There is a way to have a double lighting advantage when hydro growing marijuana. This is to use both the metal halide lighting and the high sodium.
The trick to this to save money is to buy the lighting fixtures and then buy both bulbs, which can use the same fixture.This allows the hydro grower to change only the bulbs instead of just having one type of lighting for all the marijuana growth stages. This is because each of these types of lighting emit different spectrums that the plants need.
It is easy for the hydro grower to change the light bulbs when needed for each growing stage, since the metal halide is best used when the marijuana plants go into the flowering stage. The high sodium lighting is able to provide the same types of rays as the sun and heat when the marijuana plants are in the growth stage.
