man sure sounds like alot of work to go thru and still take the chance of unstable genetics that could cause hemi's and screw up your entire grow sooner or later. why not just let your plants breed true. they way mother natured intended. it only take 1 male to pollenate an entire field of females.
my thoughts are if you germinate 100 seeds that you would have 99% rate of getting a females if you give them a stress free enviroment to grow in.
and breeding true and not dirupting the genetic make up of your plant will give you better yeilds and sooner later you will miss a hemi down deep in the plant and lose an entire grow to seed. some things are just better left alone
