Silly me! I thought 420 was 20 April, which is Easter Sunday this year. Little did I know that 420 has significance for pot smokers.
From the article:
Weed-loving treehuggers, take note. Cannabis production is increasingly moving indoors, into large-scale industrialized systems, and all those grow lights and air filters consume an extraordinary amount of energy. In all, marijuana grown indoors is responsible for a whopping 1 percent of the entire nation's electricity demand. That's enough juice to power 2 million homes. For 4/20, a date we hear has meaning for marijuana enthusiasts, we take a look at the power it takes to grow all that pot. Sorry to harsh your mellow, but that's a big carbon footprint.
