What is the best way to sex plants and why?

What I have been doing is plant the seed, wait untill I see three sets of nodes or so, then put them under 12/12. They usually take about 2 weeks to show(some sooner, some later), then I put them back under 24 hrs lite. This way has been successfull.

I'm hearing that this method has its drawbacks like stressing the plant to become males/hermies, and that i'm actually setting the plants back a few weeks when compared to letting the plant just veg untill it preflowers.
Is there any truth to this? What are the pros and cons to either method? +rep to all that helps.
Thanx.

i wouldnt stress the plant like that.Unforunitly i want untill 12/12 cycle but now im using feminized seeds. They are garunteed to be female appaently!!

I had a guy tell me the other day to take some clones off each plant mark them and put them on 12/12 to get the sex. Do this 2 weeks before you want to flower your plants and it should help

i definitely sets the plant back. plus it also encourages stretch because all plants stretch during 12/12. let the plant grow till it shows preflowers, usually about a month. if not, when you put them in 12, leave them there and just cut the males.

What you have done in the past works obviously, but it sets them back more then you realize. when the plants are vegging they are producing hormones that help it grow or veg. When the daylight hours decrease the plant quickly starts to produce different and very powerful hormones to flower so after your initial 2 weeks under 12/12 you can sex them. when you put the plant back under 18/12 or better 24 light schedule the plant has to start the process of vegging all over so some of the hormones destroyed during flowering need to be recreated and some need to be destroyed...this takes time. Even though you will see some initial growth within a short period of time the hormones are still not going to be right for max growth for close to six weeks after switching back to long daylight hours, this now puts you approx 9 weeks into your grow. Flipping them back to flower anytime sooner is a great way to produce hermies if the plant has a strong tendencey. (remember people re-veg plants all the time with no hermies and essentially you are re-vegging a seedling).
I prefer to let the plant grow like normal and then after 5-7 nodes pull the bottom 2 axial branches for clones put 1 clone under 12/12 to sex and the other can left under 24 in case it turns out to be a female. None of the hormonal or light stress as oppossed to the other way. Also it is very easy to sex this way instead of peering at preflowers till your eyes cross... some plants are much harder to tell then others.
Sidenote: bagseed or ?

Thanks for replying guys, Good luck with your fem seeds Truestoner hopen their all females for ya.
Sounds like you three have the same method....one that I didn't think about. Great tip. How tall do they typically get by 1 month?2months? I usually veg 2 months or 24 in tall, sexed and fimmed before budding, they end up being decent 3-4 ft plants. Would doing it your way make bigger plants faster?

+ rep guys.

I wish i had the room to put another light to be able to put my clones under 12/12 to sex them!! Soon enough!! LOL

you could always stick ur dong in its flower and fertilize it

taking the clones and sexing the clones is way faster than your way of flower then reveg . this way your veggin plants are still veggin with no setbacks or stress + you get to sex them at the same time. doesnt that sound better? take the clones 3 wks b4 you want to flower. your way works but imo it sets you back atleat 2 weeks. just make sure you label the clones so you know which plan they came from
