It was 9 plants in 12 litre buckets (orange B&Q ones)
In soil (plagron batmix) layered with clay hydro pebbles, about 50/50 mix
I bent them over when they were young to get the lower branches as tall as the main stem, each plant had around 7 main branches.
I did clear away a lot of the lower foliage so the air could circulate under them.
i got about 17 oz from that, it woulda been more but i timed it badly and had to chop it early coz i was going on holiday. i took it at 7 weeks 5 days. I reckon if had let them go for 10 weeks it would of been nearer 25oz. You live and learn lol
if ther is anything else you wanna know, just ask mate. I'm still a relative noob though
