The brand founder and his top local farmers visit a dispensary, pick up a few and then hold a special smoke session. Plus, a third-party weed connoisseur samples the strain.

Epsiode 6: Time to chop down the Zpectrum plants. Then launch a curing process to dry, trim and package the yield. A pot farm this big produces an enormous amount of odor, which is still taboo, even though weed is legal. The perfume plants release during harvest is unavoidable, and perhaps the most pungent.

Episode 5: Only five Zpectrum plants remained by the end of the last spisode. And they still had a couple of days left in the vegetative room before moving to the longest phase of the grow-process. The founder of Alien Labs talks about growing as a professional to better deliver his passionate message on quality.

Epsiode 4: The six tiny Zpectrum plants grew roots by the end of the last episode, but still had a couple days to survive before they could go into their own pots. The lead farmer had to move cross-country for a chance to scratch and claw his way into the marijuana industry.

Episode 3: At least some legit weed companies in what prohibitionists might call this Brave New Arizona don’t plant seeds. Meet and greet the freshly cut clones that Matt Casey aims to follow until they’re ashes.

Episode 2: Get set for a crash course on marijuana-specific terminology used in this podcast series. We’ll also explain the genetic makeup of the plants we’ll be following.

Join senior field correspondent Matt Casey for a series of episodes based on exclusive visits to a huge indoor pot farm, learn about the growing stages, and get to know some of the people involved. The first episode of Reefer Growing Madness debuts Wednesday, Feb. 19, wherever you get your podcasts.
