Viparspectra VP Series Grow Lights – VP1000 & VP2000 Comparison
Viparspectra released their new quantum style LED grow lights. The VP Series VP1000 and VP2000 models 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.
Let’s take a look at the specs on the new Viparspectra VP1000 and VP2000 grow lights:

Which Phases of Cannabis Growth are the Viparspectra VP Series Grow Lights Good For?
Based on the specifications provided by Viparspectra as well as my own testing, you can use the Viparspectra VP1000 or the Viparspectra P2000 to grow your cannabis from seedling to flowering phase.
Will these 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).
In my opinion the VP1000 is not strong enough to flower cannabis. Sure you can probably pull it off but it might be similar to driving a car with flat tires. Based on the intensity of light emitted by each of these VP Series models, I’d only use the VP2000 for flowering. You can use the VP1000 for seedlings and veg.
The intensity on the VP1000 and VP2000 could definitely be stronger, but considering the cost of the Viparspectra VP Series grow lights, I’d say they fall in line performance-wise. I always say you get what you pay for, so make sure you know what you’re paying for! Stick to the VP2000 if you need a full cycle grow light.
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 the VP series will 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.
VP1000 (2×2 feet coverage):
VP2000 (2×3 feet coverage)
The Viparspectra Pro Series includes two models – the VP1000 and VP2000. They look the same, but the VP2000 variant is slightly longer than the VP1000.
The VP1000 measures in at 11.2 inches long and 13.8 inches wide. The VP2000 is about 24 inches long and 14 inches wide.
All models include an aluminum heat sink on the rear side. These grow lights pull between 100 and 200 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 VP Series grow lights is the daisy chain power inlet on the top side of the grow light. It sounds really simple, but most new grow light models have ditched the daisy chain feature. It adds a bit of convenience on these grow lights, and I appreciate Viparspectra adding this feature to the VP Series.
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.
The light spectrum on the Viparspectra VP 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 VP Series.
Because the VP1000 and VP2000 grow lights are not as strong as many other grow lights, so you can hang them closer to your plants than you would hang most other grow lights.
During the seedling phase you’ll need to hang the VP1000 at 20 inches above the seedlings. Ideally you’d want about 200-250 micromoles of intensity for seedlings. The VP2000 would hang about 24-26 inches above your seedlings.
Looking at the Viparspectra VP1000 intensity map above, you can see at 16 inches above your plants the peak intensity is 460 micromoles, which is perfect for the vegetative phase. Most other grow lights would hang at 18 inches, so the VP1000 allows an extra couple inches of space for your plants to grow.
I don’t recommend flowering with the VP1000, but if you decide to try it you’d need to hang the light 6-12 inches above your plants to get a high enough intensity that plants crave during flowering – between 460 and 925 micromoles of light.
If you choose the VP2000 you can hang it 16-18 inches during the vegetative phase, and 10-12 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 VP1000 and VP2000 have tough competition in the Mars Hydro TS-1000 (compares to Viparspectra VP1000), and the Spider Farmer SF-2000 (compares to Viparspectra VP2000). 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 similar price to the Viparspectra VP1000, 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 VP2000. 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.
You can also compare these grow lights to the Viparspectra Pro Series grow lights which are a bit better and almost the same price.
My Final Opinion About Viparspectra VP Series Grow Lights:
Overall, the newly designed Viparspectra VP Series are not bad. But they leave a bit to be desired. My main disappointment is that they didn’t include the important infrared LEDs. The light on the VP1000 could also be a bit more intense.
With that said, if you choose one of these grow lights you’ll definitely be able to grow your cannabis without issue.

Yes these grow lights will grow your cannabis from seedling to flowering phase.
For seedlings you should hang the lights 22 inches above the canopy. For vegetative and flowering phase you should hang the lights 12 inches above the canopy.
The VP1000 will light 2×2 feet, the VP2000 will light 2×3 feet.
The Pro Series grow lights are dimmable, but the VP series are not. The VP Series are daisy chainable, but the Pro Series are not. The price of both variants are similar.
