Light flowers with sodium good or LED plant lights?
LED lights plant -- all I've seen is that greenhouse
The light effect is similar, but LED more power, can be a long time to fill, so LED more.
High pressure sodium lamp is good. Mercury lamp does not work.A square meter should be 200 to 500 lux, then according to the light effect factors such as distance, lighting, lamp lights to determine how many watts bulbs!
