Hello. So I run these tables for a group I run for no other reason than educational purposes. Each table is a 4-ft square table although there's only about 1 M of actual tablespace beyond the lip. So they are about 40 in inside diameter. I use 4 in by two and a half inch rockwool cubes packed at 9 per square foot. They are flowered immediately after rooting for about 21 days in inch and a half rooting cubes the AO Flats of 98 cubes.
For a mother area I use a 400 w LED that has one or two large plants in which I take 100 to 150 clones every 18 days. The flowering tables have an average of 450 watts of light each so about 1800 W flowering area. Each table I average between two and a quarter and three and a quarter pounds which is about 1,000 G to 1400g per square meter from 450w .
So around 10 lb to 13 lb every 70 dsys with no down time. I also do not defoliate clip the tops use CO2 or anything like that I simply flower the clones and leave them alone until I harvest them although I do drop a mesh on top of them around the 21st day to stop them from falling over as they usually get quite large. Not every clone produces but the one next to it will simply produce more. These tables are Bruce Banner. They are on the Lower Side around 2 and 1/4 to 2 1/2 lb per table.
