Should you go for LED grow lights for growing plants indoor?

The answer to this important question is a big YES! One may argue that LED’s are expensive and we do agree. It might be a sizable investment if you’re a beginner to indoor growing and hydroponics. However in the long run, you will enjoy the dividends as LED grow lights consume way less energy than alternative light sources with Viparspectra Grow Lights under review consuming only 136 watts.

Alternative HPS/MH HID (High Pressure Sodium/Metal Halide High Intensity Discharge) lighting requires the services of ballasts, a component that keeps their light from flickering extensively and ballasts emit a lot of heat and consume a lot of power. In comparison, LED’s create less heat, therefor you will be saving the energy that you spend on cooling mechanisms too.

HPS/MH HID can be costly in maintenance too with them requiring frequent bulb replacements. When you consider all these savings, it’s a wise choice to go for LED grow lights. The fact that Viparspectra now offers a range of reliable LED lighting products at affordable rates brings you another step closer to that crucial choice.

Thinking about replacing your HPS/ HID grow lights?

Viparspectra 300W LED Grow Light is the ideal replacement for 250W HPS/HID light. The LED light doesn’t require a ballast. It takes care of cooling too with in-built large cooling fans and heat sinks while consuming only 136 Watts although it’s been rated for a 300 watt output.

If you’re currently using incandescent bulbs, wherever you found them, the Viparspectra 300 Grow Light can replace three of those.

Light Intensity & Coverage

It’s very important to keep in mind that there’s no point of measuring light intensity with Lumens. It’s highly irrelevant if a light looks bright to human lights or not, because we’re looking to provide sufficient light for plants which respond to different light wavelengths when compared to us humans.

Photosynthetically Active Radiation (PAR) designates the wave band of solar radiation between 400 and 700 nanometers that plants use for the process of photosynthesis, making it the ideal measurement of light intensity and coverage for grow lights.

Viparspectra 300 PAR Value

Viparspectra 300W LED Grow Light provides is a full spectrum LED grow light, making it ideal for many types of plants in various phases in their growth cycle. Coverage is very important as some grow lights focus the light output more towards the center creating hots spots and uneven coverage. This is mainly due to design flaws. In comparison, Viparspectra 300 Grow Light shines bright with a good design to provide even light coverage.

Viparspectra 300 PAR Value Heights

When placed above 24 inches from the canopy of your plants, the PAR maps out to provide the best coverage within an area of 2 feet by 2 feet. The light does reach out to an area of 3 by 3 feet, but it’s not a good idea to cramp in too many plants since flowering needs a lot of light, so for optimum growth, using a Viparspectra 300 LED Grow Light per 2 square feet is optimal for growing.

When it comes to the number of plants per LED light, we highly recommend two per light with around 2.25 square feet for a mature plant without supplemental lighting for flowering. You can squeeze in four per light if you’re willing to add more lighting for flowering when it’s needed.
