Viparspectra released their new quantum style LED grow lights called the Pro Series. This series of grow lights consists of five models that range in coverage area from 2×2 feet to 2×6 feet. are a nice upgrade from previous Viparspectra grow light models.

The previous Viparspectra grow lights were a bit weak for growing cannabis unless you bought the more expensive models. The Viparspectra Pro Series feature stronger light than the previous models, which makes these a much more attractive option for cannabis growers looking for a familiar brand to grow with.

I bought the P1000 and tested it myself, you can check out my video towards the bottom of the page, but more importantly read below for all the details about my experience with the P1000.

Which Phases of Cannabis Growth are the Viparspectra Pro Series Grow Lights Good For?

Based on the specifications provided by Viparspectra as well as my own testing, you can use the Viparspectra P1000 or the Viparspectra P1500 to grow your cannabis from seedling to flowering phase.

Will The Pro Series Grow Lights Grow Cannabis Well?

Cannabis requires a minimum 300 micromoles of light during the vegetative phase and 460 micromoles of light during flowering. Technically yields will increase up to 1500 micromoles during flowering (see study cited below).

The Viparspectra Pro Series grow lights meet those light intensity requirements. All models will grow well during the vegetative phase, and decent yields during flowering.

The intensity on the P1000 and P1500 could definitely be stronger, but considering the cost of the Viparspectra Pro Series grow lights, I’d say they fall in line performance-wise. The P2000 and P2500 are strong enough to flower your cannabis plants well.

If you want a grow light with stronger intensity for flowering, consider my up to date list of the best LED grow lights for cannabis. It’ll likely cost you more than Viparspectra though.

You can read more about cannabis light requirements by reading my long article on the topic here. Let’s take a look at the rest of the design and specifications.

The Viparspectra Pro Series includes four models – the P1000, P1500, P2500, and P4000. They all look the same (see images above), but the higher number variants are each slightly longer. The number in the light name correlates to it’s true wattage. For example, the P1000 is a 100 watt grow light. The P4000 is a 400 watt growlight.

The P1000 measures in at 13.7 inches long and 11 inches wide. The P1500 is about 19 inches long and 11 inches wide. The P2000 is 25 inches long and 11 inches wide. The P2500 is 32 inches long and 11 inches wide.

All models include an aluminum heat sink on the rear side. These grow lights pull between 100 and 250 watts of electricity depending which size you choose. For that level of power I wouldn’t worry about heat generation, but the aluminum heat sink is there just in case.

One nice feature on the Viparspectra Pro Series grow lights is the dimming knob on the side of the light. It sounds really simple, but some of the most popular quantum board grow light brands make you stick a screwdriver into a tiny hole on the driver. That’s really inconvenient, and I appreciate Viparspectra adding this feature to the Pro Series models.

These grow lights use no-name SMD LEDs, if you’re looking for brand name parts you may want to consider the slightly more expensive Spider Farmer.

Light Spectrum:

The light spectrum on the Viparspectra Pro Series models is the same. It’s a white color spectrum consisting of 640-660nm (far red), 3000-3500K(red), and 6500-7500K(blue). This spectrum will grow your plants in all phases of growth.

I’ve not seen 6500K-7500K used on a grow light before, so that’s pretty interesting. Other grow lights use either 4000K or 5000K for their blue wavelengths.

It’s probably not much different than 4000K or 5000K. It’s just a different way of doing it. The one thing that disappoints me is the lack of infrared LEDs.

I haven’t seen any of the modern quantum style grow lights include ultraviolet like many of the purple spectrum and COB LED grow lights have. But a lot of them still include infrared which is beneficial to cannabis. So it’s disappointing to not see infrared included on the Viparspectra Pro Series. After all, it’s the “Pro Series.”

Coverage Area:

As mentioned above, the P1000 covers a 2×2 foot area, the P1500 covers 2×3 feet, the P2000 covers 2×4 feet and the P2500 covers 2×5 feet.

If you choose the P1000 or P1500, these grow lights are not as strong as the others, so you can hang them much closer to your plants than you would with most other grow lights.

Looking at the Viparspectra P1000 intensity map above, you can see at 12 inches above your plants the peak intensity is 650-800 micromoles, which is perfect for flowering. Most other grow lights would hang at 18 inches, so the P1000 allows an extra 6 inches of space for your plants to grow.

During the seedling phase you’ll need to hang the P1000 and P1500 at 20-22 inches, or use the dimmer. Ideally you’d want about 200-250 micromoles of intensity for seedlings.

The larger P2000 and P2500 models emit stronger light due to the larger number of LEDs, and should be hanged at 26 inches for seedlings, 22 inches for veg, and 18 inches for flowering.

How Do Viparspectra Pro Series Compare To Similar Grow Lights?

There are so many grow lights on the market that it’s hard to make a decision. Most people I talk to just pick the model their friend has, pick an inexpensive model, and some take my advice on the best bang for your buck grow light models.

I think the lower end models (P1000 and P1500) have tough competition in the Mars Hydro TS-1000 (compares to Viparspectra P1000), and the Spider Farmer SF-2000 (compares to Viparspectra P1500). These two models compare the closest in terms of price and performance.

The Mars Hydro TS-1000 emits stronger light and includes infrared in the spectrum. At a very similar price to the Viparspectra P1000, I’d probably take the Mars Hydro TS-1000. The TS-1000 will be a bit more frustrating to dim, but I would say that’s the only downside.

The Spider Farmer SF-2000 is considerably more expensive than the Viparspectra P1500. But it also emits stronger light and includes infrared wavelengths in the spectrum. The Spider Farmer will be a bit tough to dim. So this is a more difficult choice, but I think if you can afford the Spider Farmer SF-2000 you should choose that one.

The larger models, P2000 and P2500, offer more performance and I think these are solid competitors to other popular brands like Bestva and Phlizon.

Viparspectra also makes another similar series of grow lights called the VP Series. This series is a bit different from the Pro Series, mainly in that they aren’t dimmable and the smallest version probably isn’t ideal for flowering.

With that said, the VP series features daisy chain function, which is first of it’s kind on a quantum style grow light. The VP and Pro Series are priced similarly. I personally prefer the Pro Series, but it may be worth checking out the VP series for the sake of it.

Viparspectra Yield:

In addition to my own solid results, I can’t tell you how many other growers I’ve heard rant and rave about the buds Viparspectra produces. Much more than simply saying that these are good lights. People who grow with Viparspectra grow lights quickly become loyal fans.

While lights aren’t the only factor that affect cannabis yield, Viparpsectra is definitely a great piece of the high yield puzzle when used correctly along with maintaining other environmental factors. I love the way these grow lights perform!

My Final Opinion About Viparspectra Pro Series Grow Lights:

Overall, the newly designed Viparspectra Pro Series offer a solid bang for your buck. My one only disappointment is that they didn’t include the infrared LEDs. But a lot of growers including me LOVE the Viparspectra spectrum, and the plants it produces.

If you choose one of these grow lights you’ll definitely be able to grow your cannabis without issue. They are strong enough, and the dimmer knob is such a nice feature!
