I will usually take a cutting and start to root the cutting under 12/12 light, then I will put the cutting back under 18/6 light. If its male I usually grow it out for pollen and if its female when it looks like a healthy veg I will spray it with CS then back to 12/12to make female pollen. I only pop a few (3) regs at a time, if you pop several I think its probably faster to just just flip the lights in your grow area and do them all at once, but be careful they can fool you if you make the call too soon.
