Cloning for sex

How soon can I force-flower my clones after cutting?

I have cloned my plants to determine sex. Do I need to wait until the clones have roots before forcing them to flower? How many hours of light should I give them daily to get the earliest flowering?

You can force the cuttings to flower as soon as you cut them. These are throw-away clones since they will have already started flowering at only a few inches in height. However, they will start rooting as they turn from vegetative to flowering. If you give them 10 hours of light and 14 hours of uninterrupted darkness, the clones will indicate faster than if given the standard 12-12 light/darkness schedule. Depending on variety and conditions, cuttings will reveal their gender in seven days to two weeks on a 12-12 cycle. On a 10-14 cycle, the time will be reduced by a few days and you'll also save on electricity.
