How To Choosing The Best Grow Lights For You

Do you plan to grow your own vegetable and flower seedlings this year? The biggest advantage of growing plants indoors is that you can replicate optimal lighting conditions for your plants and control them as you see fit. When growing outside, however, you must rely on the meteorological conditions in your area. On the other hand, you might find it difficult to shop for grow lights for indoor gardening.


When navigating the best grow light product possibilities, you may encounter some unfamiliar terminology. But don't be put off by this. You simply need to learn a few basic terms when selecting a grow light system for your indoor garden. In this post, we'll show you how to pick the best grow lights for your indoor grow system.


Light begins to play an important role in the growth and health of seedlings once the seeds germinate and the first "real leaves" emerge. Photosynthesis is the process through which plants use sunshine to make their own nourishment. Indoor gardening success is mainly dependent on grow lights that closely mimic sunshine in order to stimulate photosynthesis without producing too much heat. Your seedlings will thrive in the presence of a high-quality, energy-efficient full-spectrum light that is evenly diffused across your growing area.


 Best Grow Lights

Here are some basic terms for you to choose the best grow lights:


Correlated Color Temperature (CCT)

CCT, which is measured in Kelvins (K), specifies the hue of the light source as warm (yellows) or cool (blues). Because natural light has a CCT rating of 6500K, a light bulb with a rating close to this value is suitable for grow lights.


Color Rendering Index (CRI)

CRI measures how well a light compares to visible sunshine. The maximum CRI rating of 100 corresponds to natural daylight. Good full-spectrum lights for indoor gardening have a CRI rating of at least 85, preferably 100.


Remember to look for the Correlated Color Temperature (CCT) and Color Rendering Index (CRI) information on the product label to identify a high-quality full-spectrum light. It’s recommended to purchase enough fixtures to spread light throughout the space adequately. Seedlings along the perimeter should receive the same amount of light as those in the centre in order to grow.


Now let’s look at some key considerations when you choose the best grow light for your indoor grow:


Efficiency vs. Energy Expenditure:

While more power means more output, it also means higher electricity expenditures. The most commonly used grow lights range in power from 400W to 600W, with associated ballasts. In general, LED grow lights produce the same amount of energy at a significantly lower wattage level.


Light Spectrum:

The light spectrum will differ based on the stage of development of a plant. For example, marijuana plants require blue light during the vegetative stage and red light during the flowering stage. Many growers will replace the light bulbs in their cannabis plants at various stages of development. Blue light throughout the growth phase will always result in larger plants; nevertheless, some gardeners choose to use the same grow lights throughout the cycle, varying only their intensity. While this is possible while working with sodium lights, it is not recommended when working with fluorescent bulbs. With the flip of a button, most modern LED lights will allow you to switch between spectrums.


Temperature vs. Space:

The higher the wattage, the greater the amount of heat. This is unlikely to be an issue if your grow tent or room is large, but if it is small or you live in a hot climate, you may need to invest in fans to help you control the temperature.

Because plants require a particular quantity of light, the distance between plants and grow lights matters. That distance is determined by the intensity of the light provided by the light source (incandescent, fluorescent, or LED).

It is critical to have adjustable light fixtures so that you can alter the height above your seedlings as they grow. If you notice browning on the leaves and leaf edges, it could be because your lights are too close to the plants. If your seedlings appear leggy, your lights may be set too high. Follow the height guidelines provided by the lamp manufacturer for best performance.


Duration of Light Exposure

Indoor plants demand more light each day than outdoor ones. When cultivated under artificial illumination, the majority of edible species should receive 14 to 18 hours of light every day. However, avoid the impulse to leave the lights on all the time; plants require at least six hours of darkness per day to thrive.

Plants require periods of darkness, so don't leave the lights on all the time. Most hardware stores sell affordable programmable timers. Furthermore, your seedlings may suffer if exposed to excessive heat, so use light bulbs that do not dissipate excessive heat.


Understand the main types of grow lights and choose the best one for your needs:

Fluorescent Grow Lights (CFLs) with high CCT and CRI ratings have proven to be effective for seedling growth. On the other hand, T5 fluorescent HO (High Output) lights emit heat that can harm your seedlings. A simple, affordable thermometer hung at canopy level will aid in temperature monitoring.



LED grow lights, while more expensive, have higher CCT and CRI ratings, are more energy efficient, and last longer than alternative lighting technologies. They are worthy of consideration.

Prior to the arrival of LED grow lights, High-Intensity Discharge (HID) was the dominant choice for large indoor plantings. Although HID grow lights are extremely strong, they are expensive, inefficient in terms of electricity usage, necessitate specialized illumination, and generate a lot of heat. Despite this, they are still widely used and quite effective in indoor gardening. HIDs are an excellent alternative for growing large plants such as tomatoes or lemon bushes since the light penetrates the foliage more deeply than other types of bulbs.


The use of grow lights has transformed plant growth. In areas with long, gloomy winters, such as most of Canada, relying just on sunlight to grow plants is not always sufficient. When selecting the best grow lights for your plants, keep the variables listed above in mind. Good lighting is essential for growing seedlings inside. With a little preparation, you can kick off the gardening season with a bang!
