2 weeks into flowering and I may to change the dark times!

[Weed Pharma]

My flower tent has 2 clones @ 2 weeks into flowering currently with lights on 8AM-8PM.

If I were to change that to lights on 8PM-8AM. (for more heat at night)
What would be the best method to accomplish this?

[Canuck147]

I would do it one hour a day. 1/2 hour on each side.

canuck147 says it right max id do is 1 hour everyday. 1/2 hour on both sides. slow to not cause shock.

Leave it dark for 24 hours. Then continue your regular schedule.

Excellent idea, I'll remember that if I ever have a power outage.

I second. Long dark periods just reinforce the hormonal signal to flower. Even the stretch

[Royal Nugs]

King is probably right on this. The plants really only care about getting their 12 hours of darkness. I freak out at the prospect of causing hermies.

I recently lost power and had to recalibrate my times. I'm rolling back to my original 2pm-2am lights on by 30 minutes a day. I'm at 4pm-4am today.

Probably overly cautious but whatever

The reason I was so quick to answer, is because I had a scheduling conflict where I couldn't turn my lights on when I should and I resorted to leave them off 'till the next cycle. I never had any ill affect from it. I wouldn't recommended too many times in the same grow. Don't want to push your luck. Once per grow. I don't think is going to hurt.

[Royal Nugs]

Assuming relatively stable genetics, I agree.

Until I get a few more grows under my belt, I'm going to continue to be cautious with these kind of things. It's good to know you have experience with this. You're a good dude King. I don't care what Greenie sais about you.

Leave it dark for 24 hours. Then continue your regular schedule.

This, cannabis doesn't care how much light it gets. Just make sure they don't get less than 12 hours of darkness in flowering.

So much good input for this-
I was away for the weekend and the temps dropped to 63f and I had 2 seeds sprout in the veg tent, upon return (surprised), but the temps are on the way down and I do not want it to get any colder in either tent!

Keeping them in the dark- it will be if needed!
