not sure what you mean by season but it is certainly possible to yield a pound per year, even growing from seed with about 3-4 harvest a year from a 400 hps.
if you have a seperate space or room to keep a mother plant or 2 and a place to start clones you could easily double your yield per year and use a higher yielding method of growing such as scrog or sog using clones where you might get 5-6 harvest per year.
