Ok So I'm on my first week of flowering(just switched the lights Sunday). I vegged my plants for 4 weeks under a 430hps(10 small 15"-28" plants).. I this weekend picked up $1200 worth of equipment for $180=) so I decided to upgrade the 430HPS to 2x1000wattHPS.. I havea 6"ecoplus fan pulling air from above the reflectors(I'm planning on going to the local hydro store today to buy glass and the end pieces to plug the reflectors directly into my fan.....)
Now when I flipped the lights I added in a 3ft tall mother plant I want to flower so it's under a 1000hps all to itself right next to the 10smaller plants..under the other 1000whps
(grow room is upstairs bedroom approx 12'x15'
Now presently I'm getting close to a 10degree flucuation between night day temps between 68* and 78* during the day. In order to maintain this I'm having to run the house fan/a/c in order to keep my upstairs at 69-70 to maintain the temp in the grow area...I also leave the door open with a large box fan in front blowing air in and 3 oscillating fans in the room...

My future plans are for a 6"Intake fan(maybe change the exhaust to 8" or just have 2 6" ones)...

Questions

1. Will the glass and hood vents be sufficient or will I need another exhaust fan???

2. In order to maintain my temp at night what size space heater do I need?ANy recomendations??
3. What size A/C should I get for the room.. MOunting through the wall or out my window is not a option as I do not want to draw any suspicison(sp?) on myself(no need when I have central a/c (right)=)...

So presently this is 2x1000watts lights in the flowering area..I'mm be partioning off half with tarp this week to introduce 30 clones in to start vegging.. I'm planning on vegging them under an additional 1000whps to begin with and probably my 430w hps as well...

ANy an all suggestions would be great....

My goal is to be able to ALWAYS leave my door closed of course and have constant and fairly accurate control of the enviroment within the room.. I have a few temp sensors so I can hook up a A/c on one and a heater on another.. I think Im going to need to upgrade the wiring though in there I had to run one of the 1000w off the room next to it...


winter temps around here I'd say average 40-50?northern california and summers are up to 100+

I'm having the same problem with the northern california heat. It was around 97 here today and it's not gonna get better. I have 9 afghani kush vegging and my ac only starts to cool the room where i need it when the sun goes down... : ( If anyone sends you some info on that situation, hit me up.. Oh, I would recommend 6" ducting hooked to a high velocity intake fan to cool those 1000 watters.. I gotta 1000 hps and even just having a regular fart fan (bathroom vent) works wonders 95 cfm.

1. Run your lights at night when its cooler.

2. you dont need a heater.

3. you dont need 2 1000w lights.

4. above 55' and below 90' and you will be fine, no need to be obsessive about controlling temp

I veg 24 hours a day so I can't just run everything at night. Picked up free new a/c unit and it kicks ass. Comfortable 78 degrees nonstop baby! woot woot!

cool tubes will drop you down temps quite a bit. personal experience, 600 watt hps in a 4x4 closet. 95*f temps. introduced a air cooled hood temps dropped to mid 80's. AC and/or heater will be rated by btu. btu is calculated per your cubic feet of the room. google for a btu calculation. as someone said and most of us practice, run your lights at night time. i personally do not suggest 6 intakes. with so many intakes you make it very easy for bugs to thrive in your room.

make sure to have screens on your intakes and exhaust. because of running lights at night. bugs attract to light. and its just a good evestment. much like me taking spelling classes

Fuck nor cal heat man, its 108 up here today! So I had to break out the old portable A/C 8,000 BTU unit i got. I run the exhaust from the A/C straight into my hallway and leave the central AC on as well.... I am able to keep my closet as a brisk 75 So what i am trying to say here is portable A/C's kick ass.... would be at 95+ w/o it.....
