LIGHTS ON LIGHTS OFF

What is best for klones 4 weeks old 12 and 12 or 18 and 6 ?

18/6 to keep them in vegetative growth or 12/12 to send them into flower (bud). Your decision to make.

18/6 or 24/0. I prefer 24/0 under my t5's, 36w. No timers, just plug 'em in.

Exactly how I do it.
I responded with OP only options.

I run 18/6 from first showing of root structure to 6 weeks and switch to 20/4 after that. The lights out time gets you better root growth. Yeah, 24/0 will grow plants, but more roots = more bud!

Exactly Dr. Who, the ladies need a few hours to rest. I have always let them get at least 4 hours of lights off. They need time to breath and digest all of the food they have eaten that day. lol

From some of my reading, cannabis doesn't require a night cycle during veg like some plants.

I've also heard burning the extra electricity for 24 hrs doesn't give much improvement.

Since I grow in a microcab I think I only had lights on for 14 or 16 hours. Unfortunately I was shutting down with I came across the gas lamp method which is what I'll try next.
