Oh, fun! Ok, here's my perfect "Somebody just handed me a sh!t-ton of cash" setup:

BLOOM ROOM:
10' x 10' room with four 600 watt HPS lights in cool-tube fixtures
AC unit and electric baseboard heat to keep temps the proper range
Ebb & Flow hydro system with individual containers connected to a single 'bus line' running along three walls of the room with quick release connections to allow a plant to quickly be added or removed.
CO2 system and room exhaust with carbon scrubber and ion generator.

VEG ROOM:
Also 10'x10', separated from the bloom room by a sliding/pocket door. Similar AC and heat as Bloom room.

Two Ebb & Flow trays under a 5 bulb T-5 fixtures for plants headed into the bloom chamber, Bubble cloner under fluorescent fixture, one floor to ceiling cabinet split between equipment/supply storage and a library of mother plants under CFL. Small Breeding cabinet with it's own vent system for male plants. Drying cabinet, utility sink, small workstation table.

Other goodies: Inline PH/PPM meters for both Veg and Bloom. Good USB microscope connected to a cheap laptop. Sulfur burners to avoid pests. Cannalyse (sp?) testing kits. Seed collection for a number of good true-breeding strains.

Ahhhhh.... Gonna have good dreams tonight :-)
