When I got my first tree what I decided that I wanted to grow it indoors. It's safer and easier to care fore. So I headed to my local hardware store, and meandered over to the lightbulb section. After a bit of standing there, a guy came by and asked me if I needed help. Usually, I say no but I wanted to gtfo, so I asked him where their grow lights were located. The guy took one look at me and said "Ohhhhh I know what you're growing, I got just what you need :)", I told him I was just growing a bonsai tree, but he would not believe me. We talked about it for about 5 minutes while I was in the store browsing and he kept hinting about all the marijuanas I was going to go back to my house and grow, and even went so far as to say "You're lucky you got here today, we have a guy who comes in every other Tuesday and buys our whole stock, but don't worry, your secret is safe with me ;)" I insisted I was not going to use it for anything illegal, but he wouldn't take no for an answer. It was really frustrating.

Sorry about the long story, but I just wanted to say love it, take good care of it.

TL;DR: If you try to buy a growlight, they will know you smoke pot...no matter what.
