Metal Halide (MH) vs. High Pressure Sodium (HPS)
Metal Halide (MH) bulbs are biased in the blue wavelengths which promotes vegetative growth in plants. High Pressure Sodium (HPS) bulbs are biased in the red wavelengths which promotes blooming or flowering in plants. While it is possible to use HPS or MH bulbs alone for the full-cycle of a plants life, it is recommended to use both MH and HPS bulbs during your grow cycle for best results.
Sun System 15' Vertical Lamp Cord with Mogul Base Socket
Use this socket to replace a broken one or as an inexpensive alternative to a reflector. Works great for supplemental lighting. Plugs directly into the ballast with no wiring necessary. Includes hanging hook. Learn more about this lamp cord here.
