Hey guys been lurking around for awhile, I just moved to a new place and finally can start up my little home project. I used to run a straight DWC 5 gallon buckets and had a heck of a time changing out Res and training the girls. Anyway to eliminate that I’ve decided to go with an RDWC system. I plan on having 2 grow buckets with an epicenter. I’m going to use an old college mini fridge to create a chiller and wanted to use an under current with the waterfall effect to eliminate the need for air stones. Now do I run my water pump from my epicenter/res, to my chiller, then T it off and run it to the top of both of my grow buckets to create my DO in the buckets through waterfalls. Or do I just waterfall my epicenter? And create my return line from a filter tube in my main pvc line? The videos that explain these always use air stones. Any links or resources you guys have would be awesome or just general advice. Thanks in advance!
