    Aloha,
     
    This is my second marijuana grow, ever, but i have years of experience around plants so i'm good in that department.
     
    I got some Super Lemon Haze seeds off of a buddy and 3 of 4 germinated and have been growing BUT their growth has been slowed due to heat
     
    Where i live at on island is hot pretty much year round with ambient temperatures in the room ranging from 88-96 during the day and as low as 79 at night; my grow closet varies between 82-92..
     
    The closet is 76"x27"x108" and the room it shares is 13'x13',  with a 6" 400CFM inline pulling through my 600w HPS cool tube at 65%.
    The closet is exhaust up in to my attic/crawlspace thing
     
    I have 1 box fan in the room with 2 more in the house but that has only helped a little bit. In the room the closet shares, there is a window ac that is on the opposite wall 13' away, but that doesn't effect temperature even a SINGLE degree during the day. I have blackout shades on order which i feel will help things dramatically.
     
    I have tried running two different intakes, one for light and a passive for box but that was ineffective with the duct booster fan sucking either intake. The only temporary solution is to keep the doors of the closet open until i can figure something out.
     
     
    PLEASE help, i have tried so many ideas and i am sick of throwing money away.
     
     
    Sorry if this doesn't flow very well, i am stoned.. :)

  2. If all else fails I'm thinking of making grow tent and building it around the window a/c which will allow for a tent about the same size maybe bigger. I have to sleep/bring chicks to this room which was way the closet was ideal but.. gotta do what you gotta do

  3. 5'x5'x'7' tent on the way, Amazon says it should be here by Friday. Once my plants bounce back from this heat i'll start the journal off :)

    Well, the tent is working, yesterday i had a 24hour range of 72-82, $145 well spent!
     
     
     
    Some changes that i have made:
    *AC is set to 72 with pipping blowing right on the plants. This creates enough of a breeze that i shut off my oscillating fan.
     
    *I have no exhaust running, just using passive exhaust to keep the temps as low as possible; we'll see how this works out in time
     
    *Kicked the light up to 75%
     
    *Dropped the light to about one and a half feet off of the top of plants
     
    *Added three seeds of unknown that i have named Joel. I started them in a small pot to experiment how much the initial pot size effects growth. There has to be a drop off point which too big is disadvantageous and you are just washing nutrients out, so i am playing to figure that out.
     
    *Rearranged the pots into two rows so they are now all evenly spaced.
     
    *Even though growth was retarded i am going to hold course and start nutrients at the beginning of week 5, 10/23.
     
    *FIM'd the two left plants to compare growth/yield to plant 1.
     
     
    *To Do
     
    *Carbon Filter (Don't know how i am going to do that with passive exhaust)
    *Muffle my damn jet engine in-line fan.
    Another idea i have is to get a speed controller, because i don't think i need a 450CFM fan, at full speed, to cool my 600W HPS.
     
    Without further ado, here are the pictures of my 3 week of babies which were growing slow as balls.

    As of 6 hours ago 24 hour temps were 62-81. I don't even understand how my tent could get to 62 whenever ambient temps were 79-90 and the AC is set to 72 :confused_2:
     
    The 3 seeds i added on the 13th have sprouted and are on their way.
     
    I also dropped the light down to about 2 shakas, 12 or so inches, off of the plants
     
     
    Whether anyone responds or not i'll keep updating  :hello:
     
  6. I currently have my plants up on stools to get closer to the light (see the pic 2 posts ago) with the thought process that the light should be fixed to reduce the length and amount of ducting. Now that i am building my SCROG (PVC & wire) i see that this won't work once i add the SCROG to the grow. 
     
    I have a good 7 foot of ducting on the exhaust side of the fan that leads to the window which is why i am trying to keep length to a minimum.
     
    Does anyone have any thoughts on the most efficient way to do lighting/plant setup?
