How to Choose a Good LED Grow Light? Where should LED Grow Lights be Placed?

The benefits are quite obvious for those people who like cannabis very much. Growing the cannabis at home which makes the cost is drastically lower compare buying it outside. Many people all around the world grow cannabis in their homes, being for recreational or medicinal purposes, and while some do quite well and manage the cannabis into good product, but for other cannabis growers work not well– their cannabis withers quickly or produce insignificant yields. And these issues might be related to improper usage of the lighting systems. (The same issues affect other types of plants as well)

Recently, more and more people start to use LED Grow Light instead of the HPS Grow Light, as it has better efficiency and longer life with lower electricity bills. Led Grow Light has rapidly developed in the last few years as growing cannabis is becoming legal, especially in the USA. Grow lights are a great tool for making the growing process more efficient, but they can also be harmful to the plant by using them in the wrong way. I'm going to share some tips to let you know how to use led grow light correctly.

Here are 10 tips you should know when using LED grow light to healthy-looking plants and avoid any unnecessary hassle:

Overheating

You will know if the plant takes too much heat by the leaves starts turning brownish. The first signs look like thin outlines on the outside of the leaves, so if you could catch this quickly you will have a chance to avoid further damage. If some of the leaves start curling up, it might also be a warning that the plant is too close to the LED grow light. Good ventilation usually helps with this issue also, so put putting fans in the grow room or grow tent will be a good idea to take this over.

Insufficient Lighting

It is important to consider how high you put the LED grow light, and how many plants you grow with one LED grow light. Think about how many plants you`re growing and how many Led Grow Lights you`ll need in order to illuminate them properly. You should also be aware of the luminosity of the lights you`re using. For example, a 600W LED light is sufficient for a yield of about 400 grams. Make sure that you have enough LEDs, but still, look for a good balance between providing sufficient lighting and not overdoing it. Here is the information for different plants below.

Setting the Light at an Improper Hight

Overheating or insufficient lighting can result from having too many or not enough lights, but it can also result from placing the lights too close or too far from the plants. My recommendation is to place the LED grow light 12 to 18 inches away from the plants, but depending on the growing stage.

Using Inferior LED Grow Light

Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process. With the increasing demand for LED grow light market, many companies have shifted from commercial lighting to grow light market. They sell inferior LED grow light to others under the banner of cheap, so when buying the light, you got to be very careful as a lot of companies cheat people. Spectrum, diodes, driver, and the brand that's all you need to think about.

GOOD LED GROW LIGHT

Wrong Light Spectrum

In order to grow efficiently, plants need different types of light in each growth stage. By using a full-spectrum LED light it would be a easy case, but if you select the wrong LED grow light, the plant will not grow well as the normal one. You should also take into consideration the conditions in the room where you're doing the growing. (Tip: higher blue is for seeding and leaves, higher red is for blooming and fruiting)

Wrong Using Schedule

Do not turn the light on for 24h. Some growers think longer lighting time will make the plant better, but the plant needs rest also. Cannabis needs about 18-24h of light during the vegetative stage and 12h of light during the flowering stage for better growing.

Forget to Adjust the Lights

Many new growers forget to dim the spectrum, or adjust the height between the lights and the plants. If you doing like that the light with burnt leaves. Another important thing is to occasionally rotate the pots in order to prevent the plants from leaning towards the light too much.

LED Grow Lights are a great tool when growing plants indoors. In order to produce good and healthy yields, please think about other factors- room temperature, soil, nutrients, plant genetics, airflow circulation, and many other things. Don`t just focus on a single part of the growing process. Instead, trying to understand the whole chain and how everything is interconnected, you will be an expert in indoor planting.
