Ac infinity fans

I bought toolazy, terrabloom, and ac infinity 8” inline fans and toolazy was way weaker that the other two. Terrabloom wasn’t bad but ac infinity clearly took the lead.

After messing with this controller fan/clip on and the smart plug for a couple hours...im digging it. Took a bit of messing with it but I think its going to be sick. The smart plugs are awesome. I can cycle my pumps and run my lights all from my phone. I cant wait till the tents come and i can set it all up

The controller 69 has made it easier for me to tweak settings and tighten up the tent environment. Their newer graphic (in the app, that came out about 6 months ago), has helped me set up a couple different automations, one for dark, one for light & adjust from there. Right now I'm happily sitting with a VPD average of 1.1 and really only deviating by .2kPa or so.

My controller 67 humidity was way off. I had to offset it by -6% but otherwise, it works well.
Yeah, I use the same sensor with my 69 that I used with the 67 and the original digital controller, and I've had to adjust each along the way. I haven't done a full calibration for humidity & temp in a while, so I should do that again. I have the Inkbird Temp & humidity sensors as well and usually suspect they probably hold closer to true across time.

How did you double check it? Alternative sensor? I have a viviosun temp and humidity monitor i though about double checking with but what if its off too lol

I have a lot of those cheap Vivosun monitors and each of them reads within a couple % RH of each other; temps are also within a degree C. But the AC Infinity probe was reading +6 higher, though temp was good. It isn't a very accurate setup since the lowest common denominator is VIvosun.

Fill a bottle-cap or super small tup with some salt and moisten it with water enough so that it's sort of 'wet sand' consistency. Put that in a ziploc bag with your sensor end and seal that badboy shut. Let it sit for about half a day to normalize and the reading should be 75RH. If not adjust your offset so that it is.

Whhhaaatttt learn something new every day. Im going to try that with a few of my sensors. Now im curious to see what they all read...maybe my flower isnt at 58% ohhhh geeze

I drilled a 5/32" hole in a small plastic spice bottle I had which matches the probe diameter. Put some salt and water in it and wrapped the top in plastic, we'll see what happens.

Last time I did this I used a quart sized ziploc with a top off of a small (2x2") tupperware container to hold the wet salt. Put all of my humidity probes in the bag and sealed it up right up against the cords, taped that with a bit of tape and then just left it for most of the day. Made sure there was a bit of air in the bag so the moisture had something to evaporate into.

And Maricopa County wants to show you how to calibrate for temperature (at freezing):

Of course, anyone who uses pH and TDS meters knows it's better to have multiple calibration points, but that's above my pay grade...

Mine is hanging right at 70%. Which is weird, because I should have to adjust about 5% in the other direction according to all the cheap Vivosun meters.

I'm guessing container volume, salt weight and water weight matter for this to an extent.

After leaving the probe overnight, I only had to adjust +3% RH so the Vivosun hygrometers are reading 7-10% low. In the specs, they show a margin of error of +/-5% which is a 10% swing -- basically useless. Temperature is relatively accurate at least.
