Yaye you're back! Thanks for the fan suggestion, would this work for the veg side? Also would it be a good idea to get a Y splitter to connect the exhaust into one?
I actually considered getting two instead of one tent as well, but keeping everything in one tent just sounds so simple! The only problem I have with the smaller tent is it's height. Plants will grow no more than 4 feet and I'd much prefer to let it grow taller, since height isn't really the issue for me and I can spare some more space and money.
I originally was gonna spend $1600 on a superlocker, but thanks to the overwhelming disapproval, that is now my budget for my everything. You did bring out one of the biggest dilemma I had at first with HID and LED, but I resorted to just using LED simply because it will save electricity and less heat compared, also that way I can leave lights out of the way once and for all! I am going to do some more measurements around my apartment and see if I can do two tents instead. How much space would I need for a two tent setup? Or I could just get another 600w Mars for the 2-in-1?
I had the same problem in an older house -- heat rises to the second floor AND it's farther away from the central AC. What you really need is a duct boost fan, which will double the air being pumped to the second floor. You can buy them at any home store for under $30. They can be activated by a sail switch (which senses the flow of air and turns on the fan to boost the flow) or a solenoid that turns it on when the furnace fan fires up.
You can install a duct boost fan in a half hour. Trust me, it's worth it.
I just hook This up to the light then ducting out the tent. I don't use a filter but thats where you would put it.
Right now I have a PVC/Mylar setup with a box fan mounted inside to suck out.
But I need something I can paint IN inside of the booth with a sucker going out.
That exhaust booth looks good, I just did t know if it had enough to suck it all out.
I was looking at something like:
VenTech VT DF-6 DF6 Duct Fan, 240 CFM, 6" [link]
Because I already haven the duct set up.
i just go with the smell, i live rural though, the booster fan is a great way to move a lot of air but its kinda loud.
I have before. You need to get a another spectrum of lights($20). My first grow was T5 then the lamp died, it was a off brand. Then a 600w light and now the SUN. This winter I want to ditch the 600w and get some mars II led lights.
For 1 plant I would go LED or T5 and SCROG the plant. Those lights will run cooler and you wont have as much temp problems like you would with a hps. Unless you have the $$ for a good ventilation system. With the LED or T5 you still need a exhaust fan but you can get away with buying a cheaper one like this.
You can adjust some dampers in the basement, but that could mess up your balance. You can also install inline duct blowers ([link])
2x [link] : One on bottom for intake, one on top for exhaust.
2x [link] : This MAY be a little too much. There have been a few times where I thought I was getting light burn symptoms, but I just kept moving the light closer to the top of the tent (an inch or two off the roof now)
Other than that its FoxFarms Ocean Forest soil and HyrdoOrganics nutrients. I got the whole line but don't necessarily follow their schedule, I just use things as deficiencies pop up.
I have gotten that red streak in most of the grows I have done. I think is high in phosphate? It's been a while since I have read much into it but I believe as long as the whole stem isn't red, things should be fine. I know the plant turning purple is genetic, but it also depends on temperatures. My tent gets a little cool at night so that may have something to do with it too?
Could you just use a duct fan? [link]
If you can vent out of the room, I think the HID is a great choice. I use that exact hood in my 2x4, with a 400w dimmable. There's plenty of room for light and plants. You will need to ScrOG or LST, but I'd recommend that anyway.
How to duct the CoolTube: Run ducting from one of the side opening in your tent, to the hood, out the other side of the hood, to another side opening. So it is completely isolated from the inside of your tent. Get a 6' duct fan and to continually push air over the light. Again. . .air from outside, cools light, straight back outside.
It's a confusing thing to put into text. And people do set things up in different ways. I like this method best. This thread discusses it. I didn't really read the content, but the first picture the OP drew shows what I'm talking about.
Keeping your CoolTube on it's own circuit takes away the majority of it's heat. Connect your inline fan to a temperature controller, and tell it to only kick on when the tent hits 80F degrees. Tell it to stop running at 75. That way you are only running your fans when you need to (duct fan for hood runs whenever the light is on though!)--keeping the tent temp stable and allowing humidity to build naturally.
If possible, vent both the heat from the hood, and tent, outside. Or expect your AC bill to go way up.
I'd suggest something like this duct fan...
In Line Duct Fan
I have that same size tent and use three Mars 300s and use this, [link]
ohh yeah. I bought this one that the guy above reccomended. and i got the speed controller also.
Someone asked how to mount this baby last week I think:
Apparently it's popular for homemade spray booths. As far as quiet, powerful, and cheap go: pick two :)
Wow for the LED, I will definitively look into LEDs if I decide to upgrade my old 400W HPS.
As for the fan, if it's anything like this type of duct fan, it won't work with the filter.
This is the kind of fan you need
With a tent that size you could put a 400w HPS and get great results. You will need ample cooling and a Inline fan like THIS. I would suggest a hood for the light. Something like THIS will do pretty good since you can switch from MH to HPS. Maybe not these exact brands but something comparable.

Sorry to keep bugging ya but something like this?
Warning, I don't know what Im talking about, but this is what I have in mind for a similar setup!!! I think exhaust will end up being your friend more than intake. And moving the air around in the GH. 6" inline fan... I can get one like this for free so Ill try it out.
They sell reducers so you can run 3" dryer exhaust, like the plastic/nylon exhaust, reusable zip ties. Cut it to size and use some insulation board to put it out your window. Of course it needs to be sealed around the exhaust and around the window sill to keep water/weather/spores out. Also, you would need a vent cover... something like this?
I said to use the reuseable zipties so you can put patches of window screening to help keep the spores from clogging your fan... not sure if its an issue, but Im going to try it out.
All of this means you might need more humidity too.
If your GH is too airtight you will definitely need to get some intake holes at the top, and the exhaust goes at the bottom. Also, dont worry too much about con tams at that stage.
Once again, this is my take on the GH your looking at... I don't have experience to back this up.
These work amazingly well for me, and also they fit perfectly into the holes on my tent. They're a bit powerful though, so you would need a controller to dial it back.
Something like this might get you more oomph:
Adjust fan speed until your temperature/humidity normalize as required.
