Info on this type of system by BA Kratky
It is called the Kratky method, developed by a professor from the Univ. of Hawaii. He found a setup that would allow you to grow the plants in a static nutrient solution without the need for aeration.

that foam does not look like safe to use for food. it has lots of chemicals.
who plays this song?
I have spent months studying home aquaponics and discovered a great website at Keiths Ponics Site (check it out on google)
This looks familiar!
You may save a lot of money construction hydroponics yourself rather than buying it.
this is really good. i was just wondering, can i grow tomatoes using this method? how often do you change your nutrient solution? or is it a one time pour of the nutrient solution?
would this material be to small to hold up the pots? I'm having a heck of a time finding the right size for a bus boy tote version.

The presentation… so much better than hearing people hem and hah! Very clear, pleasant music. Thank you.
Information… some really good ideas. Again, thanks!
The downside of hydroponics is you will need to purchase "plant food" or nutrition and supplements which are more costly.
what mil of film do you need?
Very cool can't wait to see lots of updates on this!
good scoop,my have to try that
Thanks for the info. Looks easy enough to build.
Great job, looks great and every easy to build. Love the kraky method.
You made it look so easy & simple,maybe just maybe someone like myself with NO carpenter skills could pull this off?? My husband Isn't handy & doesn't want to be.Just gotta slow ur vid down to write all this down. I got power tools & no skills. Thanks for sharing.
cool
