personally i believe male/female to be a good portion of "roll of the die"... growing indicas (which i don't :P) i wouldnt care about giving less than 24 hour light in veggie because indicas typically dont need as much light... however with sativa i would always reccomend either 24 hour light or 22-2 for a 2 hour cool down because sativas need more light...

there are too many opposing opinions and "facts" out there for me to choose a side. therefore o go by a fact i do know for sure... sativas need more light than indicas and are found naturalized closer to the Ecuador where daylight is the longest

24 hour light will cause higher temperatures too so keep that in mind

Read it once in Jorge Cervantes grow bible...

But I actually saw it happen too in a grow, we had to pull plants out of a hydro system and put them in soil to save em, turned out 80% female....

were talking hundreds of plants...

give me a day to dig the quote up....

Vegging 18 hours is the best. Plants depend on the sun for the seasons. When you start getting shorter days then the plants know that they must reproduce before the cold weather shuts them down. 24 hours is a waste of energy. Plants need to rest Just like every living thing

they obviously dont NEED rest if so many people (including myself) use 22 to 24 hours light and have no problems,, i would even say i have a good female turnout with 22to24,,,, i just see it as a few extra hours of photosynthesis

and the debate continues....

A plant needs time to rest and rejuvenate!!!

not according to Ed Rosenthal and other expert growers. Other expert growers like Jorge Cervantes disagree with Ed so there doesn't appear to be any proof.

i have tried all three - 18/6, 20/4 and 24/0 and noted no real difference between any of them but i figure the plants will get plenty of rest once i switch to 12/12.

What i think is most likely is 18/6 may increase potency and 24/0 may increase yield but again - this is just conjecture based on some things i've read.

I believe from experience that my plants have always grown better under 18/6...i do believe that any living thing needs a break from it's daily work routine...and a few hours of light off is actually better for the plants, gives them time to reapir minor problems, and to just plain rest.

Get back to me on that when he can walk on water.

Just because its in print doesn't make it true.

A bunch of Einstien's theories have been disproven. Along with Hawkin's main theory. (Hawkin himself came out and said he was wrong)

Yeah he's good. bBut the genetics are still being screwed with.

Don't forget, the earth was flat at one time.

OK - from the biology thread i have some hard science from asf2j as to why 18/6 is better than 24/0 or 20/4!

Biology lesson.

Yippee!! i LOVE science!
