Or do you have to fill/drain each bubble bucket at specific times? If so, how often do you do this?
Can someone explain the fill/drain/watering part of the bubble bucket for me.. pretty please?

I have found using a res for the Bubble Bucket system is bloody important, as the plants grow, the root mass takes up a lot of room in the buckets, so eventually you can only get a few litres in the bucket, the PH swings are also insane due to lack of water. A nice big res and you will hardly notice PH swings.
Its allright when they are small to just use the bucket, i find my 20litre buckets are totally full by the end.
The fill drain, i basically just keep topping up my res to keep the nute strength and PH perfect. About every 20 days i will do a full flush of system, quick clean, and start again. I have no idea if you even have to flush but i am sure salts build up.
Hope that helps.
