I just recenly created a space in my garage for a bad ass big grow room. the size is 8w X 20L X 8h. that is about 160 sq. ft. and 1280 quipic feet. I would like to run 4 1000 watt lights over two 4X8 grow trays. a tottal of 64 plants 16 under each lite. I'll run a 12 inch inline fan for intake, and two 8 inch inline fans runing threw two lites. in other words 1 fan threw 2 hoods on each side linking back up off to the side to exhaust threw a carbin filter out threw the attic space i crated between the room and the roof. I'll have a 12,000 btu heater/ a/c. for heat and cool air as needed.I'm in the prosses of figureing out the c02 intake. i currently grow in a 7x9 area with great results but i dont use c02. have to learn. What an i missing will the lites cover. is the air intake out take suffiant. any help or feed back would be awsome. thanks
p.s. has anyone seen the new adjust-a-wing hoods they are awsome but expencive.

Room.jpgI am guessing you are going to attach a carbon filter to each hood and draw air from the room over the hoods and then out of the room in to the attic? From your description that is what it sounds like to me. You're going to waste a lot of co2 with that setup.

I have a setup thats very simlar to yours but my room is sealed.

My room is set up for 4 1000W lights but due to the energy companies new tiering system we are only running 2 of the lights.

I have 1 8" fan that is pulling air over my hoods and exhausting the air into the attic. My grow room is in a bedroom and I draw the cooling air in from the bedroom next door. I had someone tell me that the " fan would not be enough to cool 2 1000W lights but I can tell you it deifnitely is. I can hold my hand on the glass on both of my reflectors wihtout a problem we measured the reflector temps and they are about 95 degrees.

I have a 6" exhaust fan hooked to a carbon filter. The fan runs for 15 minutes every 3 hours during lights on. This seems to keep my humidity right at 50% during lights on. Unfortunately my humidity is now spiking to 65% during lights off now that I have 2 large plants late into flower. I am thinking the 6" isn't going to big enough and will be putting in a 10" Max fan in the near future. After the fan completes it's 15 minute cycle I am respraying co2 into the room.

To control teperature I have 14,000 BTU window A/C that can get my space down to 65 degrees on the hottest summer days with both 1000W lights running. I am hoping it will be enough to keep the room at 84 degrees with all 4 lights runnings but I don't know if it's going to be able to do that. I'll find out soon enough.

ok so my design is backwards i want to pull air threw a filter over the hood and exhaust out. not push it threw the hood threw the filter and then out.is this getting into neg. air pressure and pos. air pressure. is ther a standard when setting up a room. my other room i use a 6 inch inline fan pushing air threw the hood and out. this works for me because the fan is powerfull enuff to pull air in from out side the room. hay Bozzer do u got three plants under 2 1000 watt lites. thats damn intense. rite now igot 3 under one. and they are growing like mad cow shit. got some recon in ther rite now. workin on some bubba kusk, pineaplle express, and green crack mothers.

We're still waiting for the newest bill and a little nervious. The pic you see is my flower room. The flower room currently has everything mentioned in my previous post and I also have a veg room running an 8000 BTU Portable A/C, 400W MH and 175W MH. I'm probably going to just run 1 1000W MH in an 8" Magnum hood in the veg room pretty soon.

OP - Pulling air is the way to go. You want to pull the air over the lights not push it. If you're going to be running co2 in the room you need to pull air from another source and not pull the air directly from the room, over the lights, and out. If you do it that way youll have to run co2 constantly because your exhaust fan is going to suck all the co2 right out of the room.

I currently have 4 plants under the 2 1000W lights. The 2 bigger ones you see were a little over 4 weeks into flower when that picture was taken. The plant on the left is Purple Candy and the plant on the right is Pot Of Gold. The 2 smaller plants were about 1 week into flower when that picture was taken. The plant in front is Purple Candy and the one in back is Caramelicous.

I've got a few plants in my veg room that I'll be throwing into flower pretty soon. Our goal is to harvest 2-3 plants every 2-3 weeks instead of harvesting a ton of plants all at once. I've also changed the design of the room a few times. We started with DWC buckets and then started moving to the stink buddy aero system. I had a timer failing issue and it resulted in an entire crop failing, my cloner, vegger, and flower boxes were all run off the same timer and I lost everything. Close to 40 plants all in all. I had to start from scratch about 9 weeks ago and we are slowly rebuilding our strain collection. Needless to say I switched back to the DWC buckets and will be sticking to them. We may add a flood tray system to the other side of the room and put them under the additional 2 1000W lights the room is set up for but not sure yet.

Hi fellas. I'm in week 4 of flower, first grow. I've had many issues from heat, ventilation, humidity, and spidermites. I also sprayed my poor ladies with a bad mix and it burnt the hell out of them!!! Started with 10 and lost 1. All have recovered and are budding nicely! But I think I might have too much light on them. I'm in a 8x3 room that I built in my garage which I'm using 1000 watt hps. Some buds are browning but not all. I started rotating plants more and raised light yesterday so I will see when lights come on today. Light is vented and I have 2 oscillating fans in room, plus an ac unit which is keeping room at 76 degrees with 40% humidity. Should I go down to 600 watt if browning still occurs? I know the bud will start browning but should they already be doing that? Any help would be appreciated

A 1000w bulb is just right covering a 4x4 area. I know guys using a single 1000w with an adjust-a-wing and they are doing fine.

I run a sealed room with 2x1000w. I draw air from outside, through a cheap 3m filter, then into the hoods and back outside. No air in or out. Just AC and Co2. But I gotta tell you, my veg room is sealed too. I have no Co2 enrichement and it still has the same Co2ppm as the outside air. No room is really sealed unless you're at NASA.

In SoCal you will need a Dehumidifier.

i grow 16 plants in a4x4 grow tray, with a 1000 watt hps bulb lumnatec ballast and hydrofarm hood. my first round yeald was a little over a pound and a half. The new room will have a vapor barrier, half inch foam insulation board, then the white/black poly matrial from the grow shop, white facing in. I hear ya bozzer. i will follow pretty much the same setup. pull air from outside threw the hoods and out the other side. use a inline fan for intake and one with a carbon filter pulling threw the filter and out in the attic space. prob vent the hoods threw the attic aswell. the new room will be pretty well sealed. ill run 4 1000 over 2 4x8 trays. should be pretty abitious.any other thoughts or recomendations.

This is your opinion I presume. IMO it's a waste of 400 watts. User preference I guess.

I would go with a 600 watt in a 4 x 4 area and 1000 in a 5 x 5.

a 1k light doesnt cover a 5x5 very well, the outside plants wont get strong light. its ideal for a 4x4 area. also 600 arent great in a 4x4 but they are effecient and ideal and they get the job done. that said a 600 is common for a 4x4 area, a 1k is much better. 400 is only good for a 2x4 really.

suck the air from your attic thru ur lights and back out to the attict dont even let any room air go thru it like other dude said pump co2 and air conditioner into the room and yes ull need that dehumidifier when it comes flowering time so u can leav co2 on all the time they say it helps like 20-40% id say atleast by 30% in my exp.

You really only need 1 decent fan for a line of 2 hoods. I'm running 2 vortex 449cfm 6" fans for 4k watts and I can keep my hoods about 10" above my canopy with ease.

If you're sealing the room and want to run a carbon filter, just don't exhaust the carbon filter...let it blow right back into the room.

what i said isnt much of an opinion. a 600 is effecient, lower cost to run and will get the job done. 1000 watt will cover all the edges of a 4x4 area but not perfectly. even with a big kahuna hood i still dont get great penetration on the edges but a 600 is much less bright therefore the edges are even darker.

i understand that your all about the 600s cuz thats what you use but your suggesting that its better then a 1k for some reason.

You don't understand shit. Stop putting words in my mouth. I don't use 600's. I use 1000's in a 5 x 5. And IMO, they do the job great.

When and IF I use a 600, it works great in a 4 x 4 area.

What you said IS your opinion and what I said is MY opinion. Now get off my nuts and stop wasting your post count on me. I repeat what I said in my very first post here, it's all about USER PREFERENCE. :arrow:
