Mason jar Hydroponics system

Hydroponics system using 1 liter mason jar and PET soda bottle. I wanted a basic and easy design to start hydroponic-ing asap.

This little connector makes it possible. The pump I am using is USB connected and the rectangular whole is there for the wire to come through.

I now need to design the baskets for the PET bottle. Will post those once I have made ones that work.
[Edit]- I have made a Basket design. This one fits a 1 liter PET soda bottle. When inserting it into the bottle, leave a lip at the bottom of the hole you are cutting in the bottle to make sure you don't have water spilling. It mostly doesn't but I found that the lip makes sure of that.
