HYDRA-1000 100W LED Grow Light Full Spectrum - Samsung LM301B LED Diodes, Daisy Chain Dimmable Grow Lamp for Indoor Plants Veg Flower Hydroponic Greenhouse 2x2ft Coverage

My overall assessment of the HYDRA-1000 is that it is an excellent, well thought out and full-featured light, and very appropriately priced given its capabilities. I’m not one to ever place form anywhere near function, but the HYDRA-1000 is an attractive light, both in terms of the board and the digital dimmer display. Its weight is very low, as well, and being a US-based company actually does matter to me (even if electronics manufacturing necessarily requires foreign production). Having an ON/OFF switch is a nice thing, too. If you don’t have the luxury of a dedicated grow room or climate controlled space for a large enclosure, these lights will allow you to piecemeal your enclosure and lighting solutions according to your available space.The inclusion of two quality ratchet hangers and three stout wire hangers is a nice touch, relieving the user of the need to address hanging options through additional purchases. Providing this equipment should be a standard practice, but Atreum sets itself apart in this way The light may be hung directly from the ratchet hangers, though the wire hangers allow the lights to be hung a bit lower if your plants are short and your grow space is tall.As for light output and efficiency, Atreum appears to advertise accurately, which is something I find lacking in the industry. I wanted to get the lights into service, so I did only an impromptu PPFD map inside a 22”x22” Mylar enclosure. The numbers from my Apogee MQ-500 essentially match those of Atreum and MANY reviews on YouTube which provide detailed PAR maps and efficiency measurements. Atreum isn’t at all shy about this product, nor should they be. The inclusion of infrared LEDs matches the state of the industry, and this light will easily provide for your desired DLI when used in an appropriately sized grow space. The digital display may read 99-100W when cold, but expect the number to be in the 97-98 range once the diodes reach operating temperature.The apparent big names in LED grow lighting seem to be advertising reputable and efficient component brands, and Atreum doesn’t fail to keep pace by using Mean Well drivers and Samsung LM301B diodes. The HYDRA-1000 is set apart by the spacing of the diodes. This does away with some of the useless center hot spot and weak corner/edge issues, and I find that to be particularly useful when striking the balance between hanging height and average PPFD in a 2’x4’ tent with two 100W-range quantum boards. Having the very accurate and fully adjustable dimming feature reduces the amount of height adjustment required for this purpose, especially when multiple lights are linked.The extension cable for the driver and dimmer allows those items to be kept outside of the enclosure, and it’s long enough to be useful. In addition to helping with heat management, it allows the wonderful dimmer display and control to be placed in reach and in view. I’m rather enthusiastic about this feature. With two 4” fans for air circulation at plant level, and the duct fan replacing the volume of air in the 2’x4’ tent roughly every 60 seconds, the remote temperature/humidity monitor shows a 3 to 4 degree F difference between the tent interior below the lights and the outside room temperature. The back of the boards themselves run at about 120 degrees F under these conditions.The ability to link multiple lights to function under a single controller is a great capability. This may be an even more important feature if you’re leaving the drivers mounted on the boards, but accessibility is still improved by having the option. The linking process is intuitive, and you retain the modularity of the system if you really need to run the lights separately.As food for thought, I’m running some 4’ LED sticks on a shelf which provide a maximum PPFD of 300 at 12” in a 5x42W (~$85 purchase price) configuration for a nominal draw of 210W. I have an array of 4’ sticks at 20W (~$30 purchase price) each in a 6x20W configuration giving almost 100 PPFD at 12” in exchange for a 120W draw. You’d have to guess as to the nature of the spectrum, but neither provide infrared. If you spend even a moment crunching the numbers for measured efficiency, PPFD mapping, output adjustability and the resulting power draw, and the relative price point of these “cheap” lights and the HYDRA-1000, you’ll quickly find that the combination of overall capability, portability, adjustability and efficiency of the HYDRA-1000 really narrows the gap (or more than eliminates the gap) between cost and value when considering the nature of particular lighting solutions.Though I don’t personally consider it a necessary feature here, the HYDRA-1000 doesn’t support daisy chaining for electrical power. This shouldn’t be much of a consideration for small quantum boards in the 100W category due to their intended application, and the absence of this feature is covered by the use of a properly configured extension cord, timer or inexpensive adapter. I also wouldn’t want the price point or form factor to be altered in order to provide this capability. That’s my only “con” in the face of a litany of “pros.” I find the HYDRA-1000 to be a great product, and I have four more on the way.

I've been growing in a relatively small space for a couple of years now, using a cheap $80.00 grow light which wasnot only noisy, but it produced an excessive amount of heat in the small (2'x2'x44") space . I decided to try something new, and the Atreum Hydra-1000 is exactly what I hoped it would be!I received the light last week, and immediately put it to use...It came very well packed in an unmarked box (inside an amazon box)... Besides the light in the box, there were 3 stainless steel cables for hanging the light (you only need 2, they include an extra!), 2 adjustable ratchet hangers for adjusting the height of the light, a cable for daisy-chaining the control boxes together on multiple lights, a 6foot power cord, easy to follow directions, and a 6' cable for mounting the controls remotely (either inside or outside the growspace)Very high quality stuff, from the light itself, to the included accessories- Atreum has done all they can to make sure this light does a great job for you!I knew when I ordered the Hydra 1000, that I'd be mounting the control box and Meanwell driver remotely,because I've only got 40 inches of headroom in there- with my old cheap light, the light itself reduced the headroom to 37"- but the Atreum light with the controls remotely mounted, allows me to use the whole 40"-the light itself is, amazingly, only 3/32" thick, and passively cooled so there are no fans to collect dust and make noise-Here's where the 6' remote cable comes in- I wanted to mount the controls where they were accessible, but out of the way, so they went into the lower right front corner of my grow box.(see pic)The dimmer feature is a very nice touch- I'm running mine at 60watts at the moment, and I'll increase output as needed when flowering begins.The LED's are Samsung LM301B's- super efficient, and they'll last for years- they're also the reason that this lightperforms as well as an inexpensive light with twice the wattage- this thing is incredibly bright, and my plants are loving it so far!And the LED's are also not set in the usual grid configuration- they are actually spaced closer together at the edges of the light - this assures that the light is almost as intense around the "edges" as it is in the middle of the space-and it also eliminates "hotspots" in the center of the light- no one else does that- I think Atreum is really on to something with this change in configuration.Sorry I got a little long-winded here, but there really is a lot to say about this light- and none of it is bad!I definitely recommend this light to anyone growing in a not-so-big space- It will grow great herb start-to-finish in a 2'x2' space, or do a great job vegging your plants in a 3'x3' space- all while only drawing 100 watts from the wall- there just isn't any downside!Happy Growing!T.G.
