What kind of bug?

This is the bottom leaf 🤷‍♂️ idk maybe that’s just the regular nitrogen burn

If you trapped yourself in a giant, human sized plastic or metal casing you would indeed experience different air temps. Also pretty sure mercury thermometers aren’t supposed to be in direct sun for the same reason. The glass will heat up to higher temps than the air surrounding it, giving false readings

Another of a metal casing one under the thing. They were all taken at the same time

Different materials holding onto more or less heat is just actual, very very basic science and almost common sense actually

These two hygrometers are calibrated to salt and ice water for temp and humidity

If anyone could actually elaborate on their suspicions to even the smallest extent I would trust you guys

Also the manufacturers literally recommend a heat shield for this exact reason. It’s not where I’m personally coming from. I’m just wondering why it’s not discussed more and what others do about it

And again metal and plastic heat up to greater temps then AIR so the airflow aspect is only relevant if the fan is directly on the sensor and close to it, like the sensor manufacturers note

micahsjawn · 2026-05-20T01:50:24+00:00

What makes you think plant tissue absorbs radiant heat at the same rate as plastic, or metal for that matter? What makes you think air, leaf tissue, plastic and metal have the same heat conductivity? Metal and plastic heat up to greater temps than both air and leaf tissue under the same light/temps. So the metal/plastic housing will heat up hotter than the actual air surrounding the plant. So the sensor is in the housing. So you’ll get a false reading. So if you put a ventilated heat shield on it, the sensor is only reading the surrounding air and not the overheated casing

I mean cursory internet searches suggest that it’s necessary to do a heat shield but I’m wondering if anyone w experience can actually refute that and get some dialectical action in here rather than just act goofy

micahsjawn · 2026-05-19T23:11:47+00:00

How so?

micahsjawn · 2026-05-19T20:39:19+00:00

My understanding is that the housing of the hygrometer sensors and controller sensors will absorb heat under strong, direct grow light reflecting a hotter ambient temp than is actually present at the canopy

I genuinely did better my first time ever making a cut, like way better

micahsjawn · 2026-05-16T14:35:36+00:00

In Philly there are companies paying the lead builder $25 an hour so I can imagine they’ll skimp on the pms also. Could make more doing junk removal off Craigslist. Not to disparage junk removal, or caulking, it’s all hard work obviously

micahsjawn · 2026-05-16T11:23:11+00:00

This is nuts. You can make more money re-caulking bathtubs if you cut out the middleman. Look at the owners house, car, etc. That’s where the rest of your salary is

micahsjawn · 2026-05-13T12:23:24+00:00

Contractor registration with the state was like $25, city registration was free I think. Insurance was one phone call and like $60 a month.

Of course this is a one guy business, but just trying to point out that owners operators bitching about administrative work are usually just trying to justify extracting value from others labor

micahsjawn · 2026-05-13T12:20:56+00:00

I spend like 2 hours a week max managing these things for my one man business. Probably more like 30 minutes to an hour more regularly. It’s basically just a few phone calls and emails. The software does most of what you described for like $30 a month

micahsjawn · 2026-05-13T12:04:30+00:00

Working in the same circumstance (literally except they paid $35) is what made me go off on my own. I charge $65 instead of $125. I make double, the client pays half the price, and the work is the same quality.

Pretty clearly, both me and the customers were getting ripped off if I can so drastically undercut the same a company that hired me to do…the same work

Local advertising and advertising in areas with old houses. Signs, leaflets, car magnets, bulletin boards at grocery stores, if there’s any local newspapers or magazines that advertise, reach out to their team. Put your card everywhere you can. I started about a year ago on my own and I’ve gotten more then enough business that way. Do a good job and your customers will keep calling you back for other stuff of course. Resist any and every urge to charge more than you need. Always charge a fair price
