Why is the Viparspectra 300w so popular?

For starters, Viparspectra is still a fairly new company, but has already started off with a great reputation for creating LED’s that make the mark for indoor growers. Every LED grow light they make, from the Viparspectra 450w to the PAR600 is built with indoor growing in mind.


Also, the typical 5 watt LED bulbs nestled into each and every Viparspectra has been quality tested and set up to take full advantage of its full spectrum array of light. LED’s in fact have so many benefits for indoor growers that at this point in time, settling for a different type of bulb is almost foolish.

Benefits of LED Bulbs

Bulbs are probably the single most important thing to consider when growing. With LED bulb the advantage is obvious.

  • Energy usage is drastically cut in half compared to HPS bulbs or similar
  • Heat reduction. Plants hate to much heat when growing
  • Life expectancy is around 50,000 hours
  • Far less costly. Especially with the Viparspectra 300w LED grow light
  • Full spectrum LED light allows the use of both veg and bloom lighting cycles

So, you can see why LED’s have pretty much taken over the grow light market. The Viparspectra 300w LED is no exception.

To start, the panel of this Viparspectra is easy to use and operate. Perfect for beginners who typically start with a small grow of maybe 1 or 2 plants. It has a fairly small coverage area at around 2 feet by 2 feet. It does however reach deep through the plants canopy and does it well.

Daisy Chain LED Grow Lights

Although the Viparspectra 300 watt V300 is small, but it can be expanded as your grow room expands. The feature is called a “daisy chain”. This allows you to connect a series of LED’s together to increase your growing yields by producing more plants. They simply plug in, one after the other to multiply your light output and increase your coverage area. A very nice feature.

This means that if you start to get the knack of indoor growing, you can easily expand and grow more.

Viparspectra 300 watt light output specifications

PAR and lumen are the measurements of light output for a particular LED grow light and lighting in general. Many people get caught up in this measure but keep in mind their are many factors that ultimatley control the yeild of your crop and adverse effects on your plants.

The more PAR and Lumens, the stronger intesity of your LED. V300’s PAR is best when the light is hung 2 feet over the top of the plants canopy. With this in mind, the ease at which the light is able to be raised is efficient with the included hanging kit. I ted to ignore lumens as this is a measure of light intesity to the human eye which is dangerous of you are trying to measure this yourself. Never stare directly at LED’s even if they seem dim. Always use protective wear such as the Apollo Indoor Growing Glasses.

PAR is more of the lighting measure we are after. It combines light coverage along with intensity. Based on the Viparspectra 300 watt grow light PAR plants in their vegetative cycle should have the lighting coverage at 2 feet by 2 feet and the same goes for the flowering stage for best growth results. Keep in mind, don’t crowd your plants. If you need more plants, you will need more lights. If this is the case, these lights have a daisy chain feature that can accommodate this.

How many plants can you grow with the Viparspectra 300W?

One cannabis plant generally means one square foot, which means with the Viparspectra 300w reflector series LED grow light you can conceivably grow 2 plants at a time. Total best coverage area is 2×2 although you can expand out to a 3×3 growing area, which we do not recommend. If you need that 3rd plant you should buy 2 of these LED lights.
