i honestly feel dumb as hell for asking this but..

who says 24/0 is not good for ur plants? the FUCK?! my plants look HEALTHY as fuck and i went 24/0 for 3 weeks straight then switched to 18/6.. I even heard ppl using 24/0 throughout the whole vegging process & have not one single problem.. 2 EACH HIS OWN.

Mine run 24/0 and have since day 1. no adverse effects, however if you could provide links to discussions backing up your claim that it is bad I would enjoy reading them to get more perspective about the subject.

Sounds about right. I figure our girls probably need time to rest or sleep. If I remember correctly the roots do some stuff while the upper plant rests.

Not entirley sure and I'm to lazy to look it up right now, haha. Logic tells us all things that are alive must rest at a certain point.

24/0 might work, but they won't be doing better, it doesn't happen in their natural habitat and they grow plenty big enough in that. Stick to whats natural, I would bet the plants use the dark period for something throughout the lifecycle.

Also, I believe roots do the most growing while the rest of the plant sleeps

-I have zero true sources. But sounds right.

another dumb question -- what's the best initial lighting schedule for photoperiod plants? 18/6?

is there anything proven to work better than that?

Cannabis is a type of plant that needs no rest period...

Growing take patience because u must wait for your plant to literally grow...

I do 24/0 because i like maximizing the amount of time in veg...i hate waiting around...

Consider this, if you were to grow 2 plants that were identical except 18/6 and the other being 24/0
at the end of the month that 24/0 plant will have grown around 1/4 to a 1/3 faster than the other...
That my friend adds up...

And to all of you guys on here saying "the plant needs rest" or "well thats how it is in nature"
i feel that it totally your guys opinion and although i understand where u get your logic
from i feel that its wrong...

Just because something is not exactly as nature is does not mean that it is worse or better...Most times
i would say you would want to replicate nature but in some circumstances we can do better than her...

science and technology is badass...

If anyone has references or sources showing why or how a 24/0 is bad or that
a 18/6 is better for some reason i would love to see it...

Paging all scientists, lol.

Someone needs to get on this! Side by side 18/6 vs. 24/0

It's been done. Cannabis, as with most flowering plants don't need darkness to grow, they need it to flower. A plant under 24 hours of light will grow faster. It's that simple, that whole "your plants need rest" idea is stupid to say the least and has no factual evidence of such a claim. I've posted on this so much I really don't care to look for the information and post it AGAIN.

very stupid question but any way here we go lol.

so once i switch to 12/12 i immediately change out my bulbs to 2700k?

Everybody starts where you are, at the beginning.

Personally I would add the 2700k bulb and double your lighting output. This 24/0 versus 18/6 cycle can all be answered by using a Co2/oxygen detector. Take a reading during the light on then compare to the lights out reading. Very Different reading, now if you ask yourself why, and you should have your own answer. Arguing only show just how much you know and proving anything on sites like this is asking for someone to crap on you and your evidence. Due your own research and believe in your experience because they are what will tell you what's going on. I recommend 18/6 to all my growers and only one out of 15 runs a different schedule. Personally I have seen the difference, some strains stress more, some stress less, doesn't mean its all good.

None of that makes any sense.

A lot of jaded folk would yell at you and tell you to google it, however I am a firm believer of asking those I trust and I would say that a lot of people in this community are willing to help no matter what the question. Some just don't have the time to link you to the all the different sites with the information you need.

I like to keep my plants 24/0 , not sure if there is any real hardcore proof but my plants seemed to be taller when you give them time to sleep.

It's funny some folks wouldn't take the time to help you,though,they'll take the time and write to rip you a new one too funny....

i do 24/0 for veg...but i use t5 to veg.
ive also done 18/6 for veg, but found that they grew a bit faster, for me, on a 24/0 light cycle.

What you wouldn't add another light? Adding more lumens makes plenty of sense. You don't have access to a meter do you? you will see with a meter it makes perfect sense. Go rent a meter and have a look for yourself. Any safety supply store will have the units...they are expensive, probably why so much argument. JAS

agreed....

I used 14/10 for 30 days and the plants grew fast and indica's stayed short and thick while sativas hit 2'.

May never run 18-20 on again.

14 on / 10 off... Interesting. I would think you would get less fan leaves being less light.
