Not Understanding LED Tape?

[naoki]

Is giant motorized mirrors attached near the roof (of the main house) a possibility? The angles of each mirror moves with the sun movement, and reflect into the shade house. Initial cost may be high, but the maintenance cost could be lower. If you are going to use artificial light for such a big area, you need to pay a lot of electricity. Since you are in warm region, it seems to be more economical to use the natural light source.

Alternatively, can you use light diffusing material as the roof? I don't know much about this topic, but here is a related topic:

If you want artificial light, isn't HPS better for this kind of application? Efficiency of HPS (in terms of photosynthesis) is similar to the top-end LEDs and higher than low-end LEDs. Here is the data:
