surprised no one got back to you yet. AM2 is great, really fast and super good buzz. You could leave it in a sunny windowsill. It wont get very big, and you wont get the yield you expect but she is a nice one. After the direct sunlight is gone just use a cfl light bulb on her, Warm white at the highest wattage you can find. Not familiar with Mi5 so I cannot comment on that.
Good luck and hope all goes well for you.
