How Far Should LED Grow Lights Be From My Plants?

The process of growing plants from seeds is an exciting idea as LED lights can greatly aid in the process.

LED grow lights supply plants with the light they require to photosynthetic activity. However, a key question for new plant owners is how far away should LED grow lights be away from plants? It is recommended to be sure to keep the LEDs between 12 and 20 inches away of your plant. The distance that the LED lights need to be to plants will be determined by the power of the LED lights.

Distance of LEDs from plants and the wattage of LEDs

Lights with lower wattage (200-399) are recommended to be between 12 and 20 inches away from the plant. As the wattage rises (400-599) it’s distance will increase to 20-27 inches, and the same for other lights, based on how powerful the power is.

Do my lights have too much distance?

When your lights for growing are placed too close to your plant, it may begin to exhibit indications and signs that suggest that this is the case.

Anything less than 12 inches is not close enough the plant. It’s important to watch your plant carefully to ensure it’s receiving enough light every day.

If you notice that your plants are dying, your leaves appear dull or dry or appear like they’ve been burned and you’re unable to move the grow lights farther away.

Light next to pot plants

Edges and tips that are brown on leaves could suggest that the source of light is located too near to your plant and creating damage. It is necessary to alter the lighting according to any signs your plant displays.

If the grow lights are too close to the plants, your leaves could appear scalding or bleached, and may have a light yellow tint.

However, it is crucial to understand that the proper lighting of the LED changes with every stage of growth, and you’ll need to be able to alter the brightness as the plant develops.

The general rule is that seedlings require the lowest intensity and distance from the light source. When they are in the vegetative stage you should move the LEDs closer to the plants.

In the final stage, you require the most intense light. This is merely an approximate guideline, and you’ll have to follow the guidelines given by the grow light’s manufacturer for the most effective outcomes.

It is also important to ensure that you’re paying attention to the other aspects of the care your plant receives and also to ensure that there aren’t any other issues that could affect the health of your plant and its development.

This means that you must ensure that your plant receives the correct amount of fertilizer and water, and that it’s not suffering from diseases or insects.

How far away are LED grow lights from succulents?

The right distance to choose isn’t easy when you are trying to grow succulents using grow lights. If you are too close, the heat produced by the bulbs could cause your succulent to burn.

If it’s too far away, it isn’t enough light that your plant can develop correctly.

In general the LED lights you use are best placed between 18 and 24 inches away of your plant. But in the case of the cultivation of larger succulents, you may reduce the distance accordingly.

The most important thing is to watch your succulents closely to determine how well it’s coping with the growing lights.

It is possible to alter the distance you are using along, based on the growth of your plants and how the plant responds to the lights of your grow.

Every plant isn’t likely to react the same way, therefore it is important to monitor your succulents to make sure they are as healthy as they can be.

It’s also crucial to note that you should not allow the succulents to sit in a single angle of the lighting source. In addition it is important to ensure that you’re rotating your plants every week so that every side receives the same amount of sunlight.

Can light from a growing plant can burn plants?

Yes Grow lights can trigger burning leaves and photobleaching If you’re not careful. But, it depends on the plant as well as the power of the lights.

The proper quantity of sunlight is absolutely essential to plant growth and development as well as its survival. Grow lights are an excellent alternative to make the growing process more efficient, however they could also be detrimental to plants when they are not utilized properly.

For lights with 200-399 watts Do not put them more than 12 inches away from your plant, or you could be at risk of burning your plant. Keeping the lights at the right distance from your plants allows them to absorb the light they require without damaging or burning the plant.

You may be asking, what is the minimum distance to make your lights useless? This will also depend on the wattage you use, however when you’re using 200-399 watt lighting, your plant will not benefit if the lighting is greater than 20 inches from it.

In addition, the length of time the plants are under the grow light is crucial to set the right amount of light. It is recommended to aim for 14-16 hours of sunlight every day, allowing your plants to sleep overnight.

However, this is a guideline only and you may need to alter this based on the type of plant you’re cultivating and the particular grow light manufacturer recommends.

If you’re concerned that your plant will be burned by using the lights you use for your garden I recommend investing in the use of LED lighting or light-emitting diode bulbs. LED lights emit a small amount of heat, which decreases the chance of burning your plants.

In the summary

Grow lights are extremely beneficial to cultivate plants in your home. However you’ll have to keep track of the amount of the light your plants are getting and also the space between the plant and the grow lights as the plant expands.
