[quote=salmayo]Given that you want the equivalent of 12 hours SID, we can subtract out your actual SID time of 6 hours, so you only need the equivalent (AD) of 6 more SID hours. So, if you are making the spectrum fit the schedule, you'd need an AD spectrum with a Time Factor of arround 8/6 (AD/SID needed in hours), = 1.333. Photoperiodically/Photomorphogenically a larger AD time factor will give you veg results, while an equal AD time factor gives you optimul flowering, and a smaller AD time factor will induce ceasence (and then death) (from too long a night).[QUOTE]

How did we flower with an (AD) time factor of 11/2 ? ......With alot less blue or no..
