Exausting outside of grow room

[LeastExpectedGrower]

Intake screen was caked shut with dust. Louver on bedroom door has a small layer of dust on it so the air outside of my room is dusty too appearently. That sucks, I didnt realize I had a major quality issue but my last weed harvested was totally fine.

Will have to do something at some point, maybe not idk. I know I want the carpet gone but then I have to take everything down and out the room and back in but it sounds worth it. Im not a dirty person, Im lazy and the least clean but I keep up, my room mates are neat freaks. This is kind of embarrissing but its the house, its old.

There are a few ways to look at this...Sounds like your ventilation system is CRANKING, so you'd definitely be pulling a ton of junk through any filtering you have set up, and also creating quite a suction in the room, but is probably also making you add a ton of humidity to keep things on point environmentally. By contrast, I have my two ventilation fans set low (at 'rest' my exhaust is running at 3 out of 10 and my intake is 2 out of 10. If the heat triggers it to increase it notches up to 4/3 or if really hot it may hit 5/4 or so. My goal is to keep ventilation steady but also VPD and temperatures steady as well without that stuff cranking all day, so finding tipping point where there's airflow but stasis. I change my filter fabric when it gets visibly dirty, which is every grow or two depending on how long they go.

Also, I'm in a tent that's nearly identical (3'x5'x5.5').

I was told need to vacuum carpet every so often like twice a week minimally and I do not do that. I should start there. I just lived here for a while and trashed it so I quit keeping up on that amd recently decided to take out the carpet so it could be clean again.

Then I turned it to a grow room and so theres lots of surface area not vacuumed even if I did since tents are up and furniture so feels useless to vacuum that often. Shoot this is a pita of a issue but will update here as I figure it out but want to harvest a few runs first and strain hunt and mother up my favorites.

The fan and filter suggestion was cool, the diy fan on top of a box made of furnace filters, I will try that too. Maybe make new intake ports that are wider. Adding any real filter is a challenge as it reatricts too much air flow and so rh rises.

that’s pretty good advice for life . Not sure it’s that critical to your grow tent.

Whats the highest you pushed rh before and was fine? This is exploding and rh is 57-60% highs but goes to 50 and a little lower when I open doors so I opened another intake vent and lowered dehuey to 35%. But I think it will climb like a mug in flower if you have a lot of buds.

 

[medidedicated]

So freakin anxious but now excited, its 46% now. Ooof I never grew this big all the way to the end. idk what the heck is about to come out of it, a big big bag for my experience level. Or a disaster of mold again.

I am going to wait for it to enter mid flower just about and then prune two or more branches, the first nodes did not make it to canopy but left it to help with stretch, heard that helps.

Then will def and prune suckers, you know, clean up the leg area etc. Maybe apply some lst clips to expose some sites to extra light and flaten canopy, expose more light to sites that are just short of the canopy that wont be after bending said branches.

It is growing into the other canopy so I moved the other plant a little. It had another plant in there but was a herm or male so I tossed. Cannot wait to have a smoother routine going. So far these plants arent deficient in anything, coco is doing me well like I thought it did before until I let it dry out.

But anyways back to topic. Had a freak out moment.

Not knowing your living situation. Renting/own. House / apartment. I can tell you I run a 5 x 5, use an ac infinity 8 inch inline that goes up into my attic it is hooked up to my passive air vent on the roof. I run 700 wall watts. The 8 inch inline keeps my tent at a steady 80 lights on. I only have to run the inline on the 2nd setting.

Is this jam packed? Is 50rh ok if thats the lowest you can get it? Should I turn my dehuey to CO mode or keep at 35?

Just messing around doing carbon filter maintenence, cleaning dust off dust filter. I was able to see that venting back into grow room rose the rooms RH and made dehuey work harder.

I was able to see that moving more air lowered rh when opening doors. The intake vents are pretty narrow and screened. I removed light proof mylar from all vents as I see moving more air is helping.

But cannot go lower than 50, last time I had obvious obstructions that when removed, lowered rh to 45. Though buds are forming and as I had experienced before with a full tent of green, rh gets harder to lower and keeps rising.

I think it was at 50 as is until today it climbed to 55 for whatever reason, that was the highs on the hygrometer. Electric bill gonna be high if I keep running like this. Partly why I put so many fans in there. Help equalize rh, I see it happen with fan in room.

One side of room is higher in rh than the side the dehuey is on. So I move dehuey closer to tent and turn a 16” hurricane on which moves a lot of air. Equal rh per hygro meters. Any suggestions let me know. Going to re-read some of the already suggested comments.

I feel like under packing the space with dehuey working less harder equals cheaper weed which is better than riding on the line. Some say 45 is pushing it, some go up to 55, some 60. As a budrot victim I say 45 is good.

On water/feed days it will take a little spike in r/h. Are you able to push you air coming from your tent anywhere else but the grow room? That should help.

Yea I built it to draw air from another room and vent outside and just about everything else I can do beside cranking dehuey on full. Its dtw coco so its always water everywhere all the time.

 

[medidedicated]

I didnt think I was jam packin it already but its just about as full as it can be I guess. But every bud has good space to breathe, canopy is thin and exposed to light. I guess thats hydro for ya, no plant problems but problems with plants being too big lol.

Yes I -c. Are you running photos or autos?

Photos, vegged for 6 weeks just anout, one flipped earlier than the other and took longer to switch.

50 to 55 in not too bad. I run soil so dehumidifier handles it down to about 40-45 r/h. Did you lollipop at all? That's a long veg time if you don't lollipop

Yea I lollipopped both plants, one grew much taller than the other. About to switch to 8 small plants in a half gal or one gal coco but hope rh doesnt go out of control. These are in 3 gal which is overkill but they are about done with most of their structure.

Dust filter clean as can be. Pretty simple, just speed wash and dry it by itself. Putting hand above it can feel much more air flow. Removing mylar blocking vents for light proofing along with washing the heavy dust off, got it down to 50%rh.

I worry its going to keep climbing as buds grow as they throw off a lot of moisture IME. Hopefully I can keep it at 50 but it was 45 with the same amount of leaves. Only difference is theres buds now.

Back to 46Rh but dehuey is cranked high, almost the highest setting, CO. Right now on 35. It just took a break so thats good bill wise. Hope it takes more breaks. Usually at 35 it keeps going but I didnt set up ventilation like I did here this time.

So thats good, more control over RH still. Not much though. Should be able to call it safe in late flower, shouldnt notice changes in rh for rest of grow. Kongs krush supposed to smell like bannana cinnamon and it does, I am pleased. Not even late flower yet where its peak production resin/terps.

Welp, dehuey set to CO because the buffer allows rh to go to 55 in tent or 50 on a good day, 45 less commonly but was a good sight thinking I had more capacity still.

I did but it just kept hitting the higher side and now the 5 unit buffering that most auto function devices have to protect the device in use.

Did not consider winter and if it will blow clouds out the vent like a dryer vent in winter. Not sure. Also not sure Id change anything, yes the tent is running cool at 68-74F, sometimes closer to 68 during lights on.

But the RH and dehuey behaves more. Dehuey might work better with a enviorment controller like inkbird. So I can control it to set it so it isnt always running which is going to cost a lot quickly at 500w.

But wow is this a great run, about 1.5 months left or less. I can easily figure out a way to get some of it back. With dehuey on CO its been 35-44 RH but turned it down mid night. Was too tired to think something through. Just will keep tinkering with it.

 

[medidedicated]

It was set to 35 but wouldnt turn on until it hit 40, sometimes 45rh. But it has capacity to not be on all the time but barely. It used to run all the time venting back into room and these days can see meters raising in rh immediately when I disconnect duct for maintenance.

The setup was working perfect and this is just giving the setup a run for its money, everythings cranked up to max. I can feel the thin ice I am on but based on my best opinion, I think I will make it but with a bill to pay. Bud is good enough to get rid of itself though so not worried bout it even if its all for me. Lovin this bananna strain!

I would freak if power went out mid way through this or at any point passed the mid flower period. In short I went black friday shopping afterall and got a gas generator. So that will be black out proof and can chill at home and not lose any food.

Thats the last major purchase for the grow. The rest is just scrap, minor purchases. Now just need to get to yield and get my stuff together and runnin. Will already start seeing it pay itself off immediately as I start yielding.
