I think it's time. I currently have a 5.6 ×7 ft vert room built into an an 11 × 11 foot room, ruining 2 bare 1k bulbs.
I am implementing a ppk system after this run in flower as I have in veg so I figure I should knock down a wall while I'm at it.
My idea thus far is to build a 7×11 Flower room, leaving 4×11 lung room. Partially due to slanted roof. It goes from 11 ft to 8.
I have learned a lot since I first started about a year ago and want to tackle a few of the issues I have run into since.
Humidity control I see playing a massive role in plant health and speed of growth. I built my flower room with a 12" exhaust on a thermostat with passive intakes into my flower room. So I move a lot of air to keep temps in check, in so doing I have very low ambient humidity so I believe I want to run a sealed space.
I have a 60 amp panel to run veg and flower, I fix on growing trees to stay within my 15 plant limit.
I guess I just need a lot of insight.
I sealed off my veg rooms intake and exhaust to bring humidity up and have implemented co2 on a timer til I can afford a controller. I figure I should run co2 in flower also if I'm going to be sealed.

Sorry for the long winded post, just wanted some back story or whatever.
I want to run horizontal scrog like D9 or similar.
I figure with 11 ft in length I could do a 5×5 scrog under a de 1000 on both sides and have an isle down the middle but am wondering if a 3rd light in the middle would be wastefull?
I fix on getting some of the ac/ de hoods. I have a few 6" in lines fans an 8 and a 12. I am Hoping I can run the 8 through the hoods directly outside exhaust and intake but idk if that is enough?
I've got an 8k but window a.c., I feel like with vented hoods this should cover cooling but again am not sure.
Honestly not positive on how to run my lung without any exhaust leaving my flower room?
I figure that I should run my co2 bottle in flower instead of investing in a burner
I've got a 4 plant site system set up in veg. Not positive I can grow big enough girls in 9 weeks to fill that much floor space with only 4 but think I can come close and am open to adding to more sites if it becomes apparent that I need to.
I have yet to purchace de ballasts or the hoods but will start getting it together once I got a more solid plan nailed down.
You guys have been bad ass, all these threads inspire the hell out of me. Thanks in advance for any insight that you guys can off. Again sorry for the long winded sit, just trying to give an idea of what I'm trying to do. Hopefully I presented it a little less erratic than it is in my mind

the 8k wont cut it with 4 DE's not even air cooled. i ran a 8k with 4 SE 1000's air cooled and it barely kept up. id probably go with 14k minimum 18k on the safe side.

the 8' fan on the 4 lights should be fine if its 700cfm+

if you are going to seal the room and use CO2 then what would be the purpose of venting to the lung room?

with the ppk & DE's you are probably looking at a 6 week max veg to fill those 5x5's


here are some old pictures of my room this is before it was sealed, all i did to seal it was run the carbon filter as a scrubber, and the two ducts going into the plywood were intake and exhaust for the lights.

hope this is useful.

Heck yeah, you think I could pull off 4 de lights?
I was thinking 3 max but wasn't sure if the 3rd would be a waste.
If I understand correctly I can get a 5×5 footprint . With 2 that would take up 10 ft of my 11. I'm just tossing around the idea of like turning 3 down to 750 and side by siding the 11 ft. Just don't really know.
I'm not sure on the practicality of a lung room anymore. It has served me well with my vert set up but this will be new on my.
Something else just came to mind. I will now need a dehumidifier for late flower. Any idea on what size I'd need?

You don't think I'm over estimating this ppk set up with running a 4 site system ?

[Speed of green]

why not ditch the lung all together and 11x11 flower?


if you are going to keep 7x11 then yeah 2 DE max & your 8k will be fine. no need for the third light.

with the four plant system will you run two ppk sites per DE?


sorry im a bit confused.

lets nail down the light and plant setup & then calculate the dehumidifier.

[Earlmarne]

I'm thinking 2 lights 2 plants under each

[Speed of green]

okay, for some reason i thought you were knocking down the wall and going 11x11.

in a 7x11 space 2 DE's and 4 plants will work nice, having two plants per light will cut way down on the veg time.

i would look in the 70 pint range for the dehumidifier.

will you duct your lights directly outside?

That's what I've been thinking.
Filter on the intake side . 90 on the exhaust side

[Earlmarne]

I want to run 4 lights bad. I just think it'll bring my op into a lot more work and push me to the edge on cooling and power All together, not to mention room. I think the 8 ft side of my shop would screw me too with de lights.
Should be able to pull some good crops from 2 lights.
Been documenting this first ppk run due to being a novice gardener I don't want to screw anything up or miss something. I am really impressed so far. My gorrila bubbles are far from dialed. Mag deficient pretty fierce and up until a couple days ago my rh was around 20. Even so, in 3 day they have grown 6 inches taller.

[Speed of green]

you will be exhausting your a/c this way & you will not be able to use CO2 in the future if you ever wish to.

you can always play around with the ducting later, but if you were to intake and exhaust from the outside you will be more efficiently cooling your room.
