lighting schedule is completely up to the grower. The amount of difference from a 24/0, 20/4, 18/6 is really not that much. When a plant is under a 24/0 the root growth in a 24 hour period is around 28cm, and a 20/4 is around 33cm and a 18/6 light schedule is about 38cm. So the difference between 24/0 and 18/6 is really up to the grower and the effect that it will have on the electric bill. One has to figure out which is best for their situation.

As far as early sexing there is no such thing. You can only tell if its a male or female when the plant has gone into the flower stage. The bud will either grow a flower or what looks like "Ballz" (these are the pollen sacs). You dont want the one with pollen sacs unless you plan on saving the pollen for later and you can see how to do that in one of the FAQ's on the boards.

My best suggestion for you is to go to google, and then do a custom search on these boards for something that you are looking for. I will put a crap load of money down that if you look on these boards, someone has already seen it and fixed it. The problem and solution will be on here. Just take the time to do the searching, your plant wont die in the time that it takes to do the search....I promise it will still be alive when you are done searching.

Good luck on your grow....:thumbsup:
