Thanks guys -- Hammy, I know you have the same tent as me -- I have been reading through the grow room threads (for hours) looking for tents, and have learned a lot. The thread you have provided will be the nuts. I believe I'm going to have to cut a hole in the side of the boat to do this right. To put an exterior vent and a carbon filter -- or I could just filter it into the boat and eliminate a heater maybe -- probably best that way. I will go read some more before I ask any more dumb questions 
Thanks
ThanksOkay, I have read through every thread of the tent growers club. I have a much better understanding now than before, but.... I see setups with the inline fan attached right to the cooltube -- I figure they must be pushing air through the light because there would be a LOT of heat in that fan if it were sucking. I think sucking the air out is the way to go to create negative pressure. And, wouldn't it be better to suck the air theough the cooltube from the bottom of the tent? I see a lot of people with the ducting going from the top on one side to the top on the other side -- and then a different fan for tent vent? I'm still a little confused here, but I have a much better idea now. --
Passive, cool air in from the vents at the bottom of the tent. Hot air sucked out of the light and out the top of the tent. A vortex fan sucking the air out the top and through a carbon filter. Okay, that I can do. I just need to order the fan and filter and a speed controler, another timer, and what else?

On another note -- my little plants are growing out not up. I have decided to cut the light back a few hours a day and see if I can't get them to stretch some. What do you think? If I'm running the lights 18/6 do I need to worry about light hitting the plants during the six hours of dark time?
No you don't want to push the air....actually the air is not that hot and it wont damage the fan. Pulling the air will give you negative pressure in your tent. That is a great thing because it helps control odor issues tremendously...this is how I hve mine set up.
I don't normally run a carbon filter because like I said the negative pressure along with the fact that I vent the air out a window leaves me with no odor.
With a filter I wld run it like this.
Inside the tent I hang my fan in the top left corner where the hole in the tent is then I run ducting from the fan to the cool tube then ducting to the filter.
Outside the tent I hve ducting from the fan running to a window where it gets vented out. It is a second story window so the odor is not a problem. The fan pulls the air from the tent through the filter through the cool tube through the fan and out the window. Hope that makes sense. I can take a pic and post nit for you.

Okay, I'm getting it now -- one fan should do it all then. I had the 160 CFM inline fan just hanging in the top of the tent duct taped to those little string thingys on the vent tube. It was awful looking, so I hung it from the top of the tent and stuck it in the vent hole, and it looks and works a lot better now. I know 160CFM is not enough, and I will get another fan that pulls at least 400 CFM and switch them out. Perhaps I'll place the bigger one outside the tent so I can run the cord across the room to the other 30amp breaker -- way too many wires and plugs here -- and more to come....
I guess if I'm vedging I don't have to worry about ambient light getting to the plants.

Hi Hemper ... I think you can remove the right duct from the light and if you attach the extractor fan on the left duct outside the tent it is ok. You just need then to remove the hot air that the extractor output outside the boat/room. If you have carbon filter you should attach it to the right side of the light inside the tent.
Doing this and closing the tent windows you will have negative pressure. If you have any hole on the bottom put a duct also so you can have some passive intake.
Hope that helps. :aok:
Looking nice

I am a little confused....Do you have a fan connected to the light ducting?

Wait, i was just kidding around, but then i thought about what i had seen. "Does that duct come in, then to light, and then back outside??" i thought. Where is the air coming from?? One end HAS to be open inside the tent. Ok , if that fan is sucking air from inside(tent) to outside(outside) then why is there duct after the cooltube?? That is where your air is being drawn FROM and pumped outside. I dont understand why there is duct after the cooltube unless it lead to a filter, but yours is going right out the other side. Why? Does it loop back to the lower vent on that side and back in? Where is your exhaust point inside the tent? Do you know what i mean? I'll watch for your post and maybe i can help.
Yes, I am sucking air from outside the tent on the right. I will take the inlet off the right side and run it down into the tent where there is cool air. I almost have it, and thanks for the laugh Solanero. That's Bubba Cush. He just supervises and then laughs at me when I screw up, but he is a great friend of mine.
Yes, THG, there is a fan on the left side of the tent sucking air out. I will put a filter on the intake when it comes, and if I need a bigger fan I will get one -- I WILL make this operation successful

I measured back there (again) and if I move the toster oven out of my grow room I'll have room for a 4-bulb T5 fixture, and that my friends is the missing link in this setup. I'm pleased with how it is coming along. I even have a comfortable place to sit and watch them grow. I'm stoked.
