Yeah, it would help a lot to lst it some before hitting scrog net the otherwise it could get difficult to manage. I just keep my veg on a 24hr on light schedule and have no worry with timers on it. Autos will flower just fine with no darkness and photos will veg fine with no darkness. Of course running 18/6 or 20/4 won't hurt anything either. Save a few bucks on electricity and give the plants a bit of a rest
