I agree with Sarah. My concern would be getting ripped off. Be careful about what other people see you bringing to the warehouse. Large bags of soil and such. I grow and my concern is getting jacked in the middle of the night by someone with a sawed off shotgun. It happens more often than you realize. I would also wonder about temps. Lots of warehouses I have worked in get hot as hell in the summer and cold in the winter. Good luck and congrats on the card.
