Answer the question you selected for profile question 3 here (300 words):
Don't doubt your instincts. I noticed that something was wrong with the light levels in a growth chamber that I was using, but assumed since it was programmed by someone I really looked up to, that something must be wrong with my eyes, and not the way it was programmed. Turns out, it was the chamber, and 3 months of data had to be thrown out. If I had trusted my instincts, it could have been avoided.
