looking good dude i like your setup it is actually the type of setup i would like to end up with sonner or later very solid work dude keep it up

 

[Mampi]

VERY.... fuckin sweet my myan.... just a lil Q about the way you have your lights ducted.... I guess all is well because the buds look FAT and sweeeet but I reckon that the heat is not being exhausted as effeciently as it would be if the lights were on 2 separate circuits or even better have there own individual duct, rather than them running from one to another.

just a thaught bro, although I can see yas got things under control there.

 

[THCV]

thanks coloradro and mampi!

mampi, you are definitely right, two separate duct pathways, each venting 2 lights, would be ideal. right now, the final light before the fan gets pretty damn hot, but it is aluminum and radiating into an ac'd room (with no ballasts!) so i am hoping it will be good. probably not great for bulb life, but creating another duct pathway would be a pretty huge hassle, as punching through the ceiling and walls is probably the messiest thing we do--and now we moved the plants into flower. I am switching to 10PM-10AM now (was off at 11:30AM last time) for the summer, and with the remote ballasts and vented lights i am hoping i can keep everything cool. if not, another duct will happen.

 

[THCV]

here's an idea: rather than having 2 parallel paths of ducting, how about if I add an intake fan to PUSH air into the duct, to allow the Fantech 8XL on the other end to PULL more easily? Think that would make that final light much cooler with less hassle, or is it pointless? feedback appreciated!

I just want to be clear and issue a WARNING about the Soleus LX-140. I have had it break down and require a total replacement 4 FUCKING TIMES. I live not far from the Soleus warehouse (by PURE chance) and so it takes me an hour to drive it there and get a replacement. But if I didn't live near them I would be FUCKED. Don't buy this model, get something else.

just posted this in my AC thread but I want everyone to be aware. The Soleus LX-140 is the dualhose portable AC you see in the pix above. Piece of shit; died at 2AM last night and temps went up to 90 for the rest of the "day"(not bad, actually, considering). Ugh.

 

[THCV]

one more thing: all this temp shit is SO MUCH easier to work out if you actually know the history of the temps in your rooms and outdoors. Lacrosse technology makes this awesome wireless weather "data logger" that stores 3000 data points of temp/rh every 5 minutes for the base and up to 3 remotes. It makes dialing in temp much more manageable. here it is, costs around $70 with one remote:



with this you can really nail when your lights should be off by, when they should come on, and when fans should turn on and off. plus you can really see the impact of your ac and its own on/off cycle, how it effects temp and sometimes even more importantly rh. an excellent tool.

Temps in the room being high, i now have a res with water temp of 82. I know i need to get it down, and i have a few ideas, but I just ordered a wireless water temp thermometer for my datacorder, so I can track water temps over the day and night and figure something out that doesn't invlove a chiller. I am thinking of bubbling cool air through the res at night to bring it down to lights off room temp and then turn the bubbler off when the lights go on. Think it'll work?

nice!

THCV: I have a a sealed box...could you eplain how the dual hose hooks up to your lights and/or ventilation system.....

I have a box 4'x8' 6'tall, 1000w x 2 in a 60" cool tube with a vortex pushing air thrught the cool tube and out.. so it basicaly cycles air from the outside of the room thru the cool tube...but now I need to ad A/C to controll the temps?? can you show me how to hook up with the dual hose and still have a sealed room? please

 

[THCV]

bandan, based on your diagram you can leave the existing ductwork alone---it's all good (although you should get your intake air for the lights from a cooler place, like the floor, not the attic).

Now, for the INTAKE of the portable AC, use air from the floor of the next room, or from the basement--wherever you can get the coolest air. Run a duct from there to your INTAKE. Then take out the EXHAUST duct out of the AC and run it into the attic, or out of the wall, high up (heat rises, making the work easier for the exhaust vent if it goes UP a duct). It will be a standalone set of ducts.

You can see it here. There are 3 visible ducts, the lowest is the AC INTAKE, right above that is the air-cooled hood ducting (totally separate, but both sucking air out of the floor of the next room), and then coming out of the AC into the ceiling/attic is the EXHAUST:





Makes sense?

THCV - your setup is "da bomb". nice strains too - love the purple MK

regarding the ventilation system - I think that adding an intake fan to cool the lights is definately the way to go in your case rather than redesigning the whole system and having 2 duct pathways. Its much simpler and more efficient in several ways. I agree that 2 duct pathways would be better but I think you will find that an intake fan will make the the duct flow much faster and both fans will be able to run with much less effort. I would recommend that the intake fan should be the same as the exhaust fan in order to avoid one being overpowered by the other.

I have an idea - why dont you buy an intake fan - try this idea and if it doesnt work out return the fan a couple of days later. (Of course make sure you can get a refund)

good luck

THVC: thanks for the quick reply...my box is in the garage so all the air will be comming from the garage...

im still kind of confused...both the tubes are the intake and exhaust of the cooling for the A/C... then the A/C used air in the room to cool and keeps it sealed?

 

[THCV]

ezra- thanks! temps have been under 80 in the room so it isn't urgent, but i may add the intake fan in the future. thanks for the recommendation, good points.

bandan- not sure what your question is. the dual hose AC keeps the room sealed, uses external intake to cool it's coils and external exhaust to exhaust the heat from the unit. It has a separate in/out for processing the air in the room, and in that way it keeps it sealed. if that doesn't answer your q, please rephrase it. peep this from my AC thread:

The only smelly air that is expelled is into the attic, and only when the air exhanger on the ac unit has switched to move indoor air out, like when heat or rh is very high; otherwise it is like a split a/c. I have no charcoal or anything, but i will put an ozone generator in the attic if i ever smell anything outside the room--which I haven't yet, and i take lots of walks around the house outside. This is my 3rd flower in the room with no serious problems; veg isn't sealed (why bother).

I'll put up some updated pix shortly for y'all.

 

[Guest]

perfect! thats what I thought I Just wanted to make sure thats what the dual hose was for.. to cool the machine itself not the air in the room...

oh and great idea about topping off the rez...im gonna get a dual hose unit with a drain so I can drain back into my rez outside.. thanks again!!

Hey THCV, nice grow and electric setup...you had to connect the extension cord to the power strip yourself or you custom made it or what?

so you have a 240outlet on a 30 amp circuit, and the extension cord plugs into the outlet then runs to the power strip you were holding in your hands and then your lights plug into that?

i reason i ask is because im going to be doing a similar setup with 3k and dont know too much about electrical, and i might need to run a cord like that.

When your a/c is running in the growroom it doesnt exhaust smelly air through it into the attic, b/c i was thinking of a portable a/c but im not sure if the intake it uses is from the actual air in the growroom

thanks

thanks, gsxxer. Yes i made the cord, used a super heavy duty 120V xt cord and cut the ends off; the key is using at least 10 gauge wire when you are running that much amperage. I got it at Home Depot. You got the signal flow right.

When your a/c is running in the growroom it doesnt exhaust smelly air through it into the attic, b/c i was thinking of a portable a/c but im not sure if the intake it uses is from the actual air in the growroom

see my quote above about this, i think i explained it clearly. also, see the AC thread. it's all about dual-hose units, single hose will exhaust smelly air.

just a quick note/warning: fuck MK Ultra. It has been the most finnicky plant, and my MKs are always the first to get any pests and the source of evil in my garden.

I found one of my MKs totally infested with mites yesterday. No TW or C99 has mites (yet) but 2 MKs do and the Bubba got a few. But the MK is always the source of my problems.

This is the last time I grow that strain. In fact, I am sending the mom outside to pasture in an outdoor grow; i no longer want the genetics of this plague of a plant that brought me Powdery Mildew, Mites and nute problems. Yeah, it has potent and pretty purple buds, but it sure isn't worth the grief, not when C99 and TW are free of problems.

 

[AbaZabba]

I hear that bro, c99 and TW are finer strains than the ultra in my head anywho, little picky ladies.
I still remorse of the day I lost my TW cuttings to see no more since Make sure to savor that TW alive and 'keep on keepin on'

 

[THCV]

AbaZabba, I can't wait for my TW. I actually have two COMPLETELY different cuts of it (Norcal and Arcata?). One is short and vine-like with very tight internode spacing, the other is tree like with wide spacing. But they are both supposedly the TW! The vine-like one is maturing at a blazing speed, buds are already covered in trichs at 20 days, but the tall cut has no trichs and looks like it will be at least twice as tall--and it only vegged for half as long! It will be interesting to see how they compare; i have heard they smoke and smell the same, although it is hard to believe considering how different they are.

Honestly, i could smoke TW only for the rest of my life and be happy. So 2 kinds of TW should be just fine. The vine-like one is weird, i gotta say, i have never seen pot grow like that.
