expectations for yield with purple wreck at ideal conditions

a friend of mine is currently using humbolt master series nutrients, 2 600w high pressure sodium with 30% blue light, cool tube exhausted lights, all appliances hooked to environamental controller. first half of flowering at 1200ppm CO2, 70% humidity, 78 degrees with light on... second half of flower at 1200 ppm Co2 then stopped for the flush, 40-50% humidity, at 78 degrees when lights are on, and mini compact light are hung for second half of grow for more uv rays . grown in foxfarm soil base, not sure of the mixture, and in 5 gallon buckets.

the set up relatively ideal, with the exception of the water needing to get run through a reverse osmosis/any pruifying system, and id love to see a switch to advanced nutrients

looking to veg for 4 weeks and flower for 10. putting 16 ladies in 20 square foot room.

what should he expect as a yield pure plant?

will be his first non biesel, a low yielding strain, that doesn't have questionable genetics... im excited

2.5-3oz per plant, so 2.5-3lbs total

a butt load of pot...im happy for you man wish i could run such a setup...i would say at least 8ozs per plant times 16 plants...divided by 16ozs...8 lbs would be my estimate...but you would have to veg a lil longer than 4 weeks (otherwise its a waste of the 5 gallons space to me) ive gotten 8 oz plants off of 3 gallon pots...just have to top the plants continuously throughout vegging

isn't the rule of thumb about 1g maybe a little more per watt? i really don't see 8lbs from 1200 watts

And he tops the plant twice in veg, once every two weeks, and after a few weeks of flowering he strips most of the bottom and focuses mainly on the top 4 colas of each plant

He will harvest alot and it depends on what pheno he has. The purp pheno puts out the least so its all dependent on that plus your setup, but in my experience it should do over 1 gram per watt.
