hey chris this is what i do and for me its ALOT cheeper than buying the hydrofarm like buckets......
just find some company that uses buckets and ask them to save you some (if your worryed about why just tell them to store pet food in so mice dont get it or somthing like that) but anyways then go buy "net pots" for your buckets cut holes according to your net pot size in the lid of your bucket and a lil port for a air line (also you will need a air pump & air stones) and there you have it a extra cheep dutch bubbler (i get my buckets from a ice cream place nice clean food grade buckets )
