This is the Costco of hydroponics stores. You can grow anything or as much as you want from this store. They have a full commercial mock-up in the store that's about as large as many hydro stores' total floor space.
The manager, I believe her name is Bret, has over a decade of grow experience & has deep knowledge of the grow process. She is pleasant and generous with her time and knowledge with no expectation of an immediate purchase. She understands the value building business by building relationships.
There are also other knowledgable staff & those who aren't don't try to BS you.
The store will match any price of a brick & mortar store & work with you to approach online prices. That's good enough for me because the information & convenience make up for a marginally higher price, not to mention that it keeps the money here in Vegas.
