As you can see it's going to be pretty cramped in there, and the proportions aren't right because I don't have the measurements of the equipment but it gives a good idea of the proportions and my tentative plan.

What I am interested in is the airflow. As you can see I will be using a small passive intake (window) to pull the air from, through the filter, cooltubes and then finally out of the room and into the living room which will be unheated and rather cold (especially now in the winter).

And that's another issue, if it's freezing cold outside and the lights are off I'd think even the slightest exhaust of air would put that room into freeze mode. The possibilities that I see are that either I crack the window open just a little and have the exhaust on the lowest setting to keep the passive intake from turning into a stink gateway...

Or I blast the heat in the room and let the speed controller with attached thermometer do the job of balancing it out through the exhaust; leaving the window open. Any Ideas?


I could have the black box that I put on the window with two holes, HoleA for straight exhaust through the lights without a filter and out the door.

HoleB would have ducting running low into the room to cool it and deliver CO2. I then have another blower at the door with a carbon filter directly before it.

Would I have â??thermometer speed controllersâ?ť (haha, whatâ??s the word for this?) on both of them or just one? How does the CFM scale down. Could I use just one powerful exhaust? I'd be interested to hear if you think this will be an unnecessarily complicated idea.

Open to whatever but I can't touch the ceiling (wonâ??t be able to repair it) and the walls are drywall, pretty unsafe to hang something heavy on but you know, I don't have any experience with that so I don't know the load it can take or how to distribute it and so forth so Iâ??m going for a support grid made out of PVC pipes (someone suggested a tent, though I donâ??t see the benefitsâ?¦ maybe there are some, please advise).

Thank you, I really appreciate it.
what bulbs and reflectors you gonna use?
how many plants you wanna grow?
and if you wanna but the heater with thermometer MAKE SURE IT ISNT DRY HEAT...like fan heaters,cos they can damage plants baddly,and what hight is your seeling?
