I picked up a sweet 18 gallon black recycling tote from Wal-Mart for $10, very sturdy and it has a portion of the lid that flips up so I can see the roots. I'm laying out the design on paper so I can see exactly what I need. Amazon has great prices on pumps, water and air. I want to use drip rings but would I be better off using a drip nozzle that I can place right at the base of the plant? Thanks guys
