I believe the plant grows a more extensive root system with age. In my last post in the root development thread are side by side pic's of a 4, 5 and 6 week flowering plant's root system.
There is a dwindling light, as soon as we put them in the dark. The trich's are a reflex to this. I don't believe the dark is actually needed, merely a certain level of low light for a certain amount of time. Once this level is reached, the plants respond by producing the trich's throughout the dark period in preparation for the sun (which is much less intense during the flowering weeks).
