Veg: 24/0 or 18/6?

[Delta 9]

G'day R.H.G. and welcome to the site

 

I'm only an amateur grower, but was stuck in the same predicament as you. Too many options, too many opinions. So I'm doing them all for myself. Last one was a 12-1 grow. Now I'm doing a 24/0 grow (with a mix of solar and CFL). So far, so good. I can't compare plants, because they're two different strains, only growing method.

 

When you find out the perfect solution, let me know

Any idea how important it is to keep the photo-period strict? I haven't got a timer yet and I've just been switching the lights on/off at around 18/6. Maybe +- 1.5 hours overall. Then there was a day I couldn't get home so had a full 24 hour thrown in there. Probably not very good... Is this likely to stress the plant much or should she be cool with it?

 

This is an autoflower by the way

if ya only half an hour off either side of a schedule, it should be fine....its like a cloudy day vs a pristine day....if that makes sense

providing they`re not having major fluctuations...like 18/6 for a few days and then 15/9...they should stay in veg and not stress to hermi......

 

if they`re on 24/7 or 20/4 for a length of time and then drop to 18/6, it could stress them into bloom or cause em to turn hermi when flipped to 12/12.....especially if the strain isnt climatised

 

end of the day, a good timer is worth its weight in gold, and vegging 24/7 works well for the lazy gardener

 

 

have fun with it

May I suggest find a grow diary that appeals and follow it. New methods are great to try, once you have a grow or 2 under your belt.

Hermies can be attributed to a number of things first and foremost genetics.

Alright. My 2c. Aaaaaagain.

 

Mr. Goddard.

You have not heard of the 12/1 theory, as it is STUPID. Light Equals Buds. Remember that. The more light you give a plant, the more buds it can produce.

 

Giving a plant 50% less light (or whatever 12/1 is) is not going to result in the plant yeilding the same as it would with regular light practices.

 

NOW. I've heard E-fucking-nuff about 12/1 and it's associated growers and their theories.

 

Vrod and D9. I believe there are a few 12/1 theory threads on here - may I suggest you just go in one of them and prattle to each other about how good and smart you are?

 

Noone else is interested.

Speak for yourself, AJ. Get out of your dungeon, live a little.

 

As for different threads, maybe you should take your own advice

Advice everyone needs to follow........

 

 

The title of this thread's topic is "Veg: 24/0 or 18/6?" not "let's all argue over a method unproven as yet"

 

 

V-Rod is keen to be seen as a "pioneer" with 12-1 veg timing but what he is passing of as a tried n true method is in reality just another grower experimenting......who knows maybe he is first to think about experimenting

 

My advice is stick to what you said in post #8 Goddard........."Personally I'll probably go with 18/6 to start with for the lower costs, then at some point after I'm fairly confident I know what I'm doing I'll probably make 2 completely identical setups and test it my self"

 

 

Peace MongyMan

the answer would lie in what kinda plants you want as the outcome .... plants need dark period sometimes to assist in stretch if plants are very bushy and so forth, it would depend on what strains you hyave, your grow environment etc ..... how old they were or whatever ..... plants will vege slightly faster @ 24/0 yet may not be obviously noticeable to begin with .... because of the lack fo stretch of the plants when theyre in 24/0 ..... (so the plants may possibly appear smaller in some instances) .... I always start my plants under a hid lamp @ 24/0 ..... decrease back to 18/6 after a week or 2 ..... if theyre not to sativa-like.... I like small short lil bushes @ 3 or 4 internodes in height and still short ... so i start at 24/0 and cut back to encourage vert growth (at that stage the plants have been hacked away and supercropped atleast once etc) .... i guess it depends on your desires ....

 

peace n pot ..

They're interesting papers though I'd be careful about applying them to cannabis as the physiology plants can differ greatl

 

 

 

cheers for teh reply, RH

I wondered If growing under 18/6 would be better for a plant that is know to be less stable. I was interested in what they had to say about the hormones released during the dark cycle can help reduce a plants stress reducing the occurance of Hermis?

Be great to do this study on weed

i just think if newbies are just starting out that they should use 18/6 and 12/12 and get that under there belts before thinking bout other lighting schedules my 2 cents

[BigG]

My stance on this would be

 

from personal experience and not scientificly researched reasons

 

18/6 will give a plant more stretch longer internode space

 

20/4 will give a slightly shorter bushier plant shorter internodes

 

24/0 will give a short bushy plant short internodes

 

so i conclude the dark period doesn't seem to give "growth" but "stretch" i think this is why its interpreted that cannabis grows in a dark period in my opinion it doesn't grow as such it stretches if this makes sense.

 

what does it mean in growing terms?

 

i would tend to use 24/0 with maybe a 250ww where penetration is not as great creating a shorter plant giving the light better chance to penetrate

 

20/4 with a 400w where penatration is slighty better

 

18/6 with 600w/1000w > where penatration isnt such an issue

 

i may also chose to taylor this to a smaller grow space or for use with a mother plant
