Yeah those sensors are cool and nice tools to have for dialing in rooms/tents quick. You can set the intervals for each unit to whatever you want, I have them set to report every 15 minutes which gives me 2 weeks available for download if I want to keep the history. There's an app or you can just use a web browser to access the dashboard anytime.love the soil temp data, wish i had some sensors set up to document my rooms conditions. Are you able to access the data in real time over the web? if so what kinda set up do you have? sorry about all the q's but I've been wanting to monitor grow conditions from away from home.

On the newer one's each unit has 2x temp sensors, one is on a cable so you can measure temp at 2 levels at the same time + RH wherever the unit is sitting, you can see the one in the flower room, the white thing on the left wall. it's one of the older one's and just measures at the unit level, I try and sit it at canopy level and middle of the footprint. They're wireless so they can be moved around and the attachments like the wet sensor just plug into the bottom. It can be used in water like my cloner, or soil. They're not that expensive and I just replaced my first one which was around 4 years old and bought another so I have 4 now. I only have one of the wet probes and I move that to any unit.
You have to buy one complete kit with the station, and then you can connect up to 5x sensors to that station. here's more info on them.

People are Co2 sources....Co2 being heavier than air...basements are below ground...common man!Only one with CO2 sources. That's why I asked where it's coming from?
Yeah I get it, I think it's a variable in a house depending on activity. You're right on the gas, water tank and dryer sit down there, they're both gas. Everything else like washer, stove are electric.Wherever it's coming from, a little excess CO2 is of course not a bad thing- I'm just the type who needs to know its source.
Are there people and/or pets in the house all day? Water heater? Anything else using gas? The outside environment is now above 400ppm worldwide, at least a third of which is a direct result of human activity. I'm just curious about the difference between that and what you're measuring. It's possible that if you're close to a busy road you might be getting it there?
And that's fine if that's the cause, bro.People are Co2 sources....Co2 being heavier than air...basements are below ground...common man!
I'll say they are (people), I went into the room and it was sitting at 540'sh, closed the door and stood a couple of feet from the sensor for about 5 minutes watching it go up. It was still increasing as I took the pic below, it increased by 200 ppm by the time I left. Lesson: Spend more time in the garden - lolPeople are Co2 sources....Co2 being heavier than air...basements are below ground...common man!
We exhale 2200-2500ppm with every breath.I'll say they are (people), I went into the room and it was sitting at 540'sh, closed the door and stood a couple of feet from the sensor for about 5 minutes watching it go up.

We'd have to, to make that much of a difference and that fast in a 4x9.5x7' room. Or I could just be full of hot air as they say - lolWe exhale 2200-2500ppm with every breath.
My concern was for the nature and safety of the source, that's all.We'd have to, to make that much of a difference and that fast in a 4x9.5x7' room. Or I could just be full of hot air as they say - lol
Oh yeah realize that, always good to know the cause. Looks like just normal daily activity can increase it in the house quite easily, but it also seems to drop back to normal levels quite fast. I really hadn't looked at or considered CO2 levels. So far looks normal in the 500-600 range throughout the house, basement looks more like 600-800 depending on what's going on. Pretty sure the first readings I grabbed were higher due to having the washer/dryer going all day (dryer is gas and so is the hot water tank supplying the washer).My concern was for the nature and safety of the source, that's all.
Basements are awesome places to grow for lots of reasons lol
Yeah the science is there and makes perfect sense for CO2 supplementation. I personally wouldn't bother as I grow more than I need as-is and it looks like a pain in the ass, plus red flag (carrying tanks in/out of the house) and more work. The alternative imo is getting them as much fresh air as possible which I'm doing already.The conventional wisdom is that 1500ppm is best for growing plants faster.
There is also plenty of research that shows plants growing fewer stoma in such conditions, because they don't need as much surface area to take it up.
I've also heard that some people are experimenting with running their CO2 supplementation in bursts, although I haven't seen a lot of numbers on the timing.
I'm running mine in one hour on and one hour off cycles during daytime hours, my thinking is that I don't want the plants to get used to a constant high level and see the effectiveness of the technique be undermined.
^^^ that right there is the #1 reason I wouldn't bother ^^^Regarding tanks; when you do a weekly run for the tank refill, someone will notice eventually.
