So I just added 2 1000w lights to my room. It has raised the temps significantly. I was running 1 600w aircooled hps light and my room was always 74 degrees w/30% RH. I am running a 12000 btu soleus a/c in the room. the room is aprox 65 sq. ft with a 7' ceiling.. The a/c is a 2 hose unit and already exhaust heat out, but i think maybe not enough. Is adding another exhaust fan going to help lower the temps? my temps are staying around 85-90 degrees with the two 1000w running..
 
They are all air cooled.. I must need another exhaust.. Will an exhaust fan with a charchol can filter attached help to ehaust the heat? I wonder? PEACE
 
if you have it properly set up... the temp inside the op should be within 5F of the outside temp... WITHOUT AC...

Al B. Fuct illustrated it really well....













There are formulas to calculate the airmass exchange necessary...


But the way I learned it was...








if lights are aircooled... room volume excjanged every 2 minutes... as you are only looking to replace the CO2 that the plants used up....




If lights are bare... 5x the room volume per minute... as you are trying to get rid of the heat as well...






Now...




What are the outside teps you deal with?


What kind/size fan do you have for the aircooling of the lights....?


We'll figure it out... don't worry... ;-)

oh and the intake blower on that drawing is not mandatory...

In fact.. only 1% of ops NEED an intake blower....
 
Ok Here are a few picks. I hope you can see It's hard to get a good pic with the lights on... First see that I have a big can fan blowing air threw the lights and out the same vent as the air conditioner. Could this be a problem, venting to much air through the same excape? When I touch the "T" where the hoses connect it's frickin' hot. To hot to touch!! The lights really do not seem so hot to the touch for 1000w The last pics are of my first grow that is now in it's 5th week of flower after a 7 week veg.. not bad for a newbie I have been told.. I am so proud.. Thanks for you help..
PEACE

so the fan blows fresh air through the lights.... and joins the exhaust from your AC unit at that "T"....

And that "T" is friggin hot?

you need to re-do that exhaust ...

anyway you can put your AC outside the op, and duct the cold air IN....?

You need to get rid of heat sources in the op...

what is the outside air temp?
 
The air that cool's the lights is air from the room, not an outside source.. So it's taking air out of the room "I think" and forcing it out the same exhaust as the a/c thats why the "T" I did not want to cut another hole.. But I will..
 
AHA!

Dedicate one fan to the lights and one fan to the exhaust of your room...

Trying to cool big lights with HOT AIR is like trying to wash your hands with dirty water, bombing for peace or fucking for virginity...lol....

If you live in a hot place, dedicated fans are a MUST...

Not to mention that the exhaust should be on a thermostat, allowing it to shut off without shutting off the cooling to the lights...
 
Yep I think your right. I guess I needed someone smarter than i to hit me over the haed with the obvious.. Thanks PEACE
 
Well i did the fresh air threw the lights and it cooled the room 10 degrees. Next come the exhaust fan threw the filter.. Next paycheck..PEACE
