I am getting ready to set up a demonstration for mineral nutrition using
Hoagland's solution and hydroponics.  We have been using styrofoam tops on
wide mouthed quart canning jars.  The styrofoam tops are not entirely
satisfactory because they don't stay in place well, especially when they
get bumped in a crowded situation.  We've tried taping them in place but
the tops need to be lifted up daily to add more solution.  Does anyone have
any suggestions?  Thanks for any help.
