Hi everyone,
This is my first post over here.  I've been on the shroomery for almost a year and have grown mushrooms for a while.  I like to grow pot too, so let's get down to business.  Right now I have a 4x4 tent with a t5 with plants vegging and we are going to flower in a 4x8 with two 1000 watt lights.  I am in a 1br apartment with no AC so my climate control situation is rough.  Our whole complex is heated by boilers so temp swings happen.  I damn near killed my clones right when I got them because I threw up the t5 and it spiked to 84 degrees in the veg tent for at least a dozen hours and holy shit I was mad at myself for making a mistake like that.  Thankfully all the plants look like they are going to make it.  I got cold air blowing in from outside now to the tent and its sitting at about 75 degrees.  Should lower tonight when the temp drops but I'm just going to lower the T5 and adjust accordingly until I have true climate control.  Also the whole operation is in my living room which is a bit annoying too, but you make do with what you got. 

Here's the post I put up a little bit ago on the shroomery detailing my problem. Any thoughts, tips, and input is welcome.  I won't get butthurt if you tell me it's a stupid plan so long as you explain why!  I love to learn.  Anyways

Okay Yall I got a project I'm working on with my weed grow and I need some opinions from you guys if you think it'll work.  I have had to scale down to two lights since I'm in a 1 bedroom apartment.  The problem I'm having is with temperature control.  I am running my 2 lights off my only 240 circuit so pretty much I have to run my grow on a 120v circuit.  Also since my grow is in my living room a window unit is out, so I'm pretty much restricted to a plug in portable AC.  Luckily I can find them rated to 14000btu which I THINK should be enough to keep two 1000 watt lights and 1 T5 below 80 degrees.  I obviously am going to run my lights at night time. 

Here's an AC somewhere along the lines of what I want:
http://m.homedepot.com/p/Avallon-14-000-BTU-Dual-Hose-Portable-Air-Conditioner-with-InvisiMist-Smart-Drain-Technology-APAC140C/205037354/

So my plan for getting the most out of my AC (gunna need every bit of energy the fucker has for my lights) is to put it in a  plywood box.  Out of that box run fans with ducting to my flower and veg tent. I plan to build an exhaust box too that will be carbon filtered and have exhaust from the AC and the tents running to it.  From that box I plan to have a master exhaust that runs outside. 

I guess a picture is worth a thousand words so here is my drawing of the way the air will flow. 



And here are the boxes in detail.  I was planning on drilling maybe a 6" or so hole in the AC box to prevent a vaccum.  I don't know if this is really necessary which is why I am running it by you guys.  Here's a pic of how the A/C box will flow.



And I was planning on doing the same thing sort of except with a carbon filter attached and a carbon filter inside the exhaust box....like so.



And run everything out a back window.  This is pretty much a closed loop system.  Was just curious if you guys think it will work.  Invention is the birth of necessity or whatever.  I just don't really see any other way to adequately cool this motherfucker.  I also have never done much hvac work besides repairing a couple of units and that was all electrical. 

Any pointers would be appreciated.  I would just try to cool the whole room if I had more electricity available, but with this apartment I already gotta run my lights off the stove circuit and my fans off another circuit (or two depending on how many) and my AC off another circuit.  I also live in the bedroom  

The boxes seem necessary to me to keep smell in check, to make sure I get the most out of what little air conditioner I have,  and it will kind of work like a silencer too (will find a way to insulate it somehow)

I know one of you smart motherfuckers can help point out flaws in my idea.

I am sorry I should have clarified, it got to 84 out in my living room.

  OOOOOok....bit of a huge difference.

Yeah 70 to 80 is prime but having it in the 80s won't hurt. There would be no buds coming out of Mendocino and Humboldt if temps in the 80s hurt.

Yeah I see heat damage but I see more burning from overfeeding then anything. The heat didn't cause those leaves to curl in on themselves and look like claws.

Heat stress is like this. The leaves curl upward.
