Help!!! deciding on a 3600W - 4000W vertical stadium setup with lung room

Hey guys, this thread could go in the design and setup forum, but I thought I'd get the best help here in the vert section. I hope that's ok.

I have a long rectangular space 9' wide by 30' long. It will be a room inside of a larger building.

Because of the long narrow space, I plan to do a vert stadium.

I have two basic choices:

1. Split the space into 2 parts. 10' for a lung room, and the remaining 20' for the grow area. If I did it this way, I'd be looking at putting 4x 1000w HPS lights down the center.

or:

2. Split the space into 3 parts. So I'd have roughly 3 10'x10' rooms. I'd have the lung room in the middle, and a flower room on each side. I'd have 3x 600w HPS on a flip flop, so I'd have two 1800W flower rooms.

Option 1 - (1 flower room; 4 x 1000W) - advantages:
- I could veg plants for a little bit instead of having the lights permanently on 12/12 like I would in a flip-flop scenario.
- I could harvest all at once instead of having to do a harvest every month if I staggered the flip-flop rooms.
- May be easier to just having to deal with 1 flower room.

Option 1 - (1 flower room; 4 x 1000W)- disadvantages:
- the space might be a little tight considering it's only 9' wide. I would be hand watering with a pump and a watering wand. I would need space on the back of the stadium on each side to walk down to water. So I'd essentially be left with 7' of floor space if I left a foot on each side to walk down. This may be a little tight with 4 1000W.
- It would be harder to cool in the summer running 4000W all at once compared to 1800W on the flip flop.

Option 2 - (2 rooms; 3 x 600W flip flop - advantages:
- the stadium wouldn't have to be quite as wide using the 600s, so accessibility at the back of the stadiums would be easier
- would be easier to cool in the summer considering only 1800W would be running at once.
- would have the option of staggering the harvests which could be convenient.
- I would be using electric heat to keep warm in the winter. Considering 1800W would always be running, the heat from the ballasts and lights would reduce the need for electric heat, which would cut down a little on the electric usage.
-may be an advantage using a flip-flop with the new 'smart meters'?

Option 2 - (2 rooms; 3 x 600W flip flop - disadvantages:
- I could see vegging being an issue. The rooms would permanently be on 12/12, so the plants would need to be vegged in another area and ready to go directly into flower. May need more wattage and space for veg.

I'd really like to hear some of your opinions on what you think the best choice would be for my space.

ive been looking at seeds lately. something like nl5Xhaze might work for you. throw the clones under 12/12 right away. info says they can stretch to 1m like that. bit longer flower but no veg and allows flip flop rooms. also saw a thread where guy left clones in cloner for 3 weeks, had amazing roots..........

For that space I'd suggest doing two 8x8 2k stadiums on a flip for flower and another room for veg. I built a 12x20 room (fully insulated/sealed) and built my flip rooms (2x 8x8x7 2k stadiums) inside of that for a lung room on 3 sides of the rooms. My veg is a separate 10x10x7 with 1k horizontal for veg (600w for the first 7 days of HID veg), 216w t5 for cloning/starting seeds, and 400w MH for moms.

Each 2k stadium has a 10'' max fan (1020cfm) and 10x39'' phresh filter for exhaust, they run 24/7 and exhaust into the lung.
The rooms are staying at 78-80F during lights on, 72-74f lights off

The lung room is kept at 45% RH, 72-74F.

After this run I will add c02 (cap gen2e and ppm3 to maintain 1500ppm) and upgrade my dehumidifier to a santa fe max dry dual xt (150pint@AHAM)


Hope you got an extra 15-20k laying around to buy equipment and building materials ect...

Not cheap if you're trying to do it right......

it seems like you have broken down enough to answer your own question lol option 2 has more pros and less cons and personally that is what i would do

electric heat is extremely expensive and using one room to heat the other would be effecient and save $$$

having staggered harvests has a whole other list of advantages

cooling would definately be a pain in the summer with option 1

having a seperate veg area would be neccessary but even having one with option 1 would increase your bottom line also

lets say you got a 60 day flowering strain...

option 1- 30 days veg 60 day flower 90 days total= 4 crops a year if you hit a gpw that 16000g/yr

option 2- seperate veg 60 day strain two rooms month apart = 12 crops a year at gpw that 21600g/yr w less wattage and prob less headache

good luck
