The quality of a grow light can be understood by looking at the spectrum of that light source. Natural sunlight is intense and has a broad, balanced spectrum. Indoor plants require the same high intensity and broad yet balanced spectrum.
First Steps: Always Begin With the Following Disconnect main power whenever working on any electrical device. For additional protection you can also disconnect your fixture cord from your ballast (if so equipped). Allow sufficient time for the lighting system, lamp, and ballast to cool down prior to handling. Refer to the product manual or lamp…
High Intensity Discharge lights have been the backbone of the indoor growing industry since its inception.
Too many indoor growers are using the same lights that are used to illuminate office and other work spaces. Plants need different light quality.
A ballast is an electrical device needed to operate HID (High Intensity Discharge) lamps (light bulbs). Examples of HID lamps are Metal Halide and High Pressure Sodium (HPS).
In order to optimize your grow lighting, the three elements of a system need to work together: lamp, ballast, reflector.
