Need Help with HEAT.
LN, I have to disagree with you on the air temp. Gotta be 80F & down w/o CO2.
I have a pair of 1000HPS in only 500cu ft. Keeping temps down was a constant struggle in early days with this op as a/c isn't electrically feasible for me- have to rely on airflow- and a long duct length/bends are unavoidable in my case. I finally got air temps to cooperate (75-77F) when I installed a centrifugal exhaust blower and a second axial intake blower.
Still, for a few weeks in summer, my intake air can be above the 75-77 sweet spot. The ventilation system will keep the op air temp to at least as the temp of the ambient intake air.
However, when ambient temps wander up above 80F, my top colas, closest to the light, tend to 'bolt,' 'run' or grow thin strands of buds rather than the usual tightly-packed, dense buds I get when the temps are cooperating.
My next project is cool-tubing the 1000s to try to get through next summer without losing half the yield of my top colas.

Good info AL, I had a small space to cool so my cola's did alright. A/C kept it down when light was on. When I can jump back in I will keep more of an eye on that. Humidity is what I had to fight the most.
I want to cool tube also. I guess it's a must with larger area. Don't want to lose out on the weight. I like dense buds.
Thanks for the correction, it's all about learning.

LN, I wouldn't have said anything if the battle for the correct temps in my op hadn't made so much difference.
Lucky you with aircon!
I use a dehumidifier to control RH when the temps are too low to trigger the exhaust thermostat (i.e. wintertime, lights off). The dehumidifier makes a bit of heat which brings temps up a little. When the room temp exceeds the thermostat setpoint, whether from lighting heat or from the dehumidifier, the blowers kick on.
You can get humidistats which you can parallel with a thermostat to control the exhaust fan, but if the ambient temp is low and the humidistat kicks the blowers on, it would cool the room below the usually acceptable ranges. I find the dehumidifier helps keep both temp and RH in range.

I went to Lowes today to try and find that $100 A/C unit. They told me all they carry are the swamp coolers. They call them Air Coolers. These are not A/C units. A/C stands for Air Condition. Is the swamp cooler what you ment? They have one for $139. My Humidity is 30% so I should try and get that up, right?
Thanks both of you.
I learned a lot from your information.

Where the hell you live, bro? Bumfucktegypt? I've been in and out of Lowe's a lot lately and I've seen the $99 - 6,000btu - air conditioner a whole bunch of times.
Go to Lowes.com and you'll find it there. Print the page. Go to Lowe's. Tell them "This is what I want!!!" If they say they don't have one, tell them to order it!

Hahaha.. I live in a good sized city that gets hot as hell in summer.
Thats, I will check out Lowes.com.
The Morons at radio shack told me three times at three different stores they did not have that 60x-100x mini microscope also. Someone gave me the page with it, I printed it out and walk in and the guy said, we are out, I said can you get the INV number, They had it.

Funny you say that, PSB is using one in the desert and it cools his room and only raises the humidity to 65% and that's great for plants.
Yes you sure do need to be prepaired for mildue or mold but a vapor pot does the trick and even will deal with spider mites too. It changes the Ph of the outside of the life to the point where they runaway and stay away. The ph change does not affect the plant either but they do cost about 125.00 bucks too.
Look you can always pick it up and try it for a few days and see where your humidity goes, then take it back and get an A/C that will work.

Lowe's has a real air conditioner, for $89 (5,050 BTU). This is what I just bought today. This unit will cool 150 sq ft room. AC units work a ton better then a swamp cooler.
Oh, and do not listen to the hired help when they say they do not carry them. They are were two isles over from the swamps.
Here is the link to this AC unit.
5050 BTU Mechanical Window Type Air Conditioner
Thanks for the help everyone..imp:
