DreadedHermie Reviewed by DreadedHermie on . Procyon Breakdown I have a Procyon LED grow light that I have had a little under a year. I have been using it with good results. However, this morning when I checked my grow, it was dead. Any one know where I can get it repaired or is it just a dead paperweight ? Rating: 5
