HPS or LED Grow Lights for Indoor Gardening

When starting an indoor garden or trying to grow plants inside, you need the right tools to such grow lights to keep your plants happy and healthy. A grow light is essential to indoor plants where there is not enough sun indoors to keep plants thriving.

But with so many types of grow lights on the market, it can be difficult to find the best product for your indoor setup. There are a few features to keep in mind when looking for a grow light:

  • Sun spectrum
  • PAR intensity
  • Efficiency
  • Number of watts

Sun Spectrum

Sun spectrum refers to the wavelengths of light produced by a light source—like the sun—that promotes plant growth. Controlling the light spectrum of a grow lamp significantly impacts the growth of plants including how plants flower and the flavor and compactness of crops.

PAR Intensity

Photosynthetic active radiation, or PAR, or the spectrum of light wavelengths needed for photosynthesis. Plants need a range of around 400-700 nanometers of light to thrive, but some plants require wavelengths outside of this range. A grow light should accommodate to the PAR intensity your particular plants need.

Efficiency

Photosynthetic efficiency is the best range where plants will grow. While you might think a grow light just needs to mimic sunlight, not all plants will thrive in sunlight alone. Studies show that a range of light including red and blue light is critical to photosynthesis.

Number of watts

It can be difficult to decide how much wattage you need for your indoor plants, but as a general rule you want a grow light that will accommodate 20 to 40 watts of light per square foot. With a 1000-watt light, you can properly light between 25 and 50 square feet of your indoor garden.

Now that we have explained the features of most grow lights, now to choose what type of grow light is the best option for your indoor plants.

Best HPS Lights For Indoor Growing

High-pressure sodium vapor, or HPS, lights are a specific type of light that contains metals that are evaporated into the gas within the glass bulb, creating light. This type of HPS light has been used since the early 1930s as a reliable light source that can efficiently light large spaces.

For hobbyists, one of the best HPS grow lights is the Sun System HPS 150W Fixture with Ultra Sun Lamp. Best for growing in small areas, it is an efficient, inexpensive option for those who are just starting out.

Commercial growers tend to gravitate toward lights like the Gavita Pro 1000w E-Series Slim Line DE Fixture HPS grow light, which comes in a variety of voltages and covers a wider footprint.
