I use the shade of my house as natural light deprecation. I notice this effect on plants that are shaded earlier in the day than those that continue to get sun later in the day. I move my plants around until I hit the sweet spot.
I have some Cantaloupe that is shaded early vs late sun Cantaloupe; time difference of about 3 hrs and 2 weeks flower time. Shaded plants taking the lead. Doing this gives me a chance to test smoke to get the later plants perfect.
As far as faster or better bud development is concerned I don't know. I do know that the plant I have been blooming has better bud growth under 1k vs 2k lights.
I love to experiment, so I will try to figure out a test and a way to quantify the results. The plant is very, very easy to manipulate; to me that is what is so cool.
