The other way would be to keep one known female plant on full veg 24 and 7 (never let flower) and simply take clones as needed from the mother.
There are "clone" tents available for this that top out in height at 2 to 3 ft.
And yes, in theory I could continually take successive clones but I'm willing to bet mutations would slowly creep into the line until it became nonviable.
I'm still in the process of trimming and curing with just over half of one plant left to go. So far I am at 9 oz. I figure I'm going to finish at around 11 oz total from the clones. I must say the outside bud is less dense then the inside buds.
I'm hoping for a larger yield next year. Part of my problem has been my pot size. I'd like to plant in the ground but at the moment they need to be near the house for cover from the street. They can't be seen while in flower from a public location.
Part of the cure for that is we are having a fence moved which will give me the most of the back yard on one side with more areas available once a new garage/breezeway is built.
