Automated SGFC (Advice Wanted)

Here are some videos of an automated misting and fanning technique that I’ve come up with. I’m gone for 48 hours at a time so I needed to figure a way to get them misted and fanned and the lights turned on. That said, this seems to me to open up a whole new world of possibilities and questions. As far as I know, I want to mist a few times a day and fan even more often in order to cause evaporation which triggers pinning. I have coded out an algorithm which turns on my 6500 Kelvin lights at sunrise and turns them off at sunset and then mists for 20 seconds every other hour between sunrise and sunset and fans for a minute every hour between sunrise and sunset. (That’s twice as much fanning as misting). I’m wondering what the ideal schedule and length would be. Should I mist and fan throughout the night as well? This was a previously unrealistic possibility as no one would want to wake up throughout the night to do this but now I can automate it. I also have a CO2, humidity and temp sensor in the terrarium which is tied to my smart automation system so I could also trigger my fanning based on CO2 ppm metrics and trigger misting based on humidity metrics. Not even sure where to start on that though as far as numbers. It does seem to be around 700 ppm of CO2 before fanning and I can get it down to 200 ppm after fanning but all this is dependent on what stage of fruiting I’m in and how many cakes are fruiting. The relative humidity seems to get stuck around 100% after a while which makes me wonder if the sensor just gets over saturated. Any suggestions on what would be the ultimate schedule given the ability to automate it?

They're already automated. And if you're automating something it's not going to be a sgfc with cakes in it lol. Fanning is basically pointless.

So are you saying that fanning is not necessary with a SGFC? There is sufficient FAE just with the holes? And misting also isn’t necessary with a SGFC because of the humidity provided from the perlite? I’ve never heard this. How did I miss this?

Holes are for FAE and also letting the water evaporate off of the perlite.
A SGFC is an attempt to automate humidity + fresh air exchange.
I recommend Humidity Chamber tek for less interaction.

i find misting and fanning a sgfc to be the most successful way.. also you can simply automate this by having your sgfc in your shower with it on (3 drops a second) with a fan on top of your sgfc.

Sgfc has hundreds of holes it gets FAE 24/7 automatically. If you can't be around to mist every other day at the minimum maybe growing isn't going to be an option. You'll miss a harvest and have spore explosion if you cant visit your grow at least 3-4 times a week.

Add on top of that the fact that sometimes I don't come home at night (staying at the girlfriend's) or have the occasional business trip lasting several days.
It was made by RR when he was working 10-12 hour shifts plus travel plus having a life as a way to not have to babysit cakes. And to handle cakes for weekend trips with no one around. Requires less work than brushing your teeth twice a day. Mist em once in the morning once at night. Basically one of the most automated FCs for cakes that there is.
You shouldn't be measuring humidity anyway. Pay attention to the cakes not some ridiculous gauge.

Says who?
Perhaps for 'best' results, it should be fanned with the lid whenever you mist, but the fact is, I and many other people who work long hours have left them unattended and had excellent results. I've left a shotgun terrarium full of fruiting cakes closed up for over 24 hours, and the CO2 level has never exceeded 1000 ppm. RR

I designed it when I was working 12 hour days, with an hour of travel time and couldn't be there for 14 hours per day, and still needed to sleep during that off time.
You mist to make up for substrate moisture lost due to the automatic fresh air exchange, which happens even at 99% humidity. There is no free ride. If you put an airstone and bubbler in the terrarium, the slight positive pressure that is created screws up the operation, destroying the entire principle that makes it work. RR

If your hygrometer is electronic and wasn't expensive it will get completely saturated and stop working eventually. Keep it in your grow are where the SGFC is so you know how often you will need to mist your perlite. Gl

Make sure the chamber is packed with cakes for best results. The more cakes you put in the better it will hold humidity.

How does that work? Atmospheric CO2 is about 400PPM...
Did I read it right? You've got automatic misting going on? What are you using for that?
Anyways, I think what you've got going on there with your schedule is probably fine...sounds like you've been doing this for awhile and its working, right?
A mist every couple hours sounds a little much to me, but as long as they aren't getting too wet, its probably fine. Your going to get a lot of evaporation growing in a SGFC.

Sounds like way too much misting to me. Also, depending on what kind of spray setup you have the water droplets might be too big. You want a really fine mist, a mist king system would work pretty well, but most cheaper brands, such as a zoo med spray really heavy. Same with gardening systems. Pearlite should keep the humidity where it needs to be as long as there is enough, and you don’t have a fan blowing directly on it or something stupid. Your humidity gauge will never be accurate in an environment like that. A mechanical unit will build up moisture inside of it, an electrical one the moisture will ruin the sensor.
SGFC are a really simple system and no offense but imo you’re over contemplating it. When I did them, I might fan once or twice a day. And a light mist with a pressurized hand sprayer very rarely.
Set up the right way I’ve left mine alone four to five days no problem.
Sounds like you have put in a fair share of work. Something like this would be awesome in a different style fruiting chamber, for bulk. Just my opinion! Best O’ luck!

Bulk chambers are even more automatic yet. Using computers and sensors for automation is what people come up with when they don't have any experience growing and didn't do enough researching. The Chambers we use these days are passively automated.
Misting a chamber once a day to once every few days is less work than cleaning humidifiers or filling them. And if you've never grown before youll be spending weeks and hours babysitting to configure the automation to actually work.

I've also been thinking over automation, and it seems like a length of misting hose plus two check valves, a water pump, and an air pump (to blow the line dry) on a programmable timer or tied to a controller would work.

Could you elaborate on how you use your humidifiers? I run one in the house to keep the RH between 45-55%, but not directly in or next to my SGFC. Mine doesn't have any options for programming or turning on when power is applied, so I have to start and stop it manually.
