18/6 switched to 14/10 or 16/8. If you use weaker lights(leds, cfl and small hid) then you do benefit from the extended light time. But if you use big lights (600 to1000w hid) then you at max want 18/6 for the first three weeks then switch to 14/10 or 16/8. Even though 20/4 might work I have experiened better yields and quality in the end. They are not fully ruderalis remember they have some traits of regular strains. Rest is good after a long day of sun photoperiod. Where as veg cycle doesnt matter with photos but flowering does. Just because it automatically flowers doest mean it doesnt need rest period. Had some big yields from these little plants doing just that.
 
Weaker lights?
If you reduce the lighting time too much it will decrease your end yeild unless the seed bank states it needs to be 14-16 hrs on the rest off. By the way LEDs are just as strong as any HPS just lower heat output and a better color spectrum :2cents:

Also, I would assume LEDs have better light penetration. Correct me if I'm wrong.
 
I grew 24/0 for my first several grows and had fair results. What I thought was nute burn, really plant stress happened often. I have not grown the same strain twice, still looking for my special girls. The last three grows have been 20/4 and I have had less stress and better yeilds. Plants still seem to grow as they please, poor light disipline on my part but the buds are fatter. This grow I had issues but the plants resopnded quicker and turned out fine. I have not noted that the plants mature quicker either, just seem more prone to stress and lighter buds.

Depends on the W on DIODES.
1w works buth not penetrate well (most common).
3w works realy nice (what i use).
5w-10w best buth way to expencive atm and tbh the point of leds is low temp, noice and power consumption so i wouldnt use higer then 3w for a few years or ever.
I pay about 10$ a month to have my grow running (witout the neuts) and to me thats the point of led stealth growing.

I like to use 24 hours for the first 2 weeks then switch to 20/4, then I go to 18/6 for the last 2 weeks to dense up the buds.

How do ure plants make roots The first 2 weeks?

Like any other plant that grows, don't forget, the plant wants to live, you can't say it won't grow roots cos light is 24/7.
