Temperatures and Light Sealing

[getnasty]

Hot air does rise but if there is suction nearby it will be drawn towards it.

The way i see it is if your fan was strong enough it should at least tighten up that ducting a little when the fan is on.

To block light coming through the intake holes you can use a piece of cardboard cut into a shape that makes it slant off the door, the paint inside matt black and stick it over the wholes. This way light wont get in through there.

I would still move your output hole higher and get a better fan. That should solve your problems straight away.

The exhaust outlet has to stay where it's at so it can be covered. After I move the fan/filter, I'll take a reading and see about getting another fan, if my temperature's aren't better. Also, the fan does tighten up the ducting when it is on. I put an excessive amount there so that when I open the door, it doesn't interfere with anything. I can take a few feet off after I move the fan/filter.

Modified it a little bit. The towels are there for padding to keep vibrations from being so loud until I can replace the fan with a 6", if need be. The temperature read 87 degrees with the door open. That's with the heat on at 70 degrees already, and the window shut. The window is open, the heat vent is covered, and the door to the closet is shut. In the morning we'll see what the temperatures are running. The healthy plant doesn't seem to mind the heat right now. I'm working with my partner to try to come up with the $225 to purchase the light I linked earlier. We'll see how that goes. As for the fan, I'm going to try to replace it through HTG with the 6" model, for an additional 20$.

You need to get your ducting so that it does not dip and hang like that. I also agree that your intake and your exhaust need to be a lot further away from each other--you are most likely just recircing stale air.

I'm still confused on the vent holes--a 2.5" hole is 4.9 sq inches. A 4" hole is 12.56 sq inches. How many 2.5 holes do you have for intake and how many for exhaust? If your 4" fan and ducting is using a 2.5" hole, you are restricting the area of the exhaust a huge amount with a 2.5" circle.

He has a pic in post 3 thg that shows it.

The temperatures are idling at around 85, peaking at 87. Friday, I'm going send the 4" back and have them ship the 6" off. It's $40 after shipping. Plus I have to send theirs back. But I'll atleast I'll have something adequate. And I can run the old 4" that I managed to get working again until the 6" one comes in. Next up will be the Mh/HPS dimmable ballast/air cooled hood. After that I'm done spending money. Lol.

I'm not sure what to do with the ducting, really. I've already cut 2 feet off of it. I need to be able to open the door. Exhausting out of the door is the only option I have for exhaust. And the exhaust has to be covered. Putting it up top and putting a poster over it is a no-go. The fan blows too hard for a poster to stay in place, and to boot, a poster blowing away from the door is a dead give away. I really have it set up the only way I can have it set up. Any suggestions appreciated.

Do you have people walking into this room area of the house often?

 

[getnasty]

No. But it is across from the window on the other side of the room, which the driveway from the behind the set of triplexes passes by. The only person I need to hide it from is my landlord, who very rarely visits, anyways.

 

[Jericho]

Well then why not put the out take hole at the top and only put a poster over it when he visits. If he is inspecting the place I doubt you will leave the lights and fan running.

When I had two carpenters/plumbers at my beck and call, I had the best most dialed in growrooms ever. The bloom room was in an attic, so we'd run ducting from the bottom of the house (outside) all the way up through the house through the wall up to the bloom room where it blew across the girls. Then on the outtake we'd have an inline ozone generator and blow out through the eves. Couldn't give you specs or anything but I know you can't have the intake and exhaust together like that, then again I'm more of a gardener then a carpenter...

I guess I'm not understanding why. I know the closet isn't pulling in hot air from the exhaust. I feel the air from the exhaust where I'm sitting all the way on the other side of the room and it is room temperature. Inside the closet is not room temperature. That, I also do not understand. Perhaps it's just not adequate airflow? The air is cooling before it gets out of the door? Idk. What I do know is that the air outside of the closet door is not hot. Soon, it will be cold, as I just put my air conditioner in the window early... I opened the door to check temps and saw it at 90 degrees again. We still have the heat on even though it's nice out today, so it's making things run a little warmer. The a/c being in the window now will keep the room cool, and probably the closet too. Either way, by next week I'll have the new fan, and by the time I have to flower, I'll have the new a/c hood and ballast.

dude, you're talking to someone who opens the bloom room when the lights are on to vent and close them when it's time to go to work (coincidentally when the lights go off) I know it's not right but I do what I gotta do and my carpenter/plumber friends have long since moved on and I am not physically able to do all that work anymore. I just know that air under a house is very cool and there is no possibility of air recirculation i.e. stale hot air...thn again if you're getting cool air, is it "freshly exchanged" w/ enough co2?

p.s. Wowzers! Total run-on sentence action goin' on there...lol.

It's in my living space, so I believe I am, as I've been led to believe so by these forums. Lol. As I understand it, there is an adequate supply of carbon dioxide due to it being in the closet in my bedroom, of which I am always inside when at home. So I think my co2 exchange should be adequate. Though I've been considering a DIY CO2 "system" -- tube with holes, yeast, water -- for shizzingigs.

right on right on:aok: if you're getting sweet cannabis outta it, then all I can say is what an old backwoods grow guru told me once: "Don't sweat the petty....Just pet the sweaty." *ding*

We'll see how it turns out This is my first grow, using information from these forums primarily. Some of it I seem to have jumbled up, but as I bumble about, I'm getting things in check and ironed out. Check out the ole grow journal if you haven't yet, and thanks for stopping by to help.

The co2 that you exhale is no where near enough. What you are doing will work. You will grow plants and they will bud and you will smoke it and get high. What we are advising will mean you have bigger better buds that last longer and get you higher hehe.

I just dont think any one wants to see you waste money using an ac unit when you could just move the hole. JMO of course. Hope it works out ok.

 

[getnasty]

The a/c unit is in the window regardless. I'm just putting it in a month early. Not a big deal. And what I'm trying to achieve is those bigger better buds that last longer and get you higher. That's why I'm trying to get this dialed in correctly, but in order to do so, it looks like the a/c hood is going to be a requirement come flowering time.

One thing to consider as well, is that if I do move the exhaust hole up to the top of the door, I'll need to move the fan back up there too, and won't be able to pull heat away from the hood I currently have. Not to mention, I'm really not comfortable with moving it up there in the first place. Even with the poster over it. I'm just not seeing the exhaust being where it's at as being an issue. I truly do not think it's pulling hot air into the space as I can feel the exhaust blowing on me from all the way across the room, and even up close, the air it's extracting does not feel warm. Maybe with the 6" this will be different? I don't know. What I do know is that I'm going to continue to monitor the temperatures. Having the fan/filter off when he is here is a definite no-no, primarily when it comes to flowering. The scent will bombard him inside my room. I think the temps will lower to the low 80's with the air conditioner being on. Add the 6" fan in a week, and I could probably turn the a/c off until summer. We'll see. Either way, by the end of april, I'll have a new air-cooled hood in there. Thanks for all of the input guys! And any information to come appreciated all the same.
