Urban/Suburban Hydroponics system

Hey there I currently live in Champaign-Urbana, and yes it is big on agriculture, one might even say massive. Anyway, I have always wanted a garden I can tend to and harvest when the time comes but unfortunately I live in an apartment. Yup I'm a millennial in college no money and no assets and yet I want to farm. So I decided to try, and here's what I came up with.


  1. No space
  2. Ugly carpet
  3. Low window count
  4. Rent to high
  5. Yard is a poop mine feild
  6. I have to pay for laundry
  7. Bus never ontime
  8. Sleep is a luxury not a necessity


Solution! Build a garden in a window!

I decided to build the garden in a window because I literally have no space and actual sunlight ha limited range in my space. After putting it together it worked until I added the wrong amount of nutrients but anyway let me show you how it all worked out.


 1/4 in birch plywood

8x1 in plywood


PVC pipe and couplers ( depends on your setup )

1 x Sump pump

1/4 in Vinyl tubing

90 degree angle brackets


3D printer

Hack saw



Hydroponics: [hahy-druh-pon-iks] noun  the process of growing plants in sand, gravel, or liquid, with added nutrients but without soil.

The system:


The Reservoir:

Water enters the reservoir which is 2x the size of the Sub Grow beds reason for this is pressure equalizer. It acts as a water tower keeping the grow beds at the right level so not to flood plants the coupler/reducers block the water from going back and ensures the water stays in the pipe. evaporation is the only thing you need to worry about.

Sub Grow bed:

Hold plants and outputs water to next Sub Grow bed or bucket.


The build and fabrication process is very straight forward. so Here are pictures.

My favorite part is the k cup holders I 3D printed the lip on top holds a small k cup snugly and and grips the pipe without slipping.


Full Assembly

Well that's it took about 8 hours to build and it was very gratifying to see the plants grow until I added to much miracle grow. I was in the midst of adding automatic PH balances and sensors to make this an IOT project but when the plants died I got discouraged so I didn't, maybe it should have inspired me.
