I feel like I say it all the time, but I'm no expert.

I did read about the process that causes flowering a few weeks ago (may have forgotten some).

From what I understand. Auto flower plants are (could be wrong) plants that evolved in near equitorial regions where 12/12 is 365 (like Cuba or hawaii).

The internal process of deciding when to flower is a chemical reaction inside the plant. So, a good example would be a 24/7 plant produces NONE of this chemical. Once you move the plant to 12/12, this chemical builds up inside the plant tissues. Once it reaches a certain consentration the plant reacts by making flowers.

So, questions would be is ANY light reaching the plants during lights out? ANY light, be it a red power strip switch that glows, a little light making it through openings in the container, light passing through the container itself or turning on ANY light during the dark time. If ANY light makes it to the plant this chemical depleates before reaching the level needed to trigger the flowering.

Hope this helps. BTW green light does NOT effect flowering. You can buy a light on e-bay that is intended to use in a grow room during lights out. Green just bounces off the plant. ANY other color light will cause you issues.

Hope that helps and Merry Christmas.
