WLP 568 for a Belgian Saison

Got the starter cold crashing in the lager fermenter Chest for a brew day tomorrow…any thoughts on what temps for how long with this strain for best results? White labs says 70-80, but I’m thinking a few days at 68 would be better, then ramp it up each day after that until high 70’s are reached. I have the heater wrap and thermowell ready to run…
