Thanks, nn. Having used the Tetenal kits many years ago I now recall that it was one of the few that stated that dev temp could be reduced with a corresponding increase in time.
However when using a Jobo processor I always stuck to the 100 degrees Fahrenheit with 3 mins 15 secs as I had read from others more experienced than me that a lower temp wasn't ideal.
I never noticed streaking with the Jobo processor and the 1500 series of tanks but I recognise that there might be advantages in terms of control of temp by using lower temps unless you have a thermostatically controlled Jobo which the OP doesn't have.
I'd certainly be interested in the outcomes from anyone who has used a Tetenal kit at a lower temp.
