The Wrath of Summer's Heat

Hello Everyone, first time post. I've been a long time spiritual user, plant butcher (gardener), and medicinal plant grower. However, this is my first run indoors.

The summer is scorching, 95 degrees and up during the afternoon, mid 80s during the night and early morning. I am going to run my vegetative from 6PM- 12pm to combat the heat because my room is airtight / lighttight; yet I still want to lower it because with the light on it still gets to about 83 F during these times, and during midday with my ventilation system running only it doesn't get below 80 F

Here is my set up 4 1/2' long 2 1/2' wide 8' feet tall:
250 CFM blower facing down opposite exhaust
465 CFM exhaust (vents into attic )
Passive vent on bottom
Few fans for air circulation
400 watt MH agrosun with aluminum reflector
400 watt Lumatek Digital Ballast

I am on a budget at this point, and was hoping someone might have some suggestions.

Thanks in advance

Summers over my neck of the woods gets really hot 110-115,its 95 at midnight still so heat is definitely an issue for me,I switched my light cycles to night time 10pm-10am for my flowering room plus I had to buy a window A/C unit,which is working like a charm.I have a separate vegging room that is on 24/7 but I only use fluorescent lighting which dont produce much heat.

I don't exactly know the specifications of inserting an A/C unit. I'm limited to an area of about a square foot for discreet, efficient intake. I don't think my neighbors would appreciate a hole in their wall . I think that I might have to get more ducts, a few splitters, and a legitimate hood. I bought the excessively large exhaust for a reason, I may as well utilize it. Because I put a mercury thermometer on a string about 6" under where my lights are. And when the light is on, it gets around 94 F.

Thoughts? Thanks for reading.

You have the inline fans all you need is air-cool hoods which are a must for controlling temps in your grow area.You can find good deals on craigslist if you check daily for deals.What do you have for odor control????

I was going to improvise for odor control when it actually becomes a problem. Try making some carbon filters, y'know? I'm still waiting for my seeds to come. I chose wonder woman from Nirvana, which should be able to put up with a bit of the heat. It's been about 2 weeks and they still haven't arrived. Perhaps something about it coming from the netherlands to a black woman made them skeptical.

I'm just fine tuning my grow room before they get here, I've invested too much for it not to be ideal.

If your seeds haven't come yet then email them to see what's up. My seeds come 7 days exact to the day I order. I call it the 7 day theory. and goodluck

Try attitude seed bank.Go to youtube and search DIY carbon filter.You can get everything you need at a local Wal mart and home depot at a very affordable price.

You can't lower the temperature below what the intake temp is, if the air coming in is that hot, you need to cool it somehow. Heat exchangers can be made with copper pipe, rubber tubing, an oscillating fan, small water pump and a chiller/bucket full of ice water if an a/c is impractical. Here's an example and there are lots more on that site if you look around http://www.gmilburn.ca/2005/06/15/petes-homemade-air-conditioner/

Thanks for the advice guys. I gathered some funds. I think I am going to split the passive intake using a splitter, one down above a bucket of icewater with a water pump and some tightly wrapped copper tubbing extending to it. The other is going to connect to a legitimate hood (maybe with a cool tube?). The other end of the hood will connect to the exhaust with another arch to suck the excess heat of the ballast. Wish removing it was an option.

I'll figure out something more permanent when I have the resources.

Thanks for all the feedback everyone, respect to you all!!!

Be back with pictures possibly before and afters.
