well using 24/0 is alright but if you want roots to set up properly you will need to give the crops a chance to photosynthesize. they can only photosynthesize in complete darkness. using 18/6 will give your crops a very healthy roots system:rastasmoke:

I am not an expert by any means, but I start 'em at 18/6 till they are ready for flowering room. Some folks start the seedlings at 24/0 for a few weeks, then switch to 18/6 but I'm of the opinion that everyone needs a nap at least once a day, lol. Works great for what and why I grow. (personal meds)
Half the closet is seedlings, other half is juveniles. This way, I don't have to worry about switching timers back and forth. (seperate flower room)

Actually, you need light for photosynthesis to occur.

...but why confuse the issue with simple facts, eh?

I've seen some major piss-fests break out over this subject...beware.

I like 20/4...use to be a 24/0 man.

But, I think Bob Bong said it best: growers choice, pick what best suits your needs as a grower.

i like 24/0, but for safety sakes i run at 20/4 so that the lights can cool down between 20 hour on periods.

18/6 is argued as more "natural" as it closer follows the sun's cycles.

Only dif. I've ever noticed was in my electric bill .
I normally use 18/6 - 20/4 so ballasts -n- blowers get a break -n- equipment lasts longer .

This may not help them last longer. Most electrical equipment is most prone to break when it is first powered on. Think about how many times a light bulb burns out when you switch it on versus how many times it just burns out after already being on.

I ran my first grow 24/0 because I didn't have a timer at the start, but I would go 18/6 -20/4 now that I have timers simply for the electricity cost.
