The right kind of light can make the difference between a healthy and thriving garden, or a lackluster and dying one. The challenge is that there are so many different factors to consider when you’re choosing the right light for your plants: What kind of lights do you need? How much of each? Where do they go? Will they grow without them? In this article, I will explain which spectrum is best for vegetative growth and how to use it to get the most out of your plants. I will also discuss why some lights are better than others, as well as how much light you need in order to grow healthy plants.
What is the best light spectrum for vegetative growth?
Light spectrum is a measurement of how much light is being emitted in different wavelengths, or colors. The best light spectrum for vegetative growth (which comes from the blue end of the spectrum) is between 400 and 600 nanometers, but most growers choose lights that emit around 430 nanometers.
These are the different types of light you can use.
- White light
- Red light
- Blue light
- Purple light
- Green light
- Yellow light
- Orange Light, Amber Light, Violet Light

What light spectrum do I use?
There are two options for your growing lights: cool white or warm white. While you may want to grow with the same type of light all the time, it’s actually better to mix them up throughout the day and night. Here’s why:
- During the day, you’ll want to use cool white lights since they provide enough energy for your plants’ photosynthesis process, which is necessary for root growth and overall health. Think about this like a sunrise—it’s not as bright at first but gets brighter as more sunlight hits your plants. This also helps avoid sunburn damage from too-bright lights that could happen if using all-day warm white lights during their peak hours of sunlight exposure (e.g., noon).
- At night is when you should switch over to warmer hues because these don’t burn leaves from excess heat exposure during nighttime hours when temperatures drop lower than they do during daytime hours—especially since many growers choose greenhouses with artificial cooling systems installed inside them so there isn’t any sunlight coming through windows either!
When should I use cool white and warm white bulbs?
- Cool white bulbs are used during the day. They have a higher color temperature, which means they emit more blue light than warm-white bulbs.
- Warm white bulbs are used at night. They have a lower color temperature, which means they emit more red and orange light than cool-white bulbs.
- Warm white is often used in greenhouses because plants need less intense blue light when photosynthesizing under bright sunlight conditions (see above).
- Cool white is usually recommended for indoor use, particularly in plant growth chambers or other areas where you want to encourage vegetative growth (think: stem length).
Which spectrum do I use at night and during the day?
The best spectrum for vegetative growth is cool white light at night and warm white during the day. Cool white lights are typically around 6500 Kelvin, while warm whites (or incandescents) are 3000-4000k.
Which spectrum do I use in my greenhouse?
While it may seem like the obvious choice to use a cool white bulb during the day and a warm white bulb at night, this isn’t always what your plants need. In fact, indoor growers should be careful not to use too much of one type of light at once. For example, if you were to leave your grow lights on all day with only warm bulbs in them, this could cause photosynthesis problems for your plants as they won’t be able to absorb enough CO2 gas.
Similarly, leaving grow lights on when they aren’t needed can also take away from their effectiveness because they will eventually burn out if left unattended for too long (typically within 6 months). So unless you plan on using this system for an extended period of time without turning off your lights or replacing them altogether with new ones then I wouldn’t recommend doing so!
Use the right sort of light where you grow your plants to get the best possible results
The right kind of light can make a huge difference in the health and well-being of your plants. When it comes to getting a plant to grow, you need to make sure that it has just the right spectrum of light.
The best way to do this is by using LED lighting. This sort of lighting will be able to give you an exact color range that will allow your plants to thrive.
The best way to make sure your plants have the light spectrum they need for healthy growth is to find out what type of plant you’re growing and where it needs to be grown. For example, in an indoor garden, you might use warm white bulbs during the day and cool white ones at night. In a greenhouse or outdoors, red wavelengths are more effective at promoting photosynthesis than blue so that’s probably what you want most of all unless it’s summertime when blue would help keep things cool enough during hot weather periods.
