Factors To Look For When Buying Best LED Grow Light
For indoor gardening, or if you have a small greenhouse, you would want to invest only in the best quality LED grow lights. When you are on the hunt for the best LED grow lights, you need to consider the following factors:
1. Power Usage
You are required to have the grow lights on for at least 18 hours during the germination phase and then for 12 hours throughout the growth to the final fruit-bearing stage. Hence, you must consider the power consumption of the LED lights.
The LED grow lights offer much lower electricity consumption as compared to metal halide or ceramic metal halide. That said, there are grow light manufacturers that offer even better power usage and lesser wattage.
2. Your Requirements
Whether you aim to have a small indoor herb garden, or you aim for a greenhouse, you need to choose your place and usage before you decide on the type of grow light.
The indoor gardening requires you to opt for less noisy and better heat dissipation option. While the outdoor ones require you to focus on factors like water resistance and fireproof.
Most heat sinks come with aluminum for effective cooling without the need for fans. Greenhouses can also look for the daisy chain system so that you can have multiple units linked to each other with a single power source.
3. Appearance And Size
Why opt for something chunky when you can get the best with a sleek design? Often the appearance of the grow lights matter. The appearance also is impacted by the size of the grow light.
If you are looking to bloom the occasional flower, then you can opt for a smaller grow light while greenhouse owners should invest in ones that are larger with higher light intensity.
It is very important that you must consider the durability factor before buying LED grow lights. Since this will incur some cost, hence, it becomes important that you must choose the lights which last longer.
The durability depends on the diodes and the board technology used. These two factors affect the working of the LED lamps. Zener diodes make sure that even if one lamp goes off, the others will continue to work.
The heat dissipation also affects lamp durability. If the heat sink and fans work properly, then the lamp will stay cool to work for a longer time.
5. PAR Value
PAR or Photosynthetically Active Radiation is the ideal spectrum for plant growths. Being the alternative of sunlight, the grow light helps the plants to grow via photosynthesis. Unless the grow light has a high PAR value, it will not ensure proper nutrients to reach the plants.
Lack of proper energy will make the plants grow stunted and unhealthy. To ensure uniform PAR distribution, the surface area of the garden should be lesser than the core coverage area of the grow light.
If you plan to have decent produce in terms of herbs and salad garden, then you need to invest more in the grow lights. The simple math is that for better coverage and higher yield, you need more light, which will give you more PAR, which will also cover the higher surface area. Thus you will have quality and quantity in terms of yield if you opt for the higher range of grow lights.
FAQs on LED Grow Lights
1. Are LED Grow Lights Beneficial?
LEDs are considered to be the best in terms of light intensity without consuming much electricity. Given that you need to have the lights on for longer, the power consumption becomes a primary concern. The best LED Grow lights offer the users with lesser electricity bill, a wider spectrum of light, safe for children as no mercury is present, and good for indoor use with effective cooling systems.
2. What Should Be The Right Watt/Surface Area For Indoor Gardening?
When you go out there to but LED grow lights, you will find different watt lights. It must be more than 32 watts per square foot. But, if you are looking for optimal growth, then you must look for 50 watt- 80 watts. You can consider the following table.
- 1ft. by 1ft. – 32W
- 2 ft. by 2 ft. – 128W
- 3 ft. by 3 ft. – 288W
- 4 ft. by 4 ft. – 512W
- 6 ft. by 6 ft. – 1152W
3. What Is PPFD?
PPFD or photosynthetic photon flux density is a measurement of photons present in the range of 400-700nm of visible light. The higher value of this PPFD, the more energy the plant gets to perform its daily functions. Think of PPFD like glucose for humans. When you have more energy, you perform better.
4. What Is The Best Grow Light Placement Height For A Good Canopy?
Keeping in mind the PAR value and the angles of the lenses, the ideal height at which the grow light should be placed between 18 inches to 36 inches. Still, different brands come with different recommendations. Check out the user manual for the best canopy.
Choose The Right LED Grow Lights And Let The Plants Bloom
