This. Is. Awesome.

I currently have a Monster cooler like this that is set up as a curing chamber with a simple temperature and humidity controller.

I would love to be able to integrate something like what you made into my setup. The data logging and interface are super nifty! Definitely let us know when/if you pull something together.

I use these.
They last about a year or two, I have yet to have one last over 3. Just due to the spore and high humidity, but they are super cheap.

Want to start by saying I'm definitely no shroom-growing genius yet. This is just my current setup, and a bleg for comments/ideas.

I'm just growing for myself. My brother died 1.5 years ago, and I've subsequently started microdosing shrooms, which turns out to be an absolutely fantastic antidepressant. So I'm more interested in "cheap, consistent, and reliable" than I am trying to churn out a kilo a week.

My setup is:

• A 4-tier greenhouse
  
  
• A Vicks cold humidifier on the bottom shelf
  
  
• A water fountain mist maker on the top shelf, inside a random bowl from my cupboard
  
  
• Two fans in the tent to help circulate air One is at top blowing down, the other is at bottom on the other side of the tent blowing up
  
  
• A humidity controller (the humidifier and mister are plugged into it) to help keep humidity in the right zone
  
  
• A Raspberry Pi 3 with Sense Hat so I can log temperature and humidity and log into it from work to check
  
  
• The tent is sitting on an upside-down lid from the largest tote I could find at Lowes. This allows air circulation under the skirt of the greenhouse, and helps capture any water drips to ensure I don't get water elsewhere in the room.
  
  
• Two plastic totes from Costco (sorry, can't find a link), with holes drilled in and filled with polyfill, similar to this.
  
  
• A 20 W night light bulb on a 12 hour timer on the top shelf.
  
  According to the Raspberry Pi, the average temperature in the room is 62 F, with a bimodal distribution (my girlfriend loves AC...). It's 65 F when I'm here alone, and 60 F whenever she's here. Humidity varies between 65% and 75%, though I'm still working on it. It's rather hard to boost temperatures in that particular basement room.
  
  The shrooms are growing very slowly. They started pinning 3-ish weeks ago, and still don't look anything like the giant mushrooms I see posted here regularly. My "biggest yielding" tub currently looks like this. No giant shrooms, and rather sparse inside. Furthermore, a large percentage of the shrooms have been there long enough that the caps have turned black. The other tub has a few tiny pins but no growth yet.
  
  So what do I need to be doing differently in order to improve my growth/yield? And are those black cap shrooms still good? Any comments would be greatly appreciated.
  
  Things I've already learned this round:
  
  
• Paint the bottom of your totes black or cover them with tape to prevent light from getting in. My totes don't have many shrooms as-is, but right now 2/3's of them are "side-dicks" that are impossible to get to.
  
  
• Regularly rotate totes between shelves, as well as rotating them around on the same shelf, to ensure reasonably equal amounts of sunlight and air.
  
  
• Even with a humidifier and a mister, it's hard to keep humidity in the zone. Use a squeeze bottle to mist totes every day.

The manual SUCKS but the product is solid. I have two of them, one for each tent

I work in a pet store. When I was looking for a humidity gauge, I looked at the ones we had and none of them showed the same number. I wound up getting this: https://www.amazon.com/dp/B076LMFRHG/ref=cm_sw_r_cp_apa_sOJOBb49V7WB0

It also controls my humidifier. I just plug it into the outlet and set a range and it turns it on and off to maintain that setting. Probes are replaceable in case it ever goes bad.

So there are actually two components here: the sensor component with power shut-off and the actual humidifier component. The sensor component I'm using is the WILLHI WH1436H Mini Plug-n-play Digital Air Humidity Controller with probe from amazon - that's the important part. It lets me set a 'start' range and a 'stop' range. So it goes 'on' whenever the humidity drops below 60% and stops when it hits 75%. I had to calibrate it a fair bit because I've got the sensor on top of the tank rather than IN the tank (so readings of 50-65% actually match tank readings of 60-75% I've found) but after some fiddling it's worked like an absolute charm.

​

This works with any humidifier, which is great because those components break more - but the part I'm using for that is Evergreen Pet Supplies Reptile Humidifier/Reptile Fogger - 2 Liter Tank also from Amazon.

Also purchase a humidity controller, with that many plants and that space running humidity constantly could be devastating if it wasn’t regulated.

I use this and set a min/max range that I want to have, the humidifier kicks on if it gets too low and kicks off it it exceeds designated range!

I’ll do that, was also thinking about one of these: https://www.amazon.com/dp/B076LMFRHG/ref=cm_sw_r_cp_api_.Ux.BbR0KRZBQ

So I did a similar size cooler that's working fairly well. I'm using two controllers similar to the Inkbird, one for temp and one for RH, but DARNIT (pardon the language :-), mine is only either humidifier or dehumidifier mode; I can't run both! Usually that's not a problem, as the meat's usually giving up water and I want to run the dehumidifier, but the thing can overshoot as it's not an autotuning/learning PID. Also, you get a "dueling temp/RH" thing where the fridge cooling kicks on, temp drops, the RH changes, so the humidity sensor triggers, etc. That usually converges to a stable state, but requires some fiddling with your high/low set points on both temp and RH controllers, plus the other params. Sorry for going on, but even with the dual controller Inkbird (which I'm now going to buy - thanks for the info!), this is something you'll be dealing with a bit. Note that your unit has a water tray (I looked up the manual - it's a CWC-3200 right?), "to receive condensation drained from the interior", so when your cooling kicks in it'll be dehumidifying too. AND if it's bringing in outside air, it'll be mixing that RH in. So, good thing you'll be running both 'sides' of RH control.

I can suggest a dehumidifier that I like just fine. Everybody seems to get the odd teardroppy thing; I got this one about a month ago, which is more compact (I think) for $40 and love it. Suddenly now there're a ton like it for $35 or so, and now I see this one for $30. For a humidifier, I got one of these ultrasonic/wick things, and opened it up and am modifying the switch with a dab of solder to be "always on" (it's momentary and goes auto-off when it runs out of water), but again my controller is either/or, so I've not been using it yet. However, apparently the little $10 ultrasonic things like this just set in a reservoir of your choice are a no-brainer.

You'll want a set of S-hooks. I find the smaller the better as you've got limited vertical space. You'll want to think about how you're going to hang them in the cooler - those wine racks are going to be a bit of a PITA as you're limited to the bottom center of each bottle-holding wire and then the crossbars.

Best of luck! Andrew
