All I have ever needed was a small area for moms, a small area for cloning and a big bloom room. Why waste so much space on veg? You get your best veg performance by placing the plants into the room they will bloom in and using the same lights and space so they get acquainted with their room.
That said.. 10x10x8' more room for me would be filled with 4 1000w lights over an 8x8 table area. I would use 36 2 gallon smart pots with loose fill hydro media (rocks/wool/coco), 2 drip lines per pot. Drain to waste if cost is no option, probably around 70-200 gallons of tank space. CO2, 36,000 Btu of A/C (Dual 18,000 Mini Splits would be ideal), 1-2 Dehumidifiers. No Glass on the reflectors. 4 Fans hung high, blowing down. Run the temps around 78F, CO2 around 1200ppm.
A small closet I can do all the veg for that, with a 8 bulb 4ft floro for moms, in soil. and a 4 bulb 2ft light for rockwool clones. Heck, if you have one strain you wouldn't even need that much space, just the 2ft 4 bulb would work, keeping a few clones for moms and cloning when your about 2-3 weeks from harvest and killing moms to use the same bubs for clone/veg. If you go that route, buy yourself a hydro tray and run your moms hydro under 24 hour light so the growth rate works out.
With a setup like that, 6-8lbs every 2-2.5months is possible. Why waste huge space on veg again?
