My attic grow room construction

For sure bryant, are those sheets able to hold static? I didn't think about that before...I would assume not, but I know what happens when I assume. What kind of ventilation do you have planned after the blow out heals? that is no good either, you should try some aquarobics...

Your scaring me alittle with the static issue. What type of issue am I going to have if they do? i don't think they hold static. The little foam duct pieces that fall off when I cut the sheets hold static, i know that.

I'm basicly going to have the main room exhaust in the flower room hooked up to a carbon filter. Then have some sort of an intake running through the curtin.....some how. I will be bringing in fresh air from the hvac I tapped into and from my office below the grow room. The exhaust from the room will be brought through the roof. The exhaust for the lights will be dumped into the attic. Hopefully the heat from the lights will be dispursed enough that I don't have to worry about heat signatures.

I just had the doc give me a shot today in my knee. Its just an ongoing issue, i should be back up and around in few days. It just acts up every now and again.

Ahh ya I'm not sure about the static issues; I'm sure its not enough to be a threat and as long as there isn't an exposed wire just flying around, your clean setup is going to be ok.

That vent system sounds good, whats temp in there without anything on? I think that an oscillating fan in there would disperse the lights heat enough.

Ahhhhh, i see where you going with the static issue. No, no wires hanging out. And I will be installing drywall around the outlet boxes. Good catch though.

I'm going to run a cool tube, 600watt hps for the flower light. So I think I'llbe ok on the heat with that. The rooms still not sealed up, so the temps are all over the place right now.

Dumping the air from the lights is not a good idea. The heat will just build by the hour. Then your trying to cool the lights with hotter air. pull air from the eve, and exhaust out. push the heat from the lights out of the attic. you could exhaust in the eve, if sealed lights, with no odor. What is the average temp up there? Better if you chart it by the hour, over 24 hrs. You can tap into an A/C vent for the room? Not sure what latitude you live, but it can get 120+ in an attic. Trying to overcome those temps, your going to need a/c. during the hottest part of the day the room will be 85+ with a/c. The most important element in an attic build is ventilation.

i am doing almost the same build i am running my intake to pull straight through my air handler so whether its on or not its going to be pulling through the cool coil to help my heat issue.. and i am going to try to exhaust back into my house to help on energy costs after i see how hot the exhaust air is. i will let you know how mine works out should be another 2 weeks. i like yours a lot great work.

looks really nice man really profesional

Trust me, the heat issue has been on my mind for about 2 years now. I live in the south, so the summers get pretty hot here. There is a louver vent directly across from where the heat from the cool tube will be pushed out from. You can see alittle of it in some of the pics. I thought about dumping the air outside through one source, but I've seen too many videos on cops busting people by using the flir to see where they are dumping the heat from their lights. No air going into the grow room will be pulled from the unconditionded attic space or outside air. The air for the cool tube will be pulled from the closet in my office. I think I'll need to add an intake for the room itself from the closet too. Plus I have an HVAC duct run from the unit too the grow room. Plus the hatch I have to install yet might be left open with a large fan during the hot months.

I'm definatly going to try the chart idea. Thanks for the great idea!

I'll be honest, I have not seen anyone do an attic grow on this site from start to finish. I think why most attic builds fail is that the people don't insulate them properly and don't seal them up air tight. I have pretty much an insulation value of R-33 up there. If the ceiling was alittle higher, the ceiling and walls covered in drywall and had a fixed set of stairs, this could be a habitable room.

My lights and fans will be in this Friday, so hopefully I can test out the room this weekend. Keep your fingers crossed every one!

Yea that sucks but with the right ventilation and a trusty eye on them your cool

bryan228,
I am very interested in your exhaust setup. Please take a lot of pics. The heat is also my primary concern. However, with your impressive insulation, and if you seal the room well, I think you will be fine. I think an ac unit is necesarry but most can cool a 300sq ft room and we dont have anywhere near that area. Plus, we will have exhaust and cool lights. I am very hopeful!
Did you get anything done this weekend? I didn't cause of b-ball and visitors.
Finally, please continue a grow journal after construction is done. I'd like to see your strain and soil ideas.

this shits oFF the tap, SUBSCRIBED

I'm also very eager to see what results any tests produced. Hope everything is working out just like you wanted it too!

Sorry I'm late on the update. This project is just annoying me right now. But I'm at the home stretch!

Got all the taping done. Installed the door, which turned out better then I thought. And I finished my exhaust vents. I still have to install some drywall in some spots that could be firehazards, like above the HPS and around the elec boxes.

It got pretty hot down here over the weekend. Without the exhaust fan on, with just the air coming out of the HVAC unit, it stayed at 84. The attic over the main house got into the high 90s. With the exhaust fan on it got down to 78. So I'm pretty happy with it. I'm going to wait on buying the ac unit I think I really need it. I think if I keep my main house ac low during the summer, the room should stay about 10 degrees above the main house temps.

Below are some pics. It's ALOT brighter up there then shown on the pics.

interesting temp difference. I was wondering how that would work out. The christmas decorations in the last pic crack me up. Im with you on the grow room build getting annonying. I just want to get my light, soil, and seeds. Get to the fun part.

looking better and better every time you post, rooms going to look sick once its all done man. any plant you put in there is going to love you long time ......keep the updates coming.

I hope so. My mind is having a brain fart looking at how much money and time I've put into this. I just keep thinking about the pay off

They were about where I thought they would be. But summer isnt even here yet. I'm just pissed I didnt get this done sooner. But so far I'm happy.

Yeah, I got my house looking like the Griswalds at christmas. What type of progress have you made on your room?

Amazing Bryant, it really does look better every time you post something new. I say you smoke the hell out of your first harvest and then sell some of your second one to make up for all the money you spent making such a fine grow room. I can't wait to see what the room looks like when you've got it full of pretty sticky pot flower. I hope you have many years of year round growing until it's legalized and then many more years past that!

Sick build man, it's awesome and genius! I admire your hard work and dedication! It's look incredible. May the bud god's bless and reward you! Is that reflective insulation on the walls? Home depot here I come, seems to reflect better than black and white poly. Peace, keep it up. Happy growing.
