what kind of hydroponics is being used ?

I was wondering about those grow videos on the growhd.tv site that Greenhouse seeds do ? They have side by side hydro vs organic soil grown grows. For some reason I cant figure out what kind of system they have for hydro and was hoping someone did and could let me know ? thanks a lot for it -

what video are you talking about i cant find it

got a link

it looks to me like a giant dwc bucket

actually it is just a simple soil less mix that they hand water and the organic plant is grown with organic compost and no nutes just a little bit of bloom enhancer

right on thanks it makes a big diff apparently huh ? the hydro plant was insanely bigger
