how do plants get the carbon necessary for them to grow?

[arjun]

Hi, I have some free time this summer and I want to try growing a plant hydroponicly. I don't want to spend a lot of money because I don't have much, ha ha ha. Anyway, I want to do this in a water solution. Anyone give me some tips or links to where I can find a picture or plans for a 1-plant aqua hydroponics setup? Thanks.

Oh, one more question...how do plants grown hydroponicly get the carbon necessary for them to grow?

Thanks: arjun

Chlorophyll, the substance that gives plants their green color, converts carbon dioxide (CO2) from the air, water (containing nutrients) and light energy into carbohydrates and oxygen. This process is called photosynthesis. What results is plant life. You then eat the carbohydrates and breath the air.
