It seems to me you can't go wrong with a type of board style white light array in a small space. Those old slug blurples just run far too hot for that application and the space savings are huge. Its really not that much more of an investment and if you decide to not grow MJ anymore you can still use the light elsewhere like your kitchen or garage or sell it to a fellow grower. It seems the concensus is return the light and get something that will better suit your needs. You don't owe it to that light "to see what it can do". It's garbage, thats why it's so cheap. Not trying to be a douche, just sayin. And so is most everyone else.
