A bubble bucket is a hydroponic method for growing indoors that is small and compact. It uses a  soilless medium and sprays nutrient enriched water on the roots of the plant to encourage rapid growth. Now lets get started...

We don't want light to pass through the bucket, so I use aluminum tape. Duct tape won't work. Light will pass through duct tape. Also its better to tape before drilling holes.Start by taping outside of lid. Completely tape the outside of the bucket. Do the outside bottom as well.

Step 3:

We now need to cut a hole in the lid to fit your mesh basket. The hole has to be about 1/4" smaller then the top outside diameter of your basket. If you don't have any good hole cutting tools, you can use a razor (don't cut your fingers off). Drill/Cut your hole in the center of the lid.

Step 4:

Its important to know the height of your mesh basket so you can position the fill hole below the bottom of your basket. After measuring your basket height, place your lid on your bucket. Mark your fill hole location about an inch more then your basket height from the hole in your lid.

You could also use bulkhead adaptors here, which might make for a better seal.  I got mine at a local aquarium supply.

Good instructable, it looks like a very effective design, I'll try it out later this summer.
