Here's where serious indoor growing starts. At Planet Natural we offer a large selection of high-intensity discharge (HID) indoor grow bulbs, both Metal Halide (MH) and High Pressure Sodium (HPS) lamps. All have been manufactured using the latest technology and are designed to produce stronger plants and higher yields. Or you can customize your light source with flexible-use HID conversion bulbs that make it possible to interchange MH and HPS bulbs from your MH or HPS ballast.
