Which is better hydroponic weed or organic grown weed?

Some say that hydroponically grown organic weed [is] the best.

"Hydroponic" refers to a method of plant growth without the use of soil.

"Organic" usually refers to the reduction or absence of harmful botanical materials, especially pesticides.

It isn't a choice between one or the other, and a plant could be grown organically in a hydroponic system. However if you had to choose, organic grown weed would be a good choice, as it is helpful for the environment and contains less harmful contaminants.
