i used a 3gal bucket, with lid. two 3" holes in the lid for baskets i got at wormsway. a tube at the bottom of the bucket to drain back to res. i use a 5gal bucket for a res with a air stone and pump. i pump to a six way splitter i got a wormsway one drippier for each basket(2per bucket). i chained a few of these together. supports 3foot plants easy and one plant per bucket 6foot easy. most of this stuff i got at work so cut down the cost, but still pretty cheap. just an idea, any of these listed here would work great. btw in the baskets i use 1" rockwool cubes with some lava to hold in place. less media = less cost.
