Update: actually got in and measured yesterday, pretty off in terms of dimensions. Attic is 100x10-12ft, widest at the ends. about 2ft of height at the wall, 7ft in the middle with approximately 70 inches of width in the center with at least 60" of vertical space. Current plan is to do a flowering chamber at either end of the attic reserving the central space for a workbench, drying and curing and veg room.

I'm insanely concerned with how to light and cool with such limited headroom. Was planning on going with a 10" inline exhaust, but am now thinking maybe I'm better off getting two separate exhaust fans, one for each flowering chamber? Thinking CMH or LED is the way to go for electrical efficiency as well as radiant heat without a giant gap, but looks like 5-6k just in leds. I may end up doing a combination of the two.

I'm going to have to have someone come wire up some outlets and whatever else, but there is already some power up there, the air handler is on one circuit and the overhead lighting I believe is on another.

Just got a 100a panel put in, should be okay considering it's a 1000sqft condo and my stove is gas.

Any better idea of layout setups? Not a ton of height to work with obviously, probably end up doing some type of scrog, my usual MO is hand watered hempy buckets, just fim once or twice and let em roll. This is only my 3rd or 4th grow so while I hope the entire space is eventually built out, I'm not planning on completing it all this go around.



From the other side


Where the wall kicks out a little bit at the end of the span, probably where I'll mount T5 and start seedlings and clones.

Maybe some sort of Low Stress Training, FIMing, or prune the plants good so they get bushy and not tall?

I would first worry about the environment, first. Attics get tealy hot. Ac, or atleast intake and exhaust will be necessary. Probably have to insulate well.Lst'd individual plants that can be moved around.

Baked or fried? I'll see myself out.

If you're NOT exclusive to the usage of LED lighting, have you given any thought to vertical, bare-bulb?

Was thinking more along the lines of lighting and how to separate a flower room and veg room when the ceilings come down quite steeply from the apex of the roof. seems awkward to light.

You are deffinately putting the cart befor the horse. Environment is EVERYTHING first things first, what's you electrical capacity. Start with your limiting factors. If you want to do a build, first figure out what you have for available electrical capacity. You are probably looking at 160 amps with the a.c., lighting dehumidifier and miscellaneous fans and such. Most houses only have 100 amp panel.

. I would hit up Dan's buds, he ran attic grows.

With height restrictions vert would be the easiest way to go. I would avoid any double ended lights. You will need at least 5k a.c. per light and possibly more depending on your weather.

Being that 50%of your floor space will be unusable , you could build it at 5-6 ft wide probably be 250 sq ft. Is a pretty good size grow.

I am not trying to be a dick. You have given very little pertinent info. Are you going sealed room with a.c. and co2? Are you running HPS, cmh, led? How many lights? No information on the temps and humidity. Electrical capacity?

The elephant in the room is do you have any experience? Most new growers think that it's about more lights, fancy hydro systems, snake oil additives. In reality The environment is the most important part of the grow.

Get us some pertinent info and we will all help get you lined out.

Insulated attic with window ventilation at either end. Don't really want to mess with co2 at this point so I'll be running it open. Right now ambient temps in summer are hovering around 77ish with 90+ degrees outdoors, so I'm less worried than I would be if it was uninsulated. Did just look at the power and only have an 80 amp main right now, just moving in so I'll see what I can do to get a 200 in there. Still defiantly need AC but hopefully maybe just a 10k. Also planning on running cmh so hopefully a little less heat to begin with. 4 or so smaller grows under my belt but I run blumats/coco/KISS right now with decent results.

Get the power updated I have never seen an 80 amp panel. 100 is usually minimum. Older houses didn't have the higher electricity demands, like we do now. Cmh is a good start. If you keep the veg room small you might be able to air cool it. Concentrate your a.c. on the flower room. Window un it's are ok, mini splits are better. Avoid portable ac

Hey bud. Not sure where you are at, but upgrading electrical service MAY start to open a can of worms. Will probably have to pull a permit through county or city. Which will then lead to a reason for wanting to upgrade. Some ideas would be planning to add a swimming pool, future kitchen remodel or an AC upgrade to a more efficient unit.

Packer, yes 80 is rare however, the smallest service locally anyhow is 60A. Typically for trailers... the smallest service I personally install is 200A or 2 150's... yes times are changing w our society's need to be plugged in to everything.

I doubt upgrading an 80 amp panel is going to raise to many red flags. I would love to have a larger panel, 100 amps works for what I have but it's close. I don't run my grow in the summer.
