Grow room design

Here is an 18ft x 36 ft room design with a seedling and veg space of 6ft x 18ft and a blooming area of 12ft x 18 ft. Where the "B" door is there is a swinging shelf with a door hidden behind it. The shelf in room "D" has four tiers with two flouro 40 watts x2 bulbs on each of the four shelves. The very bottom shelf houses a 400 watt MH horizontal light for vegging. There is a 6ft x 6ft space under the light that is 4ft high. Also in the veg area are the main breakers, timers, pots, soil, fert supplies. All the walls are covered with Mylar. An oven hood with fan sits at the top of the shelving unit and draws hot rising air out. Passive vents are used in the room for intake. A digitally controlled oscillating fan/heater is also in the room plugged into a computer UPS system in case of power failure. In the budding room there is a single roof mounted fan with passive vents cut near the roof and near the base of the floor. Installed here are 6 x 1000watt HPS lights all on individual circuits and timers. The lights are placed in a circle pattern. One in the middle and 5 around it. They come on in different sequences and positions. Never more than 3 lights running at one time.
