I have all the parts to put together a DIY hybrid AERO/NFT/DWC system, for plants to veg only in, and be trained prior to being moved into an RDWC scrog flower system.
I have 5x5 fence post sleeves for the rails, and ez clone misters with a 1300gph pump to blast through them, and using 3.75 inch netpots all the way through the grow, so thats what they stay in since clones and fit right in the RDWC sites too. I was designing the rails to be tilted flat towards the last week of veg, and able to raise the drain so the rails fill with water at the desired heights. Also will have 1/2 soaker hose sections as the air stones.
I figure if im using aero/fog to clone with, then into the aero/nft/dwc rails to veg, and then pull the plants out before the roots get too long and plop them right into the DWC containers. But in a slower way that helps the roots make the transition. Also I won't be flowering with the aero which could be more finicky to dial in during those times. Just use it for amazing veg growth, then into RDWC for amazing flower growth as well.
I never really set it up because I was always just using whatever tubs laying around to veg DWC style with.
