Illusion:
That's good to hear about the other roots on the way. And yes, it might be a good idea at this stage in the game to start slowly bringing the light closer in stages. Watch closely for any signs of heat stress while doing so.

Weedhound (and others):
To scarify, take a clone and an exacto knife, or something really sharp, and scrape off the outer membrane of the bottom 1.25" (roughly) of the stem. Then re-cut the bottom 0.25" off of the clone at 45 degrees. If the cutting was taken from a proper place on the mother, you will see a white bark-like material when you have scraped deep enough. You just go slightly deep, enough to scrape off the outer green membrane. If the cutting is from a real new shoot, there will be no white bark-like material to see, and it's easy to go too deep. It will just sort of turn into mush as you start going to deep, but these usually still hatch roots. Both of these kinds of cuttings will root, but the cuttings from brand new shoots, unless from the main stem, will take up to 2 weeks longer to root, and sometimes have less than optimal scarification results.

Without scarification or 45 degree cut: 2-5 roots
Without scarification but with 45 degree cut: 3-7 roots
With scarification and 45 degree cut: 5-10 roots

I'm just guessing based on experience, but that seems about right.

I highly recommend scarification for your clones. Some people even scarify two sides of the stem, but I have not tried it. Before scarification was popular, some people swore they got more roots by smashing the end of the stem with a hammer. Similar concept I guess. There is a scientific explanation, but if you are interested further there are a couple threads on this forum that go into a little more detail.
