it takes more energy turning on cfls than it doesnt keeping them running 24/7 so if ur using cfls thats even more reason to use 24/0
24/24 better than 18/6?

Lights are only good for about 8000 to 10000 hours at most and expensive, if you want to replace them more often 24/0 is for you.
this is true regardless of veg/flower. and yeah plants grow the most during the dark, they are just taking in the light to use (but yes they grow a lil bit during the light still). id go with 18/6 ovr 24, just b/c ive read elsewhere many a time that plants can only absorb 18hrs of light a day.I can tell you now that it will be successful, there is no doubt about that. But until you compare the two cycles you won't know for sure if one is faster than the other. I have also heard that plants experience the most growth during the dark period. but that might be during flowering

you didnt read much of this post obviously if you think energy costs are the reason to not run 24/7.

I personally know plants grow at night. My plants are on 12/12 now but even at 18/6, when i checked my plants in the morning, i know what has grown due to the fact that the new growth is much lighter in color, because it has not been exposed to a full day of light. If you dont believe me, check your plants as soon as the lights come on, and you will see.
This is a complete mis-statement. It in no way takes my 42w CFL bulb more power to run less hours. Lightbulbs run on a kilowatt/hour system and I garantee a light running for 8 less hours a day is going to use less power and last longer than 24/0.
Incase nobody noticed. CFL's last for YEARS. Give the buggers a break every once in a while.

very nice post Seed, where is the 18hours of light? and is this a proven test? just wondering, good information tho

I'm sure 18/6 has little change 16/8 is just easier to manage on my sleep schedual until I get a light timer.

If you're talking about guides that you have found on the internet, then the answer is yes. I'd take scientific fact over some stoner's grow guide. I read many of these guides, which is why I started a 24 hour cycle on my first grow. If you are talking about actual published grow guides that you can buy on like amazon.com etc., then please give me some names so I can look them up.

I believe Garden Knowm uses 20/4 light cycle for vegging... correct me if im wrong tho.

interesting topic, we were taught in my Bio major class in my senior years that plant grow manly in night-times, using up O2 and the sugar and TPA they build up during the day-times... so 24/24 would be good maybe in the weeks after the first grow and before the flowering is started, so the plant can stockpile on TPA and sugars, giving the plants a lunch bag for flowering huge...

that is a common myst that is not true, it doesn't take more energy to start up a cfl than to fire up a conventional bulb and this is done in a nanosecond anyway
so you can chill about using up to much energy by firing up cfls
(it is true that every start cuts into the total lifespan of an cfl by the way, so that is a fact
)

I do 18/6 for vegging with CO2 at 1,500 PPM during lights-on only for soil indoor grows.
Anything past 18 hours is wasted electricity by all my reads and experiments.
Plants need the lights off cycle to do their thing otherwise it is not natural and beneficial.
I use soil with mycorrizhae innoculants and have a CO2 monitor/controller hooked up to a solenoid and timer to deliver optimal conditions for growth.
After monkeying around with every freaking set up and light schedules, I veg 18/6 until desired height, then flip the switches to 12/12 and until trichromes start to get cloudy and I then harvest.
