What's your Perfect growroom?

If you could make a perfect grow room what would you make?

Here's a quick sample I whipped up in my floor plan software. I haven't yet thought what lights, etc, I want in the room, but this room would be ideal.

For me, a nice 12x12 room with mayb2 5x5 tents in it. Veg and flower in same room with a 1k watt light for each tent. Maybe a nice RDWC system in both tents will make the operation a little more self contained. Thatd be all I need!!
