your going to need roughley 2-5 gallons pere pant.. Easiest cheapest way in my opinion is
2- 5 foot long pvc pipe, 6 inches in diamter. Cut 10 hole in each pipe for the pots $20
a ruber maid tote around 40 gallons $15
a good water pump 500gph or better $80
air pump and stones-$30
sprayes are cheap at home depot $10
Thats just to get you started, im blitzed and tired...
Prices are just ball parkin, pvc is a good cheap wayy to build big
