I was talking to someone in a PM and explaining some things about 24/0 vs. 12-1(GLR) and this is the first time I've been able to fully put my thoughts onto paper so well, so I'm gonna copy/paste it here for all to see, and hopefully understand why GLR works so damn well for vegetative growth and preparation for flower. Please note that IT IT NOT HEALTHY FOR LONG-TERM MOTHER MAINTENANCE! That amount of flowering hormone constantly built up in a mothered plant, eventually leads to total necrosis, and loss of the entire plant altogether.
Message follows:
Autos benefit from every amount of light you can give them. They don't even seem to have a "rest period" like their non-ruderalis cousins. So 24/0 would seem to be best for them. However, for the photo-type plants, they *DO* have, and need a rest period. It is most healthy for the plant to be in darkness when the rest period begins. Thus the more darkness you can give them the better. With the GLR schedule, the plant gets 11 hours with which to go into and out of their rest period in darkness. Even if the light comes on during this 4-hour period, it doesn't seem to harm the plant in the least.
To better explain what I'm talking about, I will say this:
Plants have normal Day/Night processes that they perform... when the Sun is up, they devote most of that time to photosynthesis, converting radiant energy from the Sun into chemical energy for storage within the plants tissues... Now, when the Sun goes down, they can use all that stored energy, to grow new cells both above and below the soil, and make repairs to any damage they have received. It is best not to have light on the leaves to detract from this process, because when this happens, growth can slow, and repairs are made much slower, because the day process can start up, or in the case of 24/0, never cease, and plants are not the best multi-taskers in this respect. Now, after the night process is complete, the plant will go into a rest period. This can be observed as a partial wilting, or drooping of the leaves, and usually happens on a 24 hour cycle. Light on the leaves can cause this rest period to be cut short, or not exist at all.
In humans this is known as sleep deprivation. For one day, or two, it's not all that harmful, but the human can be moody, and somewhat lethargic. Over a week, lack of sleep can start to cause physiological, and mental changes that are more serious. Delirium, psychosis, and hallucinations have been observed as effects in the mind. What happens in the body can be deadly as organs start to shut down. Kidney and liver function are first affected, and you know what happens when those two organs shut down.
Plants, while not as complex, and lacking a brain and organs of an animal, do have their own organs, and still suffer from lack of their rest period. Given an extended period of time, although in plants it's much longer, they will start to show more, and more serious effects of lack of darkness for their rest period. Some studies have even shown a complete cessation of growth, and even death of the plant altogether after a long period of time. It just gives out and shuts down.
Now, the good news is that it takes about 1.5 to 2 hours to shift from night process and/or rest period into the day process. The 1 hour of light in the middle of the dark period is not enough to rouse the plant into day operations, but it is enough to break the flower cycle by destroying the hormone responsible. This gives the plant 12 hours for day process, and 12 hours for night process, and for the rest period. This results in a much more healthy plant, and we all know a healthy plant is a rapidly growing plant.
