21:36/-/12 light period

im into 5th week of flowering, and they are lookin mint, but i was thinkin of tryin this 21:36/12 light period, and was just wondering if any1 ere has tried it and what they thought of it. just pk'd them. moving towards week 6 so should really be getting ready to flush, will this light cycle delay me? should i have started it earlier? and has any1 actually tried it? many thanks to all replies...
