Didn't realise posts had to be approved so this is similar to previous post.

Growing under my desk. 200w light (enough for 1plant at a time?) Got mylar tape coming and a small fan. (Using tower fan during day atm) Parents used to me smoking and keep a half z on desk at any given time. They never come in my room. Will they notice the smell of 1 auto? Will ONA gel in my room work or should I get an extractor with carbon filter? Can't have it venting outside but could recycle in the space.

Any advice on how to improve? Thanks
