the plant will yield this much if you are a seasoned grower with a lot of patience. Usually in per m/2 is like close to a 4x4 foot area. (i think atleast) im know math major... Total vegging time of a plant this type would require about 2 to 2.5 months vegging time. Of course this depends on vigor. also you would probably have to start in 2 gallon pot and transpot 5 then to 10 right before flower. you may want to consider a scrog or low stress training. and at least 600 watts (hps recommened) of light to flower. if you have a few grows under your belt you could probably achieve this. other wise i would buy the seeds. grow a batch and select a few mothers to clone from. succesfully clone a few then put the mothers into flower in the meantime. grow your clones and repeat the process.
