    I have just browsed a Dennerle webpage and found info about intermittent lightning. It's here:
    http://dennerle.com/en/products/nano-aquaristic/nano-light
    It claims that lightning in the morning followed by a few hours pause, then afternoon lightning, is the best. Its about 12 hours lightning overall.

    Has anyone tested pr what's your opinion about this?

    The idea is that during the light phase the CO2 will drop, and the pause is there to let CO2 restore to the required level. Not really an issue if you have adequate CO2 supply.

    Attached is a picture of an aquarium that followed Dennerle recommendations (however this aquarium did have adequate CO2 supply).

    In my experience in stead of a pause, a short light boost (10 minutes) several times a day with really low light levels in between, seems to keep internodes on stemplants short but growth rates moderate (less pruning required).

    Dutch scape, dutch furniture :) Nice.
    So, how long are you lighting? And you are switching between two light sources?

    If you do a search on siesta period, you will find diverse opinion on supporting or against split photo periods. I don't know who to believe that split photo periods will promote or confuse plant growth, or will it promote or reduce algae problem. It's all theoretical arguments with no control experiments to prove one way or another.

    Ultimately, lighting to fit my life style matters . I do split photo periods so I can see and feed my fish in the morning, and again in the evening when I am home with 5 hour dark period in the afternoon.
