18/6, 20/4, or 24/7?

Who out there has experience with at least 2 out of the three of these veg cycles? What would you recommend and why? Thanks.

I have been wondering this too.. I've been vegging for a couple weeks on 24/7... It seems drastic to switch straight to 18/6 or 12/12 like the norm... This time I am going to slowly take an hour off every 4 days.... from now (24/0).... till I get to flower (12/12).... see if it makes any difference, maybe reduce stress?

yeah, I heard that 24/7 gives continuous growth, but then I also heard that there's more growth during the dark hours? anybody got proof of one or the other?

18/6....i use to go 24/7 thinking they would grow faster with longer light...but they like the dark too...it's part of nature...I only go 18/6 unless its a new clone..

that hour off every few days sounds sensible. kinda like to simulate the slow transition into late summer, early autumn, huh?

thats kinda where I was headed with this. (leaning towards something more natural)...do you notice a significant difference in growth or overall health on 18/6?

yes.....look at my 3 week old plants....

phuk! is that 3 weeks from seed?

no from cutting for clone..they were very small clones..3-7 inches tall...they are an average of 18 inches tall right now..they were cut on 1/12/08

ok, i just took a quik look at ur journal.....clones or not thats still pretty impressive growth for that amount of time. nice setup.

could i switch to 18/6 now without stressin em too much or should I stick w/24 until its time for flower? they're 12 day old cfl soil babies

ive done 24/7 and also 18/6 20/4 23/1
so far ive found 23/1 gave them pretty decent growth you still get a bit of a dark period and it gives the lights and ballasts a chance to cool off a bit
the first month for my 1 plant i gave her 24/7 and she grew twice the size of all my others
for my next show ill experiment with the 24/7 (23/1 either or not sure which one yet) and 18/6 ill do a journal on it for sure =)

it will be okay to switch them to 18/6 aslong as they arent getting anything less than that they wont flower =) if your worried about electricity consumption then do it if not you can stick with 24/7 if you want

Yeah i used to do 24/0 when i only had fluro tubes but now i use a hid for veg i found that 24/0 made them look a bit tired so i went back to 18/6 and i think they looked better and seemed to grow more quickly with rest

not worried about electricity until i move up to mh/hps...just wanna do the best i can with what i got. judging from the different responses it seems like there are other factors to consider like plant strain, environment, type of light, etc. i'll just stick with 24/0 for now and see what happens. they look pretty healthy so far. it's pretty fun too, this is my first (educated) attempt . I used some seeds from a brick batch that suprised the hell out of me and my peeps. it was damn near as good as some real bombay.

thanks for the help y'all. gd nite.
