  2. buy a cheap 20 in box fan, plenty of fresh air and and builds stalk strength.
     
  3. i have an inline fan and a 20in box fan for my vent. sys.
     
  4. ok cool..ill look it up...but thats one of the things i need to work on...my venilation...how exactly do u venilate?i have a whole bedroom but im only using a corner of the room and the room has 2 windows.
     
  5. check out the link in my sig, the youtube video.
     
  6. You'll need to read more on this forum... Read all the stickies!!

    But for the ventilation to work, you have to have the grow partitioned off, or sectioned away from the rest of the room....like a room within a room. The an inline fan can be used to pull air out of the "room" within a room. It's all about intake and exhaust.
     
  7. yea im learning everyday..ill make sure i look at some stickies...so what would be the best and cheapest way to section off the room?
     
  8. i assume an air conditioner is out of the question? heres one thing you could do- turn your outlet fan into the room and place a bowl of ice water in front of it. it sounds ridiculous but youd be surprised how much it can lower the temperature especially in a small space
     
  9. The tent works best when using negative air pressure to pump out the hot air and pull cool air into the tent. I have a 600w hps, 435cfm blower and I vent into the attic. My temps in the tent are within 2 degrees of what they are outside the tent. My tent temp right now is 76 and my house temp 75.

    A fan is not going to fix your problem. Its just going to move the hot air around. You need to move the air from the tent to the outside of the house.

  10. for a 600 watt light seriously?
     
  11. 90 degree temps ambient temps are fine a 20 dollar fan will do you just fine until you have 500 bucks for a tent,inline fan and carbon filter.i rocked a box with two 400 watt lights with no problems.
     
  12. ok...appreciate it Ozzie...so i can buy that poly and then support it with 2x2 wood..cool..then i can put all the venilation in..would it be a good idea to try to put at least one window inside the poly?

    Please don't get busted =[. You don't want any light going outside, that draws attention about the strange orange glow from the neighbors house....
     
  14. have u considered moving to scotland? just foolin- u askin in the right place tho, good luck
     
  15. ok..and i really dont wanna buy the grow tent cause i really dont have the money..i would rather just section a space off..ill probably end up with bout 6-8 plants in flower so i shouldnt need to much space.and by the way im grow mid grade bagseed and jack herer
     
  16. Yeppers. When I first got the tent i tried it without anything. Temps went up 15 degrees. I then tried a cheapo 235 cfm inline booster. Temps were 10 degrees above room. The 435w blower solved all my heat issues.

    Plants grow very nicely at 76-78 degrees.

    Good Luck man.

    Fyi... My link in my sig is to my current grow. 600w hps & 4x4 tent. See for yourself.
     
  17. ok ill check it out man..so this is ur second grow old dude in pain?how much did u yield ur first grow?also the 2 big mid grade plants in the pic are growing pistils?does this mean they will be female?
     
  18. follow that thread till the end. All 6 plants are about 2 weeks or so from harvest. Lots of pics. My first grow was bag seed. 6 plants got around 200g dried. Expecting a pound this time. I have colas as big as my arm this time. Did it all on prefertilized soil and about $4 in nutes.
