There's plenty of strains that will work fine, I would suggest fem seeds or sexing them first so you don't have to worry about them getting pollinated. As far as stealth, just find a good spot thats somewhat hard to get to with plenty of green around. You can tie them down if height is an issue, which will disguise them a little as well. I would look for strains with the shortest flowering times that are mould resistant. Also, you may want to check out some of the autoflowering strains. You can actually get a couple crops in a season with them. They got a few more crosses now, its not just lowrider anymore.
