Light cycle question

whats up everyone

ive been using the 18/6 light cycle for a month now my plant is around 4 months from seed should i keep it on this for another month? or should i switch to 12/12? the plant is like 24 inchs tall. and how long do i leave it on 12/12 for

is the plant showing sex?? this indicates pre flower. depends on how big you want to grow her aswell when you switch to flower the plant could double to triple in size at 24 inch i would say its ready to flower.

Yeah, if it's 2' tall, it's going to be pretty big when it's finished, I'd flip it to 12/12, now. Then, you leave it on 12/12 til the plant is finished, which'll take at least 8 weeks, probably closer to 10, and possibly 13 or more, depending on strain. In the meantime, read up on "when to harvest" and you'll know exactly when they're finished, when the time comes.
