Ok, so I'm a nub and I'm wanting to set up a DWC system. I am watching videos and reading everything I can about water, distilled water, reverse osmosis, ph, beneficial bacteria, lava rocks... wait... this is starting to sound exactly like my 2000+ gallon koi pond! I have 4 50 gallon barrels filled with lava rock plumbed to the pond. It took well over a year to get the beneficial bacterial cycle going, but now my pond is crystal clear and has been for a few yrs now. Now I'm thinking of the plants I have on the ledges of the pond. (not cannabis) sitting in like 2" of constantly circulating water, growing fantastically... roots everywhere... wait... this sounds like DWC! So, instead of all the nutes, ph tests, water changes etc., why not just plumb the dwc system into the pond system? Sounds reasonable to me, my pond is wanting more plants to remove the nitrates caused by the fish, and my plants want the nitrates to grow! Sounds like a win win situation to me, or is my blonde really really showing? View attachment 2083208 I now see (duh) this method is used... aquaponics... who'd a thunk... I suppose there are a million forum posts out there for me to put on my never-ending list of stuff to read. I suppose I could just ask what anybody right here right now thinks?
