How can growers choose the best LED Grow Lights?

LED grow lights have gained immense popularity in recent years. While the initial investment may be higher than traditional HPS lights, the long-term benefits of LED grow lights are undeniable. They are more efficient, offering a wider spectrum, consuming less energy, providing better uniformity and coverage, lasting longer, and emitting less heat. Most importantly, they deliver higher production and superior quality yields.

Desired Coverage Area

This is a crucial factor to consider when selecting LED grow lights. Each grow light is suitable for a specific grow space. By determining the system dimensions and fixture output, you can choose the ideal hanging height for your plants at different stages of growth.

Wattage per Square Meter (W/m2)

The recommended wattage per square meter is typically 300 to 400 Watts for cannabis and other light-hungry plants. However, the wattage requirement may vary depending on the plant species you intend to grow. Dimming the lights can help you achieve the desired intensity without adjusting the canopy height.

Light Spread Uniformity

When purchasing grow lights, it is essential to ensure that photons are evenly distributed across the entire canopy. Some companies focus solely on the center of the grow canopy, leading to uneven growth. Thus, it is important to choose a grow light that provides uniform coverage to avoid uneven canopies.

Efficacy (µmol/J)

Efficacy refers to how efficiently a grow light can convert input wattage into usable PAR. It is an important factor to consider when choosing LED grow lights. You can calculate efficacy by dividing the total PPF output by the total input power. Avoid lights with high wattage but low efficacy.

Spectrum

The spectrum of LED grow lights is crucial for the different stages of plant growth. A full spectrum fixture is recommended if you want to grow plants from seedling to harvest indoors. The spectrum should include blue light for vegetative growth, red light for flowering, and green light to promote chlorophyll production and penetrate thick canopies.

Energy Consumption

In the past, growers focused solely on watts as a measure of energy consumption. However, it is important to consider the overall energy consumption of your grow lights. Higher wattage may result in increased electricity costs, so it is essential to calculate the potential expenses and ensure they align with your profit goals.

Diodes

Pay close attention to the diodes used in LED grow lights. Top-tier manufacturers like Lumileds and Osram produce highly efficient and long-lasting diodes that operate at lower temperatures. Lower LED temperatures improve performance, durability, and reliability.

CRI (Colored Rendering Index)

The CRI of LED grow lights determines how accurately they represent the natural colors of plants. Lights with a higher CRI provide a more natural color representation. Avoid lights that emit a purple hue, as they may hinder your ability to detect problems in your plants.

Quality of the Material

Consider the overall build quality of the grow light fixture. Look for a robust and solid chassis, as well as aluminum heat sinks that efficiently dissipate heat.

€/Wattage or €/µmol

When comparing prices, focus on the cost per micro mole (µmol) rather than per wattage. Growing plants respond to micro moles rather than watts. Opt for a fixture with higher efficacy to ensure cost-effective PPF output.

Replaceable Parts, Modularity, and Company Assistance

Choosing a brand that offers replaceable parts, modularity, and excellent customer support can be beneficial when buying LED grow lights. The ability to change components and seek assistance increases trust and makes it easier to resell used equipment.

Warranty

A comprehensive and long warranty is crucial when investing in LED grow lights. Look for a company that stands behind their product and offers reliable support in case of any issues.
