Hello Sysprog, you pretty much got it. I only went from 3" to 8" net pots to buckets cause my timing was off, when i get things dialed in better i will be going from starter cube to net pot ( or 4" rockwool cube ) to bucket, eliminating one of the "tranplants" if you will. Also the system drains through the pump, you want to avoid any syphoning effect by drilling 1/4" hole in the top of the overflow ( see photo ) Without this hole it is possible that the system will continuosly syphon without draining. I also recomend a small recurculating pump in the resovior to keep the nutrients constantly curculating. Let me know if you have any more Qs. Have a good day. peace,Bonzo
