Can You Change the Lights During Grow?

Can you change the lights during grow

Before you begin your grow, you’ll need to know what kind of light you’re going to use. Most grow lights have recommended distances and intensities, so follow those guidelines if you’re growing plants under a grow light. If you need to make changes to the lights, you should make them gradually over several days. Doing so will prevent your plants from becoming stressed by sudden changes.


With LED lighting, you can control the spectral output of your lights and change them throughout your grow cycle. LED lights respond to variations in the canopy of your plants and other factors, such as latitude and other grow lights in your grow room. By making these changes, you can tailor your grow light to match the wavelengths of light your plants require.

LED grow lights come in a variety of colors. Some are blue and green-based, while others have red or ultraviolet-light spectrums. It is important to choose a specific wavelength for your plants, as different wavelengths have different effects on different plants.

Incandescent bulbs

Plants require certain color spectrums to grow properly. These wavelengths fall in the blue and red light spectrums. However, regular incandescent bulbs fall more heavily into the yellow and green spectrums. Additionally, they generate a lot of heat, which can be harmful to plants when placed close enough. LED and fluorescent bulbs incorporate a variety of different wavelengths into their lights. Both can be adequate for some situations, but grow lights are specifically designed to give plants the proper color balance and intensity.

Traditional grow lights are less expensive at first, but they require more maintenance and bulb replacement. They also have limitations when it comes to lighting controls. You can buy fluorescent, LED, or high-intensity discharge (HID) grow lights, but you should choose the right one for the type of plants you want to grow.

Dimmable LEDs

When it comes to lighting your indoor grow room, dimmable LEDs can be a valuable tool. These lights are dimmable and can integrate with your climate control and other growing factors to give your plants a more ideal growing environment. They can also be connected to a wireless mesh, which allows you to control the lighting from a mobile phone or other device. These features can help you maximize your yield and increase the quality of your crops.

Dimmable LEDs can also help you grow multiple types of crops. This is because different crops require different levels of light. Some are sensitive to high light levels, while others require low levels. Because of this, non-dimmable LEDs can only be used for one type of crop. However, dimmable LEDs can help you grow more than one type of crop, and even the same crop in different stages of growth.

Spectrum of light they emit

Plants require different spectrums of light at different stages of their growth. For example, early growth stages require more blue light, while late flowering stages require more red light. A common reference for the ideal spectrum is the McCrees action spectrum. However, each plant has its own unique response to light.

Plants can absorb specific wavelengths of light and are sensitive to those wavelengths. The PAR range includes 400 to 700 nm, and different wavelengths can trigger different responses in plants. For example, red light may increase plant size, but it can cause the plant to become stretched.

Maintenance required

Proper maintenance is critical for the health of your plants. Clean your grow room on a monthly basis to keep your grow room free of debris. You should also check your grow lights, especially those with LED lighting. If you find that they have failed to work, replace the bulbs. You should also inspect your plants every now and then to avoid mold growth and ensure the long-term health of your crops.


Changing lights during a grow cycle can be a very expensive proposition. While plants need light to survive and thrive, the type and intensity of light you choose can greatly impact your plants’ growth. It’s best to consider your lighting needs before investing in a growing system. Changing the light intensity during a grow cycle can save you money in the long run, and ensure a high-quality product.

Electricity rates can fluctuate, depending on how often you change lights. You can also choose to use LEDs, which are more efficient than incandescents. An LED grow light can save you anywhere from twenty to thirty percent on your electricity bill.
