Built my own ebb & flow system. 2- 2'x3' trays. 15$ home depot. Pumps fitting from hydro store $45. 50- gallon roughneck storage bin $15 Walmart...boom that's it. Simple and effective...BTW..trays are 8" deep. Ill post a pic tonight. Easily saved $100+ bucks doing it myself. Also built a table out of 2x4's. $25 at home depot...MAKE YOUR OWN. U WILL THANK MEFOR SAVING U CASH. Any questions just ask. This works flawlessly.
