4 days into 12/12, still no sign of floweing

On Saturday night, I switched my light cycle to 12/12 after gradually taking an hour off the light schedule until it was 12/12. But there is still no sign of flowering. I look very close on the stems and there is still no sign that the plant is a male or a female. There looks like there could be some kinda pistil looking things on one plant, but they also look like the could just be forming leaves. Whats a sure fire way to tell the sex of a plant even when the plants have decided not to flower yet?

dont worry they will show and the later the better as males tend to show before females you should be looking on the main stem about 3-4 nodes or stems down hope this is little help

waiting is the only way buddy....

gradually turning to 12/12 would possibly be a reason they havent shown yet- an abrubt change from 24/0 to 12/12 would trigger it better I believe..

I saw female pistils w/in a week for sure...

Give them a few more days and they will be pretty horny....

next time just flip to 12's

I'm not saying that your plants wont flower because they will probably, but the sudden switch gives the plants enough of a shock to start them flowering, when the lights switch suddenly the plant thinks fuck its winter im gonna die soon better make some buds quick

thanks i'll post some kind of update when they finally start showing some signs of flowering

took 12 days for mine to show sex but it will happen

never gradually take an hour off until you hit 12/12.. always go straight from 18/6 to 12/12

some show signs in 4 days some can take 14 some even longer u should c changes really soon tho a microscope is a handy thing 2 have for this stage

i popped a seed about 6 years ago i got from this really good bud i bought i knew completly nothing about growing i dident even no there was male and female plants light cycles was all i knew
This thing grew for a 1/2 year or more and showed no signs of sex and grew till about 7 feet of hemp

it could take up to 3 wks to show sign of flowering

Yes yes, cali-high is right, I'm two weeks and one day into my 12/12 and out of 3 plants only two just showed signs of sex yesterday and I had to use a 20x mag glass to see my first set of pistils.


BE PATIENT, you'll have plenty of free smoke soon enough...impatience only pays off in premature smoke.

still no signs after 6 days, although one is showing signs of a possible FEMALE!!

Oh and in regards to my plants, I am showing far more signs of flowering than you are....with only a few more days into my 12/12.

and maybe it has to do with how we started their flowering, I didn't just go from my 20/4 into a 12/12. What I did was, I put my plants into a 36 hour dark period before switching the timer over to 12/12. My first pistils appeared at 7 days, I'm now at day 9 or 10 completely into flowering.

And this was something I have now read in numurous books that come highly recommended so that was my source if that helps.

dude.. you veg at 18/6 then you switch over to 12/12 right away.. no 20/4, no 36 hour dark period lol where did u learn to grow?

20/4 will promote faster growth than 18/6 fact.

NO...actually I did veg at 20/4 and I did a 36 hour dark period...why are you saying I don't...where did you learn to read? Stop trying to be a resident expert, as I said above this is in many highly recommended books. The people that are doing this for a living on large scale 50,000 sq/ft warehouses taught me to grow...anymore arguments you want to start?

I can't stand people who argue with a system that works..just because it's different than what you do...absolutely immature bro.

Marijuana Horticulture by Jorge Cervantes, thanks....my system works just fine for me DUDE LOL

My plants are green, they grew, they flowered....guess what I did works....so what's wrong with where I learned or how I grow???

Stop trying to make fun of or cut people down, that's lame

I dunno about fact....I've heard alot of mixed opinions about just how much growth you actually will see after 18 hours of light. Rumor in the plant world is a plant can only use 18-20 hours of light a day.

Not saying that's right, but it provides a great counter argument for what you claim to be fact.

Besides, there are certain things a plant does when in the dark to prepare for it's light period again...just like people plants need to sleep a little bit during the day it's part of the process of photosynthesis.

I believed what you are saying up until recently when i read an article written by ed rosenthal, anything this guy says I take as fact.

He was basically saying that a plant doesnt sleep or rest. Light plus water and nutrient is what make the plant grow, take one away and the plant grows slower. The plant doesnt grow anywhere near as much foliage in the dark as it does during daytime. He said the only real benefit of 18/6 over 24/0 was that you could use this to time your plants to be ready. If you need the plants quickly 24/0. If you want to slow the growth down so that they will not be ready to flower early, then you use 18/6.

Who cares if you go 20/4 or 18/6 or 24/0? They are all accepted vegetative light periods. I personally have always thought that the more light the better, I'm no scientist so I don't try to dispute that 18/6 works just as well.

What I've never heard is that 20 or 24 hours of light does ANY harm! If it doesn't do any harm, and no one has proven that 18 is JUST as efficient, what does it hurt?

I have also heard of the dark period before flowering, although I don't use it myself. I switched to 12/12 straight away and All plants showed sex within the 3rd day. Just lucky I guess.
