Hi Shaun!  I love the round wire fences that you are using.  I assume they are for the ambient plots.  What exactly is that material called and where can I get it?  I’ve been wondering what I could do to enclose my ambient plot without affecting the results of the experiment and the round wire fencing seems to be a good solution.  Also, what are the hula hoops for?  Do they mark something special or are they just a boundary for your planted seeds?  I was also thinking of using a hula hoop for both plots to give the students a frame of reference as to where the seeds actually are planted.
