Stinky,what are the advantages (+) of keeping your plants on a 24/0 as oppose to a 18/6 ?

In my mind it's to do with keeping the plants smaller (height) but does it effect the bushyness & end product ?

Also would i keep them on 24/0 right up until flowering & then do you put them straight onto a 12/12 ? I only ask because i usualy go for 18/6 then 12/12,but after reading that you use 24/0 my brain is telling me to evolve and play follow my leader...

p.s. Those nutes i bought are the dogs bollocks,alomst as good as this thread as it stops the uneducated amongst us from having to start new threads for what some would call newbie topics.
