Thanks for taking the time to reply after I was somewhat rude. I am glad you recognize that a plant cant be forced into flowering. However, you say you first give the plants 20 hours and work your way down... this is not what the name of the technique implies. 12/12 FROM SEED, means you do it straight away. How can you say its 12/12 from seed when you are giving it 20/4 from seed lol its the same as any other grow just small veg time.Its definatly beneficial if a fast flowering strains is used.I can say a lot of time I use 20 hrs of light on seedlings for about a week then down to 18 hrs of light for the next few weeks,after about 3weeks switch to 12/12.Like 12/12 from seed but with a kick.
Flowering can't be induced on a plant,it has to be mature enough,alternating nodes doesn't always occur first.
ONE MORE TIME.......12/12 fs is the best way to have a perpetual grow with a single grow space or to identify males and females as quickly as possible.
I apologize because im not good with words or the best at explaining things.I just hope you have gained something from this thread like I have.peace
I have been using the mainlining technique to get the 2.5 months of veg in... they are still less than 1 meter tall now in flower. I want to try increase my plant numbers and do single-cola plants. If I use 18/6 lighting in veg instead of 24/0 how much sooner would you GUESS that I could start flowering? Because I have a 180cm height limit and this OG GTH#1 strain nearly triples in height at flower from what I've heard.
Its difficult for me to determine how much they stretched this time around because they suddenly started stretching under 24/0 just before the flip to 12/12.
@SirGreenThumb:
I cant believe some plants mature within a week and a half thats insane!! No offence but are you sure they arent hermies of some kind? :S I waited 2.5 frickin months on 24 hour lighting (partly responsible I know) to see the first white hairs. Oddly enough too the females (5/6) all showed sex before the male was even recognizable. Oh and boobs (. Y .) :F
