what's wrong with my setup, it won't reduce temps!!

[bostrom155]

Get a window A/C for the bedroom, and keep the closet door open, that room will always be cold, just the way it is, nice to sleep in, in the summer, but cold as hell in the winter. Portables are very expensive, save the money and get a nice window uint made for the size of your room or a little bigger. Measure the square footage of your bedroom and your closet.

Your darkroom louvers are your passive intakes. 8x8 = 64 square inches, your exhaust is a 4'' 170cfm intake fan. 4'' is 12.5 or so square inches.

well that means I have more than enough passive intakes since I was searching and reading and somebody said that your passive intakes should be 3.3x the exaust. hopefully it won't create a problem with odor, although people say that those intakes create a negative pressure environment so odor shouldn't escape.

I don't know about the AC thing, it's probably expensive and it might look a little suspicious having a window AC unit here, I live in an apartment and nobody here has an AC window unit, do they reduce electricity costs? if so, then it wouldn't be as suspicious. do all apartments allow ac units? I don't know if I should ask my complex or not they might want to know why since I have central AC.

I live in an apt as well, as told my landlord, i need my bedroom cold, so to not run my ac thru the apt, i run my window unit, and other ac as needed during summer.

 

[bostrom155]

200 bucks cans do the job, that's some of the fan money, and cheaper than a portable.

problem with keeping it on the window is that, my closet is right infront of the window which means if I have an AC vent on the window I have to raise the blinds, and there are 2 windows right next to each other which is a total of 70" in length. I don't want anybody to see the cab, or see me go inside the cab. I also need a better temp. guage I have the one the person posted in the first page of this post and it reads temps. higher than another temp. guage that he has. is there anyway you can tell if a plant is in an environtment where temps. are too high?

and does a window AC unit help in electriciy costs, or is it the same?

I'd prefer to have an AC unit not just for the grow but for myself as well, I'm in the south and it gets hot here in the summer, and I'm not a person that likes heat at all, I prefer to stay cold, I keep my AC around 75 and it still isn't cool enough. sometimes I just stand by the AC vent just to cool off.

is it ok to speak to the apt. complex people about this and make sure it's ok, before I get one of these

In another post you said it was hot enough in the closet to make you sweat. I'd say temps are too high.

Running more smaller AC's is generally less effecient than running one big one. Unless you cool one room seperately or something.

yeah, i'm also kinda big so I get hot quick, i meant is there anyway to tell from the plant? do leaves start to droop, or change colors, anything?

Yes,passive intake/active exhuast along with the proper sized intakes and fan will cuase a negative pressure environment.It keeps odors from getting out but only when the fan is on/running,if you turn the fan off odors can leak out the passive intakes or any unsealed cracks in a growbox.Also humidity (RH%) CAN CLIMB LIKE A BITCH WHEN THERE IS NO VENTILATION.This is why I advise running exhuast fans 24 hours a day 7 days a week non stop.

Small portable window A/C's are very cost efficient.A central Air /Central a/c unit uses thousands of watts and the colder you want your place the more work the a/c will have to do and the more elec you will use.


Try this.If your exhuast ducting is coming out of the top of your grow box in your closet,could you run a length of ducting to the closet door so it exhuasts into your bedroom?

My C13 sits in the open in my bedroom,it is lit by a A/C 400 watt HPS by the same 4" 170cfm inline that exhuasts the room.The fan is placed outside the cab and ontop.A section of ducting runs from the lights A/C reflector and up to the top of the cab connecting to the intake side of the exhuast fan.I don't have any ducting on the exhuast side of the fan.If you get notice of landlord/friends/neighbors/,aintanence crew coming over all you have to do is turn the grow off (turn off lights,fans etc) hide the poer cables,plug the passive intakes and voila,it just looks like a prefab closet!

The portable A/C seems the only way you can do it without routing your exhuast ducting to somewhere outside the closet the growbox sits in becuase no matter how large an exhuast fan you use,all that hot air is just going to recirculate between the closet and grow box.Like I said,if you could atleast connect it to a hole in your closet door so the air exhuasts into your bed room,you may be able to knock the temps down a degree or three.


You can try this too.

2 liter soda bottles,filled with water (tap,distilled...doesn't fucking matter,your not drinking it) and frozen.Freeze about 6-12 of them and place in your grow and see if that does anything but be sure to watch for humidity changes,don't want it going above 70%.

so if I was to add a window AC unit, would it be suspicious if not 1 person in my complex has a window unit, is this something I should discuss with the landord and let them know why, (I get too hot, and can't afford a high electiricy bill) - it really gets hot where I'm at.

and about dumping hot air into the bedroom how can I do that? I read your "400w hps bagseed grow diary" and I noticed we kinda have the same problem, but how can you dump hot air into your bedroom when you have your exaust fan connected directly to a carbon scrubber? do I need another vortex to exaust heat somewhere else?

I don't want to have anything outside the closet, since I'm in an apt. and you never know when they might have "preventive maintenace" or whatever

 

[Guest]

should I just get a C13 and put it in my bedroom?

Sure why not...if you could find one.

yeah I know what you mean I went to atlest 3-4 different home depots and lowes, and they didn't sell them anymore, finally found a home deopt that did and I broke it on the way to taking it to my car. damn thing is heavy.

Doesn't matter what you get,if you can't keep ambient temps what they need to be in order to keep the grow cool.

I can somewhat take better care of the situation just becuase my grow cab sits right in the middle of my room (fan noise actually helps me fall asleep better!) and the Central A/C duct is 2 feet infront of it so cool air blows down,gets sucked in through the passive intake and cools the cab slightly,but to run the central air all day would kill my wallet.I too was thinking of getting a small window A/C to cool my bedroom in the summer but I think I may just downfrade to a 250w HPS and make a flower and clone/mom section in my C13.

If you plan to by a Mills Pride prefab closet you should know that the C13 is no longer available.The new models are the C25 and C22 or something.The one that replaced the C13 has a slightly smaller footprint (18" Depth x 28" width) and the one that replaced the bigger one is also 18" depth and just under 4" long and about 6' tall.

Let me ask you anoher question.Is your central A/C unit housed in your closet?If it is you could get a C22 OR 25 (WHATEVER) and set it near your closet (you're going to need a spare closet door) and route your exhuast ducting to the closet where the central A/C unit will suck it up and cool it before pumping it back out your A/C vents.

If you go with the 18" deep x 3' wide c25 then go with a 250-400 watt HPS (400 only if ambient temps can be held in the proper range) and if you use the bigger model use a 400 watter to 600 watter (600 if you can really control ambient temps).

since this is a first grow I want to see if I can get a successful grow and then I'll upgrade to a different cab later when I learn the basics, so how can I exaust air into my bedroom my exaust is connected to a carbon scrubber

 

[bostrom155]

Dude, put some pics up, or did you figure it out? my electric bill doubled, but i'm not buying shit, so in the long run, it's still cheaper to grow, the shit is 100 an 8th around here.

LOL this thread is funny, and strangly similer to another thread.

What needs to be done has already been stated in this thread, If you cannot do this then give up, cause your plants are going to die.

This is part of preplanning a room, not just throwing something together and expecting it to work. It's taken me over 2 years to tweak my system to where it needs to be.

It wouldnt surprise me if your trying to grow some crazy strain like AK, or big bud(that you paid wayyy to much for). Guess what, your not going to yeild shit, if the enviroment isnt right.

Spend money on design of cab not on genetics. Once shit is good fly at er.

Hydro users must have temps proper to succeed. Soil has much more give, so if you cant get temps down to a resonable level, GO BACK TO SOIL.

Fuck man, apply same princibles used in any heat exchange system it will work.ie.Computers/cars/heating systems.

I changed my username and took me sometime to activate my account since they disabled registration. anyway, I finally figured it out, I didn't have to change anything, after all those tests with the light, scrubber, all I did was turn my cab around so the louvers vent is towards the direction of th doorway and brought it closer to the doorway.
It effected my temps. greatly, last night when I kept the windows open my temps were about 76-77 with the light on. In the day time it's about 83-85 with AC off and closet door closed. I'm also getting a portable AC so hopefully that should reduce temps. a few degrees so I can keep it at 76-77 with closet door closed. With the door open and AC on it lowers a couple degrees as well.
I've also bought Jorge Cervantes new book and dvd hopefully I'll be able to learn from that too.

The way I had it setup before ambient temps. weren't my problem, since I was doing some testing and my ambient temps were 76 and inside cab temps were 90, it was just turning the cab around so fresh air from the bedroom goes directly to the vent.

 

[fallenangel]

thank god

 

[bostrom155]

thank god

Glad you got it, now get to it. Get into your grow now, fuck the cab, its time to learn to grow soil, check out the forum. I think you need to KISS, just do the basics, can't remember what your nutes and soil is.
