What's new

Thinking about the attic. Feedback appreciated.

Hey IC Mag folks - I am bothering you good people because I want your input on my idea. I have searched the forums for attic grows and haven't really found anything to help with my specific plan. I think it will work, but want some input, so here we go.

We recently moved into a new house and I really want to get a sustained grow back up. My problem is that stealth is an absolute must. I want to grow in a perpetual micro SOG style, but I really don't have anywhere in the house to set up an NGB multi chamber style cab or have multiple seperate cabs and remain stealth.

I have an idea to set up in an attic space. It is above the garage, laundry and master bedroom closet and has lots of good room. Since I know temps will be an issue I am hoping to grow in a couple of small cabs, like no bigger than 2 feet square cabs, 1 for flower (maybe like 150W CFL or so) and 1 for mums/clones (no more than 100W CFL, probably less). Probably build them with 3/4 inch plywood. I can pull in fresh conditioned air for each cab from in the house below.

So, what is your take on that idea? Do you think I can battle the attic temps, summer heat and winter cold, if I have a 6 inch insulated duct passive intake going to each cab, for pulling fresh air into the cabs from inside the house below? It would be easy, and stealth, to just cut a hole in the ceiling of the laundry room or closet and cover it with a vent cover to look like an air return to pull air up to my cabs. It's usually between 70-75f in the house. I would have a good fan in each cab, like the 120 CFM Delta I have now that I have to seriously undervolt so it doesn't sound like a tornado. The fans could probably be run at full speed in the attic and the noise, if any can be heard from inside the garage or the house, can be blamed easily on HVAC or something, the sort of stuff that should be in an attic, but that will be hidden away up there and no one would ever see the cabs.

So, give me some feedback on this. I have some Nirvana NL, Mandala #1 and Sam the Skunkman SkunkxHaze seeds just waiting for me to try this. (Thanks to Seed Boutique for getting these seeds to me so darn quickly, 1 week, was really surprised).

It gets REALLY hot in attics in the summer-well over 100 in the midwest. You're smart not to try cooling the whole attic.
Are you gonna pull in winter air into your cab?
Tried the attic some time ago- couldn't keep the temps down in the summer.
You might find this thread helpful.

Good luck.

Hey Jellyfish thanks for the input and the link, also read thru The Hornets Nest. Not even thinking about cooling the whole attic, just the 2 cabs for flower and mums/clones. So the real question is, if my 2 cabs, probably made from 3/4 inch plywood and about 8-ish cubic feet each, are sitting in the attic (100+ degrees in the summers, maybe 30 degrees in the winter) , but they are each getting passive air intake from inside the house (70-75 degrees), will it be controlled enough to grow in those cabs? Cab exhaust fans would be like a Delta AFB1212HHE, 120 CFM, Static Pressure: 9.00 mmH20, 44 dBA.

I'd say go for it. Worse case is that you might have to buy some foam insulation or something to cover the cabinets with. I'm imagining 1" or 2" thick styrofoam sheets cut into panels and tacked on the outside faces of the cabinets with spray adhesive (or whatever). 3m makes a spray adhesive that won't melt styrofoam.

You'd basically be making a disposable styrofoam cooler and filling it with cold air instead of ice. Cheap, easy.

The main issue in my mind is dealing with the rest of the process--if you're bubbling water to disperse chlorine, your water will be 100 degrees. All the time you spend tending and talking to your plants will be spent in a sauna. Not necessarily unpleasant, depending on your own preferences, but perhaps so. The cabinets are the easy part in this equation.

Cheers!

attic grows are the shit! best of luck with the heat. When i was a 15 year old stoner my buddys parents grew and we totally knew it. We could never find the grow op and we searched the entire house. they hid it in the attic with a fake wall.

gdiddy - I had that same thought about covering the cabs with styro insulation. The 4x8 sheets are like 12 bucks at HD.

igrowkushbitch - Thanks for your take. I don't know if I'll get into any fake walls, but the attic is definitely my only shot. And the wife will let me do it. She likes the end result, but isn't a big fan of having my current cab in the house.

Thanks for your takes mates.

Thanks Braddah. I am going to go for it. I really just don't have any better options for setting up the farm. It will take a few months probably to get it running. So my plan will be to have 2 cabs, one mums/clones/veg and one for flower. Both about the same size. Both will be very simple, made from plywood and foam board insulation. Intake will come from the house below the attic. Lights will be CFL. Exhaust with a couple of fat Delta fans. Run a perpetual micro SOG (Dr Bud style). I will also build a small 3rd box for drying. Now I need to get to some serious planning and building. The sooner I can move from my current cab running 12/12 from seed and into a perp setup with some good genetics the better.

If you have the space up there, make your cabinets plenty roomy. No reason not to. It might be easier to insulate and provide environmental controls on one big cabinet which is partitioned into separate veg and flowering chambers. Excepting the doors, it might be easier to insulate by stapling and covering the exterior with rolled fiberglass insulation. In a warm attic, you won't need a special drying chamber. Just a flat tray sitting on some rafters would dry bud nicely.

Since it is above the laundry you might be able to run a water line up there. You also might be able to tap into the plumbing vent pipe for a water drain to waste. Some people use this vent pipe to vent the air from their grow space.

I read on another thread on ICMAG that fiberglass is a no-no for grow chambers. Possibly not good for the plants, and definitely not good for YOU to breathe in fiberglass fibers!

yeah the attic is too hot and in most cases too small and hard to work in very cramped small spaced can really be a challenge for growing plants although I have seen them get done below a floor in 4' lol peace out Headband707
