Best full-spectrum lights for indoor gardening have a CRI rating above 85, but the closer to 100, the better. Be sure to buy enough fixtures to evenly distribute the light over the entire area. For seedlings along the perimeter to thrive, they should receive the same amount of light as those in the center.
Detailed Instructions for Choosing a Full Spectrum LED Grow Light：
When browsing the many options for lighting products, you may come across confusing terminology. Don’t let this scare you. You just need to know a few basic principles when choosing a grow light system for your indoor garden.
Once the seeds have germinated and the first “true leaves” appear, light begins to play a vital role in the growth and health of the seedlings. Outdoors, plants harvest energy from sunlight to produce their own food, a process called photosynthesis.
Successful indoor gardening relies on grow lights that closely mimic sunlight to trigger photosynthesis without generating excessive heat. Your seedlings will thrive under high-quality, energy-efficient, full-spectrum light that is evenly distributed over your growing area.
To determine high-quality full-spectrum light, check the Correlated Color Temperature (CCT) and Color Rendering Index (CRI) information on the product label.
CCT is measured in Kelvin (K) and describes the color of a light source in terms of warm (yellow) and cool (blue) colors. Natural light has a CCT rating of 6500K, so bulbs with a rating closer to 6500K are ideal for grow lights.
CRI is used to assess how well light compares to visible light. A maximum CRI rating of 100 corresponds to natural light from sunlight. A good full-spectrum light for indoor gardening has a CRI rating above 85, but the closer to 100 the better.
Be sure to buy enough light fixtures to distribute light evenly throughout the area. For the perimeter seedlings to thrive, they should receive the same amount of light as the center seedlings.
Plants need a certain amount of light, so the distance between plants and grow lights will vary. The distance depends on the light intensity produced by the light source (incandescent, fluorescent or LED).
It’s important to buy adjustable light fixtures so you can change the height above your seedlings as they grow. If you see browning on the leaves and leaf edges, this could be a sign that your light is too close to the plant. On the other hand, if your seedlings are thin, your lights may be too tall.
For best results, follow the height recommendations provided by the lamp manufacturer.
At 65 to 75 degrees Fahrenheit, your seedlings need 16 to 18 hours of light per day. You can find inexpensive programmable timers at most hardware stores. Plants need a period of darkness, so don’t leave the lights on constantly.
Also, your seedlings may suffer if exposed to a lot of heat, so it’s important to choose bulbs that don’t give off too much heat.
Fluorescent grow lights — T5 with high CCT and CRI ratings — have been proven suitable for growing seedlings. However, the heat from T5 HO (high output) lights can damage your seedlings. Hanging a small, inexpensive thermometer at canopy level will help monitor the temperature.
Although more expensive, LED grow lights have better CCT and CRI ratings and are more energy efficient and durable than other lighting technologies. They are worth considering.
Good lighting is essential for growing seedlings indoors. With a little homework, you can start your gardening season!
