Reply With QuoteI have tried them both and I prefer 18/6 versus 24 hours straight.. Plants are living things and they need some rest too.
I've done 18/6, 20/4, 22/2, 23/1 and 24/0. I wanted to know too. For the last 6 months I've been sticking to 24/0. Much faster growth, shorter spacing between nodes. Less stretching. pure indicas in soil reach a foot tall in 7 days and are bushy straight from just rooted clone. My clones root in 5 days, sometimes a few take 7 days. in 24/0. In 18/6 clones took 10 to 15 days. In 24/0 They are always perky and never get droopy. When you make the initial switch to 24/0, they will get droopy at end of day and stay like that for another day. Then they come out of it amd remain perky. Some do blow up like crazy when flip to 12/12. Not all do.

My only input would be this, every living thing grows when they sleep. How many times have you gone to bed and the plant seems to grow over night. How many times have you planted a seed, gone to bed and the next morning it is a seedling. Not only weed everything I grow. I think the dark time is good. Just my opinion and I grow a lot of stuff, veggies, flowers you name it.

I prefer 24/0. I use 18/6 or 20/4 if I wanna get a little stretch to take some clones.
I get the point you're trying to make, but in reality the plant grew so much because you weren't looking at the plant every 15 minutes. I actually put my germed seeds under 24/0 light until they pop(a day or 2 max). Quick googling gave me this, "Dark reactions dont require light, but they arent inhibited by it, either. For most plants, the darkreactions take place during daytime." http://www.slideshare.net/Christian_...esis-in-plantsOriginally Posted by chrishydro
I say 20/4 because you only lose 4 hours of light, but you save a good bit of energy too. That and it keeps the temps not too high. I'm not a fan of 24/0 over 20/4 because I didn't see a noticeable difference. I'll agree that 24/0>18/6 though. I'd like to see some sources that say plants must have a dark period too from the people saying that plants need rest.

So in nature. How about alaska . Sun doesnt set for 3 months. Plants and trees grow just fine. Some of the lushes forests inbthe world grow there too.

It's hard to find anything non-forum related when you try and google if they need dark during vegetation, but the first two (and only two, so far) articles I found say they don't need any light, saying they're "c3 plants", whatever the fuck that means.

We're trying to have a constructive discussion of 24/0 vs 18/6. Saying "nature is best" doesn't add anything to the discussion. Post an article, post some research someone did, post anything that says cannabis must have a dark period and we can get to discussing it. Btw research doesn't count as someone doing 18/6 and saying the plant grew better. Research would be either have 2 grows at the same time one 18/6, one 24/0 or doing one grow with each time and comparing the results.
You can't be serious about Alaska right...Do you think it's all snow or something like you see in the movies? Hyroot is making the point that with 3 months of darkness the plant life still thrived. If plants had to have a dark period wouldn't all plant life in Alaska die and cause the ecosystem to fail?
