which is better? 24/0 or 18/6 lights
A 6 hr dark period may not be enough to hold a plant in flower, usually it needs 8 hrs or so to stay in flower. With alot of strains tho they won't trigger flowering at 8 hrs, it may be necessary to start at 12 hrs of dark to get them to flower but you can then cut them back to 8 hrs or so after that.
While the plant does not have a clock per se, it takes a certian amount of time for certain hormones to increase or decrease, depending on light or dark duration. The plant's hormones act like switches, turning on or off certian processes such as when to go into flower mode. This is determined by the plant during the dark period.
You'll come across some recomendations of put your vegging plants into 24-36 hrs of darkeness before going to flower, this is to insure flowering and supposedly helps put the plant to flower quicker.
The photoperiod controls the rate of growth as you have seen yourself. In simple terms the more light, either intensity or duration will increase growth rates.
But everyone needs to keep in mind these are generalizations; with different strains and individual plants there will often be exceptions to general rules.
One big exception is landrace equitorial sativa's, they can veg very happily at 12/12, just because that is close to the photoperiod they are used to.
Photoperiod is one of the easiest ways to manipulate a plant and it's growth for our benefit. We are just scratching the the surface in understanding flowering btw.

I don't think you really need the 6 hours of darkness, considering you're watering the plants, giving them nutrients, and controlling the light & temp in the room. Most proponents of the 18/6 cycle will say that during the 18 hours of light, your plants are processing the light via photosynthesis and the 6 hours of darkness allow for root growth. Considering you're controlling the environment though, root growth isn't really a huge factor unless you're growing plants so huge that they could unroot themselves from being top heavy.

My first need to give negative rep, I can't believe the website actually thanked me. You are very welcome canna.com.
Excellent thread BTW, OldMac, I love the logical approach to things. Seems logic flies out the window when people see pictures of big buds in their head sometimes.
May bear stating that if you can't keep good light discipline in your veg spot that 24/0 may be your only option.

Yeah irydyum, that makes another good reason to use 24/0, falls under the enviromental issues catergory.
But I've said before the issue of 24/0 vs 18/6 or any other choice between, is a personal decision based on what works best for an individual in his or her own set up. I've used both for various reasons and now using 20/4 in one grow, just because I've got a few auto flowers in with my moms, and that was the recommendation as "best" by the seed producer. And the moms could care less (they told me).;)

*drags an old thread from the grave*
On the topic of light periods. Ive read that the best scientist is nature... Has anyone thought about what kind of effect it might have if the lights were "scaled" on and off? Like, turn a quarter of the light on at first, then slowly bring it to full lighting, like a sunrise? and vice versa obviously to introduce dark.
Maybe doing the change gradually would be easier on the plant or some such something.
Just food for thought. :jointsmile:
