No word from my friend about talking to the landlord. But he left his hat in my car so I will hear from him sometime.
In the meantime, I have been working like a dog the last two days updating the ventilation system on the indoor stealth cabinet. My initial design had a number of flaws, and temps often got up to 90 degrees a few inches above canopy level after 12 hours with my 250 watt HPS, even with my cooltube.
I fixed it on the cheap. But quality. I also redid my carbon filter, as my previous DIY attempt was no longer effective after 10 months of use. This new one works better and should last a full year. And the results with this fan after one night are amazing. And halfway through the second night, they look better. I have it on the lowest possible setting, but it is not too loud even at full blast.
I took a ton of pics of the process and might make a tutorial. That will come later, if I get bored. Right now, I am still busy working on a cleaner wiring scheme for the computer fans. In the meantime, I took some pics of the finished product. Keep in mind, I still have tons of work to do, but am simply sick and tired of working in there and it is good enough for now.
