How to Avoid Burning Your Plants?

My plants seem to have been burned by light or heat. I am very concerned about the health of my plants, so I want to know how to avoid burning plants so they can thrive.

Here are some steps you may do to make sure your priceless plants are spared from any burn.

Choose Cool Burning Lights

First, avoid utilizing HID lights if at all possible. You can utilize fluorescent lights to grow little plants.

The risk with LED grow lights is also rather low. But it’s not zero either. If an LED grow light is hanging too close to your plants, it could easily burn them. Don’t let manufacturers who boast that their lights don’t emit heat fool you into thinking LEDs are safe.

Keep Your Lights Sufficiently Above the Plants

You should keep the LED lights a significant distance away from the plants, even if they burn more slowly. Start with the recommended hanging height from the manufacturer and monitor your plants from there. Keep a watch on everything and make adjustments if necessary.

If you use hot lights, such as HPS or MH, keep them at least 12 inches away from your crops. Most likely more.

When hanging your grow lights in a grow tent, we always advise using ratchet hangers with customizable lengths. As your plants get larger, you can then simply change the height of your lights.

You can make an exception during germination because you need the added heat to help your seed grow into a seedling. This stage can benefit from proximity and heat. When a seedling emerges, it’s necessary to move the light source farther so as not to burn the delicate leaves. For seedlings, most growers choose fluorescent lights or LED lights.


Install temperature sensors and light timers on your lighting system so that the lights will automatically dim or turn on when you want them to and that the A/C will switch on when the temperature reaches a certain threshold.

Run your grow lights at night rather than during the day if you live in a hot area. The ideal time to use grow lights is typically during the day, although this is not always the case. Cooling can be facilitated by running them at night.

You shouldn’t have to worry about burned or heat-stressed plants if you apply some basic automation and follow some common-sense procedures. The key is to constantly monitor your plants so that you can see any problems early and take action to rectify them.
