[RFI] Lighting grow cycle of Pot...

[Tom Thompson]

Dave,

 From what have observed, the lights are on continually for about two 
weeks and then a 12 hours on / 12  hours off until harvest which can 
take a number of months.  Depending on the setup, the lights are off for 
a week or so while a new crop is planted, and then the cycle repeats.  
To get the latest, just google cannabis grow cycle.  See:
