With 12 plants under a 1000 watt and a 600 watt HPS I expect to get 3-5 ounces a plant to be a successful grow. I have grown many different strains, and this holds true with most situations. Sometimes, when trying new strains from seed, you can have a crappy yield on a plant or two. Most times for me, I am using my proven mothers to make really nice babies, that like to yield well, and smoke well. Hope that answers your question a little more. I grow in soil, and top my plants with a combo of some LST and supercropping. Basically, a pound a light is a good goal for most folks.
I also use strains that flower between 8-10 weeks, so they usually finish at 9 weeks or so. Give or take a little. I have grown Ice, White Widow, Crystal, Blueberry Widow, and some others, but those have been my great ones.... Here is a pic of my Ice Anomaly, which will be one of my newest mother plants.
