well since I'm building this system for someone else I'd like to install something that works on the first go without too much tinkering. a light rail is possible I suppose, but nothing fancier than that.
how many lights would you suggest with a rail?

Just a generalized comment here, but if it were my area I would decrease the area dedicated to mothers and clones, adding it to the veg area. Also, one 600W MH would be ample for even that large an area as clones don't need much light, and in my personal preference, I like to keep my mothers in less light to induce stretching. Longer internode distance makes it easier to take cuttings. I guess it depends on the growers preference, how long they like to veg their plants and whatnot.

that's a good point actually. no need for 1200W for clones and moms I would think.... but vegging might require a little more space.
So what about a grow system to handle that size of an area? I was thinking the giant Ebb and flow like these
I think that would be nice because we could make the buckets detachable so that when a plant is ready to move from vegging to flowering we can literally just detach the hose and carry it into the flowering room..... but then we have to deal with ENORMOUS reservoirs to handle this many plants. I was thinking at least 2-3 separate systems in the flower room to create a perpetual harvest every 2-3 weeks or so... Thoughts? I think aero would be very cool, but I think it'll get really messy carrying 20 plants with dripping roots hanging down all the way across the room into a new system...

Personally, I wouldn't go with a light rail but that's just me. No sense making things more complicated than it's already going to be. Maybe in the veg room at the most but not for the whole grow.
On the other hand, the Ebb n Flow is a much better idea than the aero. Easier to maintain and like you said, transport from veg to flowering. I would have suggested it earlier but I thought you might know something about aero that I didn't.
When are you supposed to start this project anyway?

Nah I agree, light rails are kinda pointless IMO, I'm glad you said that 
do you know much about ebb and flow systems? I don't entirely understand how you control the pump to prevent the buckets from overflowing. Also, do you use two pumps or just get a pump to go in reverse?

Check out some of the larger grows in ICMag for ideas. I've seen plenty of grows mirroring your dimensions and wattage before.
Check through this thread too, you might get some good ideas?
I've never built anything that large so I'm not going to be of much assistance, but it really seems like you have the right ideas coming.

Here is the tutorial I loved the most. This guy has gotten AMAZING results and has been doing it for a long time with proven reliability and whatever scale you use the system.
Recurculating DWC Buckets
Tons of people have mocked that system and even noobs had good results.

I don't know anything about E&F systems. Magash would be the one to ask about that. From what I understand, that system you posted a pic of is the exact same one he uses.

On E&Fs the pump is on a timer, set to turn on for however long it takes to flood to the desired level, then the water drains. Personal preference and other growing parameters dictate how many times a day to flood. It will depend on the media used, size of the plants, the strain, etc. Basically, as often as the roots can dry out you can rehydrate them, generally 3-6 times a day, or more if your media dries out fast enough. I would say E&F is mandatory for a grow of this scale, that way you can mix nutes in 100 gallon increments. You will need bubblers in your nute rez's to keep them from growing algea and other bacteria and mess.

I was thinking about just having a 3/4" fill hose and a 2" or 1.5" drain hose right at the top of the res so that it can always drain back to the res faster than it's being filled. that way I could just turn on the pump for 15 minutes and it'll just fill to the top and keep replenishing the water until the 15 minutes is up... does that make sense?

also, what size ventilation do you all think would be best for this? I'm thinking this bitch right here with 12" ducting on the centerline, but 6" ducting from light to light connecting into the 12". booster fans? or do you think 2050cfm will be sufficient? lol

Yeah I would say that's what you should do. 12" is pretty massive. I can't wait to see this through. Please tell me you will document and take pics of the operation...

Found it!!! If you want to know how that particular Ebb & Flow system operates you can find the instructional .pdf on this site: http://www.hydroponics.net They are the ones who actually make the system. Magash posted this link a while back and made me seriously consider getting one myself. Think I'll go with a GH PowerGrower eventually though.
The controller in the system has a float valve that fills the buckets to a predetermined level then shuts off. When the timer shuts off the pump reverses the flow back into the reservoir (from what I understand from reading it). Check it out.
That 12" fan should be just about perfect for your ventilation needs.

Ok that system looks great but I have a couple questions;
not so sure if I like the containers only being 2 gallons for roots.... I would really
like 3.5 at the least, this guy specifically said he wanted to grow trees....
Also the 48 pot system has a great price for how large it is, but how Is a 55 gal reservoir supposed to fill (48x2)=96 gallons of root space?
I'm afraid it wouldn't be economical to buy 4 of the 36 or 24 pot systems either....

No problem Harry. That's why I said I plan on opting for the GH PowerGrower. It has a 3-gallon growing chamber and 5.7-gallon reservoir. Which might not seem like much difference but in reality it's 33% more growing space. The only problem with it for your application would be the size of the controller reservoir, which is much smaller than 55 gallons.
When I do eventually try hydro I want to grow trees also. Which is why I'll try the PowerGrower. Unfortunately in your case it seems like you would need a separate PowerGrower system for EACH 1K light. I would like to expand on this system myself and make a bigger controller res but until I have one in front of me, and know the details of how it works, I'm kinda stumped.

Wow, are those 5 gals? Ive never seen that. nice big plants production equipment for sure.
As for ventilation it depends n the size of your room and intervals it's set for..
So you don't want to over or under do it.
Here's a link to a CFM calculator that's helped me for sure. clicky click
Hope this helps and I'll be watching this wet dream:)

Lol dude I'm fully aware of how to calculate cfm thank you. This is hardly my first grow room I've designed, it's just the first of this size.
Also they're not 5 gallons, hence why I was talking about them being too small like 3 posts ago.
Greenthumb, would you explain to me how the size of the controller res affects the system?

I think Smoke was referring to the Powergrower bucket res which is 5.7 gal.
I'm not too sure how the the controller res affects the system; but I assume if the Res was bigger then you could run more buckets in a Powergrower system. This is why I NEED one. If I had one in front of me then I would just build a BIGGer Powergrower system (with more than 8 buckets).

wow. sorry man. I wasn't talking down to you I was just trying to help.
Maybe it was the.. Quote:

as since you didn't give your dimensions I didn't know what you would need.
Sorry, Like I said i wasn't trying to speak down to you just putting in my two cents.
