Well said ciratac, great job there and pretty correct from my reading. The times taken for a plant to revert back to the vegitative stage can be up to 2 months in my experiences, this shows the level of ethylene is upregulated to massive levels during flowering and that they can gradually drop off when the plants are given a 24 hr cycle or similar but this process is gradual. Even in the presence of 8.5K + light levels I have noticed the same length of time for the change back and baring in mind the flowering period duration of 8 weeks, its no wonder!
