A little-known Canadian company just unlocked what some experts think could be the key to profiting off the coming marijuana boom.

And make no mistake – it is coming.

Cannabis legalization is sweeping over North America – 15 states plus Washington, D.C., have all legalized recreational marijuana over the last few years, and full legalization came to Canada in October 2018.

And one under-the-radar Canadian company is poised to explode from this coming marijuana revolution.

Because a game-changing deal just went down between the Ontario government and this powerhouse company...and you need to hear this story today if you have even considered investing in pot stocks.

Corinne Cardina: The first stock I want to talk about is actually the best pot stock of 2020. This stock is GrowGeneration. When I checked yesterday, it was up 892% year to date. Eric, can you tell us what this company does, and what its future might look like?

Eric Volkman: Well, first of all Corinne, I hope you invested in January and are now ready to retire. Yeah, me too.

GrowGeneration, they're a retailer, a hydroponics retailer. Hydroponics, for those who don't know is the act of growing crops without soil. There's a lot of equipment that's required for that, poles, pipes, trays, things like that. It's a very equipment-heavy operation and a lot of marijuana is from this way.

So, GrowGeneration as a hydroponics retailer, is in a good position. It's also, now that we've spoken about acquisitions, it continues to be an acquisitive company. The difference between it and your typical marijuana grower and producer is that they don't overpay for assets. They certainly offer attractive prices, but they don't go crazy. I mean, how much can a hydroponic retailers sell for, after all?

They're buying up smaller operations in places like Arizona, which we just talked about, and I believe Michigan was a recent one. Now, both of those -- Michigan has already legalized recreation marijuana; Arizona, as we've discussed is going to. GrowGeneration is buying in smart places, in places where there is and will be demand. They're positioning themselves to be if not the number one hydroponics retailer, at least a very familiar and identifiable brand in that segment.
