Weed plants should be about 18-24 inches away from light. If they are too close, the leaves will burn. If they are too far, the plant won’t get enough light and won’t grow as well.
When it comes to growing weed, one of the most important factors is how far your plants should be from the light. If you’re using artificial lights, you’ll need to make sure that they’re not too close to the plants or they will scorch them. The general rule of thumb is to keep your lights about 18-24 inches away from the tops of your plants.
However, this can vary depending on the type of light and the size of your plant. If you’re not sure, it’s always best to err on the side of caution and keep your lights a bit further away.

Is My Light Too Close to My Weed Plant?
If you’re wondering if your light is too close to your weed plant, the answer is maybe. It depends on the type of light you’re using and the stage of growth your plant is in. If you’re using a HID (high intensity discharge) light, like a metal halide or high pressure sodium light, it’s important to keep the light about 18-24 inches away from the top of your plant.
This is because HID lights are very intense and can actually burn your plants if they’re too close. However, if you’re using a CFL (compact fluorescent light), LED (light emitting diode), or other type of less intense light, you can probably get away with keeping the light a bit closer to your plant. Just make sure that the leaves don’t start to turn yellow or brown, which could be a sign that they’re getting too much light.
As for how close is too close, it really varies depending on the type of plant and its growing conditions. So experiment a bit and see what works best for your particular setup.
How Far Should Plants Be from Grow Lights?
If you’re growing plants indoors under grow lights, one of the most important factors to consider is how far away from the light source your plants should be. Too close and they can get burned, too far and they won’t get enough light and won’t grow well. So how do you know how far to place your plants from grow lights?
There are a few things to take into account, including the type of light you’re using (LED, fluorescent, HID), the intensity of the light, and the size of your plants. In general, seedlings and young plants will need to be placed closer to the light than mature plants. And taller plants will need to be placed further away than shorter ones.
As a rough guide, small seedlings may need to be as close as 2-4 inches from an LED or fluorescent light source, while larger seedlings and young plants may need to be 4-6 inches away. For mature plants, 6-12 inches is usually a good range for most types of grow lights. But as always, it’s best to start on the low end and move your plants up or down depending on how they respond.
How Close Should My Light Be to My Weed Seedlings?
Starting your weed seedlings off right is key to having a healthy and successful crop. One of the most important things to consider is how close your grow lights should be to your plants.
You may have heard that you should keep your lights as close as possible to your plants.
This is actually not true! Keeping your lights too close can actually cause problems for your plants. The light intensity can be too much for young seedlings and can damage their leaves.
It is best to start with the light about 12-18 inches away from the top of the plant and then move it closer as the plant grows taller.
Additionally, you want to make sure that you are using the right type of light for your plants. LED lights are becoming increasingly popular for indoor growers because they emit very little heat and use less energy than other types of lights.
However, they can be more expensive upfront. If you are on a budget, fluorescent grow lights are a good option and will still provide enough light for your plants to thrive.
How High Should Led Grow Lights Be above Plants?
If you’re using LED grow lights to cultivate plants, it’s important to know how high above the plants the lights should be placed. Generally, LED grow lights should be about 2-4 feet above the plant canopy. However, the exact height will depend on the type of LED light and the size of the plant.
For example, if you’re using a small panel of LEDs to grow a single houseplant, you’ll want to place the light closer to the plant (about 2 feet above the plant). But if you’re using a large array of LEDs to grow taller plants like tomatoes or cucumbers, you’ll need to place the light higher up (4 feet or more) so that it can reach all parts of the plant.
It’s also worth noting that some growers believe that placing LED lights too close to plants can actually cause “light burn.”
This is when leaves develop brown spots or even turn yellow from being exposed to too much light. So if your plants seem to be suffering from light burn, try moving your LEDs a bit further away.

Grow Light Distance Calculator
If you’re a gardener, chances are you’ve struggled with getting the right amount of light to your plants. Too much light and they’ll get burned, too little and they’ll et yellow and sickly. So how do you know how far away to place your grow light?
There’s a simple way to calculate it, using a grow light distance calculator. Just enter the type of grow light you’re using, the wattage, and the size of your growing area. The calculator will do the rest!
For example, let’s say you’re using a 600 watt HPS grow light in a 4′ x 4′ grow tent. The recommended distance from the top of the plant to the center of the light is 24-30 inches. That means that if you have your grow light on a timer and set it to turn on for 18 hours per day, you’ll need to adjust it so that it’s only on for 12 hours per day during vegetative growth and 9 hours per day during flowering.
Using a grow light distance calculator is a quick and easy way to make sure your plants are getting just the right amount of light!
Grow Light Distance Seedlings
As a general rule of thumb, you should keep your grow light about 2-4 inches away from your seedlings. This will ensure that they get enough light without getting burned. If you’re using a fluorescent grow light, you can keep it a bit further away (4-6 inches).
But if you’re using an HID grow light (like MH or HPS), then you’ll want to keep it closer (2-3 inches). You’ll also want to adjust the height of your grow light as your seedlings grow. Start with the light close to the plants, and raise it up gradually as they get taller.
By doing this, you can avoid stretching and etiolation (weak, leggy growth).

How Far Should Led Grow Lights Be from Plants?
This is a common question that we get asked a lot. And it’s an important one, because the answer can mean the difference between a healthy, vibrant crop and a disappointing yield.
So, how far should LED grow lights be from plants?
The main thing to keep in mind is that plants need light for photosynthesis – the process that helps them convert sunlight into energy. The amount of light that they need depends on the type of plant.
For example, low-light plants like ferns only need about 2-3 watts per square foot, while high-light plants like tomatoes need around 10 watts per square foot. led grow lights provide different levels of intensity (measured in micromoles), so you’ll need to choose one based on the needs of your particular plants.
Once you’ve selected an appropriate LED grow light, it’s time to decide how far to place it from your plants.
A good rule of thumb is to start with the manufacturer’s recommended distance and then adjust as needed based on your plants’ response. If they seem stretched or leggy, move the light closer; if they’re burning or wilting, move it farther away. It’s also important to give your plants some “rest” time each day by turning off the lights for 12-14 hours – this will help them stay strong and vigorous.
We hope this information has been helpful! As always, feel free to contact us if you have any questions about choosing or using LED grow lights.
Conclusion
Most growers agree that the further your weed plant is from the light, the leggier (tall and thin) it will become. The ideal distance depends on the type of light you’re using. For example, if you’re using a 600-watt HPS light, you should keep your plants about 18 inches away from the light source.
But if you’re using a 400-watt MH light, you can keep your plants a bit closer to the light—about 12 inches away.
