What should the temps be during the dark 12 hours?

What are the normal temps when the lights are off for 12 hours I'm 14 days into flowering or I should say 12/12 and my plant still hasn't shown it's sex yet!!

If they are from seed and you did not veg long then that is expected. 4 days or so will make the difference. You want to keep your temps even as possible. But ideally you dont want your root ball getting cooler than about 6-10degrees diff.

How old are they?

My plant is 55 days old and tomorrow will be 2 weeks into 12/12 this is my first grow!

Good. It's old enough, you'll see something soon. Don't love it to death.

If you can, post some close up pics! It's really hard to tell sometimes but they WILL show under 12/12 eventually. I have inaccurately(and impatiently) determined, or maybe proclaimed is a better word, sex before.

Ya I'll take some pics of it once I'm off work today and post them. In running at like 73fwhen the lights r on and like 60-65 when lights are off, but I just got in my HPS today so I'll be running that from today on, I'm sure the temps will go up but I have my tent vented pretty good with a scrubber, if it get really bad I'll get a cool tube too!
