I bought 2 of these to start my grow with. I figured I'd open one to see what's inside so I'd have the info to see if there were better cobs I could put in. Unfortunately, I'll need to take a cob off the board to see exactly what those are, which I won't do until I have more lights so I can have one of these down for a bit.
Anyway, for those interested, here's what inside.
