Dude you are thinking so hard it is making you stupid. The resin (trichomes) are the plants sunscreen. The more UVB light you have the more trichomes are produced. However the hps is very low uvb light where a halide has very high uvb light. The light being off in the in the morning and evening will only reduce the amount of uvb available to the plant. Plants dont care if you mimic the morning or afternoon with less light. All the plant knows is that there is less light so it cant photosynthize as effeciently, which translates into slower growth. Plants just need light to grow and the amount of available light dictates how much growth is going to occour, more the better. Good premise but you need to think about all aspects of light before doing something like this. Plants are stupid and easily manupulated.
