Ok everyone I didn't know exactly were to put this thread and since I'm building a grow room, I though I put it in the Indoor Growing thread.

When you look at the pictures, I've used red gloves to show you how big the room is going to be. From the wall to the gloves is 6ft and from glove to glove its 12ft. Check out my other grow journals that I'm calling projects. 4 possibly 6 different strains. The bagseeds are unknown and they are from two different bags.

So here is the list:
6x12x9ft room (I'll have a drawing spec put up whenever I get a chance)
-Mylar and also black/white sheeting - bought
-(2) 1000w HPS (air-cooled) -bought
-6" can-fan for air-cooling the 1000w HPS - bought
-(2) 12' vortex fans (one for exhaust and one for intake) - bought
- Carbon Filter. I'll be getting the Can125 - bought
Alternative Garden Supply - Hydroponics & Indoor Gardening Super Store
- 50 gallon drum for water, with hose and sprayer. Heating element and pump. - bought
- Climate Controller - bought
- AC unit - still need
- Humidifier - still need
- Lumber - still need

Welcome to the forum, Blackhawk. 2-12' fans? thats big man. Just a suggestion. It looks like you have a lot of room available. If I had that much room I'd go 8' wide. That would allow you two feet around all sides of 4' by 4' tables. By the time you get all the ventilation etc. set up you will see what I mean. Won't be much difference in lumber, just less waste. It will save your back. VV

Maybe I posted my dimensions wrong. I'll be changing it to 8' deep instead of 6' and 12' wide. Width and length in my mind is different on the way you look at it. Anyways...so from the wall it'll be 8' and then 12' in width. Either way it's the same square footage.

As far as the 12" fans goes, I've read that you want your fan to move the air in the grown room 3-5 times in one minute. So my fan true CFM rating with the carbon filter is around 892CFM or something in that range. The cubic feet of my room, widthxlengthxheight (8x12x9=864). Times that by 3-5:

3=2592 CFM
4=3456 CFM
5=4320 CFM

So with the addition of an oscillating fan and force induced 12" fan, I think it'll compensate. I don't know I maybe wrong, I'm not an architect or engineer when it comes to building grow rooms. But I'll definitely take your idea and move from 6' to 8'. I want to have room to move around in the grow room and I believe I have enough light power for the plants.

I'm up for any suggestions, like I said before I'm still in the process of drawing the plans on paper and will soon post it up for any suggestions or improvements before I buy the lumber.

Nice stuff man. I like to see people that go ALLLL OUUUTT!!
I have the same hoods by the way, i fuckin love em!! Good luck... looking forward to more pics!

I was just jerkin your chain over the typo- 12' fans. Again welcome. VV

Ahh it is good to see someone who has some space bought the right stuff to get it going and should be able to do a full out nice grow.All you need now is a co2 injection to double your yield.Keep the project comin.

Yeah, Man, things get all discombobulated when spread around the net.

The general rule for ventilating a growroom is to move the cubic footage every 5 minutes. IOW for a 1000 cf room, use a 200 cfm exhaust. Now for more light heat, and curves in ducting, you will use more CFM, but that is the original rule.

2 -12" might be a little too much for a basement. which it looks like you will be putting it down there. with two fans you prolly wont need an A/C. it should stay cool down there even with those to lights. math is one thing to use when determining what you will need. but many times, due to curves and length of duct, after you set everything up you might have over done it or need to go back to the store. i bet you will find that one fan will be suffecient. i had the pleasure of visiting a friends grow in arcata cali and he had 6 1000w with oct hoods with 1 fan. it was 74 degrees at noon! and this was not in his basement. i have mine set up with 1 -1000w in an 5x5 area with a 6" inline @ 265 cfm i think. real small, for an oct hood like i have. also connected is a 3x5 veg with a 250w open hood. el cheapo 8" blower for intake (50$) air fresh from outside. 78.9 degrees at peak in my flower room. i try not to use A/C or heaters if i dont have to. and also if you do implement co2, it will be wasted as it gets sucked out from your beafy fans. air cooled hoods in line hooked up to the exaust will suck most of the heat out. and if you keep your ballast out of the grow room that will lower the temps as well. like i said, the basement is a lot cooler then anywhere else. and dark! for co2 theres mushroom kits for 150$. it is grat stuff. the mushroom last about 2 months and is cheap for a replacement. hope this helps. keep postin pics as you build your room. there can never be enough. oh yeah! my buddy said that if you put a filter on your intake, it can lower humidity up to 30%. i built mine out of the box my ballast came in and a A/C filter from home dePOT. 15$ total cost.
