i dont do it now but its my intention to do a 2 week perpetual grow next, usin sog and only soil, 12 mothers, 100 flowering at one time, 4 different 2 weekly stages of flower, so every two weeks 25 just vegged plants go into flower and 25 come out, hopefully achieving 200 g every 2 weeks, im still tweaking the idea here and there so when my current grow is done il be ready.
