The Gavita Pro 1000 (906050) is the latest edition of high pressure sodium lamps to come from Gavita. With all the hype surrounding double-ended (DE) bulbs, we simply couldn’t ignore the opportunity to try one out, and…

we were quite pleased with the results.


Double-Ended Technology

We’re always a bit skeptical about new grow light technology, especially when it’s cheap. We’ve seen our own fair share of duds when LEDs and plasma lights first came out, so our expectations weren’t too high towards this new double-ended hype. But the Gavita far exceeded even our highest expectations. We ran it side-by-side next to a 1000-watt HPS, and it performed beautifully; yield and quality were almost identical, if not better under the Pro 1000. Gavita attributes its higher performance to the fact that the ballast comes attached to the reflector, preventing any RF interference. Since it’s coming from Gavita, we think it’s safe to take their word for it.

“far exceeded even our highest expectations”


In the cannabis business, you’ll be spending anywhere from $500 to $1000 for a decent single-lamp setup (even more if you decide to get a plasma light), and you might be lucky to keep everything running at full potential for a good year or so until the bulb begins to degrade. The Pro 1000, on the other hand, doesn’t only give you the entire combo for less than $500, but promises to run at 90% of its max output for up to three years with minimal degradation. Even if you can get a plasma light on sale, you may want to opt for the this Gavita HPS instead.



Even at the highest possible wattage, we didn’t experience a huge rise in temperature. Gavita has done a great job in designing the Pro Thousand to dissipate heat, and it certainly helps that the ballast sits next to the bulb itself. We still had to stick to cooling our room down while using it, but the Gavita 1000 certainly requires much less heat dissipation than other standard reflectors on the market.


Coverage Area

“coverage area isn’t a square like most other reflectors, but a rectangle”

One of the biggest differences in this lamp from other hood set ups is the coverage area. When we first hung the reflector up, we noticed that the coverage area isn’t a square like most other reflectors, but a rectangle. This is a big deal when it comes to growing cannabis, especially indoors. A big part of the setup is usually dedicated to figuring out how lights need to be positioned for efficient light coverage. Theoretically, with the improved spectrum and high PAR output, you could possibly swap two air-cooled HPS reflectors covering a 4’ x 8’ with a single Pro 1000 and achieve similar results. Of course, we know this can be awkward for many growers who are used to square lights, but we believe it’s definitely worth it.


Bottom Line

Whether you’re just starting out or you’re a seasoned veteran in cannabis growing, we highly recommend the Gavita Pro 1000. Gavita products may seem pricey at first, but if you happen to find Gavita lights for sale that utilize this new grow light technology, we recommend you jump on it fast. Even at full price, it’s relatively inexpensive compared to other grow lights, especially when you consider that one of these can replace two HPS reflectors, and it delivers as promised.
