24 hr VEG? or 18 hr VEG?

[Aeroguerilla]

24hours the sun dont sleep so neither do my vegging plants

 

[Resistance]

24 hrs. for me. I'd rather have piece of mind, then a flowering plant from something simple as a broken timer. It's also easier to get temps dialed...and the plants like that. If paying for an additional 6hrs of light is a stretch in the wallet, growing dope probably isn't a good hobby.

We go with 24 hours since we used to run an NL that had some autoflower tendancies. Under 18 hours she would start to put out flowers, really stunting her growth in veg and making her ridiculously hard to clone.

Wait you ran autos or they had tendancies of being autos? And if you ran autos, how easily are they to clone?! I didnt know you could clone from em

No he's saying some strains are more photosensitive then others. Cloning an AF plant is useless in many, many ways.

I've put 100's of clones outdoors after 24hr veg/rooting. It sucks. They always waste time and energy between flowering and revegging instead of just growing like I'd like. I think it was mentioned, after they root, try turning back the timers to get them used to a different light cycle.

Being efficient isn't stretching your wallet.

A broken timer is either a rare instance or a dumb user who isn't 100% on top of their game, which at that point, I would say growing isn't a good hobby for them.

Sure its easier to dial in your temps, but you are also paying more to maintain those temps and it should not be that huge of a change between on/off to cause issues in veg... again if so, not grower material.

So first you say to go 24 hours. Then you complain about how it sucks when you throw the plants outside because they need to adapt.

Please review the information you share.

You contradict yourself and are not helping our friend here choose which they prefer/need.

I go 20-4 for the majority, then 18-6 for about 2 weeks, 16-8 for about 1 week, then right into 12-12 no 24hr dark period (I skip the 14-10)...then I finish the last 48 hours all dark. If the plants are big enough I do the 16-8 in the veg room, if flower chamber is free then I will do the 16-8 in there sometimes for 7-10 days until they get bigger.

I remember reading that photosynthesis of the cannabis plant greatly diminishes after 16 hours. I Veg'd under 16/8 this round, nothing started going into flower all whilly nilly. When I came across that little gem of information I was reading a lot on duirnal periods. Really I would like to do a 16/4 veg and a 16/12 flower and see how that goes.

Thanks...I was just about to start a shit storm with the "unenlightened"

With my 24 hour plants, i felt that they grew steadily but sluggishly.

Every time i look at my 18 hour plants right when the lights come on, it always appears to me that they experienced a noticeable burst of growth during the dark period.

Once a thread goes bad it doesn't get better too quick I've learned. Tryin to keep the peace up along with the knowledge.

Haha you know it

2 weeks 24
2 weeks 18/6
2 weeks 16/8
Rest 12/12

thanks man

Someone did a pretty extensive chronicalling of testing the pros and cons of 16/18/20/22 and 24 hours of light in veg. His conclusion was that 20/4 offered the best overall growth. YMMV

 

[Twisted pleasur]

Ive always done 24

Eager Beaver, Go For Bust, If It Aint Broke Dont Fix it.

But last week I switched to 18/6 took that electric and moved it flower.

So far so good. They are just as happy and healthy. But I want to see if the transition to flower is better. Im also going to try the whole 24 dark as well.

Would love to see more takes on what people think and have treid in here. I mean how much difference are we talking here?

it actually depends on how bright your vegging lights are, if the plant is receiving an optimum amount of light during it's lights on period, then it will be happier with a dark period of 4-6 hours because it does perform some of its processes better during the dark period.

if you veg under week lighting then 24/0 may be better.

also a plant vegged with a dark period will start to flower a bit quicker and therefore with a little less stretch bacause it will already have some flowering response 'in the bank' because it has had a dark period.

there was a long and bad tempered thread about this a while back.

[Graham Purwatt]

yep 18/6 always seemed best to me, they seemed to respond better with the 6 hours of dark

 

[Mt Toker]

St3ve, how many strains were tested in that? Indica/Sativa have different needs all around.

That makes allot of sense.

For me for instance I use several 400 MH so thats plenty IMO

But if ur veg under only a few T5 or Floros then 24 might perform much better.

Never looked at it like that. Makes me feel better about my decision to make the switch.

And the fast flower initiation with out as much stretch would be amaizing.

Looking forward to my resualts.

Ok So?
Cloning have always done 24 under
20watt
4100k
T-12

Per dome. Im afraid to try 18 on those cause they do so perfect.

I use shelves and there is a floro over the dome and under each shelf for the dome below and also for warmth in the root zone.

The warmth would go away with a extented dark period.

Idk

Nice new angle and perspective on the subject.

I didn't mean to bring bad tempers about, I even agree'd with the person I quoted.
