I'll take a guess, but It's difficult to predict anything with autos. By their very nature they are unpredictable since they can't be cloned. I'd guess that if all goes well you will average 1.5 to 2 ounces per plant. You can have 100 seeds from the same feminized plant and get many different looking plants. The yield for their size will be good, but that's not saying that their size will be good. I've had autos yield 1/2 ounce and others yield 2-3 oz.
If you mess up the initial few weeks of growth somehow then your yield will be low. If you just plant them and let them be and give them good light then your yield will be decent.
Plant 16-20 in 3 gallon pots. Just plop the seed in the dirt. Don't try messing with them and up potting etc.. just plant them... Run some low wattage MH or fluoros for a week then hammer them with light. Don't LST or top or anything unless one is growing out of control and ruining the canopy.. You don't need to if you have a 1000w light. Give them nutes starting with 200 ppm in week 3 and work up 200 ppm each week until 800 ppm. In week ten or 11 harvest them..
These two seeds were from the same order. One on left = half ounce of nice quality buds.. one on right = 2.75 oz of nice quality buds. One on left in 2 gallon pot and grown indoors under 400w HPS. One on right was grown in 3 gallon pot under CFL, but set outside in the garden every day. Both were LST'd.
