Do you understand photoperiod?
They show sex after u switch to 12 12

24 hr light is good and pointless. There is no plant that gets 24/7 light. Plants benefit from a rest period imo. 18/6.
I did 24 .0 and mine had fast growth and did fine. I've never tried 18.6 though.
Do you know of any studies or is this just ancedotal from your experience?

I done it both ways (24/0 and 18/6). I see that the plant grows better (imo) on 18/6. Structure wise and less stress. Like said before no plant in nature gets 24/0 light cycle. But really the difference to me came down to the light bill...

I see not that much of a difference between the schedules, and think 18/6 is better, so why pay the extra 6hrs of electricity.

I could use the energy savings but will it slow growth?
And you say structure. Do you mean it has better structure, more bud sites? Because that would make it worth it alone

I plan on mainlining this one so that's why I had it running 24/7 so I could get to the 5 or 6 stems quicker, I'm going to slowly introduce my plant to the darkness since it's already been a week of straight light.

No it won't slow growth. Plants use the dark period to convert starches and... Well... grow lol. I get better growth from what I've seen. Structure I meant More stable stems, not necessarily more bud sites or anything.

But still, the difference was barely. It's about the same, both work. They do droop before the light goes out and they're bigger in the 'morning' on 18/6 so I know they want 'sleep' lol.

I did 24/0 my first few years and then it just didn't seem worth it at a certain point

If you use CFL's, they don't achieve enough light saturation and quite a few articles are saying it's better just to leave them on 24. I'm not sure how much merit can be placed on the sources, however I can say that with CFL's 18/6 took 2 weeks longer to get to the same point I am now when I Veg'd for 24.

For the the first 2 weeks I had my seedlings under 24hr light.4 36 watt cfls. node spacing was really good. after I transplant them, they go 18-6.
