If you are a very experienced grower, you MIGHT get a total of 16 oz, if you are lucky. I have been growing a number of years, and doubt if I could do it. so I think you would do very well if you got say, 12 oz. Now how do you want to spread that out into number of plants? 6 plants @ 2oz would do it....
or does 12 plants at 1oz sound better?

Don't plan your yield unless you've done it for a few years, that's my advice, your first crop... hm maybe 6 oz?
