you could, but havesting will be a pain as you need to keep as much of the plant as possible. after your havest and turn the lights back to 18/6 or 24/0 the plant will stress the shit out and take 2-3 weeks to start growing again. it might turn hermi from the stress as well so taking clones before you know your plants sex is risky.
taking clones from a stressed out plant will also be harder as it takes enough stress to root a cutting anyway.
never done it but thats my understanding of things.
