Here at Green Thumb we're called hydroponics experts for a host of reasons. One of those reasons (many, many, many reasons!) is we know what we're talking about when it comes to lighting.
LED? Check.
Metal Halide? Check.
High Pressure Sodium? Check.
Look, if you're not 100% which of our light systems, grow light ballasts, reflectors, timers or whatever works best for your hydroponics garden ask us! We'll hook ya up. I promise, you're going to like the way you look - I guarantee it! (Oh hell, that's not the right tag line is it??)
