Full month of 12/12 with zero sign of flowering?

[dannonamous]

I've got three unknown plants under a 70w hps.
Vegged under 24hr light for about a month, and flipped the timer on on november 18. Today is december 18 and there isn't a calyx or ball sac anywhere.

I've popped in at night a few times to make sure the timer isn't messing up, and it does stay 100% dark in there.
The only other thing I was thinking was maybe the cold is stressing them too much? It stays around 40-50 degrees fahrenheit, which sounds cold but I've had other plants do fine in that range.

There's no wilting, yellowing or any other signs of stress, anybody got any suggestions?

I'll get pictures up either tonight or tomorrow.

Hey bro the cold could delay flowering for sure

What strain?

 

[dannonamous]

unknown

Thats why I grow 12/12 from seed/clone. Fuck veg. Is there enough root space? If its rootbound, it wont hardly do shit.

Light leak, I had the same problem in my first grow there was a steady small stream of light comming from my veg chamber, an 18hr a day light source could be messing it up

I'm so smart

i would guess light leak if all are not flowering.

double check timer, i had a timer that would turn on for 2 hours during dark cycle, lucky it was caught during veg.

Are they sativa, or should I say, do they look sativa?

 

[IE2KS_KUSH]

I've popped in at night a few times to make sure the timer isn't messing up,

So...the thing is, you may have a light leak, or maybe someone is compromising the dark cycle by going in during lights out...I'm just saying..

and it does stay 100% dark in there.

Except for when you go in to "check" on them though...

As another posted said, the cold can delay/stress them as well...if I was a betting man, I'd bet all my money on hermies, lots of them..
Good luck.

Same thing happened with my Old Time Moonshine - Just wouldn't flower under 12/12. Changed it to 11 hours light, 13 hours darkness and within a week it started throwing hairs out and flowering.

So i say try changing the light cycle.

 

[dannonamous]

Thanks, I'll have to try that.

And it's definitely not a light issue.
The only light in the entire crawlspace is the grow light, and when I say I've popped in at night I mean I've opened the door (which is outside) just enough to see if the light's on or not, and being nighttime, no light gets in.

All three are in the same box, soil's area is probably about 20"long, 9 wide, and 9 deep.

Typing that, I realize they definitely could use more space, but at the same time I've had the same number plants in the same box, in similar conditions, with less light, and they flowered without a hitch.

If it's 40-50F I'd bet on the cold temps delaying the flowering. Is the box on the ground? Raising it with crates or something off of cement or just the ground will help, a heater even better to get it up to 60-70 range at night.

Cheers

I'm betting that it is a Sativa of some type and generally most sativa's come from Tropical/warm climates, i have had a sativa that took just over 3 weeks to throw its first female hairs so if its in the cold it will delay its flower cycle

Get a small heater in there to keep those temps up in the 70deg range and if that doesn't work after a week change the light cycle to 11/13

And as Raphael said if they are sitting on the cold ground the rootmass will not be in ideal condition and will take forever to warm up

Hope you get it sorted.. any pics so we can identify if its sativa or indica

It's a christmas miracle...

December 25 was the first day I saw definite pistils, and on all three plants.

Now the runt (that I always had high hopes for) is kicking the other two's asses and is beginning to bud up, just like I knew she would.

I'll post pictures if I ever fix my camera...

 

[PhenoMenal]

if its not a light issue, autoflowering gene possibly??? (no idea, just thinking out loud)

 

[V1AAA]

what was your problem?

 

[Researcher]

Did it warm up or did you get a heater?

 

[dannonamous]

I think the problem was just the cold temps holding everything up, but I didn't do anything to fix it.

It got down around -40 outside for a few nights, so it was probably just around 35-40 degrees in the crawl space, but they seem to be liking it - They're budding a lot quicker/fuller than my last grow at the end of fall/beginning of winter, so my hopes are high.

The only problem I've got now is trying to keep them ot of each others' space.

just an update

 

[chuckyoufarley]

my flower cycle has always been 10hrs on 14 hrs off
