Clip-on Red/Blue LED Grow Light for indoor plants

Our red/blue grow light gives your plants the extra light they need to thrive, right where you need it.

Whether your space is on the dark side, or the winter months are leaving your plants short on sun, this light helps fill the gap.

The light heads are flexible, so you can angle them whichever way your plants are growing.

If your plants could do with a little more light, this is an easy place to start.

This indoor unit has a robust metal build and quality Light Emitting Diodes (LEDs) that emit light mainly in the blue and red wavelengths. Both matter for healthy growth: blue light supports chlorophyll production, which drives photosynthesis and healthy leaf and stem growth, while red light encourages germination, root development and bulb formation. The result is an efficient light that gives your plants the wavelengths they use, and little that they don't.

Light output concentrated in the blue (460 to 470nm) and red (620 to 630nm) bands.

Note: the light does not come with plants or a pot.

setting up your grow light

It arrives fully assembled. Clip it onto a table, shelf or other surface, then arrange the lights over your plants.

positioning your grow light

Keep the light at least 10cm from any leaves so they don't scorch.

• Set the timer to match your plant and its spot:
  • 12 hours for plants in low-light spaces
  • 9 hours for spaces with indirect natural light
  • 3 hours for plants in bright, naturally lit spots
• Think about where your plant comes from, too. A low-light houseplant may need very little extra light, while something like basil will want plenty.
• Start dim and build up to the brighter settings over a few days, so your plants have time to adjust. If leaves start to brown or look scorched, lower the intensity.

are these lights suitable for soil plants too?

Yes. The light simply gives your plants the wavelengths they need to grow, so it works just as well for hydroponics, aquaponics, or soil-grown gardening.

does the light produce uv light?

The LEDs give off a very small amount of UV light, less than most household bulbs, and nowhere near enough to harm your plants.

how are grow lights different to normal lights?

The short version: grow lights are tuned to emit the wavelengths plants need to grow. For the longer answer, our guide on what type of light plants need to grow is a good place to start.

what's the best way to measure the effectiveness of a grow light?

Grow lights differ from normal household bulbs because they emit the wavelengths plants need, measured on the PAR scale. Most household lights, by contrast, are optimised for the visible spectrum. It helps to know the main measurements:

• Lumens: the brightness of light within the range the human eye can see.
• Watts: purely a measure of energy consumption.
• Kelvin: the "temperature" of light, for example bluish or reddish.
• PAR: photosynthetically active radiation, the wavelengths plants need to grow.
• PPFD: photosynthetic photon flux density, the intensity of light in the range plants use.

what's the main difference between the full spectrum and purple grow lights?

The main difference is how the light looks. This light uses red and blue LEDs, so it glows purple. Our clip-on full spectrum grow light gives off a warm white light that looks more natural in a living space, while still delivering the wavelengths plants use.
