I love seeing old threads get resurrected! Seems the original question was "But i want YOUR opinion. What is the highest yielding cannabis plant?", which morphed into set up and other factors affecting yield.. So here's what I've experienced and learned over the last few years:

Yield is a function of plant size, regardless of the strain.. small plants, little bud. Big plants, lots of bud. You can do things to control this.. I personally like to grow in standard commercial nursery pots using soilless mix. Hands down the least hassle. In my set-up, I use 2' x 4' carts with a trellis assembly of the same dimension built in. I vary the height of the trellis depending on what strain I'm growing. What works here for me is: 2 x #5 or 1 x #7 containers in the cart.. the #7 will allow for one big assed plant, which I normally use for sativa dominant plants.. I always prune (generally FIM) and get them all to branch making multiple bud sites and fill up the trellis. This typically results in somewhere around 12 oz dry per cart.. sometime more, sometimes less.. I also have 6.5' of vertical head room to the lights.. Top yield for me was +15oz off of a single plant in a #7. This was a Barney's G13 Haze that had several buds over 16" long.. so much for the description of a medium height plant..

Basically it's all dependent on having good space, light, ventilation, proper temp/humidity, and ultimately knowing what you're doing. Skilled growers can usually get a good yield out of most good genetics..

Regarding top yielder's - I think it's hybrids.. best of both worlds, sativa height and indica weight.
