I agree with OMB that we probably make more fuss out of cloning than we need to. The air in my region is bone dry, so I tend to be very protective of my clones because the dryness is such a stress. I also do believe that intense light is a bad idea right away. The cutting is trying to deal with a lot of new problems and does not have the metabolic flux to handle high light levels. Filtered or shaded light for at least the first few days, then if they're still upright and healthy you can start to give them more. Cervantes also believes in giving plants nutes through the end of flowering, so he obviously has ideas that don't line up with a lot of other people. But as OMB and I have discussed, the best thing to do is experiment. Put some in distilled water, some in tap, and some in pH 5.5 water with 1/50th diluted nutes (the method I use). Put some under bright light and some under filtered, etc. It's the only way to know what really works for your situation. I am now 12 for 14 for my Cannabis clones, which I suppose is pretty good, but obviously my method isn't fool-proof.
