Well it'll be good if you're not lookong for a big yield but I can say, having grown with htg led lights, that they work. Once I upgraded to those Area 51 lights it really put those htg lights to shame.Yes the black 1 is the 1 I got. Thank you for the heads up. Leaning towards doing a very mini sog with a couple 2 or 3. Im not really looking for a lot of yield it just for my use.
