Need Help w/Cooling 5x5x6'8 tent 600watt

ive never seen a 5x5 tent with ONE vent...thats nuts
Hey buddy so I need some help another quick question

I'm changing my tent to this one

http://www.amazon.com/Apollo-Horticulture-Hydroponic-Indoor-Growing/dp/B00H9NGP8C/ref=sr_1_4?ie=UTF8&qid=1405497370&sr=8-4&keywords=Apollo+grow+tent

And I got a little booster fan

http://www.amazon.com/6-Inch-110VAC-250-In-Line-Duct/dp/B0007N5LI6/ref=sr_1_4?ie=UTF8&qid=1405497447&sr=8-4&keywords=Booster+fan+quiet

I was going to use this little booster fan to cool my hood because this new tent has ducting holes straight across so I can run it straight across and have my inline fan hanging up disconnected from the hood how I have it now separated.

I'll post pics later when I get it and set it up

I was wondering should I use another small booster fan like this one it's small and quiet and cfm is 240 to blow cool air in the bottom through the bottom ducting this tent has to keep tent cool or will leaving the flaps open be good?

So in the pic ima use that booster fan to run ducting through just my hood and keep just filter and inline hanging and coming through the top.

In other pic would I need another small booster fan to connect through bottom ducting hole to blow cool air in.
I have 2 fans in the tent already that I use

Thanks again

From experience, those little booster fans won't cool a 6in hood, I tried on my first grow and ordered a big fan after 15 minutes of monitoring temps. Let's get right to the issue though, indoor growing will usually require air conditioning in either the grow room or the surrounding area.

You definitely have enough equipment to blow the heat off of one 600w light, but without a source of cool air you'll be looking at whatever temperature the room is plus a few degrees from your light and your equipment no matter how much air you move around.

I found a used 12,000 BTU portable unit on craigslist and purchased it for $150 ($600 retail, listed for $225 on CL) and it has been working really well (do not buy a used unit from a grower...find someone in a wealthy neighborhood whose central A/C went out for 2 weeks). This unit cools my flower room (4 x 600w in 10x14 room). Can you believe those 4 lights are cooled by one 6inch vortex fan? That fan draws from another room because I didn't want to just suck all the A/C out of my flower room, but that other room is also air conditioned (mostly because it is my bedroom and I like sleeping in air conditioning when the house is 86, but also because I pull air out of it for my veg room). The portable unit is also a heater, which helps in the winter time because I have isolated the flower room from my house's heating system.


Long story short, my flower room is 74 with 4 x 600w, a dehumidifier, and 4 lumatek ballasts in the room. Lights off is 68. These temps are the same whether it is 92 or 80 outside and I frequently leave for 2 or 3 days....even if I couldn't see the room temps online, I'd still leave confidently. I would benefit from having a 14,000 BTU unit, but for the price I paid.....I'll take 74 with it running non-stop.

I included a couple pictures, but I don't claim to be an excellent MJ photographer. Ok, so first is a cheese plant at about 6 weeks. Second is blueberry at 4wks, third is train wreck (with slightly burnt tips) at 4 wks. Fourth is aerial shot of my room, fifth is a slightly different angle. Sixth is a 60x phone attachment shot of the cheese plant in the first picture (just started week 8, flushed, will be harvested in next 5 days). The photo makes it hard to tell, but there are some scattered amber, a lot of cloudy, and still a high percentage of clear trichromes (my patients have never complained about the effects from harvesting this cheese strain about mid week eight, I would take it right now if I had gotten my flush in sooner, very uplifting and energetic).

Happy growing man, whatever the tone of this ended up being, GOOD WORK! Your setup looks awesome and being willing to move everything into your bedroom tells me you care enough that you'll end up doing just fine! Find some cheap A/C and you'll be rocking!

In my experience, as long as the air coming into the tent is below 75 degrees and your running an air cooled hood, keeping the tent cool shouldn't be an issue.

I definitely recommend running and active intake. I use a 400cfm 6" fan on a speed controller for my intake AND exhaust. I can get away with running a 220cfm 6" fan for my air cooled hood. That set-up keeps my tent just a few degrees hotter then the air coming into the tent.

The room the tent is in isn't air conditioned, but I drilled a 6" hold in the door and I use a 6" fan to pull cool air from the air conditoned part of my basement into the room. I keep my central air set to 72, and it never gets hotter than 78degrees in my tent.

Thanks for advice so I ended up doing this
 
So I have just inline and filter separate I'm not using it because it's in veg and not smelling so saving me a bit for now in old set up was on connected to hood so was on when lights were on

Now I connected booster fan to hood at end as you can see and it keeps hood cool to the touch and have that running when lights on only 0.45 amps

Temps up top 84 and below 82 my room is around 80 I leave my windows opens and this tent opens from 3 sides so I leave all 3 open for fresh breeze during day when home have my bro watch them

I would love ac would definitely help but can at the moment to much electricity as it is in my room and bill already up to much

Most looking good a little deficiency but hopefully gets better flushed a week ago and soil ph down input some dolomite lime in all the pots an inch deep trying not to damage roots and hopefully raises and fixes it. Now light feeding and some cal mag

One in middle is a monster out of 9 pheno's #4 and #7 killing it want to wait a bit more to flip it's been in veg for 7 weeks until problem gets better

Soil not drying up that fast anymore any advice

For the soil not drying, you could use smart pots or another fabric pot. Other than that, it's based on plant growth and relative humidity. Speed up the plant's metabolism and you'll speed the rate at which your pots go dry....which brings me back to the A/C, which may be beating a dead horse.

For the A/C, I get it. My bill just came and it is $400, not fun at all. I sat here in the dark for my first few cycles because the only thing I could afford to run was the grow room (no playstation, no computer, no oven, desk lamps, chargers unplugged, etc). http://mjgrowers.com/book_what_temperature.htm there are a number of sources that talk about temperature, but the important thing to remember is that temperature not only impacts the plant's metabolism (ultimately impacting yield), but also the quality of your end product in terms of bud density. The other day I actually complained that I always needed a grinder and couldn't even break up a dube with scissors....I'm spoiled dude. For me, the cost of stretch and wispy buds outweighs the benefit of saving money on A/C, but if my quality decreases, so does my price at the dispensary and my feedback from my patients. I've been in plenty of 82 degree rooms though and you'll do fine if your humidity is on point.
