an old thread and can't find a link t o the big development chart. Thanks Dean
