Hmmm...Jello for plants. :)  Interesting.  Agar gel is a long proven and 
effective nutrient medium.  I cultured many a bacterium on it in 
college.   It would have several advantages over the usual methods.  Can 
anyone think of any drawbacks?  How would the gel behave over time in a 
submerged environment?
