Yes, 12/12 is tried and true. "if it aint broke don't fix it" etc.
However in the name of science - One can ponder, research, experiment and discuss to tap into the differentiations, pros and cons with different light cycles
On this note i've scavenged this forum for most information but it's reasonably scattered/un answered - I'm also relatively new but regardless if any info here is incorrect by your knowledge or otherwise, by all means speak up and contribute to the thread!
Starting with 11 On/ 13 Off
*Dj Shorts Info - 11/13 is Better used for breeding on Sativas/phenos which prefer environmental conditions near the equator?/tropical conditions, for bringing out unique characteristics
*Studies -
*Copied, Cannabis is classified as a 'short day' plant as it is concerned with its photoperiods. There are: (short day) (long day) & (day neutral). Although we call them 'short day' plants it is somewhat of a misnomer. The day-light length has no effect on the flowering mechanisms of plants. We call them 'short day' plants, but they actually require a LONG NIGHT. The trigger for any and all plants that require a specific photoperiod is only the dark period. I have ran several trials on Cannabis to show this first hand. The typical axis point is 9-9.5 hours of dark, some cultivars (cv.) require more. the larger majority of cv. are well into a safe zone at 11 hours.
*Growmies experience/Forwarded Research - 11/13 can be used either in weeks 2-4 in attempts to negotiate those stubborn phenos/girls, or in the final weeks 8-9-10+ to speed up the flower cycle
Pros:
- Can bring out unique strain variables
- Can Speed up Flower Time
- Minus 1 hour per day of electricity i guess
Cons
- Reduced Yields
- Not guaranteed to benefit every pheno if im understood?
13 On 11 Off
More Light = More Bud
Less Dark = Longer Flower time
Honestly haven't found more on 13 on and 11 off as a general, more just a quick read on sativa dominants.
If anyone can add to this for my sake and others it would be great!
I do intend on experimenting as i go down the road and adding to this obviously, but if anyone has any experience i'd love to hear about it as well!
