Re-routing or splitting A/C ducts, how difficult?

I'm trying to get my closet setup wrapped up, but temperatures continue to be an on-going battle.

I have a SJ DR60 w/250w HPS. I use a 400+cfm 6in inline fan w/ a 6" Phat Filter (tent is 2x2x4, this fan is overkill, as intended). The filter is in the tent, the exhaust goes into my attic where the fan is located (had to, it's a loud fugger).

At lights on, I set my A/C at 74 or 75, depending. The ventilation in that bedroom is not the greatest, and even with the closet doors open, the ambient air in there is more around 77-78. That puts the temp in the tent at ~81-82 range, which is certainly higher than ideal.

As stated, I want to finish up the closet, which includes installing locking doors, which will, of course, make temps in the closet even higher!

So the thought struck me that if the CLOSET had an a/c vent, my problems would be over!! Set the house a/c at 75, and if it has a vent in the closet, the closet should get nice and COOOOOOLD by the time the rest of the house reaches 75.

Ideally, what I would like to do is SPLIT the duct that exhausts into that room, and run another line of ducting that dumps into the closet. Obviously, I can't call my a/c dude to do this for me. So the question is, how difficult is it to do, and what is involved?

If a SPLIT is to difficult, or not advisable, I'd be willing to MOVE the duct to the closet, which really shouldn't be that big of a deal, I figure. If the duct is too short, I'm sure I could splice on some additional ducting without any major issue.


I'm hoping that the answer is SIMPLE, and that the only problem will be squeezing into the tiny crawlspace that some sick bastard decided should serve as my attic.

Any thoughts, tips, pointers, or links to online references will be much appreciated.
 
Do you have a home depot where you live?

I am working on something similar right now. I have a vent in the room I am working in though, I just need to run a line across the room.

I just went to home depot and was completely inspired by all the parts on the shelf. Figured out my plan that way.

Besides a bunch of flexable ducting, connectors, metal duct tape I found some real neat in line fans I will be using.

Check these out.

Hey BBB, yes this will work, it worked for me. I tapped into a vent tube and ran another into my closet veg area and with it being so small boy it is nice and cool in there all the time.

You can do this bro it's easy, find the closest vent tube to your closet and cut it and install a T fitting into it and run your new vent with flex duct. If your house has rigid type vents you will have to cut out a section to add your T but if it is flex you just need the 1 cut. Seal everything good with the real aluminum duct tape (the metal stuff, not regular duct tape) and sit back and enjoy your cool room. Needless to say whatever run you tap into will suffer a little loss of cooling but you can add an adjustable vent in your closet and this helps dial it in more if you like. :friends:
 
Thanks guys!

You're right, everything's right there at HD & Lowes....I might pick your brain on specifics later on, and I'll probably use one of those duct fans in the run too, though it might not be needed, it'll be pretty short.

I'm dreading doing this, because my attic isn't an attic, it's barely a crawl space. Crawling in to run the exhaust duct was a NIGHTMARE! Just getting up and in there is a nightmare in fact.

The good news is that I'll put this duct on the close end of the closet, which can be reached from the entry. The outlet I'll be tapping is in the bedroom that the closet is in, about...8 feet away. I know that it's flexible insulated ducting, I'm guessing 8". I'll have to pop up and take a closer look, and figure out what parts I'll need. *groan*

I know it will be worth it though.

Thanks again!
