What's the best way to make high quality Cu(II)SO4 crystal?

    My high school chemistry teacher tossed us the task and told us to figure it out ourselves. As far as I can understand, the trick is to supersaturate the solution, put a seed on a string and hope for the best. I'm just posting here to ask if anyone happens to know any good sites I might not have found or knows some intricacies of crystal building, such as what makes a good seed, the optimal lighting conditions, if any, or optimal string arrangement.

    Light shouldn't matter. If you grow a crystal from the saturated solution the most important thing is temperature control - you want the solution to cool very slowly.
