Bailey was super helpful! I work in the industry in NYC and while visiting was super curious about the store and their products, how the cannabis market is moving, and Bailey answered every question with grace and patience! They REALLY know their stuff here, not to mention the quality and prices of the products. Maine’s market is killer, and folks like Bailey and the whole SeaweedCo team are the reasons why!

Lovely experience here when we popped in while in Portland. Location was great and there was ample parking in the lot outside. The branding is so cute that I was tempted to buy the sweatpants and honestly would have if they weren't out in my size. After checking in with our IDs at the front door we were directed to the counter where the gentleman working there gave a brief overview of our options, asked what we were in the market for and then made suggestions based on our preferences. Was super easy and enjoyable.
