I think I am in the safe zone now but I just want to double check.
I cannot afford to buy a matstat at the moment so I went with one of these:
it only cost 1.50 Euro and after playing around I have managed to get the temp stable at 31 - 32.2 C
This is registered by a digital thermometer and the probe is taped to the glass floor of the viv, directly above the heat mat and under the substrate.
As near as I can tell this temp should be safe but it is in the high end of the safe zone.
even a small adjustment on the dimmer causes it to drop all the way down to 22c so I must be very close to the lower limit of the dimmer.
