where to buy the nutrient solution

[Snake]

I want to do my 7th grade science project on hydorponics. I want to compare a plant grown in dirt
with a plant grown using hydroponics. Where can I buy the nutrient solution or do I need to make it?
Any help would be great. Snake

Hi Snake
You can find hydroponic nutrient solution at hydroponic grow stores in most major cities or you can
order some from the grow supply stores that are posted here on hydroponics online.
It's difficult to mix your own but if you want to try click here. Element Chart
