How Growlights Work
Growlights mimic the sun’s photosynthetic spectrum and provide plants with artificial sunlight. Growlights are different from standard light bulbs because traditional bulbs do not emit the particular wavelengths of light that plants use to create energy. Plants use blue, red, and green light for photosynthesis. Many LED full-spectrum lights have peaks in these wavelengths that correspond with important functions and aspects of plants, such as Chlorophyll A and B, Chlorophyll Synthesis, Carotenoids, Carotene, and far-red Phytochromes. Blue, red, and green light must work in combination for a growlight to render the best reaction from a plant. Blue and red light are the most efficient for promoting photosynthesis, but green light is also important for driving CO2 fixation on the lower side of leaves. Full-spectrum white growlights provide all three hues in the appealing white color we are accustomed to seeing in our homes. This allows for a natural integration of growlights into home decor!

Popular grow light choices include:- Fluorescent lights
- HID, MH, and HPS lights
- Red/ blue LEDs
- White, full-spectrum LEDs
Fluorescent Growlights
Fluorescent lights are useful for all indoor plants but most popular for small plants and seedlings. Fluorescent bulbs are fairly cheap to purchase but tend to have a short lifespan, meaning that you will make repeat purchases to maintain this growlight. Fluorescents are very effective for growing leafy greens and plants in their vegetative stages but are less fitting for encouraging flowers and fruit growth. Fluorescent Lights by Adam King
Pros
- Low initial cost
- Available in all sizes Short lifespan
Cons
- Short lifespan
- High power consumption
- Undesirable aesthetic appearance
HID, Metal Halide, and HPS Growlights
High-intensity discharge lights (HID) such as Metal-Halide (MH) and High-Pressure Sodium (HPS) lights are typically used in large commercial grow operations. These bulbs use the most electricity and produce the greatest amounts of light and heat, resulting in high electricity bills. HIDs are typically used to grow large batches, such as heavy-flowering and fruiting plants, indoors. Pros
- Medium initial cost
- High output strength
- High crop yield
Cons
- High power consumption
- High heat production
- Unpleasing appearance
Red/Blue LEDs
Light-Emitting Diode (LED) lights have recently gained popularity because they emit the ideal photosynthetic light spectrum for plants while using little electricity. Although these LEDs may be the most efficient growlight, their display blue and red lights can be distracting in an aesthetic setting. Pros
- High output strength
- High crop yield
- Low power usage
Cons
- High initial cost
- Red/blue light display
White/Full-Spectrum LEDs
White, full-spectrum LED grow lights complement the home and although you can only see the white light, they project blue, red, and green light waves to maximize photosynthesis. While they are not ideal for larger crop-growing operations, they allow efficient growth of any houseplant without sacrificing interior design aesthetics. This type of grow light is ideal for growers who want to seamlessly integrate greenery into their home decor. Pros
- Low power consumption
- High CRI Value (Museum-quality lighting)
- User-friendly
- Long lifespan
Cons
- High initial cost
- Not suitable for large-scale growing
