the guid to building a bubble bucket is good but mine is a simple method, no need to drill holes or buy plastic pipes

all you need is 1. a bucket minimum 5 ltrs
2. air pump (size depends on bucket capacity)
3. tape (must stop light getting thru)
4. mesh pot 6"
5. clay balls
6. sharp knife
7. 6mm air line
8. air stone

cut a hole in the lids bucket to fit the mesh pot in, then tape the lid and bucket to make them light proof, tape round the mesh pot also. put a small hole in the lid to fit 6mm air line through and seal round airline with tape fill bucket to bottom of mesh pot then add nutrients, put your cutting thats in rockwool into mesh pot with clay balls and switch on.

allow water to drop at least an inch below pot before topping bucket up to allow roots to breath.

i have used this method with a 55ltr bucket two air pumps feeding 3 airstones and have 4 pots in the lid and have seen very pleasing results under a 600 hps lamp in a 1mtr sq grow room in recent years
