99.9 farenhiet

Thats how hot it is in my room right now or the thermometer maxed out. Dont know what to do about it. Dont have central air, a window shaker isnt going to cut it. I have fans blowing all over the place. This is starting to concern me. Going to be close to a hundred during the day around here for the next few days lows in the upper 70 at night when I run my lights.

The only thing I can think of doing next is putting a 6" fan blowing into the attic to pull more air out of the room that feeds my grow room. But I doubt that will do any real good. And probably wont bother with it.

I have some bubba in there right now. 2nd week of flower. I hope these dont get stunted to bad.

Were is the, Its so hot outside I ........... joke when you need one?

You have to vent out hair out and bring cool air in. What's your grow room? A closet, basement, a pc? At 95F+ unless you're pumping co2 into the room your plants are going to get heat stressed for sure. It's somewhat ok if you were growing outdoors, but indoors the conditions are a bit different. If possible I would seal your room, have a intake fan sucking air in from somewhere not in your grow room and another fan on the other side of the room blowing the air out. Your exhaust fan needs to be 2x the size of your intake fan. What type of fan are you currently using?

Actually what's your entire setup?

Never took the time to watch the movie, loved the book. I may DL that version.

what exactly are you working with? air cooled hoods help a lot. an ac will only help. fans just circulating are not going to cool your room, they are just going to keep your room at a more even temp. you need to exhaust that hot air and pull in fresh air. if that fresh air is hot than their is nothing you can do except get an ac or chiller. maybe, just maybe a lot of ice in front of fans will help a little. you never said your light source but if its hps, get a digital ballast that you can turn the wattage down. i have 600s and i have them at 300 now until my mini splitter ac comes in. good luck.

Its an small upstairs bedroom so that is why it is so hot always has been. Have an 6'' hurricane going through a 1000 and out the room and two t-5's in there as well. intake is the door with some strips of black plastic to cut down on light getting in it off of the darkened living room. I have outside air being vented through the registers from the basement window when it gets cool enough outside, no sense in pushing hot air inside. all the windows I can are opened. The hood air is pushed through the 1000 and into another room which is closed and then out that rooms window.

I guess I just wanted to let you all know how hot it is over here. I have to work with what I have and moving air is about all I can do. It is still about 80 degrees out right now so I cant get it under that if I wanted to.

Im open to ideas though. I dont have any other than central air and I cant do that . Just hope they are able to recover since it is still early and it stays cool.

I thought I was all for global warming but I guess I will have to re-think that.

Why on earth would you want global warming? Your best and easiet option would be buying a portable a/c unit. Home depot/lowes sell a 5000 btu for around $100. I'm sure there's some chart that tells you how many btu you need for your specific area, but 5000 btu is the lowest you're going to find. I'm not much of a ebay person, but I'm sure you could find cheaper if you look around. If outside air isn't cool(80F+) your main option is to cool the air you have. I'm not sure what "through a 1000" means. A 6" fan would be good for a micro grow like a sterlite/rubbermaid bin, but not for an entire bedroom. Again there's probably a sheet somewhere for the CFM you need per square feet, but for a room I wouldn't mess with anything less than 10"-12". I use two 4" PC fans that have 60(or was it 80) CFM as my exhaust and have a 4" passive intake hole. My temps are still in the 80's.

A 1000 is my light which is hooded. I have a 6'' hurricane pushing through that. Rated at about 435 cfm's. A portable a/c wont do it tried it before. A 5000 btu a/c wont cool much more than a small room with nothing in it.

I think I will put in that extra 6'' and vent that up into the attic to move more air out, to see if that helps any today instead of not doing it. I guess it would help some not enough but a little.

5000 is the smallest they make. You could get a 10k btu if you wanted. You've got to get your temps down to at least 85F. I don't think 1 more fan is going to drop the temp by 15 degrees. Oh 1000 watts, do you have a hood cooler or w/e it's called or just the bulb by itself?

just the bulb

Yeah its just hot out usually I can keep it at 85 but I havent seen 99.9 before and will be seeing it for the next few days thats for sure.

Well if you are still doing your basement grow then you got that.I would lose that 1kw hid and just use the t5's for 12/12 rooted clone sog.No veg...straight to 12/12 to keep the stretch within 12".You said it is allways hot up there so you have to make sacrifices and once dialed in you will be like "holy fuck!This alot better than risking a house fire!".

If you have a dimmable ballast, then dimmer down to 75% for these hot days. I'm running 2 600 watters with no cool tubes, and when I turn 'em down to 75% my temp stays in the mid 80's. At 100%, I was at 96 degrees. Not ideal for plant growth to lessen the light, but, niether is excessive heat.

go to a pawn shop and look for portable a/c unt i found a 10000 btu for 175

Stretching>heat stress
Pretty much all you can do dude is A:Get a portable a/c unit, B: Use less powerful lights, C: Get some serious ventilation.

I do

going to put the 6'' blower and have it blow from my room up into the attic. I have the carbon filter through the light and out with another 6''. A big floor fan blowing from a room towards my grow room. And I will have a fan in a window blowing in. And I have a blower blowing through my registers upstairs from a basement window.

It got up to/over a 100 last night. I hope to be able to hold it at 95. Considering everything I would be happy with that, better than over a 100.

really-

sorry to hear that. instead of having all the fans blow into the room, switch them to blow out, esp the window. that will suck heat out through a very short path. also, make sure your attic is vented well enough to handle the air, or your just fillin a balloon.

Unless you want to run up your electricity bill with an A/C unit, theres really nothing you can do.Upstairs in the summer is no bueno. Your buds might get airy and foxtail. In the end, you'll still come out with chronic, but quality and yield will drop.

If you have a backyard, consider building a little greenhouse with a white translucent (not clear) covering and run a fan/carbon filter in there to ventilate. Should reduce the smell and temperatures, and you get free light.

I've given up on indoor during the summer... The sun is free. Just keep it discrete

can you eliminate the t5s? or is your grow big enough to where you need the light coverage? 95 is getting better. im dealing with 85-95 right now no co2. at least powdery mildew will have great trouble growing. im noticing stress though. getting fucking pissed been waiting over a month for a mini splitter ac.

youre growing in an upstairs bedroom, and venting out a basement air register????

dude. if thats what youre really doing then you got to move shit around.

if you are growing in an upstairs bedroom, then you need to vent out the attic. heat goes up. if you are trying to vent hot air through the basement youre only concentrating heat upstairs.

if you have a basement you need to grow down there. basements are always the coolest area in the house. if you dont have a basement but meant a crawlspace then you should be drawing air up from the crawlspace and vent hot air out the roof.

clarify your situtation and i may have some hillbilly knowledge for ya.

answer this questionaire:

do you have a basement or root cellar?

is your region hot as fuck outside, or just in the house?

what is the relative humidity outside your house (approximate will do)

what is the relative humidity inside your house (approximate will do)

can you vent to the roof?

do you have a back yard, side yards or any outside area where nobody will ask questions about a strange looking device?

can you drop $200 bucks on a cooling system that will cool your whole house without using hardly any electricity and will last for a decade or more with minimal maintenance?

answer the questions and ill bring you the coolness.
