Switching to 12/12

Hi

Im about to go from 18 to 12 hours of light. My veg plants sleep at night while my flowering will take place at night, to take advantage of cooler temps. The plant will have a prolonged period of either sunshine or darkness during the switch.

My question is, is there one that is better?

Should they go through an extended darkness (22 hours, vs the regular 6) before getting hit with 12 hours of flowering light.

Or, should they get an extended light blast of about 28 hours, before going into 12 hours of darkness?

My personal thought is that extended darkness will help signal flowering. Are there any thoughts, or am I overthinking this all together?

Thanks

If anyone is wondering, I have decided on a hybrid plan. Since my veg to sleep at 11 pm and wake up at 5, and flower will go from 9pm to 9 am, I will pull the plant at 5 pm, for an effective 12 hours sun, put it in the dark for 6 hours till 11, fire up the flowering sun, and slowly dial the 2 hours back to 9. Sounds like the most stress free option.

Cheers

You don't have to do this for indoor plants my friend. If you can make dark hours longer than light hours for through the switch that's great so that's generally the advice. But many times I end up giving them 20 hours of light then they switch to 12 hours dark, 12 hours light. Never an issue that I'm away of

MeJuana I am not sure what you mean by "you dont do this for indoor plants". My issue was conflicting grow room schedules, and my main question was do I give a one time dose of extended light, or darkness. Does it matter?

In the end, I dont think it did. The plant is doing GREAT, ready to be culled (turned out to be a darn male)

Cheers

Sorry... Don't worry about long light hours or long dark hours when moving to flower because I don't and I have never had a problem.
