Hi,
I recently stumbled on a nice empty house at the fringes of my city. The homeless people are generally treated like shit under capitalism.
The house had a trapdoor, to a cellar. If it had been closed, maybe with a carpet no urban explorer would find it. Now all stuff I am writing is purely hypothetical, and I don’t intend on doing any of this.
The cellar is pretty empty, It has an empty shelf, where you could store can food, a mattress is very easy to come by, batteries can provide electricity which can be swapped out every week or something like that. So a homeless person could easily live there.
The only real challenge, which could really destroy the whole operation is ventilation. The air is pretty stale, and if the trapdoor is closed I only really see one small window which is blocked by leaves. Leaving this unaddressed could be really fcking dangerous. No questions that CO2 sensors have to be installed, but that is not enough. There needs to be ventilation. But there are 2 constrains:
- it has to be quiet. Urban explorers cant hear a constant humming
- major changes can only really happen in the cellar, and shouldn’t be clearly visible to the outside.
Fortunately I can work with micro-controllers enough to do some stuff. I thought that I run 2 pipes out of the window, roughing them up and covering them with a camouflage net and then leaves (making it look like it belongs seems better but idk how). Then I put two computer fans on it, one sucking one pulling, and they run pretty quickly at the day, when no movement is detected, turn of if movement is detected and don’t run / run very slowly at night.
I have no expertise on ventilation at all, maybe someone can share their ideas and expertise, providing an alternative plan, or improving upon my ideas.
Also for which gasses should I buy sensors? Safety is important, and it is important that no mold forms (no mold formed in 20 years when the trapdoor was open and noone was in there so that’s good.)
Hey, a question I’m weirdly able to answer as a maintenance guy and grower.
You want a quiet ventilation system that runs on little power as possible?
Well, I grow marijuana [legal state] and you should consider something like this:

Yes, I know, Amazon. I don’t recommend buying from there if you can; search around online for small shops or even a “hydroponics store” located next to the local seedy smoke-shop for something similar. Explain your situation and they will absolutely help you; even if you live in a “bougie” area you can just phrase it that you’re looking for something to control humidity, provide proper ventilation to an attic area for “herbs” if you have to be so discreet. If you live in a red area; Amazon has that one use, then. Sometimes a sacrifice has to be done while you’re spiting the system ultimately if you know what I mean.
Any small ventilation system for a grow tent should be stealthy, have cheap filters and some even have humidity control. The maintenance man side says that if you are in the attic you should see if any of the ventilation runs from room to room. In the attic in my apartment there are grey, shiny metallic-looking tubing that is flexible and runs in connection to each vent in the apartment. You could splice right into one of those with your ventilation kit and not even have to physically modify anything externally/hide anything. All you’d need is a knife and duct-tape.
Being able to set up two systems to pump in at the top and pump out towards the bottom would be perfect. Seconding a Co2 sensor if you can.
