![]() You can also fine-tune the colour wavelength put out by the bulb, so a single LED bulb can be made to produce both red and blue wavelengths for optimal growing, negating the need for multiple light bulbs. Thanks to their energy efficiency, longevity, and the low level of heat they emit, LEDs have quickly become a popular light bulb option for growing plants. Speak to a gardening expert about which type of bulb would work best with the plants you are growing. For the best results, make sure they offer full spectrum lighting. PRO TIP: If you just have a few plants and don’t want or don’t have the space for a full grow lamp setup, compact fluorescent (CFL) bulbs can be used as grow lights as well. However, if you are very serious about indoor growing, you will want to select a clearly-labelled full spectrum bulb, which provides the closest facsimile to the sun.įull spectrum lamps are best for plants that need lots of light, such as: ![]() If you’d prefer not to have the ambience from the purple-pink tones of a red/blue light, daylight coloured bulbs with a high correlated-colour temperature (CCT) rating can also provide you with enough lighting to facilitate growth. Alternatively, you can select a full-spectrum bulb, which most closely resembles the sun. You may need to do some research or experiment with how much blue vs red light each plant type needs to see optimal results. What works for one type of plant will not necessarily work for another. It’s also important to remember that different types of plants require different ratios of red to blue lighting. Blue light – “control how plants respond to a daily cycle of light… tell plants when to flower.” ( McCallister, A.Red light – “tell plants how many leaves to make and how big to make them”.The different wavelengths of light affect plants in different ways: The colour designation refers to the visible light wavelength. PRO TIP: “Red” or “blue” light refers to more than just the colour of the light bulb, though you may find some of the light bulbs do give off red, blue, or pink illumination. Red and blue light are best paired together, as they provide more even growth levels when combined. Most grow lights are either full spectrum, which means the light they emit spans the entire electromagnetic spectrum (similar to the sun), or they provide particular tones that plants find the most useful for growing-specifically red and blue light. ![]() Indoor grow lights will supplement the natural light you do receive, giving your plants the boost they need to photosynthesize. If you don’t receive a lot of natural light, don’t worry-your indoor plants can still thrive.
