I am doing a science project on the growth of plants using hydroponics. I am 
using a hoagland recipe as a nutrient solution. I need to know how often I 
should relpace my solution when I am using about one liter per bean plant in a 
two liter bottle with a small airstone placed at the bottom. Thanks!!
