Remember you want to keep the silver off the others.
If possible start the "male" about 2-3 weeks before the others (12/12 switch since you've already got them all going) otherwise your timing will be a bit off. You should still get seeds if you have to do them at the same time but less and you'll have to likely run them a bit longer to let the seeds mature.
You can totally leave ":him" in the tent with the others and give him a good shake every day or so to spread the pollen, cut a branch every couple of days and shake over the others, plenty of pollen.
