His system is technically still a Recirculating Deep water Culture, just the circuit is smaller. But I understand what he's sayin.
I will try to be brief.. lol..
One MAJOR thing that dd's system had over mine is that each bucket it individually filled and drained if that makes sense. One bucket is not dependant on another bucket functioning with dd's where with rcdwc the nutes flow from one bucket to the next. If one bucket fucks up, they every bucket after that is fucked up. Not with dd's system. Also a big thing about dd's system is airation.
If you look at my MPB thread as opposed to my Tub girls thread, you will see that each tub has 2 waterfalls from the drain tubing into the drain, then the drain waterfalls into the res and right back to either the chiller or to the plants. Both systems use airstones, so thats not an issue..
DD's system is modular.. That alone is huge. its not a pain in the ass to hook up a few more tubs if you have the light. Its easy to clean..
The bottom line is refinement and ingenuity.
Both will yield. DD's for the effort will yield more. :anim_19:
yes, DD has central reservoir, but I think he was referring to flooding issues with water spilling. DD has a check valve on the feed line, so if something went wrong the buckets would still hold like 8 gallons of water each and basically turn into DWC.
