If you had the chance to set up a 2000 sq ft room how would you do it. This is assuming unlimited funding, unlimited plant count and electricity usage not being a stealth concern.
I would use HID lights over NFT channels. Takes a couple of hours to draw up floor plans and an equipment list so best of luck with that. Prepare to receive a trailer full of equipment. To be perfectly honest with you bro, if money and steath were of no concern I'd just hire a contractor to do all the work.
