I really like this question!!
MPD is a specific type RDWC that is not UnderCurrent, however I run a MPD type of system where the buckets are connected with 2" PVC which makes it UC but the room setup and design, veritcal bulbs etc is all the same as MPD.
A local grower is getting 2-5 lbs a plant with a very similar MPD style system that uses 2" pvc to connect the containers making it UC which I emulated for mine.
The Current Culture systems you can buy commercially are getting great results but they are not being marketed for use with Vertical Bulbs and I feel would do great in supporting an MPD type of system.
I would say you could get similar results with MPD or UC as long as you know what you are doing but it seems it may take 3-10 crops to even get over a LB per plant unless you are a hydroponics genius and already use to getting those types of yields.
UC has a lot of benefits to MPD with the best being less pump requirments, less need for water chiller, using gravity, faster water flow.
For me trying to combine UC with MPB has been similar to chaising two to rabbits at the same time and not catching one as I have not broken the LB a plant barrier after 2 runs.
I would recommend following Double LEDs advice as much as possible until you get your yields up to his levels.
As far as container size with 5 gallon buckets by the end the bucket is 90% filled with roots so you really are best with something around 10-20 gallons.
No point re inventing the wheel or trying to outsmart nature...
Good luck friend!
UC told me my large Tanks were useless his 13 gal buckets were tits. After seeing my 36 gal tanks kick their ass they changed their tune. I would not run less then 25 gal tank. there is a reason. Suerte JK
okay, i give up, what's a mpd?
IMHO, its no contest....UC all the way!
Im sure I wont win any friends with this post (and apologize in advance for all I offend or who runs a MPB system...Im sure there is always a place for every system), but I must be honest.....The MPB seems like a very wasteful over complicated design.
If I were at work with my fellow team of engineer's and we were presented the design of the MPB to scope as we do with so any different projects....I could see us scrapping about half the parts and ending up with a redifined efficient design that would prolly end up looking alot like the UC design I imagine.......efficiency...just cant get past that part and how IMHO the MPB design lacks it......and the UC system is superior at it.
PS- I would also love to see one of these elusives JK systems but have given up after seeing so many folks denied when asked....I wonder how a person who wants to buy one gets one???....seems damn near as bad as trying to get a med card...ROFL.....as a builder/designer/engineer for the past 28 plus years of RDWC designs I cant help but be curious....pretty sure all the trade secrets are either already known by now or are in no fear of being stolen...rofl..some peoples kids...lol...how much harm could some pics do anyhow......I dont get the secrecy but then again I dont get alot things....hehe
