i fugured by now someone would have helped.....do i need more info??wtf

your safe untill it gets higher than 85. If youve got the money, you could get an air conditioner.

hi Soon,

Your temp is fine...... 77 is perfect !!!
What you need to do is get your HPS closer to the tops of your plants... Your buds will seriously increase in size.. more than double, if you can get the HPS to within 12 inches or less of your canopy. 4 feet is way to FAR..

It sounds like you have a nice system with plenty of fans and air flow...

Sorry for not helping, but this needs to be said!

Garden, I love your avatar!.. But where did you find that picture of me?

gotta say thanks to u who answered...to u who didnt is it because i have no pictures? i hope the high temp will stay no problem what about in the flower cycle though? will it be too hot then?i've switched to 12/12 now and am about 4 days in...will the high heat slow down the sexing? little nervouse about the room still after this show ill be punching new vents to get rid of the long intake ducting run......will get pics one day

I would love to help you, but I'm only a noob myself!:p

Sorry..!:)

I just had a little tid bit of advice to pass on. You mentioned that your intake fan was a lot bigger then your exhaust. This will result in the room being slightly pressurized. If the fans were reversed the room would be in a slight vacuum. This means that any leaks would cause air to rush into the room and not out of the room. This is a great practice for people with worries about odor control. Also whenever you open the door to the room, air would rush inside instead of out. This would also help on odor control.

As far as your temps, I think you'll be fine. The lights are a a bit too high. I tie a string to my reflector and attach a weight to the end of it. The string is exactly 18" long. This allows you to keep the light at a constant 18" from the tops of the plants.

In the summer months perhaps you could use a window air conditioner if youre worried about temps.

Hope some of this helps.

you should hook up the cool tube A.S.A.P. you need to check out Mellow Mans cool tube thread in the FAQs section and Turtle420 thread in the indoor closet growroom section I'm pretty sure the cool tube thing would help you out big time cause I'm have the same problem but all I need to do is make a few adjustments to my cool tube and I'll be fine I hope. ;) I dont know if you also said that your exhaust fan was at the top of the room because heat does rise so a good place for the exhaust would be at the top and intake at the bottom like you have :thumbsup:

right on SativaGrowin...makes sense about the fans...funny how just a hint will open the doors to new ideas....how didnt i think of that??lol as far as the Cool Tube i did make one out of the pyrx barke a round as well but i am not sure if i have to hook a seperate fan up to it and Tee into the existing exhaust or can i run the rooms Exhaust through the cool tube?? i am not using Co2 yet so thats no problem....My exhaust is in the right upper corner right near the exhaust fan above the light....another thing with the cool tube with running a 1000Hps what sized fan would be a suggested to cool it adequetly with?? thanks for all the input so far guys....we gotta set up a northamerican Bud Bowel one day too see whos the best...still thinking up here in BC must still be decent compared to some no?? anyone have any ideas on that?
