So about 2-3 weeks ago when I updated my grow rack I bought a second 2x 2ft fluorescent ballast. Already the first small section of both bulbs in it have burned out, and I think that has caused both of them to dim. Is the ballast bad? Some bad bulbs? I will say that it gets humid in the rack, but this hasnt cause problems for the older, identical ballast before.
thanks,
