It basicaly a really wide nft system (mine will be 2.5 - 3 ft x 6)
Where you form a "meniscus" film in the bottom
Using a batting as a wick material to help form the film of water
If you dont use the batting the water will just flow down hill in the path of least resistance.
The batting uses waters surface tension to hold it in a few mm thick film.
Where your roots can lay down a base of wet feeder roots and being surrounded in a dark moist chamber
It uses a very little amount of water.
Originally developed in Australia to grow food where the water is limited and so is the power.
So it can be fed from a raised barrel and not use power
Its also basicaly media less besides the batting and what ever you start you cutting in ill be trying to go bare root so i have to buy nothing except more batting
no root rot do to high air volume.Panda covers the root chamber

Im currently (well half ass lol) testing a nylon i think it just cheap batting about 1/8th to 1/4 inch thick
It seemed hydrophbic the first few time i tried
I thought fuck i need to find somthing eles
But after a few waterings it soaks up like a sponge ...so i may run the full size version through a wash cycle first
That system is stupid simple thas why i want to try it.
The one that im racking my brain on is how toake a seed running table that i can constantly pull out of the system roots and all.
But i want it to be media LESS just a net cup or collar preferd basically a containorized hydro setup that is fed from one res but made of individual cells if that makes sense its late lol

Only thing i've found regarding this system:
http://hydroponicsociety.org/massive-tomato-yield/
looks promising as i was expecting the usual lettuce grow but nope, this guy grew heirloom tomatoes.. and quite a lot of them too...
as a rule of thumb if you can grow full size tomatoes you can grow weed.

Boom your a smart one
Look up how major ag grows tomatoes......none use rdwc lol mostly drip feed in rockwool or other methods

I had a vid link but look up flood and drain the easy way
(Even though its a hybrid of flood and drain
Im almost positive he got the idea from the meniscus setup

heh ever since i posted that i've been non stop researching to find more info about this, apparently Andrew Parker the inventor of the membrane meniscus system had a website entirely dedicated to the system called http://www.membranemeniscusmethod.com, this site has unfortunately shut down in 2017 and all that remain is its waybackmachine snapshot:Boom your a smart one

this site offered a free download of Andrew's e-book "the new hydroponics" which is now unavailable as a result, from there i've found a blob post from a guy attempting to grow some leafy greens in this system but the blog is from 2016 and there are no updates since, also a bunch of comments asking him to send them a copy of the pdf if he has it.
did find the video of Andrew's tomato grow on the Hydroponic gardening society of victoria facebook page where he was a member:
need to get my hands on that ebook

Look in the journal section for three differnt hydro system on one pump.
Me and the op discuss what we knew and i think he found that book
you dont say..

Just cause i always make my systems my own.
I rarely copy others work to a t .
but find ways to make it mine
Theres a few tweaks i got in mind .
But as said my head is wrapped on my seed tables atm .
But i have about 2 or 3 differnt versions of the meniscus designs thought up
