Why build the Percolator?

I had a subscriber on You Tube ask me a pretty straight forward question. He basically asked, why build build the Percolator when a bubbleponics system would be so much easier? Couldn't you just put a hole in the lid without the PVC pipe and add an air stone? This in part was my response.

  If you wanted to build a bubbleponics type system you would not need the PVC tube at all. Yes you could just drill a tiny hole in the lid and feed the tube through it, no silicone necessary. I did not want to build a simple bubbleponics system.
This is a variation of a top drip system. It was made to eliminate a few issues I was having building an inexpensive home made system.

How to make a Top Drip Bucket Hydroponic System

This video contains instructions for building your own Top Drip Bucket Hydroponic System using a 5 Gallon Bucket, a Mesh Pot Bucket Lid, and the GH Farm Kit. This kit was intended to be used for the General Hydroponics Water Farm System. I knew with a little modification I could build my own system and save a few dollars.
The Pumping Column is an "Air Lift Pump". It uses air bubbles instead of an electric water pump to supply the hydroponic nutrient to the plant.
I recommend you buy the 10" lid. As you see in the video the 8" will work also with a very easy modification. I'm using this system to have my own home grown heirloom tomatoes.
