24.
Marijuana which has been grown indoors using lights and chemicals. Quite dangerous as the grower usually does not take the two weeks required to "flush" the plant on water alone, thus removing the phosphors and fertilizers out of the plant, so the smoker will quite likely suffer mental problems, possibly even after a short while but will suffer them eventually. see weed, ganja, chronic or bud etc.
I think hydro weed is dangerous shit, i would like to nail irresponsible growers to the wall!.

Marijuana grown indoors using a hydroponics system (tubes and filters with water and fertilizers). To correct the first definition, NO marijuana causes mental problems - but it does get you really high.

Hydroponically grown marijuana of good quality. Often called "hyge" for short.

Hydro is a better type of marijuana because you will get a more enjoyable high when smoking it. For example smoking regular weed will make you tired.
You will know that you are smoking real hydro because the ash will be pure white, not grey like shitty weed.
