I've tried afghan kush myself mate, I found it pretty slow to come along in veg growth....but then again i was using LED lighting...... With regards to smell, i would invest in carbon filter and extractor fan, after a while the plants (even 1 or 2) will start to stink out your entire house. the carbon filter is the best way of dealing with unwanted smells.... I found a pretty reasonable one on ebay from kitbagshop...
