Grand Master LEDs

Grand Master lights deliver powerful grow lighting built for indoor growers who demand precision, durability, and high output. Known for their multi-channel spectrum control and water-resistant construction, these lights give you full control over your environment from seed to harvest.

For the best PAR consistency we have ever seen on a grow light with added diodes on the edges checkout GML's 4x4 and 5x5 tent grow lights.

Popular Grand Master lighting picks like the Tarantula Borg Evolution V2 and V3 offer intense full-spectrum coverage with Samsung EVO diodes and customizable tuning. Grandmaster LED lights' Tarantula Voyager packs the same top-tier performance with added versatility for various grow spaces. Expect unmatched consistency, rugged build, and proven results in every fixture.

awesome company

I mean, what can I say everything I’ve gotten from Rosineer is awesome so I mean really all I can say top-of-the-line I love it. I love it. You don’t have to hardly put anything on it. To press is so nice once again guys you knock it out of the park. I love it. I guess the only thing I can say is we wish you had your own filteris awesome so I mean really all I can say top-of-the-line I love it. I love it. You don’t have to hardly put anything on it. To press is so nice once again guys you knock it out of the park. I love it. I guess the only thing I can say is we wish you had your own filter bags that matches the block blocks and I have every size thank you so very much and fast shipping.

came broke, missing pieces, & impossible to assemble

Came broken and missing pieces but the company was quick to send new foot pads and the missing pieces. Once the company sent correction it was still not possible to put it together as the bolts were not long enough to screw in and there were no instructions. There are two spaces for bolts to hold the leg piece on, the top opening has a drill out to let the bolt pass through and screw in fully, the one below does not, making the bolt too short to touch the body of the equipment.
