7 Mistakes to Avoid When Using LED Grow Lights


Many people all around the world have indoor plants at their homes, be it for recreational or medicinal purposes, and while some of them do get the great harvest but some don’t work so well – their plants wither quickly or produce insignificant yields. Grow lights are the efficient tools for making a great harvest, but if they are used improperly, the plants would also be damaged.

This article would talk about seven mistakes you should avoid with using grow lights for growing.

Overheating the Plants

Overheating is one of the most important issues that need to be considered when using grow light with large power. When the plants are so close to the lights the leaves, plants would be damaged and would have some signs. One is that the leaves would turn brown. The curling leaves are another sign of the plant being damaged by over-heating. So when using grow light, you should pay attention to the growing status of the plants and make the daily monitorization so that these signs could be caught quickly you will have a chance to change the hanging light of the grow lights to avoid further damage. Also, good ventilation is very important for avoiding the overheating issue, and adding fans would be also helpful.

Providing Insufficient Lighting

If the coverage of the grow light is matched with your growing scale, and offer the proper light illumination for your growing. So when buying the proper grow light, you should also pay attention to the PPFD map and the footprint of the grow lights. Make sure that you have enough lamps but still look for a good balance between providing sufficient lighting and not overdoing it.

Setting the Lamps at an Improper Distance

Overheating is caused by improper distance (How to Set Proper LED Grow Light Distance). If the lights are put too far from the plants, then plants get insufficient light. There is no universal rule for setting the distance but it’s recommended that LEDs are placed 12 to 18 inches away from the plants. You could get the reference from the grow light sellers.

Using Inferior Products

Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process. If you’re using regular incandescent lights, you’re not very likely to grow strong and healthy plants. Therefore, for best results, it is recommended that you use full spectrum LED grow lights. They are specifically designed for the purpose and have the feature to deliver light in the exact spectrum the plant needs.

Selecting the Wrong Light Spectrum

Plants need different light and spectrum at different growth stages. To grow efficiently, full-spectrum LED lights(How Different Lights Affect Plant Growth) would be much more efficient fo for the healthy growth of the plants, and light with dimming features would be operated easily. For example, in the vegetative stage of growth, plants need blue spectrum. If you set the red spectrum dimming, the plant growth would be hindered.

Using the Wrong Light Schedule

You should be careful not to leave the lights on all the time, or worse, the opposite – forget to turn them on. It might sound trivial but it’s quite easy to mess up the light schedule and even a minor change might have a negative impact on the plant’s growth. Usually, medical plants need about 18-24 hours of light during the vegetative stage and 12 hours of light during the flowering stage.

Not Protecting and Maintaining the LED Lights

Investing LED grow lights is not cheap, so a good maintenance is also very important, which could extend the life of grow lights. Good maintenance and proper operation save you a lot of trouble and money. It is recommended that You could set up a power stabilizer and connect it to the lights to equalize the incoming voltage, thus protecting the chip inside the LEDs.
