There is no hydroponic specific plant... hydroponic is not a type of cannabis just the method in which it was grown. There is Soil, Hydro, and soil-less...or a combination of one or the other.
As far as high yeilding strains... there are many out there... just do some searching. You shouldn't just be worried about yeild.. and potency. Flavor, taste, and how long the high lasts, along with what type of high, can affect your decision on on what strain is the best for you .
Not to mention your grow area can affect the type of cannabis you should grow . If you got a small area then short squatty indica's are your thing.. If you got a larger area, sativa's may be your best bet(even in the yeild department). If you got a grow area that is somewhere inbetween maybe a nice hybrid as most plants are will suit you.
By reading the descriptions of the strains you can determine what is best for you and your area.
