24/24 better than 18/6?

Now for my regualr non mommies Im going to run lights 24 hrs from first day of clone for about 4 weeks then to 18/6 for a week to 10 days then 12/12 til harvest.

Why would you change to 18/6 before 12/12?

Thank you... some facts

any time bro...i think that info would make for a good sticky in grow FAQ

because 18/6 (in my case 16/ simulates the long days of summer. they flower at 12/12 because thats the day time hours of fall.

Yes, I understand that bro (not that extreme of a newbie anymore ). I was asking filthyfetch, why he switches from 24 hours to 18/6 for like a week and then to 12/12. I heard people say they do this to kinda gradually make the transition to 12/12. But I hear its absolutely pointless. I was just wondering if he did it for another beneficial reason.

i veg for 24 hours, and i continue to give my plants 24 hours of light all the way till flowering, i beg the differ about the plants needing sleep durring veg, why not speed up plant growth instead of givin them 6 hours of darkness in which they dont need. id much rather give them 1/4th more time under the lights with +1/4th amount of growth compared to 18 hour light period. my first grow i used 18/6 and id say i needed an extra 2 weeks before flowering compared to the 24 hour light period which saved me time.

did you read Seedlessone's post on page two? That is scientific fact. Would you rather have two weeks less in veg, or higher yield? Also, something to consider is the relationship between the extra time with lights on and extra growth, might not be linear. Meaning the extra 1/3 of light probably doesn't cause the plants to grow 1/3 faster. I definitely did not see nearly that much of a difference when I grew identical strains under both light conditions. Not to say there wasn't a difference, but I would have noticed a 33% difference.

Folks read the facts...there is more root growth at 18/6.

the name of the game isnt root growth for me. Personally, I'd rather meet 1/2 way from 16/8 and 24/0 to something like 20/4+. That way the roots don't use up nutrients the leaves would normally, and therefore bigger buds.

I posted this on another thread, but its relevant info:

all I've ever read was "most professionals use 24/0 lighting for optimum growth", which is fine if your growing clones and don't mind tall plants. However, I was talking to the guy that owns the local smoke shop here and he said when growing from seed, the amount of light the plant recieves largely determines its sex. I had my plants on 24/0 for the first week and a half or so before i found this out, then over the course of 7days brought it down to 18/6. He said the more light they recieve the greater the likelihood of them being male are. I haven't found ANY reliable information to support this, but I definatly changed my cycle to 18/6 until flowering.
Thoughts?

you say tom-A-toe, I say Tom-auto. I use 18/6, and yes you should care about root growth. More roots = healthier plants = more buds = pack it again = more high.

Right on, finally someone has sense.


Lando: If you think roots arent important you will never get the big buds without hydroponics. Soil growers should know that the more roots the larger the nutrient super highway. Oh and overall plant stability. Plant will be healthier and grow faster (provided you trim or give those roots space.

thanks seedless, i was going to paste that same comment, as it is what made me change to 18/6 as well.

regardless of that, 18/6 IS the way to supercharge growth. more/better roots = faster easier growth, access to more nutrients, etc.

this is even more true for those clones just starting to root! they need all the help they can get, and 18/6 gives them just that, i noticed a very great difference in my clones when lights were 18/6 as opposed to 24/0. the faster they root, the faster they start growing.

anyone who says "im not in this for the roots" isnt very educated, you see simple logic tells you, no roots = no plant. so you are totally in this for the roots. unless you just don't care about the quality of herb... or yield.. roots are the heart and soul here, you must care about them.

And the movement begins.

sorry I am by no means trying to come across as educated in the subject, im completely new to growing. I'm just repeating what I've seen in video's and/or read. Your right, I think the bit I heard about small roots = more energy to leaves was done hydroponically as opposed to soil. I am definatly running a soil mixture at the moment. I'm going to use 20/4 until i flower I think.

I personally do the 24 hour to 18/6 to gradually breing the plants life cycle into 12/12 since i run 24 hour so long to lessen the stress .Different heat temps different nutrient intake different environmet.Its a personal choice I picked up from long time friend growers and has worked well for me and do the ways I was shown has eliminated ever getting stress induce hermies.

A lot of us are here to grow better, correct? Then when studies have been done to show one way is BETTER than the other, why go agianst it? But ne way im glad to see the thread has stirred some interest.

peace~

Its an important tip becaise a lot of people dry out their plants and or burn them.

every grow guide ive read says leave the lights on seedlings for 24/0...but now i read 18/6.. are u saying the grow guides are wrong and u guys are right?

Most the books I read say after 18/6 your are justing wasting electrcity. I just posted the facts from a study. Look at the facts and make your own opinion on what you think is right. Good luck homie.

Well I just did a quick study on photosynthesis, and I would have to say, 24/24 for the first month or so would be good, then to 18/6 after, then flower at 12/12

The growth during night, I would doubt either, But arnt the roots what do the main growing? And they dont get any light what so ever...

But I Could be wrong... idk

whoa thats exactly how i'm doing it, i didn't do it on purpose or anything, it was just how it worked out i'm a lucky s.o.b. i guess. but yeah my plants have done really well so far, it did seem they grew slightly faster under 24 but i think the 24 hr stressed them too much.they just seem "happier" now on 18/6.
