Our Cave Junction headquarters is loaded with a full spectrum of lighting to outfit your indoor garden. For the growers who are unable to cultivate their plants outside in the free abundant sunshine, grow lights are necessary to successfully grow indoors. Grow lights take the place of the sun, and power the growth of your plants and their buds. Light is like “food” for your plants, so without a lot of bright light, even a healthy plant won’t flourish as much.

Fluorescent

(You may also hear: CFL, T5, T8, T12)

Popular for propagation, early vegetative growth and over-wintering semi-hardy and tender plants. T5 fluorescents are the most modern type. They are available as single, daisy-chainable strips or in panel arrays. Lamps need to be matched to the fixture (high output (HO) or very high output (VHO)). Different spectral distribution lamps are available for “daylight” and “bloom.” Daylight lamps are used for propagation, vegetative growth and over-wintering. Bloom lamps are commonly used as side-lighting for larger plants flowering indoors.

High Intensity Discharge (HID)

(You may also hear: High Pressure Sodium, HPS, Metal Halide)

The most common type of grow light for general purpose indoor applications-extremely efficient and capable of producing intense light indoors. Metal Halide (MH) lamps give off a bluish spectrum, perfect for vegetative growth. They also contain some ultra violet radiation (UV) which is useful for combating pests, molds and promoting the production of essential oils in aromatic crops. High Pressure Sodium (HPS) emit a yellow / orange light that simulates the fall sun-perfect for flowering and fruiting. Many growers combine HPS and MH lamps to provide a better overall light spectrum for their plants.

Plasma

(You may also hear LIFI, Solar Genesis, Sulfur Plasma, Sulphur Plasma, Light Emitting Plasma, LEP, and Plasma Grow Light.)

A relatively new lighting technology which is still proving to be prohibitively expensive for the vast majority of consumers. Plasma grow lights offer higher efficiency than HID, longer lamp life and less depreciation, and improved output spectrum-especially for vegetative growth.

Light Emitting Plasma Grow Light

Light Emitting Diode (LED)

(You may also hear LED, LED Panels.)

LED technology is perhaps one of the most fast moving areas of lighting with developments occurring on an almost daily basis. Some early panel LED fixtures entered the horticultural industry with grand claims that didn’t match up to reality. The marketplace has now matured somewhat and LED grow lights are finding their place. Many growers use LEDs to supplement the spectrum of their existing grow lights in order to steer plants into generative development (flowering and fruiting).
