Science Buddies: "Ask an Expert"

Hi, I'm planning to conduct a project on grey water through a hydroponic system growing amaranth. I know I need a nutrient solution for the plants to grow in. Due the the fact the grey water needs to be changed every 24 hr (to reduce the rick of bacteria build up) I will need a large amount of nutrient solution. I need a reliable "recipe" for the nutrient solution. Although I would love one catered to amaranth's growing needs, a standard one will do perfectly. Thank you!

Hi!
Sounds like a really interesting project! It seems like there are a lot of good "recipes" out there, I found a couple links that I thought might help you"
