Gardener's Edge (NOT to be confused with the A. L. Leonard one) is always very helpful in the store and they have a knowledgeable staff as well as good hours. I've seen people drive hundreds of miles to come to them. I've been to other hydroponics stores who gave bad advice and poor customer service. This place prides itself on making their customers and their customers plants happy. Very professional and personable. Oh and they have a web store now too (with in-store pickups as an option, and live help). Now you can bypass the store entirely and get help online, order, and then go pick it up. Much faster and more convenient. Will shop there again!
