I started with 2 x TS600's (mars-hydro) when I came back into the grow game but they quickly became not enough...he could probably get something out of it by supplementing daylight from a window or just put them outside some each day....but if he's looking for fat buds.....don't think it'll work........a lot can be done with home built , off the shelf LED set ups if he's looking to scale up slowly ( ie budget) and think there are a couple tutorials on it. best of luck to him.
