can cool temps induce flowers?

[bconway]

My northern lights mother, & most of her babies have started to flower while still under 18/6 400 mh. My white widdow mother & babies seem to be ok. I'm wondering if the cool temps in my veg room are causing this. 60f dark, & 65f with lights on. I put a small heater in the room this morning, & will try to bring the temp up to 75f. Will the affected plants re-veg, or should I trash them, & start over. I'd move them into the bud room, but it's at capacity. I have grown outdoors for many years, but have been forced indoors after loosing 2 crops to *%&$# theft. It's like learning to walk all over again.

bconway, welcome to the 420 family. I'm sorry, but I don't know the answer to your problem. My grow room goes down to 60f when the light is off. I'm growing lowryder 2 which of course is auto-flowering. I have covered my air intake to prevent the cool air from coming in. I wouldn't trash the plants.

They are probably just naturally showing sex. If anything the cold slows them down, but shouldn't induce flowering or stop it. 60 degrees is on the edge of growth stop (They say thats 50-55f).

Thanks for the replies, the reason my room has been kept so cool is to try to slow the growth a bit, but it could be that my nl mother is getting a little old (like me).It's over a year old, & has produced many offspring. I already have a replacement mother started,(white rhino), I like to have a couple of strains going. I think I'll keep the mother until I have room in the bud room, & give the clones to my son. He can still grow outdoors, but he has some cfl's set up so he can get a head start on the warmer weather. If he plants flowering clones in the spring, he'll probably be able to harvest twice this year. I love this site, & have used it as my main reference resourse since Oct. when I first built my rooms. My first 2 indoor grows were 20 plant sog using dwc, but this time I'm using a soil less mix (I like playing in the dirt).

Make certain your timer is in fact set to 18/6 and that you don't have any light leaks that are messing with your light schedule. Cold temps. will not induce flowering, it will only slow growth.
