I like the idea of a flat panel light assembly so I purchased five Root Farm LED lamps. For the Root Farm LED to grow plants Root Farm recommends the LED lamp To be on for 16 hours. I returned four because the supplied power supply get hot after the lamp is on for one hour. The surface of the four power supplies measured somewhere between 112˚F to over 120˚F. I called Root Farm and they stated it is a class (2) power supply and it will get hot. The lamps do grow seeding, but the power supply get hot, beware. I kept one because I'm going to try a heftier power supply and see what happens.
I purchased four of their hydroponic-garden-system. Each one had the same identical broken tubing. How did each of these pass quality control? I could have fixed them, but then I started thinking what else didn't their quality control find.
