I keep threatening to set up a grow room and will finally go ahead and do it this winter in my basement. I'm leaning towards a 4x4 or 6x6 room in order to grow for personal use. I'm a retiree and own my home in a typical surburban development. Here's my question: what can I expect in the way of odor from this operation? I can vent the room outside, but what can I expect the smell to be like? Noticeable to the neighbors or someone passing by? Same for the basement. Aside from the appearance of the grow room/tent, how bad will the odor from the maturing plants be? I'm thinking furnace repairmen, etc. coming into the basement. From the few times I've grown outdoors I know the smell can be strong.
