FIRST GROW

You can grow on a 12/12 "flowering" lighting cycle from seed! Look up "12/12 from seed". A cannabis plant cannot enter flowering until it has matured, which usually takes 3 or 4 weeks after it sprouts. After that, you can flower whenever you want! In fact, auto-flowering strains usually begin flowering automatically around 4 weeks regardless of the light cycle. Just remember that a cannabis plant may stretch out to 2x its current height, so make sure you do it with a plan. Don't end up with a 10 foot tall flowering plant in a house with 8 foot tall ceilings LOL It's also extremely important that during those 12 hours of darkness, the plant remain in darkness. Any interruptions can bring it out of flowering.

Flip her! She gonna be huuuuuuuge

You can flip her when ever you want. It really depends on your space and what yields you want to achieve. Be aware that in flower it is possible the plant doubles or almost triples in size. So it is all up to you. Good luck. Hopefully i could help. Cheers
