24/7 vs 18/6 light cycle

What would be the reasoning for leaving them on 24/7 vs going with an 18/6 light cycle? Wouldn't the plants need some time to rest? I am growing organic in soilless mix.. what would you recommend?

 

24 hours = faster growth
18/6 = slower growth & faster preflowering

 

Its really a matter of opinion. Some say 24 hours = faster growth but my plants grew faster once I put them on 18/6 then they did on 24hours. In the long run I think its just gonna cost you more than its worth to have the light for the extra 6 hours.

 

The cost to keep the lights on an extra 6hrs aren't really worth the benifets of having them on...

 

i think the biggest reason to use 18/6 is to reduce heat in the grow room (and some minimal cost savings on electric bill).
i think the rest of the reasons are mythic or anecdotal.

 

go 24/0 with seedlings and clones until they are established, then switch over to 18/6 or you can go 20/4 you want to give the plants a little rest they will grow in the dark.Some people will argue this but most have a dark period.

 

i won't argue they grow in the dark. I would argue against the need for rest. i mean it's not like plants have muscle fibers that require resting before use.

also - one of the benefits of indoor growing is you can leave the lights on 24 hours a day!

now having said that - i have heard about folks getting more males and hermies using 24/0 rather than 18/6 but my experience has been - it doesn't really matter.

 

Is it true that youre more likely to get females if you interrupt the 18/6 with an hour or so of light in the middle?
I read this on one of the guides to growing weed, but there are so many out there, who knows how much bs there is.

 

i have a feeling we are wading in it! my opinion is - a lot growers think something works and makes their plants better but the reality is - the plants are doing well IN SPITE OF rather than BECAUSE of things growers are doing. myself included of course.

 

Thats hitting the nail right on the head.

 

Yes to all that.
