I'm from LA and looking to set up my aging parents with a grow. The owner (her name is "T") was amazing! She was extremely knowledgeable about everything in her store, and advised what would be needed from the ground up for both soil & hydro grows. She correctly stressed CANNA's products are the Cadillac of hydroponics, but pointed out relevant brands at every price point. She doesn't give a "hard sell" pitch; selling through knowledge. For Rhode Islanders looking to improve /fix their existing grow, or for those looking to grow for the first time, I highly recommend Liquid Sun.
