Hey WW! I kinda have, but not for an entire flowering period...on my last grow I played with the lights somewhat...24/0 of darkness for one day at the beginning of flowering (right when I was switching to "12/12"), then for two weeks I went to 11/13, then 12/12 for two weeks and finally to 13/11 (first number being the "on" time)and then 24 hours of total dark and cut....I would like to tell you I noticed a difference, but I did not notice any at all. Actually what I did was not a valid experiment, because I changed other things in the grow also, like adding molasses. My reasoning for this was I was led to believe that buds need the most light you can get to them ( I also trimmed and staked this grow to get all buds all the light I could, further corrupting the outcome)) and still keep them in flower mode...that's why I was ramping up the on time, instead of your Thai which you are ramping down (your still going down right?) The 11 hours on during flower would seem to contradict what I was told by a very experienced indoor grower that 13 on is better than 12 on, but if your not doing this ramping down on the thai, why would you? Just curious... JC seems to still think buds need the most light you can get on the plants buds during flower and still keep them in flower to maximize bud size. I guess this calls for another experiment....yee haaa!
