How do I start breeding ?

How we doing guys was wondering how to start breeding my own seeds to produce my own strain been thinking of doing it for a while now, just need to know the ins and out from one of the masters of the arts any input would be appreciated

most put opposite sex plants in flower at the same time, pollinate with fans when male flowers open up.
alternatively you could force a female plant to show male sex and use pollen from that source too, or the pollen that comes from
those yellow fingers in late flower sometimes.
first though you need a grow room that is completely controlled, temps humidity, pests, good moving air, lights air conditioner, timers, controllers, monitors. Without that its a crap shoot
