Subject: Will crystals grown from iodized salt and uniodized salt differ?

Hello -
I am going to grow crystals from iodized and uniodized salt.  I am also going 
to use drinking water and distilled water to see if the crystals grow differently.
Will they grow differently because of the iodine in the sale? Can I see this
difference in the shape of the crystals or how many of them form?

I also would like to know if the pH balance of the water would make the
different kinds of salt solutions grow crystals differently.

Thank you.
