Flowering

Hey,

I was wondering after I do the photoperiod for 12 hours, do I put the light back on after 12. And change the cycle ffrom 18/6 to 12/12?

I would either gradually increase your dark-period (or decrease your light-period) from 18/6 to 12/12 by 30-min. to an hour a night. For example, my plants have been on 18/6 since sprouting and there currently 44 days old. I plan on adjusting the light ratio by 30min. a night, once I get to day 60. So I will get to 12/12 by day 72. Hope this helps!

IMHO (read more, trust your own will)

going straight into the 12/12 is fine.

the lesson I'm learning now is to use less time in the veg state. Keeping them smaller may reduce the overall harvest, but not enough to warrant the extended light, feed, and raw time factors.

18-24h vege, 12-14h flower ( depends on strain ) but any plant will flower 12/12
first 1-3month vege and then 2-3month flower. take your own will and fly !
