But anything short of a pitch black dark cycle with no light pollution for the duration will suffice for photoperiod strains. Cannabis plants can handle this. High pressure sodium or hps grow lights are far more efficient than other forms of hid.

They emit a gentler yellow light that cannabis prefers when it is in the flowering stage. They do not produce the correct spectrum of light to grow plants. The light that it produces falls into a perfect range of the color spectrum for the growing phase of cannabis.

In particular it s good for producing foliage.

Metal halide grow lights produce light by arcing an electric current through mercury gas mixed with some sort of metal iodide such as thallium thorium or sodium.
