Factors that Affect the Requirement of Grow Light

How many LED grow lights you need for a specific area highly depends on not one but several factors. To ensure that your plants get proper lighting, you need to consider these factors. Wrong planning can hurt your plants.

The factors that affect the requirements of grow lights are:

Coverage Area

 

Coverage Area

 

The first factor you need to consider is how much area the light will be covering. Usually, lights with low power cover less space than the ones with higher watts. A 300 watt LED light can cover an area of 6 to 10 square feet. So, check how many plants you’re growing within this area.

Distance from the Plants

Based on how far you place the light from the plants, the number will vary. On average, people put LED lights from 14 to 30 inches away from the plants. The main consideration here is the type of plant you’re growing. Some require the lights to be close, while others grow better from a long distance. However, the distance will affect the coverage area, which affects the number of plants you can grow under one light.

The density of the Plants

The density of the plants is another factor to consider. As we have told you earlier, a 300 watt LED light covers an 8 to 10 square feet area. So, if you have one plant in every 4 square feet, then you can grow 2 to 3 plants with one light. And if you have one in every 2 square feet, you can grow 4 to 5 plants easily.

Plants You’re Growing

Different plants require different heat and different densities. So, based on their requirements, you determine the distance of the light from the plants. Not only that, but also you have to maintain the required density. So, you can say the type of plant is a great factor here. It is highly influential in determining the number of plants to grow under one 300w LED light.

How to Determine the Number of Plants a LED Light Can Cover

So, now the question is how to determine how many plants the LED bulb will cover. The process is quite simple. Just consider the factor explained above, and you will find the number.

However, for your convenience, we’re explaining the process in brief:

  • First, determine what plants you’ll grow.
  • Then decide what will be the density of the plants. Find out how much area one plant will cover. For example, we’re assuming one plant will take 2 square feet of an area.
  • Now determine the distance and coverage area. Suppose your plant requires the lights to be 18 inches away. In this case, a 300w LED bulb will roughly cover 8 square feet.
  • Now divide the coverage area with the area one plant will take. Here in the example, dividing 8 by 2, we get 4. That means you can grow 4 plants with a 300w LED light. So, if you’re growing 40 plants, you’ll need 10 light bulbs.
