Any skunk or diesel strains will be low odor, as well as any cheese strains... Naw I'm just messing. Is it indoor or outdoor? You can pretty much scrog any strain, you just need to train it. I'm assuming its indoor, so I would just pick a high yield plant like like critical jack, grow just a couple, veg them for 2 months while LST and topping or FIM if you want then flip and keep managing the canopy with the screen everyday. But really, it all depends on your setup. Instead of trying to find a low odor strain, make a cheap $20 carbon filter
there are a bunch of DIY's for them in the General Marijuana Growing sub forum DIY. Good luck man!
