Subject: Using 'Arnold' rye,wheat,white, which one will grow mold faster?

I checked your files and there is a question similar to mine but 
it doesn't say whether they used the same brand of bread.  Also,
I put dust from a fan (on a cotton swab) and spread on each piece
of bread, then added 5 drops of tap water (each corner and one in
the middle).  Will I get an accurate reading from my test since I
used the same brand of bread?  What would make mold grow faster
on one kind versus the other?
