Thirvnrob's Power Plant - TLO Soil In SIP Containers

[Thirvnrob]

Let's call it Selective Air Exchange. We'll copyright the term & build an empire...
All seriousness aside, I already have the exhaust set on a timer - 15 minutes on, 45 minutes off. I think you're telling me a different approach might be in order? I could do away with the timer & use the exhaust as necessary? I'm not really worried about odor...

 

[InTheShed]

It's a big space to try to force a dehuey to deal with when you're bringing in that much damp air. I'd say a different approach is definitely worth a try.

At my house the outside RH is low during the day this time of year but still gets into the 90% range at night. If there's a time of day you can bring in RH in the 50% range then that would be when to run the exhaust. If not, try 15 minutes every 3 hours and see how the dehuey does with that timing.

Not the best approach in a tent but in a room like that I think it will work.

 

[Thirvnrob]

I would close the vent and blow the air around, which eliminates the need for the filter unless you want to take down the smell in the room itself.

Or if there are times of the day when the incoming RH is low, you can put the exhaust fan on a timer and bring in fresh air those times and have it off during the times the incoming RH is high.

Lately, the RH has been between 85 & 96% over 24 hours. It's ridiculous here. Literally, the RH could be in the 40's tomorrow night, then the 50's, then back into the upper 90's. Same with temperature fluctuations this time of year...

 

[InTheShed]

Start with a much longer timer interval to give the dehuey a chance and see how you go.

Well, I guess my instincts were correct about using a timer, just off with the on/off ratio. I was worried about air exchange.
My main problem is that I can't close the door to the grow room. The A/C is in the adjacent room, which isn't finished. it has occurred to me that finishing that room will alleviate much heartburn...

 

[Bill284]

I do have a good exhaust fan. problem is, I'm pulling humid air into the room, dehumidifying that air & then sucking it out...

I know what would help.
Take out that little chair.
And put in a big reclining Lazy Boy.
Preferably the one with the built-in cooler.
May not help rh but you'll be more comfortable sitting thinking about it.
Sorry can't help myself sometimes.
The room your drawing air from, how hard would it be to drop the rh in there first?
Take care.

I have a window A/C unit in that room that also has a dehumidifier which I employ almost every day. I have a pedestal fan close to that unit blowing dehumidified air into the grow area. Live & learn. I hope to add a portable A/C by spring. Venting it would be a snap...

Will do! Thanks! I thought I was doomed to failure without constant air exchange…

I built the shop myself from the ground up. My son in-law is a master electrician who coached me through the wiring process. Some plugs are specifically designed for 20 amp circuitry but they can also look like normal circuits. The outlets themselves are rated for 20 amps. I'm confident in the way it was done...

you can install 15a receptacles on a 20a circuit just fine, but the receptacle won't accept a 20a plug then. you need the 15A receptacles for the common equipment, i'm assuming you mean you have both types, just all on 20a breakers.

the alternate is to build adapters yourself with a 20A male end, and a standard female end for the lower amp stuff. i do it all the time. i actually run my welder on a 30a dryer receptacle and built a dryer to welder plug adapter.

Lately, the RH has been between 85 & 96% over 24 hours. It's ridiculous here. Literally, the RH could be in the 40's tomorrow night, then the 50's, then back into the upper 90's. Same with temperature fluctuations this time of year...

that's a crazy amount. definitely in dehumidifier territory. how big is the extraction fan ?

i'd try shed's suggestion of opening the space up to help.

if that doesn't fly the next step would be a massive extraction fan on rh control. my rh rises over 30% in a half hour in flower if i turn the fan off. i go from 50ish to well over 80, usually closer to 90, and i live in a low rh area. current ambient indoor rh is 35%. i run a huge snail though, and it runs 24 / 7.

15 & 3 seems to have done the trick. I've been in the VPD sweet spot all day but I did find a big ole dew drop on a fan leaf today. I imagine there'd be a bunch more than that had I not gotten a handle on it. I still see faint evidence of pm but I'm not stripping any leaves just yet. I like living on the edge...
Thanks for the suggestion. I thought constant air exchange was a must. I guess i could've saved a few bucks...

Here’s a mid- grow report. So far, so good. Aside from the one Ill timed top dressing, I’ve given these girls water only. I’m learning to trust the process & stay out of the way. I’m plucking a fan or two every day. They’re still trying to crowd each other out - I try to not let them.
We all know something is amiss with my SIPs - they’ll only take two quarts of water at a time. That said, this is still my best grow so far, part of which I’m giving myself credit for building a good soil mix. I netted some good learning through that process.
I’m loving the SIPs - they get the rest of the credit.
So without having to worry about feeding the girls, I’m more receptive to learning other things, like PPFD & DLI. I’ll never fully grasp the theory, but I can understand the basics & read the light meter I downloaded to my phone…
So, with all this time on my hands now that I only have to water, the missus & I were in the same mood the other day, (ahem) & well, um…

So, here we go again! She got me the coolest gift ever for Christmas - 5 Sour Diesel seeds. I’m going to journal them separately but I wanted to show these here. One looks like she has one coty & miniature true leaves opposite that. Those with wisdom please reveal yourselves…

You know what? Screw the RH - I'm buying a recliner!

 

[InTheShed]

Congrats on the seed drop and you and the missus being in the same mood at the same time.

I’m more receptive to learning other things, like PPFD & DLI.

PPFD is just a better way of accurately measuring light the way a plant sees it, and DLI is PPFD x hours per day. It's a way of measuring how much total light the plant is receiving per day.

I did an explainer on DLI here if you want a quick read.

I’ve read it sir, thank you for sharing it!

I was thinking she might be a dud, but maybe not. Every girl I’ve raised that started out with some anomaly has turned out to be a star so I’m giving her a few more days to thrive…

 

[InTheShed]

I'd give it a least a week to see if you get a second set of fans!

 

[NickHardy]

Leaves, right? Not to go with the Lay-Z-Boy?

It looks like she's trying, right?

It looks like she's trying, right?

With a pair of true leaves you're always better off than with cotyledons and then nothing!

I know she has to work harder with only one coty. This will be a heartwarming story of hope & courage...
