Club 600

yeah basically hat's exactly right. I'm thinking a portable AC unit for the room around the tent. but they are prcey, and don't they then in turn have to vent the hot air out like a fride etc?

i'll try and explain better

Room> tent >filter>duct>cooltube> duct> fan (sucking)> Duct> out though airbrick


Thanks doobie!

Yeah, portables have to be vented out a window adapter, otherwise all the hot air stays in the room.
With a 6" hose, you need 28-sq. in. of inlet from a window.
If you have a window that's 24" across, you only need to open it, say 1.25" to have a perfect opening.
Make a cardboard box of the same size as the small window opening, making sure that sticks out just far enough from the window frame so that you can connect a 6" hose to a hole cut into the top or bottom surface (or even a 4" or 5" hose & hole), and then run that duct to one of the tent's inlets.
A small & thin ducted window insert will hardly be noticeable compared to a window insert with a 6" circular opening in it.
Paint it black on the inside, and it's pretty stealth.
If the tent's inlets are blocked/closed, cool air will be drawn in from the window through the auxiliary duct, without totally freezing you out in the room.
This would allow you time to save for a portable A/C unit for when summer arrives.

I was going to suggest the very same thing Doobie, lol. You can pick up ducting extensions at B&Q (well you can at my local DIY) that have a 6inch attachment that opens out into a triangular shape with a rectangular shaped opening, just like you said, only an inch and a bit wide, but about 2 foot long They are not that pricey, and knowing the amount of rain in the North of the UK then probably better getting plastic.

Some pics from today. Blue Pits finally swelling up and hoipefully now on the finishing straight (some are ahead of others...)

Some DOG clones i just potted up and getting the MH veg training on.


...fuk me this is a shaggable plant. Blue Pit baby.









really liking these Blu Pits, they seem to have picked up characteristics of both parents nicely.

downstairs in the flower cab.


Peace, DST

basically what I've decided to do fella! Though I'm weighing up whether to run the lights on totally different loop and exhaust back out. either way i think it would need at least a 4" fan.

what size do you guys use to push through lights? whats needed? I was thinking 4" or 5" tops

think i know what you meanI'm going to have a ook at fantronix.com they have boatloads of stuff like that.




hopefully though the upping to 6" duct for the outlet will reduce it a degree or two lol....

cheers lads!

Any other ones?

Doing Dog, myself. As I seen pics of big yielding Dog plants outside (monsters!). I think jig posted them. So that got my vote

I'm running a 435cfm 6" fan for a single 600w and I can get the plants about 5 inches from the glass without heat stress (light stress is a problem). Oh, and it draws it's air from the room, not a window insert, and the warm air gets exhausted out the window. I only do this because of horrible condensation and water drippings off of the cold inlet hose during the winter. Summer it's fine for re-attaching to the window outlet.
I bought the 6" with the intent of adding a large carbon filter to it if we move to an apartment on the ground floor.
For cool air into the grow space, I have a 265cfm squirrel cage fan, attached to a thermostatic fan controller, and ducted through 4" hose.
And when it's really hot I disconnect the cool night air from the window and pump in cold air from the A/C unit through a 3" flex hose.
Not sure if any of that info will help, seeing as you'll be cooling 1200w.
One of the others will have more experience with controlling heat from multiple lights, I'm strictly bush league.

Good morning crew.

Okay I took some pics, but my camera, is not focused right!DAMN KID!!!!!!!!!!!!!!!!!! So I just took a few sorry pics. To stone to fuck with the camera right now, as I don't know the camera would have to take some very strong thinking power. And at 4 am in the morning-- I'm cool with that.

veg, I shoot a pic of my burnt tips from my t5ho setup. my closet is just a sea of green.

Had a long day yesterday and Still got stuff to do today, but will try to put time in to my grow journal/
600w thread to night. All fuck it's Friday!!!!!!!!!!!!!!!!!!

Just to say something different, because that's what I do! If I gather correctly you are venting 2 tents with a single 6" fan. Ill say take the filters out of the tents, and run a single filter on the outside of the tents with the fan pushing air through the filter. It would shorten the ducting in both tents, and increase the airflow (I believe) cuz ur using one filter. Filters are rated for cfm so 1 filter should work for both tents, just not last as long. Tomato tomato? Lol that's my early morning take on it anyways.

oh I don't know if your intake are passive too but you could work on increasing that with some fans. On my first tent I ended up cutting the flaps off one of the vents cuz they didn't flow well.

My thought is that your filter is way up high, so it's having hot air pulled through it, so it's not able to cool the lights and it's just a bunch of hot air being circulated while all the cool air is on the floor of the room.

Also, those turns from the filter/ fan to the cooltubes look mighty tight. Maybe just turn the cooltube apparatus so it's going diagonal across the tent, leaves more room in the corners for the turns to open up a little.

There's my 2p.

I'm in the planning stage of adding an AC to my room as well. I've seen some units that have 2 hoses, one in and one out. Those types take no air from the room being cooled and probably the type I need. If I go with the single hose system, those exhaust some of the (stinky) air from the room and now I gotta figure out how to duct that into my exhaust which wouldn't work in the current state because my filter is first. I'd have to relocate my filter outside the room and push everything through it. I haven't seen a lot of 2 hose systems, but I haven't looked very hard either. I got a few months and money to make before I get there.

Yeah, I wish I'd known about the dual-hose units back when I bought ours.


Here's a groovy 3-hoser unit from The Great White North:

Some of my cookies. 1 to 10 I give it a 8. Fat yielded for me, great flaver, and smell like some sugar cookies to me. Taste is very different from others stains I have grown, very sweet.Looks, are crazy. Love the looks for this bud.

IPHONE/SMART PHONE USERS!!

Let's do a cool comparison of sorts ok? Open up your App Store and search for decibel meter. I'm on an iPhone and I loaded the first 4 free ones. They were all identical in their readings. Whether or not they are accurate DB readings isn't relevant if we're all using the same stuff. I can't speak for the android versions as I don't have one here right now to do it on as well and compare, but later I will.

To keep things similar, make sure you don't aim your microphone into an actual air stream as this also raises the level. I'm just looking for a general reading. Mine was taken in roughly the center of my room and although I moved it to within 2 feet of my fan, it didn't increase (again, not in the air flow)

My initial purpose is to see what other people are dealing with. Because I think my fan is too loud and want to get a baseline.

So if you want to join, please do! Also state whether you're using an android or iPhone device and also what type of exhaust you're running. Lets do this!

Ok I'm running a generic 6" fan and tested with an iPhone 5, my DB rating was from 80-82.

I will do android version sound meter give me a minute

A few places give you db ratings..
Just the first link I clicked

http://www.greenspirit-hydroponics.com/4-inch-rvk

Although never bothered testing them.

will check it out when home.

My meter says in middle of room (2diffrent meters) first one says 96 second 95 in my resivor and and nutrient room where my dehumidifier and fan are and ballast fans says can't read on both Well goes to the max and stays there
I where beats audio headphones and can still hear my room

My exhaust runs carbon filter at top of room for hot air and then thru 2 hoods then a fan then exhaust out

I guess you doing dwc? I've down 3 different things. First was put a water pump in the bottom of the rez, and I'd plug it in when it wanted things drained. But that only works with a single rez. When I had separate buckets I put level gauges, or tubes from the bottom with a 90 joint and a tube going up the side. To drain I would just tip the tube over to let water out. Another time I just made separate tubes sticking out with shut off valves at the end, drain it like that.

Or you could just never change the water.

EDIT:

about 1:00 you can see what I mean

Jig, bro! Your a fukn inspiration bro!! I woke up this morning just not in the mood to start yet another project with the girls (just finished hole new room 2 days ago) and was about to call it. Then I come on RIU and check my 6ers and there's Jig with his amazing shit that makes my jaw drop and out comes the bowl and tools cause I'm ready to build me some scrog baby!!!

Im not sure if it should start right on them or a little up so they grow in to the scrog...??? I guess I'll put something together first and do more research on that part once I have it built.
@DB it's all good. I feel like I'm in the dark with no flashlight when it comes to scrog but that won't be for long! Hopefully they'll be some scrogging within the hour. I'm sure something will happen to delay that hour tho lol.
