Been vegging 24/0 for two years, explosive vegetative growth, along with most other commercial growers that i know. fuck the scientific stuff.
This appears to be the scientific arguement against a 24/0 light/dark cycle for veg

Yes, but the commercial growers that don't veg for 24/0 and also report explosive growth are potentially spending less on expenses per crop.
One thing this thread has made me realize is that there is absolutely no basis for consensus. Everyone reports explosive growth using their favorite regime.
And you don't realize that most if not all of the techniques that you and your buddies use are scientific in nature?
Yeah, Fuck science. Fuck it in the ear.
Experience comes before reports made by horticulturists studying how roses veg. Find a article where the study was done on marijuana plants and it will have more meaning.
The amount of money "saved" by a commercial grower by going from 24/0 to 18/6 is insignificant to say the least. When your power bill is $2,000 per month, saving $45 isn't really gonna persuade me to jump on that band wagon.
Many people might claim explosive growth but in my realm, where my grow is my entire income, trust me, if it wasn't workin' out I'd be on top of it ASAP.
So in that sense, yes, fuck science in the ear.

Ive always figured that 24/0 gives the most compact node spacing in general.
Its pretty simple when you think about it. When the plant has a 20/4 schedule it will be a bit lankyer because it is "looking for light" during the 4 hour dark veg times. Whereas a plant with 24/0 never looses that source of light and hence never hass to stretch for the light.

hmmm this is interesting....my flowering cab runs lights on at 2pm-2am...am i missing the best period of growth? how does a clone when midday is when it has been under 24/0 for generations? my light are on wierd time cos i stay up late and sleep late

I have not had that experience, but maybe it's because of propagating with CFLs that are kept ridiculously close to the plants.
However, when the lights are out, plants don't look for light, I think, unless there is a light leak teasing them. The stomata close and the plant hydrates through the roots.

Many people have done their own test and come to conclusions. I will do my own.
The 24/0 have many good points.
It's certainly possible that there is a sweet spot level of light (PPFD), humidity, temperate and CO2 that allows for a more constant level of photosynthesis, with few peaks and valleys, that requires no breaks.

this is a fascinating thread.
i've been vegging 24/0 for years with intense lighting and grow large, high yielding plants.
it is obvious that the "dark processes" occur in the presence of continuous light.
but, i too have recently read a thread here, that i'm having a hell of a time finding again, that showed weight and growth studies under different light regimes.
it clearly showed that 20/4 was the best overall producer and was given a rating of 100%.
the next best was 24/0 at something like 87%, followed by 18/6, which i can't remember the % for but i think was in the 70% range
i'm still looking for the article.
if anyone finds it please post the link. d9

Where do you guys come up this line? I love it.
I don't think you or anyone else that posted it to this thread really understand it what it means.
What's the difference between getting information from successful cannabis growers, borrowing from tried and true crop farming techniques or attaining information from controlled experiments conducted in laboratories?
Your telling us that not once in your lifetime you've learned from an experienced grower with refined techniques, be it talking to them directly or reading their grow journals? Is it your advice to newbies that they should ignore experienced and successful growers?
Are you afraid of Ogre calling you a nerd?
Is there a technique that you use in your garden that isn't based on something that fits this description?
I am good at identifying brains and talent in other people, i.e. identifying experts in their field and really don't care if they wear a lab coat or jeans to work.

And speaking of which, what have we here, what looks like an expert. A SCIENTIST!
Auto flowering I am still clueless about, totally fascinating shit.

I think the debate can be closed on AFs. Also still considering them a sub-topic for now, as in the results could be different for standard (?) cannabis.
The goal is to grow the most best pot in a safe and convenient way while trying to maximize time, effort, electricity, and safety. Now the conditions in nature are certainly a starting point, but obviously those parameters can be improved apon (co2 supplimentation, unnatural growing media, unnatural feeding schedules...ect.)
Im pretty sure that there isnt much difference in outcomes from 18/6 and 24/0 or whatever, and Im positive you can get good results with both.

Well its always been 24/0 for me and as for me, and possibly only me, this debate is done and over.
Thanx Mistress, luv the research and the quotes you do. Now my wife wants to find an outfit like that so she can play magician!?!?!? I think its the top hat she really likes...lol. Maybe I'm supposed to disappear or something.....and leave the garden???

I would be interested,too. Tagged.

The only difference it is to me is I have to plug the timer in for veg too, not too big of a deal.
Sorry I don't have that comparison, I think it was on another forum somewhere and I have no idea where to start looking. If anyone else has seen it maybe they can post it.
Hi Bounty, perhaps you were referring to a post on another forum by Oldtimer1? He tested veg light cycles on different sativas. The best veg light cycle for indicas and crosses might be different, however. Here are his findings...
Quote(Oldtimer):
We did a lot of experiments with light times a few years back using known sat and sat dom clone lines.
With Vegging ie under hid lights.
20/4 produced the most sturdy growth and the most bulk. Best final yield, taken as 100%.
22/2 Less of both. yield 88%
18/6 Studier than 22/2 but slightly less bulk. yield 87%
24/0 Much lighter in all aspects than 18/6. Yield 79%
16/8 The weediest plants. yield 67%
Plants vegged to final pots under fluorescents at 20w per sq ft on 18/6 yield 49%
Have not tried 36 hrs dark but did try 48 hrs from 18/6 veg. The final yield was down between 15 and 20% by var the pure sats the biggest loss in final weight and caused the odd herm, [sats] it did reduce the flowering time by 5 to 8 days.
For the mum lines we have 20/4 to 12/12 gives the best crop weight and bud quality, really thats all I’m interested in.

Well she knows that if I go the garden goes. She had her chance after I was laid up (car accident) for 8 weeks. The garden was still alive......sort-of. I figure thats the reason she's kept me around for almost 30 years. That and the occasional nice corset from "across the pond". So maybe the gas mask isn't for emergencies and the new collar isn't for the dog??? And where did my "Houdini" books go to??? What yard sell baby??? I don't remember any......oops...
Life may not be the party we wanted, but while we're here we might as well dance.
