Today in Quartz membership: Charts and the future of grow lights

Hi there, Quartz members!

Weed goes legit

Weed is growing up. Not only is it becoming legal in more places, but it’s paying taxes, attracting older customers, and spending more on political lobbying—it’s even on stock exchanges. Our chart book tracks its evolution. Also, we look at how weed-growing technology is advancing at a rapid rate, and how it will inevitably trickle down to more conventional crops, which could lead to innovations in indoor agriculture.

Our toolkit’s next

Friday, we’ll have all the resources you need to follow the fast-moving cannabis industry. Stay tuned for websites, Twitter accounts, newsletters, and much more to continue your education.

Let’s keep learning. Send ideas, questions, comments, and full-spectrum LEDs to [email protected].

Hope you have a rewarding day,

Sam Grobart
