24 hours of dark best for what? Yes, if growing photoperiod plants you go to 12/12 to stimulate flowering. If growing auotos, stay at 18/6 the entire grow cycle, veg and flowering.

Erratic light cycles for the first week
Any experience with keeping a seedling in 12/12 to begin with, then switching over to 18/6 after the first week? Because I did that this time for tech reasons, and I do wonder if I produced a hermie. My own notion is that it will just set me a week back perhaps. Anyone know tho?

We're Brand New! All of these have been, (we think) Veg. for at least 4 weeks; the two big girls certainly longer. We're thinking about 12/12 a week from today. Any thoughts, comments, input would be welcomed!

Why does this take so long ?
I have three Thai landrace Mekong sativas from Ace Seeds (you can check my diary). Is it normal for them to take this long? I'm in week 16, and there's still no sign of trichomes. One of them is only in the early flowering stage. It seems really weird. Do you guys have any ideas

The FLIP
Getting ready for the good ol’e flip. What do most do you guys do for the light schedule? Is it better say (on/off) 12am/12pm, or 6am/6pm. Worried about daytime activities in that room. My schedule will accommodate just about anything, so what are you thoughts?

How should I trigger flowering?
I am trying to get my plants to flower. I have switched to a 12/12 schedule, but this does not seem to be changing anything. Should I perhaps give it 24 hours of darkness first?
