Doing this can lead to temperature increases. Placing the light close to direct sunlight can also lead to overheating issues. 

Cause #3. Burnout of the Light Source 

Did you know that light sources also have lifespans?

Yes, light burnout is real, and it’s probably one of the reasons why your grow light is not working. Grow lights are artificial lights that require replacement and maintenance periodically. 

Burnout occurs when the light-emitting elements outlive their lifespans or face some form of functionality damage due to aging. 

Other issues, like running the light excessively, are also common. Common signs of light burnout include burning and compromised light quality over time. 

Cause #4. Poor Maintenance 

The lack of maintenance often has catastrophic effects on any electrical appliance – and grow lights are no exception!!

However, your lights’ output can increase significantly with the correct maintenance. One common cause of grow light complications is the need for sufficient cleaning. 

While grow lights offer reliability and durability, you must clean them to ensure they are free from dirt and debris. Plus, a lack of cleaning will also cause the light not to produce the right intensity for growth and photosynthesis. 

Controlling the indoor environment for the grow lights will also be crucial for the bulb’s longevity. For instance, overly humid air can easily lead to bulb failure issues. 

You must ensure the environment sits at the right temperature to avoid causing damage to the bulb. 

One other common cause of grow light failure is poor connections. Any cables or wires in your grow house that need the correct set-up can easily lead to failure. 

Plus, animals like rodents are also notorious for causing such damage, and poor maintenance means that you will never notice these issues at teh right time.

Issues such as incorrect installation or an overloaded circuit can lead to additional light damage. When setting grow lights, place them at the best distance for plants. Putting them too close can lead to burning issues, and too far can lead to developmental problems. 

You must also inspect light regularly for optimal functionality. Part of this process involves replacing broken components, which will help maximize your light output. 

One aspect of installation involves securing the LEDs as required for the walls in your garden. We recommend you evaluate aspects like the mounting pieces for optimal installation results. 

Be keen on loose components or those that are prone to damage. Also, check the cords, and ensure they are well attached to the light fixtures and the power outlet. 

Tip #3. Provide Enough Ventilation

Ventilation is also crucial for the functionality of your grow light – is odd right? Well, it’s true! Without sufficient ventilation, the lights won’t be able to remove enough moisture and heat. 

It’s an issue that can lead to an unhealthy environment for your plants. The lack of ventilation can also cause moisture to accumulate on lightweight components and aspects like the wiring. 

It can eventually lead to issues like short circuits. The heat that accumulates in the grow house might also cause gradual damage to the components of your grow light. 

Tip #4. Use the Right Bulb

Picking the right bulb is also crucial for the performance and success of your grow house. The bulb you choose determines the light your plants will receive. 

There are various bulbs, each producing varied color and intensity levels. So, the best idea pick the correct lights for your grow room. The common ones include:

  • Metal Halide bulbs. These are perfect for when your plants are in the vegetative growth stage. They produce a cool white light rich in the blue leds spectrum. These lights also promote vigorous leaf development and growth. 
  • High-Pressure Sodium bulbs. These are ideal for plants in the flowering stage and for indoor gardens. They produce a strong yellow-orange that’s perfect for flowering purposes. Combining HPS and Metal Halide Bulbs makes high-quality lights for grow rooms. 
  • Floresencet bulbs. These bulbs produce soft light with a low intensity anda high amount in the blue spectrum. These lights encourage optimal leaf growth.
  • LED bulbs. LEDs are increasingly popular because of their energy-efficient benefits. Plus, they also exist in various intensities, spectrums, and colors.
