light question-- Need help

I will get right to the point.

Been some time since i grew inside and i have 4 lights in same room. Two timers i had 18hrs and the other two 12 hrs. did not notice till a month in. Well it is all on 18hrs now and they are all about the same height now- tall as hell. the ones under the 18hr light from beginning have alot more bud on them and the others are just starting to bud. I do not see no hermies. My question is will these other ones that are behind, bud fully still and should i turn my light down to 12hrs because of this? I am not in any rush so i would like to keep on 18hr to bud.

20/4 to harvest with autos..sometimes if they are on a roll ill let them go 24/0.Autos are on a strict time table,running 12/12 will lower your yield.However it will save you some $ on electricity if you arent worried so much about yield.

So my 18 hrs is ok. Write?

My ones just starting to bud will bud fully then write just a little behind???

I run my autos on 18-6 because I'm worried about my nosey neighbors, & it works just fine, but like Resinhound said, 20-4 or 24-0 will produce larger yields if that's what you're after...

18/6 will work fine yes.

18/6 is good, many go 20/4 or even the exhausting 24/0,

they will be fine, but the deal is in the lights you have,

at this point the more light the more bud
