In the end, we can conclude that a high-quality grow light should include a white spectrum. That is why some of the latest produced grow lights are starting to incorporate it in their full light spectrum.
But are white LED grow lights good for growing? In this post, we look at what exactly white LED lights are and try to establish their effectiveness when it comes to indoor plant growth!
A common debate subject for growers recently has been the effect of white LED lights on indoor cultivation. While they have traditionally been used for lighting purposes, white LEDs can actually be employed as an indoor grow light as well.
White, Blue, and Red Wavelengths…Not Just White!
The role of UV diodes is to enhance the production of resin to form more trichomes. This results in healthier plants with better flavor, aroma, and potency. Meanwhile, infrared assists in flowering and stem strength.
Before we answer this question, it is important that you first understand what white LEDs offer. While most indoor cultivators are conversant with the advantages of using purple grow lights, white LEDs are rarely considered.
Understanding White LED Lights
If you are searching for the best cheap LED grow light you can use to grow cannabis and other small plants like flowers or seedlings, a great option for you would be the Sansi 40w daylight LED bulb.
On the bright side, you won’t have to install as many white LED lights in your grow room. They are more ideal for your eye color needs when used alone, and not for plant growth!
Selecting the Wrong Light Spectrum
In order to grow efficiently, plants need different types of light for each growth stage. With full-spectrum LED lights this is easily achievable, but if you select the wrong setting, the plant will not develop well. You should also take into consideration the conditions in the room where you’re doing the growing. For example, plants benefit most from light in the blue spectrum when they’re in the vegetative stage of growth. That means that if you set the light to emit light in the red spectrum, you will only be hindering the plant’s growth.

Grow lights are a great tool for making the growing process more efficient, but they can also be harmful to the plant if not used correctly. Here are 10 things you should avoid doing when using LED and other types of grow lights.
Overheating the Plants
You will know the plant is taking too much heat if the leaves that are closest to the light start turning brownish. The first signs look like thin outlines on the outside of the leaves, so if you catch this quickly you will have a chance to avoid further damage. If some of the leaves start curling up, it might also be a sign that the plant is too close to the light. Good ventilation usually also helps with this issue.
For people who use cannabis derived products on a regular basis, it is very tempting to try growing the plant at home. The benefits are quite obvious: the cost is drastically lower and there aren’t any hassles related to the actual purchase of medical marijuana.
Many people all around the world grow cannabis at their homes, be it for recreational or medicinal purposes, and while some of them do quite well and manage to produce a good product, for others it doesn’t work so well – their plants wither quickly or produce insignificant yields.
Forgetting to Adjust the Lights
Many people forget to adjust the height of the lights as the plants grow bigger and end up with burnt leaves. Another important thing is to occasionally rotate the pots in order to prevent the plants from leaning towards the light too much.
Overwatering When Switching from HIDs to LEDs
Regular HID lights produce a lot of heat and generate lots of infrared light. This dries out the plant and the soil and results in the need to water the plant more often. However, LED lights generate no infrared light and don’t emit nearly as much heat, so there is no need for abundant watering.
And the efficiency has continued to increase to the point where white LEDs are now the most efficient lights on the market. Especially ones with added colored light, but we’ll get into that in a minute.
If you look at the spectrum of a popular white LED grow light, you can see that today’s white LEDs give you a true full spectrum light with output at every wavelength.

How do you alter the color temperature of a white diode?
Since only part of the blue light is converted (as opposed to the whole UV light), this type of diode is much more efficient.
What Is The Wavelength Of White LED Diodes?
Doesn’t that mean that white light is less efficient than a “blurple” LED?
