This works great, been doing it for years.
Just remeber, if you have used any chemicals (other than declorinator), don't use that water for the house plants. Don't know if I even need to say this, but no water from brackish, or even if you use a little aq salt.
In regards to smell, if you store a bucket of gunky water it may smell after a couple days, or it may not. I've never had a house plant get smelly from using tank water. I just use it straight out of the tank, never keep any around, there's always more if I want it!
