Yep there's only 1 problem with your theory that the pro's do
I got a funny feeling you're rehashing something you've read or heard
One reason ppl grow out from seed is obviously variety , hut there is also another reason , you certainly don't want to go through all of that just to find that you've just spent the last 4 or 6 months cloning a batch of useless hermies
One reason the " pros " clone a Stable plant that has been grown out to full maturity ensuring it has the desired traits and doesn't hermie , now I know a lot of the pros don't do this because they sell fem or reg seeds that are indeed hermies , so they probably do exactly what you suggested
After all they don't give a fuck it's all commercially grown for profit or seeded for profit
A true pro would grow out the mother and a female of the father to full maturity, just to make sure they had desired traits and none unwanted traits , then would combine both strains obtaining seeds , which in turn would be grown to full maturity
If a a good sample of these seeds were tested , found to be successful and carry desired traits and most of all is stable
Then you would be safe to clone , assuming seeds you buy from any vendor is stable could be a very costly assumption on your part
The OP that you tried to school is that far in front of where you are assuming his journey is at you made a fool of yourself
To assume the community needed your valuable input was again a bit silly on your part , to assume that there isn't a active pollen checking group , that is pumping out some quite outstanding gear would again be silly on your part
So thanks for the lesson but as old fox said , how about you put up some pics of your "pro" set-up
By yhe way here's a pic of a bud from 1 of old fox's fem seed program, which I have 2 running about 4 weeks into flower
This what you are aiming for , a stable fem seed that has amazing trich count already frosty as a snowman
So before you lecture someone , you might want to check out their profile/ diary etc beforehand
