yes, why keep a mother though? here what i would do......set up seperate vegging and flowering areas (which you probally did already since you wanna keep a mother), then veg the first plant generation till your ready to flower, about 2 weeks b4 you plan on moving them into the flower chamber take 2-4 clones from the bottom of the plants and carefully mark which clones came off which plant. after sexing the plants in 12/12 kill all males and clones that are male. by the time flowering is done the new clones should be rooted and vegged and ready to flower, take 2-4 cuttings off each of those just like you did with the first plants and then just continue the cycle.....
