600 HPS Cool Tube Grow Light System
haha im aware of that
god id love to live in a blimp hanger on a side note...
i can vent the space whenever i want, and co2 would be constantly pumped in...but for the most part it would stay more or less sealed, aside from whatever way i find to insert the 2 duct tubes into the room...
which im not really sure how to do yet. there is a small 1x1 opening hinge door at the bottom of it and ill run them both through there....but i have no idea how to fill in the space between the duct tubes since theyll be in a square opening.
i ussually flood the op with a fan using that square hole but since ill be putting 2 duct tubes there that will pretty much take up the space ill have to find a new way to exaust..

Croim - what is your "grow room"? A room? A cabinet?
Here's a DIY on a cabinet I just built. Maybe you can get some ventilation ideas from there.
BTW - two 6" ducts won't fit through a 1'x1' square hole. If you're using 4" duct, use a hole saw and cut two 4" holes in a 1'x1' piece of plywood then seal with silicon.

1x1- feet?
OK, let me see if i have this right...
You want to use a closed-path cooltube, drawing air from outside to cool the lamp and then dumping it outside the op airmass.
You're supplying CO2 in hope of not having to draw air in for the op- right?
Where is your transpired moisture going?
Is there no ventilation path for the op airmass?
Am I missing something here?

pharmacan-your cabinet is amazing, i wish i had seen that thread a few hours ago, some great pictures there. it definitely gives me some vent ideas... had no idea i was talking with a professional builder...jeez.
mine is a closet with an access panel to the attic in the ceiling that is currently sealed shut, but i could mount a squirrel cage fan onto it i guess and use that as an exhaust. which would go perfect with
"use a hole saw and cut two 4" holes in a 1'x1' piece of plywood then seal with silicon". then it could be completely light and mostly air sealed...great!
btw-that story you told your neighbor is brilliant, and if i were him id probably believe that mylar was anti-microwave film if you started going into tech specs :error:
al b fuct-
"You're supplying CO2 in hope of not having to draw air in for the op- right? " no im using co2 for increased yields.
"Where is your transpired moisture going? " i exhaust it with a strong fan, so out of the op and into my room. if i answered that wrong please clarify
"Is there no ventilation path for the op airmass?"
as per the hydrofarm instructions i clear the room out every 3 hours, and run co2 with it sealed the rest of the time.
1x1 feet is just the small access door i made at the bottom of the closet door, it is not the actual size of my growspace lol
what am i doing wrong here?
your correct when you say i want a closed path cooltube drawing air from outside op and dumping it back outside. the ventilation path for the op airmass would be the every 3 hour exhaust cycle with the strong fan.
from your questions it sounds like im doing something very very wrong here
what is it?

criom - Yeah, I'm a noob a growing but an ace at construction. I just took my first clones today and I'm hoping all goes well with them. I followed Al's cloning instructions to the "T", so if the clones fail at least I have someone to blame it on. LOL
Anyway, as you can see all that vent stuff takes up quite a bit of space and I don't have your intake duct.
How big is your closet? Are you running your cool tube vertically or horizontal?
Have you seen this thread - The sealed room 3 lbs. per light you might get some vent ideas from there.

haha good backup plan on blaming Al im sure thatll go well :O
they look great to me, although huge!
yea i was amazed at how much work and design goes into wiring the venting ducts and such...but that home made carbon filter you have is so slick, looks store bought.
the closet is 3 wide 2 deep and 7 high, although i have another 3x3x7 space too. at this point though im thinking of just converting my entire 10x12 bedroom and sleeping in a big carbon filter
im not sure how im going to run the cool tube yet. since everyone says the reflector sucks maybe i should go vertical?
god this 3lbs/light thread is insane....what is it 14 1k lights? if he can figure out how to keep that cool i should be able to learn and handle 1 bulb hehe thx for pointing this out
i wanna see your cab in action though during flowering, be sure to bring your neighbor over to show him the servers
just tell him Dell went all organic

So, what happens to the temps and particularly the humidity in the room over the 3 hours that no air is moving through it?

That's just a vegging cab. By the time the clones are vegged I will have built a 10' x 10' flowering room. I'm growing mmj (medical) for my sis and I and the number of plants I can have is limited - but the size of the plants isn't. So I'm leaning towards larger plants.
Al's instructions said to take big clones so that's what I did. If this comes down to the blame game, I'm not leaving him any outs. LOL
That's one hefty filter. I had to buy real thunder-thigh tights to get around the eight inches. But it only cost about $25 - I already had the wire so maybe $30 - but hell I saw the same thing online for $250.
I'm going to see if I can find a thread about a guy's verticle cool tube grow. He had about the same size op as yours and his results were damn fine. Ya know, when see a thread on this board that you think has good info that you might want to refer to later, it's a good idea to make some comment on the thread, even if just "way cool", then you can find the thread again by searching your own name.

the humidity stays at 45% (i dont know why) and the temps rise to about 90-100, it has one small fan circulating air...comparable to a large computer fan.
the temp is the main reason im getting the cooltube, that and i want more lumens so the co2 is better used.
ive done one run with it and seen a 30-40% increase, so it seems like i could really pull alot if i had that last lumen/temp golden number dialed into my space.
what should the temp/humidity be at in your book?
i imagine if i put the tube in the temps would at least drop to 85F or less, and thats perfect. hopefully...

According to those much wiser than me, temps in the 90's are just fine if you are using co2. As far as humidity goes, one needs a dehumidifier in a sealed room.
...but criom loves buying equipment so that will surely come as good news to him.:D
