Thanks for the tip I will incorporate one after I purchase the rest of the nutes I would like to add to my regiment. For now I was lucky my bathroom has a 3-way for the light and the exhaust fan switch was in the two gang with the switch leg for the 3-way, so a junction with a pig tail problem solved. Also I noticed since I switched over to 12/12 the humidity level spikes in the 70% range during the dark period to fix this I put my tent exhaust fan(it cools the light too) on a separate timer from the light and run it the 12 hour on cycle then 15 minutes per hour during the dark.
