I went by this hydroponics store a couple of times and there were only one customer in the store. I started talking to him about the fact that no one was in the store and he said the owner gets most of his customers via the internet store. He said that most people will not come in to buy because a lot of times the authorities are watching and will investigate the buyer. He said they immediately suspect marijuana growing. I told him they could come to my house I have nothing to hide, all veggies. It's a same that you can't just garden and not be bothered. I read an article on the internet about this elderly couple that had bought some hydroponics equipment and had a swat team raid on their house. They found like 3 veggie plants. They said the couple is suing the sheriff department.
Lousy for Hydroponics Veggie Growers
I haven't heard of anything like that in my area, nor have I read any articles about that. Either way it's never stopped me and never will stop me from going to my local store. Sometimes I go there for stuff for my fish tank. I don't believe there is any cannabis coral lol.
My store almost always has nobody in it as well. I would think that growers of illegal herbs would prefer to pay cash.
Bottom line: if you have nothing to hide then you have nothing to worry about
That's why I said they could come to my house, I have nothing to hide. I posted a site referring to the swat raid.
