i have not tried that. i did however just have a situation where the power was off for 6 days and the weather did not allow the plants to be put outside. i had 2 actively flowering and 3 waiting. the two actively flowering were at the end of week 3 when this happened. they were covered in trichs when the lights came back on. they were both good strains to begin with, Jack Herer and GTH#1, so im sure genetics had something to do with it, but it seems to me that the extended darkness contributed significantly to it.
