Very potent weed with a strong and pungent smell. As the name suggests, it gives a powerful high. Strains that could be considered power plant are Death Star, G13, Blue Dream or Sour Diesel. Really any strain that has been perfectly and meticulously maintained during the growing and draining process.
"Yeah man, I normally have the good stuff, but from time to time that power plant comes around and knocks everyone on their ass."
"Bro, I'm about to roll some fuckin' power plant."
