Ive been roamong the net looking for ideas on how to build a bucket system and liked both Rumpleforeskin and Budslinger's bucket systems but came across the bucket farm sets on eBay and thought what the difference in cost would be? If I were to build my own 4 bucket system would it be around the 140 it is on eBay? Thanks! I'd post a link but it automatically connects to eBay mobile as Im on my phone. If you search "bucket hydro" on eBay they'll come up. I think the price is fairly chrap but maybe you guys will see or know something I don't.
