I am growing white rhino right now and very impressed with it so far. I bought them off amsterdammarijuanaseeds.com last year as part of bigger order.
Odor hasn't been too bad though I vent to the outside and have hanging bags of activated charcoal in grow space.
Pics of my rhino from the other day attached here:
