Exhausting through the wall?

I think I have a tiny bit of idea of what your talking about then. Do you mean place 2 new studs on the top and bottom of the new vent hole? Or on the left and right side of the new hole? Im assuming Im putting more boards in for support?

Though the last sentence "would only cut out a section, place two new studs, screw the drywall to them and make the minimal drywall repairs for screw holes." confuses me a bit.

What would happen if I just straight cut a hole in the wall, and the wood beam above the door?

To the left and right

The drywall is screwed into the studs if you just rip out the stud the drywall is coming with it. Just cut the stud in the middle for the vent, lightly tap it to check for any screws. If there are screw in that section of the stud they will "pop" on the outside of the drywall, then you can remove them with a screwdriver to minimize tearing or major drywall damage. Also the benefit of this is the hole left in the drywall if any will be where the vent needs to be cut out.:wink:

You could do that, you would need a power saw.

Newgrowth, I think I understand more of what you were talking about originally. Correct me of Im wrong.

You were saying that I should take out the entire drywall paneling above the door. Take 2 more 2x4s and create a opening large enough to fit the vent so there is still support. Remove the middle 2x4. Reinstall the drywall with the vent hole?

That seems rather complicated. Wouldnt it be much easier to cut just cut through the wood? And would a jigsaw work if I went that route?

I just wish there wasnt a stud there and I couldve saved myself all this trouble :-?

No you don't have to remove the drywall panel. Just cut the hole like you said for the size of the vent.

Newgrowth, I found something that might help a bit explaining what I need to do, but Im not sure. Do I need to remove the hole entire drywall side, and cut the wood, create a wooden frame, and replace the drywall and vent?

Cutting A Door Opening In An Interior Non-Structural Wall

This is starting to seem so complicated now...

The vent is not heavy enough to really require a frame to support it. They make sliding aluminum supports that tie into studs. Just place a bead of glue on the drywall side of the stud and toe-nail it into the top and bottom studs. Mount the vent in the location of the hole you cut for it using the aluminum supports.

It's not complicated they design the hardware to make it easy.

I havent read the thread but if it helps I vent and A/c and my lights into the cieling of my apartment(no attic but about 2 feet of space in between floors) via a hole i cut. This could be done the same way via a hole in the wall. This is the best thing I've done for grow room keeps my temps at 72

Removing the room altogether isnt an option. Since both our parents have already went to the house and looked around. I am even worried that putting a vent there will be suspicious. That they might notice that there wasnt a vent there before. The second vent on the bottom for the intake Im just planning to cover up using a small stand.

Natrone, venting to the ceiling isnt an option, everyone has said that mold will grow in the walls which is not an option.

Newgrowth, I couldnt find any pictures or anything on homedepot about the supports, think you can find a picture? Im still confused about how the proper way to install a vent and cut through studs. But you think it would be fine to just cut a hole for the vent with a jigsaw?

I want to do this right, and not cause problems down the road

Sounds like you have the right idea but not the experience to do this project. Try cruising some DIY forums to find examples of installing a vent, or working around a stud, etc. They usually come with detailed instructions for the weekend warrior and quite often good pictures.

Do it right and the folks will never notice a vent. If you're really worried put something else in the room that will draw their attention; huge-ass TV, 200 gallon reef tank, hot Checkoslovakian exchange student, you get the idea.

I'm just reading this thread for ideas for myself, but I have to say that I kinda sorta agree with the previous poster (is that Spicoli?). YOU think your parents have noticed how many vents are in this new home, but it's very, very likely that they have not.

Close your eyes and try to recall how many vents you see in anyone's home? People are just not THAT observant. If your parents were in there, they were probably focusing on other things rather than on vents. Did vents come up in conversation or something? Father or father-in-law has experience with HVAC and would definitely notice something?

If so, maybe you ought to use a closet upstairs anyway. You said that there were no upstairs neighbors, right? If you are convinced that vents are going to be noticeable to others, maybe this is not the right closet for this project?

Just wondering???

Also, NG is right about the stud. Studs are what hold up walls/drywall. If you cut the stud, you just have to make new supports for the drywall. It's not nearly as difficult as you're thinking, but you do need to make sure you provide support for that drywall if you cut that stud.

Natrone, you vent into the walls? Any problems with that?

Alright, thanks for all your help guys. I guess Im just gonna take a go at it with a jig saw once we get the contractors out of there and I have more time. Ill try to post pics as I go along, so maybe someone can learn out of all of this if I make a mistake

Im having trouble finding a good setup for ventilation to use with my cooltube and fan. I found a pic online, that could work but I dont really want to cut so many holes in my wall. Though they said that this design is good because its using outside air to cool the HPS.

Im wondering, is it OK for just the light vent to have an intake and exhaust through the wall? Since the intake air wont have high RH, and its the same air thats coming in and being exhausted is that safe for the interior without causing mold

Then my only concern is that since the air and exhaust is between studs, will that cause a problem?

How essential is it to have outside air cooling the hps?

Yeah you need outside air, it allows you to completely isolate your lamp from the grow in a cool-tube. If you pull air from inside your room too cool you lamp it will be less effective but can work in some situations. e

I figured its about time I posted pics up of the finished product. Been veging for 5 weeks, 3 weeks under cfls, last 2 under hps. Only been flowering for 3 days. The chocolope, mango, and i think the g13/buddha has shown pre flowers. I might have an actual ratio of 1:1 male female.

Nice man! Glad to see you have it all set-up. The vent looks perfect too. I really like to see grows come together like this . . .:weed:

Yeah, thanks for all your help. The right side has a return vent. It was stressful setting it up atfirst as I had to cut through wood for the top exhaust vent. The bottom intake vent I was able to find a vent exactly 9 inches wide, and I crammed it in there so I didnt have to cut through wood. I set up a separate veg chamber also.

Now my only problem is heat after I set up the veg. THe axial fan I have def isnt strong enough. Im getting temps in the 90-93 where you see that temp guage. Though at the base of the plants, the temps stay 80. And inside the veg chamer, the temps stay around 83 also. Wierd how 2 ft make such a huge differnce.

I got a large hydrofarm inline fan, but its WAAAY too loud. Im trying those S&P mixvent fans, hopefully that will fix it.

Thanks alot new growth, couldnt have done it without you. Now if I could figure out how to give rep

Thats great man, blowers are by far the best fans, they are quiet and move lots of air. Try an Active Air or Dayton brand blower, both quality products that will not let you down. :peace:

The one I got now is active air from Hydrofarm, but its way too loud. It can easily be heard through the door
