I have a rubbermaid DWC system and want to fill in some blank space with hempy buckets but want to find, I guess the most space saving pots/buckets, like 2 or 3 liter bottles, but not actually bottles, just something similar in size and shape.
My tent is actually so small I had to catty corner my DWC system so it's triangular spaces I'm needing to fill so this one will call for round, great idea for next go round though.
