RUNNING LIGHTS TOO LONG?

Greetings, i was just wondering out of curiosity if it would be detrimental to a plant if it were exposed to more than 18 hours, upto 24 hours per day. Either state? Thank you.

No, actually 24 hours I heard can help the plants health..Dont know if it's true but it's just what I read.

some growers veg under 24 hours, and swear by it ... I agree with the experts and botanists that say a plant needs those dark hours to assimilate nutes, and grow ... whoever's right, I grow 18/6 and 12/12, always have, see no reason to change ... :smokin:

I prefer 20/4 my self but that is just me

i always used 24/0 lighting schedule for vegg with excellent results. then i would switch to 18/6 for a week or 2 then to 12/12. everyone has there own methods that work for them. over time you will figure out what works best for your set-up.

It would probally be best to have some twilight hours. But that's just personal opinion based on nothing.

I want to start them inside for just a little while and them put them outdoors
so can anybody tell me what kind of lighting cycle I should use while they
are inside. If it matters or helps it's Big budXNL#5. Thanks,

I was wondering the same thing. I have a buddy that was growing 24/0 and it flowered under low light intensity. June 21 is the equinox so the day length is decreasing after that anyway which induces flowering. I think vegging at 24/0 will work. You could try to increase the day length starting at 12/12 untill you put them outside which should give you the longest veg. growth and largest size if you have good light intensity and are not worried that they will have time to mature fully. I guess that it would depend on whether that particular strain would have the time to finish properly at your lattitude under outdoor only conditions

just use 18/6 or 24/0 till the go outside. if you start at 12/12 and increase light hours as bro said all you will do is confuse the shit outta the plants till the go hermie imo.

just figure your dawn-to-dusk hours ... about 13 right now where I am located ... sooo, indoors at 18 hours, if they went outside now, that should trigger flowering ... simple ... :smokin:

24/0 veg 12/12 flower 10-11/13-14 late flower 18/6 clones...successfull results

Justaseed,
I am not saying that your opinion is without merit, as you seem to have more experience in daylength than I do,but there are some things that just don't add up here to me.
First the trigger for flowering is in decreasing day length.which happens June 21 everywhere in the northern hemisphere There are modifiers such as temp,light intensity, available nutrients,age, etc.
I think the answer to Madja's question would have to do with when you want to induce flowering by decreasing day length. If you have a strain that will have a problem maturing at your lattitude then decreasing day length by having say 24/0 cycle indoors before putting them out will trigger flowering the day you put them and that's a good thing.
In the North we can't put our plants out much earlier than june 21 so increasing the light cycle while indoors up to a point where the natural day length is longer than the artificial day length will result in a longer veg. which will increase yields as long as your strain will finish in time. That means 12/12 untill they are put outside. If you have good light intensity indoors then there shouldn't be a problem otherwise they may be confused

:rasta: :thumbsup:
the day length on june 21 is like 17/7 here so I guess you should increase

a 24 hour light period will give you more males and hermies in my opinion. Thats from trial and error, so.
!8/6 or 20/4 is better.

I go with Jdog on this, too ... longer daylight hours tend to produce more males, ... I read that in seedbank posts, and, since I have grown indoors since 1976, and only had 2 males in those 30 years, (and NO hermies), what I read should be correct .... or, ... I am the luckiest SOB in the world ... :D
