The new setup is planned, and aside from a CO2 Monitor and a CO2 regulator, I have everything ready. This setup will utilize 4 rooms. There will be a Mother room, 3 flowering rooms, and a clone closet. The clone closet will be running on T5 HO flourescents and a ton of CFLs in a few long fixtures I made. The room is about 5'x8'. It has a 150cfm ceiling vent into a duct that travels into the backyard, the intake is passive and the door will be left open into the veg room since they will keep the same light schedule (18/6). There should be room for about 200 clones. As soon as they are sufficiently rooted, they will go into a flower room where they will recieve 1-3 weeks veg time before being flowered.

The veg room is about 12'x10' and has a small A/C unit drawing air from outside; this is the intake (will be supplemented with fresh air if needed). This room will not have CO2. Currently, the plan is to have about 12 mothers that will be running off some 400 and 600 watt HPS lights. Eventually, I would like to setup 8 recirculating DWC hydroponic 5 gallon buckets in this room, veg them for 2 months, and then bud them in one of the flowering rooms. But thats the future. There will be a dehumidifier as well.

Now the 3 flowering rooms. 2 of the rooms are next to eachother, the other is in a different location. Because its not close to the other rooms, the 3rd flowering room will not get any CO2 or A/C. This will be my control room as Id like to see how the yield differs without these environmental controllers (I have never used CO2). It will be cooled with a 6" Fantech 300cfm inline fan and exhaust with something a little slower. There will be 2 1000watt lights in there, both aircooled.

The other 2 flowering rooms are the pride and joy. There is a closet in one of them, with a large window. A large A/C has been purchased and will be flooding the closet with the cold air. The cold air will then be drawn from here for both rooms. The cold air is brought into both rooms via a 10" 750cfm inline fan and a slower 8" inline fan (dont know what speed to run em at yet), and exhausted by 2 10" 750 cfm inline fans. The exhaust fans will be pulling air-conditioned air through the aircooled hoods. Ive seen this done and you could have your hand 8" below the glass and it was fine. One room will have 2 1000 watt HPS, the other will have another 2 1000watt HPS. Depending on what the energy bill is like, I might get another 2 1000 HPS or I might get rid of one of the flowering rooms and put 4 in one.

The 2 side by side rooms, will be supplemented by CO2. A CO2 controller will control the fans, the A/C, the dehumudifier, the lights, and the CO2 regulator. Target ppm is around 1800-2000. Not entirely sure of the schedule, but probably 2 hours on, vent for 15 minutes, 2 hours on, vent for 15 minutes, etc. The hoods will be sealed so they can continue to be aircooled without pulling CO2 from the room. There will be oscillating fans inside to distribute air and CO2. It will be a little complicated to setup the venting so that we can keep the air cooled hoods on, but keep the room sealed otherwise. The most complicated part will be distributing the CO2, as Id like to use one tank and one regulator to do this. What I havent figured out, is how I am going to control everything correctly because I dont want CO2 at night and there will be periods of 1-3 weeks where both rooms share a different light schedule (one in veg, one in flower). Probably I will just cutoff CO2 for 4 hours to the flower room in veg when the flowering room is in darkness and is just using fresh air.

I am going to try to have a very very very controlled environment with these last 2 rooms, as they will be the pride and joy. The property is off a private road, there are no direct neighbors. I feel safe about that aspect.

In HID lighting, thats going to be about 8000 watts. A crapload. The 2 connected rooms must keep the same general lighting schedule since they are sharing CO2. I am a little worried about the power consumption so I am going to get one of those things Tranoble has that redistributes power around the house and is supposed to save 25%. The rooms will ALL be rewired to 240 volt. I want to be able to leave my house for a week and not worry about it burning down and I want multiple lights on the same circuit for ease.

So do you guys think that I should run 2 flowering rooms, one with 2000 watts and one with 4000 watts? Or just run the 3 flowering rooms with 2000 watts each? 1 am leaning towards just the 2 flowering rooms and then possibly using the mother room to veg clones as well. Essentially I want to maximize the number of times I can harvest in a year. Having it 1 month apart would just be beautiful.

Well, I think that is it for the new setup. By the end of September, the first wave of clones should be finishing up veg (figuring about 50 clones).
