Hey fine people!! Okay, so i'm gettin ready to build a rather large grow room, 12wx25-30Lx10-12h, with 8-12 1000wt lights, sealed room environment w/ Co2.

I'd like any and all input! I've got the rough dimensions, and done calculations as far as lumens per sq. ft, semi-decided what products and methods are going to be used, but I would like some input, especially from people who've done bigger ops before. I've subtracted 4ft off the width and 8ft off the lenght to allow for aisles, room to move, etc. when factoring lumens per sq. ft. If I go with 12 lights, i've got 10,000 lumens/ sq. ft. of utilized space. Tell me if i'm missin something, factored something wrong, etc. Please!!

Okay, so like I said the room is going to be sealed; the only exhaust is going to be for the air cooled lights. Fresh air pulled straight through the hoods from outside the room and vented back outside. The room will have one, or two if necessary, portable a/c units, one dehumidifier, one sulfur burner ( for powdery mildew, etc. ), Hydrogen water cooled Co2 generator. Big Can fan and filter running inside the room for odor control. Hmmmm...lets see. Lights might be on light rails if I can still swing the cost. Growing medium will be a personally blended soil mix, with lots ( 30-50 % ) of perlite, and other goodies. Watering will be done by hand initially, might automate and/or switch mediums in the future. We'll see after a crop or two.


Having 100amp service panel brought in; lights will be on 2 50amp 8-junction timer boxes, or maybe 1 50 amp and 1 30amp 4-junction box, both @240vlt. A/C will also be on 240vlt, the rest of the equipment will be ran off 120vlt 20amp circuit already in place. Lights will also have a Hi-temp kill switch controller in place.


A/C , dehumidifier, sulfur pot will be controlled by a Sentinel EVC-1 Environ. Controller. Hood exhaust will be controlled by a seperate temp controller, probably a TMP-DNe Day/Night controller.


Co2 will be controlled by a CAP PPM-3 unit.

Probably going with one of the larger reflectors, SunSys. Magnum XXXL, Yeild master supreme, Sun. Supply Great white, or Hydrofarm Mondo.

Couple 2 or 3 16" wall mounted oscillating fans for air movement.


Probably going to use Advanced Nutrients products for nutes.


I've got lots of things figured, and i'm not going into alot of the finer details here yet, but where I'm uncertain is for instance, Canfan and filter inside the room. Should I run it only during the light cycle, or at night as well. Should it be continuous, or intermittant, and should I hook up a speed controller to the fan, or always let it run at max cfm's. This will be my primary source of odor control, so I want to be certain. I will put a smaller charcoal filter on the hood exhaust line if it seems to be pulling any odor with the heat, but the reflectors will be sealed, so I don't know yet if that will be an issue.

Room will be framed normally, pressboard outer, 2x4 walls, sheetrock inner, also framed up off the concrete floor, possibly with some cheap white linoleum as flooring. Haven't decided yet on either flat white paint or Panda paper for the walls.


Will be growing 30 plants cooperatively with my good friend, also a medical MJ user, so were covered legally. They will be very big plants :weed: to compensate for the relatively low number.

Okay, so am I missin something? Bad calculations? Anyone ever done this size op before? Or has anyone used any of the products, equipment , etc. that I've mentioned? Anyone done a sealed room before?


Any and all advice would be welcome and much appreciated!!!!!! ++++++rep


Thanks in advance!!!!!!:peace:

Hmmm...50 views but no replies. I know all you people are just as high as me, but I figured someone would say somethin. I know that's kinda how threads work, lots of views, not that many replies, but I kinda need replies on this one. I'm askin!!! I didn't start this thread to boast of a big op, or fancy shit, or just make some shit up like some people do ( WTF? ). You can see the treads in my sig., and know i'm not clownin. It's happening in a matter of weeks, and I'm tryin to finalize what I'm gonna need so that we can start aquiring what's needed.

Sooo, little help would be cool and very welcome!!

For instance, on a room that size, in anyone's experience, will venting heat from the hoods ( 8-12 1000wt lights ) , along with one portable ( 12-14,000 btu/hr. ) A/C unit be enough to deal with the heat? In a sealed room?

Or say, will a 10" inline fan, appr. 780 cfm, be enough power/suction, to pull through that many hoods, or do I need to put a fan on the air intake side of the ducting, before the hoods, to assist in moving the air through? And if so, do I use the same size fan with same cfm? Should I go 12" ?

Can I hook three ( I'm thinkin 3 rows of lights ) 6" ducts up to one 10" or 12" fan without some weird air shit happening or is that fine?

See, I need a little input here. Help a brother out!!!


Once I get going, I will be posting pics of complete setup through first harvest, and then who knows, my fingers will probably be toooo sticky to take any more pics, but we'll see.

:peace:

Am on the same boat i am subcribed to your threat i am also curiouse to see how much A/C you need for that space wish you luck and i wish i could help!

First off, get Max Fans instead of the traditional Can Fans. They move alot more air, and do so with less electricity. Second, with that many lights, you should check into iceboxes instead of trying to move all that hot air. You'll need a remote spot outside the growing area to put the chiller for that though. Based on your requirements, you need 1/4 HP for each 1000W light. So if it's 8, you'll need at minimum a 2HP chiller. That will not be cheap, but probably not too far off in cost if your plan is to use 2 portable ACs anyway. You'll also need one hell of a water pump, and at least a 60 gallon resevoir for the chiller. The main benefit from doing things this way is that you won't have to run ducting in/out of the room and have massive amounts of inline fans trying desperately to keep the room cool.

MC! Mic check 1,2....1,2! What up! Max Fans huh. I was lookin at 'em, and I just might take your advice!! Iceboxes are pretty spendy aren't they? And yeah, chillers definately are as well. Do they make 3 HP? Hmmmm...I'll start crunchin #'s and see what's up.

Thanks for the info and advice!!!

You'd be better off growing vertical with a closed system and put the money you'd save on hoods into a 5 ton a/c unit.
A single 12kbtu a/c isn't going to cut it.

Grow like this with a couple pounds per plant rotating maybe 15 into flower at a time:

Oregonmeds ( I'm from Portland!!! Oregon kicks ass!!! ) you just gotta go and fuck me all up huh? Dammit!!!! And here I thought I had it all worked out!!! Hahaha

Nah, I've thought about goin vert. Saw alot of examples of it on Urban Grower, and it definately kicks ass and is a proven method. Now I have to rethink my whole shit, thank's alot bro!!! 5 ton A/C huh? Alright, I'll seriously look into this method, and crunch some numbers as well.

Thank's to you as well for the info!!!

This is what I'm talkin about!! Hook a brother up!!! :peace:

Honestly bro, if you're going to give iceboxes a shot, I'd recommend you get two chillers not one if you're going to have 8 lights. You may still be able to use a shared resevoir, but trying to pump that much cold water over the distances the lights will be spread apart may be too challenging even for a multi HP chiller. If you got 2, 2HP chillers, I guarantee you'd be very successful. Try to keep your runs with the lines as short as you can, but also try to maximize the use of your lights. Good luck.

Yo riz if you are only 12 feet wide and 25 long. Why not 2 or 3 600 or 1000's on 3 separate light rails. If you have 3 lights on each rail you could almost make 3 seperate grow hallways. Might be convienent if you ever find yourself in a perpetual harvest.. which it sounds like you could do with the medical card. Might also be easier to cool smaller spaces than 1 large one. Do the logistics, it sounds like you know what you want

Have you read through MBlaze's journal on growing monster plants indoors. Might be something you look at before making your final decision.

The portable ac units will not work in a sealed room it will suck out all your co2 ..You will need a good chunk of money to get started $20,000 plus to get it rite ..Check out my grow its in my sig I am running a sealed room CO2 and 5,8000 Watts..Also there is some really good vids of similar rooms on www.urbangrower.com :peace:

Yeah JMO!!! You hooked it up proper bro!! I've seen all the Urban Grower episodes, and that's what I'm kinda shootin for. Just don't have the initial $ for a big A/C unit, and you're right on the portables suckin out Co2, but only if they have just one hose. If you use the two hose models, and pull your intake air from outside the room, you don't have that problem. Kinda workin in reverse, pullin air from somewhere else, chillin it, then putting it into the room, as opposed to takin the hot air from the room and chillin it. Guess it's not really a sealed room then, but at least the Co2 is stayin. Oh well, there will be numerous upgrades along the way, first off a proper A/C unit for sure, But I gotta work with what i've got for starters.

Thanks for postin bro!!

OM!! Yeah man, I'll hit you up soon! I've been really busy lately and just findin time to respond to peoples posts on my threads is hard enough!!

Small world indeed!! Every time I'm back in P-town, I feel like I'm back home. Still have lots of friends and family there, and I always love comin back. As I'm crossin the bridge into Oregon I just start smilin:-D. I'm missin the Sandy river during the summertime too. The rivers up here are fuckin COLD!!! Damn, makin me jealous and homesick, thank's alot!!!!! I'm clownin bro!!

Yeah, I'll hit you up, and next time I'm down there, we can hook up and blaze a fatty!!:peace:

Just a quick post to say that construction on the room has started, and equipment is on the way!!

Room's gonna end up bein about 13.5' wide by 28' long, and I'm thinkin 10' lid instead of twelve. The square footage increased a little, so I want to decrease the cubic feet a little to compensate, make it easier for the Co2 gen to fill the space.

Couple of pics of the framin, nothin special, I'm just excited that it's startin, feel me?

Hey Boulder!! What's shakin bro? Thank's man! The area, hmmm........well it is in the spaces betwixt the air itself. hahaha It exists in a void, neither here nor there.

Quick update. Finally got the power dialed in. New service panel with 50 & 30 amp breakers @ 220, two more 20 amp breakers @ 110. Range and dryer outlets installed. Construction is more than half done. Equipment and supplies have been ordered. Clones are being taken this week. I'm fuckin beat.:peace::blsmoke:
