Hey guys!!
Ladies are currently under 12/12 from 10pm to 10 am.
I'm trying to change my 12/12 light cycle to turn on at 10am and off at 10pm.
Am I dead in the water and have to stick with my original light schedule? Or is there any way I can change this without any problems. +rep reply!!

i think what the OP was asking is it ok to flip the periods, light becomes dark and dark becomes light
i think the usual answer(i haven't tried this) is it's not a good idea, putting light where there was dark is a stress
if it had to be done an extended period of dark, such as 24 hours, then restarting the 12/12 cycle might work
i think this is how you find out if you have hermie traits in the strain

Plants react to "Light" they are OK with more darkness, so 12 more hours of darkness and then light is not a problem.

This is why people worry about a "Light" interupeting the flower period.

I do this because in the spring I will flower during the day, but in the summer I want to flower at night, because of the heat.

Not a problem.

Good Luck :bigjoint:

It is a personal choice. They don't need 24 hrs of light but will grow quicker than in 18 hours. Many people find it hard to accept no darkness so err on the side of 20 hrs dark and 4 light. Best of both worlds eh?

edit.. to be basic about it. light is for growth, dark is for potency. there is no real potency engine going on during veg so we use the light to produce as much growth as possible in our allotted time. For what it is worth, I run 20/4 also. It simply cuts 20% from the electric bill

I had to do this too! Just adjust time by one hr a day....say give 12L/13 D this way it is gradual and will not mess with them but you need to adjust timer every day to insure the time is correct and working. So in 12 days you will be on the time you desire without drastically F'ing the light/ dark schedual. dont want it to go all Hermie an yah!

I had to set my clocks back by an hour once because of a school bus and it never effected the grow. I melted the main powerbussbar in the main breaker box. Luckily the box had another bar but it was on the other side and there wasn't a hole in the panel for it. It took me about 40 minutes to get the system back up, but all of these minor interuptions had no obvious effect on the grow.

Extend the dark period to the new time for the lights to come on and reset the timer for the new schedule. This will not affect the flowering cycle of the plant. This change can be done with one clock change and doesn't have to be stepped up to the new schedule.
