need help with ven. system?

any ideas or suggestions on how 2 make basic , but effictive ventilation system (for heat and smell) for a small closet grow.

Are you able to access outside air via a hole in the floor or a air conditioning vent? I'll let you know my suggestions if your able to cut or have a hole in the floor.

Yes i can cut a hole in the floor and then run it under the house. What do you cut the hole in the floor with? If you could just let me know anything on how to do it. Also what kind of filters do i need to be using to kill smell?

Thanks alot

You can use a sawzall or a core bit in a drill,or even a drill with a small bit in in it.Just trace the size hole ya want.I'd do a 4 inch! You are gonna need 2 of them.Then just drill them out.One for the intake and 1 for the exhaust.Use the silver dryer flex hose for the both.The white will let light in and out from your room.Put a fan above your light,and run the flex down to one of the holes along the inside of your closet in the corner maybe,and down through the floor.Take another small peice of the flex and put it in the other hole and just let it hang there.Tape it so it won't fall through.That is your fresh air intake.The fan abovewill pull most of the smell out of the closet and under the house.Let me know how ya do! I'll get cha goin! You can upgrade as you get the jest of it all!Grow on!

I have a little change in plans, i am now goin to build a outdoor grow box instead. Should I do the vin. system the same way?

Well now you have comprimised everything!You were going to do it in a controlled environment.You are gonna need some kind of heat and air conditioning.Are you gonna do it in a storage building or a garage,or what?

I am putting it in a wooden box that is 3 by 4 and is 4 foot tall. That box will be under a open shed. I am goin to have 4 plants with 400 watt lights.

There are 2 things that I would be most concerned about! One being what if it's discovered? Two being,you live in the states as I do.It's winter time.You would have to run your light at night to keep them warm.The plants are gonna outgrow the floor space,so a heater in there is out of the question.There are some other ways to heat the box.It consists of using your central heat and air system in your home.If the box is near the house? don't know! Is it?
