Recirculating hydroponics typically reduces water consumption by about 80%. For medical users in particular, indoor weed is safer, cleaner, and more consistent in quality.

Outdoor full sun organic with local inputs is the most environmentally sustainable way to grow cannabis. There is no data supporting the claim that indoor is safer or not, cleaner or not, and more consistent or not in quality (whatever "quality" means, quality is strain dependent not indoor/outdoor, usually refers to "bag appeal").

On the other hand, WA cannabis is mostly grown indoor, and the objective should be how to make indoor more environmentally friendly. Also, indoor growing in Seattle, for example, helps balance the grid by running lights at night, so carbon tax ideas would have to have data to be able to take this into account. And there is no such data.

They call it "dope" for a reason. The Stranger actually wants to ignore the energy impact of growing dope indoors. You people are such blatant idiots.
