Reddit's favorite alternatives to Mini Hygrometer Thermometer Digital Indoor Humidity Gauge Monitor with Temperature Meter Sensor Fahrenheit (℉)

I sometimes use this $11 one off Amazon. It's 0.3oz and keeps a log of highs and lows with temp and humidity. I run it overnight so I have an idea how cold it got. It only goes down to 23F.

It looks like an Inkbird Hygrometer. Based on picts on Amazon the first number is temp and the second is humidity.

I believe I got a pair of these and they work great. For measuring basking spot you'll want a temperature gun for spot accuracy

Bought it in Feb (used it in a tent style greenhouse at first) is working perfectly.

$70 for the controllers and $50 fogger. Probably cheaper at a store.

Inkbird makes a cheap controller for this I’ve been looking at myself here Amazon

Last year a buddy and I both got really interested in internal air quality. You can purchase CO2 monitors like this one on amazon. I found that my office was about 700 ppm and my car varied based on whether I was using outside and or inside air as the source for my air conditioning.

We also had a co-worker that had a device that would measure PM2.5 particulates (I'm not sure where he got it from, but I'm told it was quite expensive).

The most intersting result I got from all of this had to do with my home office. I found that if I was working in it for a long time with the windows closed, I would get over 1000ppm CO2 in under 2 hours. As a result, I made sure to open my windows every time I was in there for more than 15 minutes.

This actually made a lot of sense to me after the fact because I would often getting tired while working in there, but I had previously assumed it was from lack of stimulation or laziness.

Not really going anywhere with this, but if you are someone who is interested in this topic because you have bad air quality locally, I encourage you to look around for tools that let you measure the environments you frequent.

Got them from Amazon. I have the inkbird hygrometer on the maduro jars and some cheapo Chinese brand hygrometer for my Connecticut jars.

Thank you!

I needed one that could also run the ac so the 1800watts was the main reason for this model. You can change the humidity and temperature sensor so you could change to what you need honestly really like it.

Yes and no at first the fridge would not stay above 34 rh after some research it's this model fridge and was able to tape up the sensor and now it is between 55 and 60 constantly so good...... But also think this might be because of the rain we are getting so just keeping an eye on it.

I would recommend getting something like this:

to turn off your humidifier once the desired humidity is reached. When i first got my greenhouse case the humidifier made everything soaking wet, but without it the humidity is still too low for my calatheas. This keeps it at a perfect level. Just make sure if you do choose to use this, the humidifier doesn’t need to be turned on every time manually or it won’t work.

This is what I use to control my humidifier. The fan is on the bottom shelf, pointing upwards. It's a PC type USB fan.

You are leaps and bounds ahead of the needed recommendation to start trouble shooting long before plants.

I use a Gosund smart outlet that has a few managed outlets. Some always on and a couple of USB.

I used this inkbird device last time. Little more than I need really. I might have gotten a similar effect with an AC infinity temp controlled inline fan/carbon filter instead of this guy. But it’s here now.

Congrats on the graduation to the next phase.

Yes, and Yes. It’s a Taotonics humidifier that I have plugged into a humidity controller.

Inkbird 2-in-1

You don't need it but you will work a lot harder to keep things right and it won't be as stable as if you automate it.

Seconding this. I've been very happy using this to control my humidifier and dehumidifier. You set a target RH and the acceptable range. For example, I've got my target set to 55% right now, so at 60% the dehumidifier kicks in and the humidifier comes on at 50% if the RH gets too low.

I grabbed mine during a Reddit giveaway/discount promo maybe a year back. Their official account is u/ink-bird if you want to stalk them for promos.

Alright, idk how to send pics on reddit.. laugh at me 😋.. so yeah i guess ill text it.. i have a heater set across from my grow tent about 5 feet away (its an electric oil radiator or some sh*t idk (bc its colder in my basement) set on a time. The NON HEAT PRODUCING small bright light inside, fan in tent, and humidifier thing all on another timer (same device). The humidifier is outside pumping air and moisture in at once. Mine could use more fae but Im working on it. Trying to fan a little air into there once a day or every other day or so, to exchange air. Edit: https://www.amazon.com/dp/B07GQWY9HM?ref=ppx_pop_mob_ap_share this is the timer device i use

The differential is how much variation in the temp you'll allow. So if you set it at 25c with a differential of 5, it will allow the temp to fall to 20c before turning on. For Celsius, I'd keep the differential at 1 degree. I'm in the U.S., so I keep mine at 74F with a differential of 2 degrees so it turns the heat mat on if the temp falls to 72F. It does a great job and so does the humidity controller, which works the same way.

Here's the link. It's the combo of the temp and humidity controllers, but the temp controller is sold separately as well. It's the link to Amazon in the U.S. but I'm sure it's probably available everywhere.

No I don't, I should test that. But its in a basement so Im guessing it'll be a bit humid and cold. Something like this looks pretty dang cool though. Is it essential do you think? Or just checking once/twice per day and turning on humifier/dehumidifier to adjust should work?

I have this arriving tomorrow:

I actually only bought one item from Amazon, the inkbird temp and humidity sensor. Link below. I had an old stand up freezer, a humidifier, and a little fan already. I started trial running it last night before I started drilling holes in the freezer and it works perfectly! I have a separate temp and humidity gauge coming to confirm at various points in the freezer, but so far so good.

I see a number of them on Amazon, but I guess if this is something you are worried about, you would be better off spending the money on an air-to-air exchanger; if you do have a problem, that's what you will solve it with anyway.

60/40 coco/perilite, fed her tomato nutes from Dr. Gold Pure Earth (1-1-1) and did basically everything wrong, but she's still going! Amazing plant!

​

For the jars (if anyone is interested) I bought some glass amber jars that had plastic lids, some silicone waterproof sealant, used an electric drill (that cost like 25 bucks at Walmart), a 1 3/4" holedozer bit, and these round hygrometers from Amazon. Took about 30 minutes to get it all done as someone who is NOT very good at crafty things, and lids were dried by the next day.

​

I tried to stab the holes with a knife - bad idea (hence scratched up lids lmao). I bought a 1 1/2" holedozer and it was definitely too small, we had to use sandpaper to get the hole big enough to fit the hygrometer inside. The 1 3/4" bit was questionably the right size, if not just a hair too big. Hence, the thick ass line of silicone sealant. The hygrometers do come out of the box slightly off, but leaving them out to air for like 2 hours got them all regulated. The batteries can still be accessed and changed from under the lid, so these should be able to be continually used! I just wish they were prettier, but hey, you learn right?

You plug a cheap analog humidifier in one outlet and you CAN hook a dehumidifier/fan/exhaust fan to the other outlet. You set desired humidity w/ range. It drops below range the humidifier clicks on. Once it reaches the desired humidity it clicks off.

could get a humidity controller to handle the fan on your little DIY swamp cooler setup. You can also get a plastic curtain like this one which will trap heat and humidity inside while limiting the smell.

Or get a Inkbird, it's plug and play (no wiring).

I used to use this one. Plug it in, leave the fogger switch ON with your preferred settings, and the humidistat will do the rest.

Fair warning, it beeps painfully loud if you are over or under the high and low settings.

After ~3 years boas should only be fed once every 3-4 weeks, so that's not an issue. They're hard to starve.

Try to keep humidity around 75-80% (this hygrometer is great). My girl goes blue first for about a week, then clears up for a week, then sheds. Bathing shouldn't be necessary unless the shed is shredded and incomplete.

Humidity controller with reptile fogger. Reptile fogger is top fill, so it's exponentially easier to refill than a traditional humidifier that's a bottom fill.

Myc piss is normal when FC are introduced. U want to stay in FC at this point and u do not want densely packed polyfil. That will potentially limit the natural evaporation of moisture off your substrate and reduce the oxygen that can get into ur tub. I recommend you get a hygrometer like that this one. Do not close any holes either, just use poly fill in all of them and put a fan in the room on oscillate, keep tub’s ambient temp at 70-72 degrees. Misting and fanning creates a primary pinning trigger. Use a continuous mist spray bottle. Me personally, I case with bubble wrap bc it encourages primordia growth and I fan like 3-5 times a day; on sides and lid of tub and light mist on sub, until clusters of pins start forming. Then I continue misting and fanning bc that’s what my environment requires to maintain high humidity. Yours may be different.

What I bought is more or less these: https://www.amazon.com/JEDEW-Hygrometer-Thermometer-Humidifiers-Dehumidifiers/dp/B07GR65CNT/ref=sr_1_6?crid=36WRLD6HVH6UQ&keywords=hygrometer&qid=1662913639&sprefix=hygrometer%2Caps%2C179&sr=8-6

All I’m saying is, while a home monitoring integrated hygrometer is great, you’re going to spend time finding, selecting and installing that item. If you’re in no rush, that’s totally cool. But, if you have any impatience to start considering your options, a few bucks in a hardware store will get you info the same day.

I would suggest getting another crab, as they need the company. 10 is probably the lowest to go, tank-wise for 2 little crabs. At some point, you'll want to upgrade, but for now they'll be good. It's ok to not have the best equipment right away, but if you're serious about it, try to work your way up to better stuff.

Dude. I'm using the same container and it's awesome. You have total control of humidity and air flow. I have mine on a fogger with a humidity sensor and I only need to dehumidify the thing. Put a fan on it! Set it for 82.5 and you're air hovers between 90-78% humidity! It gets fresh air every 7-10 minutes.

If you want to spend a bit more for better humidity accuracy and automated start/stop on the humidifier, I use one of these:

A humidistat sensor placed where the weed is drying will be a more actuate controller. This model works well with analog humidifiers that turn back on automatically when the power is on.

u/TheRealSatori428 has some great advice too.

What ever technique you use, a wood moister meter is also helpful to dial in the exact amount of moisture in the drying plant. I dry at 60F/60RH until I get to 11%, then cure in Grove bags or glass jars @65-70F, or so.

I tried a few of these recently and the best ones I found were actually the one that Inkbird makes.

They are like 12+ dollars... I got 4 of them and they all matched what the others said. This was not true of any of the other mini hygrometers I bought.

The Inkbird ones also exactly matched the Inkbird sensor that I use in my grow room.

I tried a couple different mini hygromoters that come in packs of like 5-12 and I also tried the Calibre 4 and none of them were accurate.

If your having issues with humidity this will be huge. Just plug in a humidifier sufficient enough for your space and program it to whatever % you want.

Not bad :)

I would put one of the slate pieces underneath the heat lamp. The lamp will warm up the slate and provide a nice warm spot to sleep on and belly heat to help them digest their food.

I also recommend placing the hygrometers more to the bottom as temps and humidity tend to be different lower in the tank and that is where your gecko resides. In my own experience these digital ones are a lot more reliable.

If you can I’d also add another hide in the middle of the tank. Something like a snake cave or zilla rock lair with paper towels inside, which helps them with shedding.

Do you have an exhaust fan? And if so do you have it constantly running?

I would recommend a very small humidifier hooked up to a controller. That way it’ll kick on when the humidity reaches a certain point and shut off when it gets up to a certain %.

This is the one I use and I love it. I also have a dehumidifier plugged into mine. I know your space is limited so you probably won’t be able to fit two of them in there but a very small humidifier would help keep the humidity up when the light is on.

Don’t worry, I think it’s great to reach out here to get info and help your kid, shows you’re a great mum :) Leopard geckos are quite hardy, they don’t die over night!

For the thermometers, I personally use these combo meters from amazon. The probe ones will do fine as well, but they can be a lot more expensive. Just make sure you calibrate them before using as to make sure the readings are accurate.

You should place them at the height of where you’re gecko moves around, which is usually more towards the bottom of the tank.

I have one on the warm side and one on the cool side as to ensure ambient temps are 90F and 70F. I try to maintain the ambient humidity between 45% and 50%, though it’s normal if thats lower where the heat source is. Would not make it drop below 35% on the warm side though.

You either want the room you keep it in to be 45-55% humidity or you can keep it in a hard case with either these pouches they sell or a reusable sponge kit that doesn't drip.

I think they make restorative packs too for really dried out gits, but I haven't tried them. Others or a local shop more have more experience with that.

I use a Niwa controller; however, those are pricey. But I use one of these for my Veg tent. It has two plugs, one I use for the humidifier. The other I use for an in-line fan that vents if it goes over a specific humidity. I have another inline fan that constantly pumps air into all my tents.

The inkbird is pretty neat. My inkbird has two outlets and two sensors which monitor the temperature and humidity. You set a range for both of these settings (a max, minimum, and alarm setting) and plug in your devices. The inkbird lets power through to your heater or humidifier or vibrating buttplug when it sense the temperature or humidity is low and turns it off once it reached your desired range of heat and or humidity. You could by a single sensor for either heat or humidity but I figured since I want to eventually transition to a martha or tent that it would be cheaper in the long run to buy the one that does both.

I have a seven dollar timer from bimart(support employee owned businesses when you can) that I bought for the light. I will plan to use the same for a fan to set the intervals. For now, while I don't have a tent or a humidifier, doin the old spritzarooni.

You can actually keep the air running 24/7 but the humidity need a control humidistat regulator Ink Bird makes one $42.00

Ink bird makes a controller for humidifier and dehumidifier. You can use any one you want, even the one you have. here

3 most important factors: light, environment, genetics.

VPD is your friend!!! Keep that link handy as you get your environment dialed in. Having a temp/rh controller like an InkBird is lifesaver.

MiracleGro is plant death - it's way too hot and will nuke your plants. Anything with "delayed feeding" is to be avoided.

After having a couple of guitars get over humidified by case humidifiers, I've stopped using them, and instead I converted one of the rooms in my house into a guitar humidor. I have a humidistat (Inkbird), and into it is plugged an LG mechanical dehumidifier and an inexpensive ultrasonic mist humidifier. The humidistat turns on one or the other devices based on the relative humidity at the sensor, so it keeps my room between 43.5 and 52% RH. I've noticed that my guitars are much more lively sounding and are very stable after installing this. I already had the dehumidifer and humidifier around, but you can get the whole set up for about $300. What I found was that for the most part the dehumidifier runs a lot more than the humidifier, because the room is over a bathroom so the humidity from the shower comes up through the floor. I have to empty the dehumidifier tank about every 1-2 weeks, and I replace the water in the humidifier on the same interval but it only really runs if we have a major cold snap in the winter or if we have a long hot spell in the summer where the house's air conditioning over-dries the air.

I used this one. It seems the price has gone up slightly.

One more thing (sorry!!!). Do these look like something I could use?

These work great for me, they use little 3M tape pieces

What are the dimensions, and the light requirements of the plants you want to put in there?

For humidity, I think you'd be better off getting an inkbird (https://www.amazon.com/dp/B0892B3VWM/ref=emc_b_5_t), that way you can monitor and set the actual humidity level, rather than a timer on off.

If it's winter right now the heat sucks the moisture from the air so you'll be running humidifier through winter and dehumidifier in summer.

This controller will turn on/off your dehumidifier/humidifier based on your target humidity.

I've never had a problem with any of my basses, but I do have a couple of guitars that are pretty sensitive to humidity. I live somewhere that fluctuates between 15% and 90% RH depending on the season. I added a humidistat (Inkbird) and plugged an ultrasonic humidifier and a mechanical dehumidifier into it. It keeps my guitar room perfect between 45 and 55%. I've already noticed that my acoustic guitars are doing better in this environment. They were actually a bit damp because I was keeping them in the cases with humidity packs but they were too wet in there and they sounded a bit dull.

Any mini fridge. I don't think they're too different, also try craigslist/etc. to source them.

You can get something like these temp/humidity controllers, and thread the probes into your fridge: https://www.amazon.com/Inkbird-ITC-308-Temperature-Controller-Humidity/dp/B01N56KEU6

Plug your into the heating/cooling outlets, and configure your temp/etc. settings. If you find you need a heat source, an incandescent light bulb plugged into the heating outlet is usually sufficient.

For the humidity, dehumidifying is typically taken care of by the fridge compressor, so you'll just need to purchase a small humidifier and plug it into the humidity controller to keep the humidity at the level you're looking for.

Get this for sure .

It turns your humidifier on and off when it needs to .you can set the humidity differential (the range) you want and it displays your humidity levels .

You really should get some LED lights a a minimum too .

These work great . They have some that say waterproof but honestly they all short out after a while.

Always keep your tent on a surge protector and have a smoke alarm near it .

I had my “waterproof” lights short out one night and they caught fire. They burned till they hit the tent but the Humidity smothered it.

I had no idea ,I was sleeping and only noticed when the lights were off the next day .

I am on my second heater, the first one lasted 8 months, and died of a power surge/ power outage.

I highly recommend the inkbird controllers to manage the my heater and humidifier.

Inkbird Combination Humidity Controller IHC200 Temperature Controller ITC308 Stage Pre Wired AC Dual Stage Outlet Thermostat Humidistat Cooling Heating Humidifier Dehumidifier https://www.amazon.com/dp/B01LL4SNIE/ref=cm_sw_r_cp_apan_glt_fabc_AY8701824VDRP1G8BKC7?_encoding=UTF8&psc=1

Between the two, you can set the exact temp and humidity, and the controllers switch power on and off as needed. You only need to make sure that the heater has a simple power switch that stays on when you unplug it and plug it back in. So, a very basic model.

I use a govee bluetooth hygrometer/temp but the alarms dont work if I'm out of range. I was thinking of upgrading to their wi-fi wifi model, I mainly use it for the graphing function , not alarms.

Here is the wi-fi version of mine.

An Inkbird humidistat is probably the most affordable and simplest solution. I haven't used one personally but it seems to fit the bill, you can set a range and switch between humidification/dehumidification. It just toggles which of the two outlets are hot, so you could plug your humidifier into one and a power strip with dehu and fans on the other.

You have to set the humidity thresholds yourself so it's not exactly VPD automation, but if your temps are relatively stable you can just pick a safe humidity threshold and leave it there.

If you want to truly calculated VPD based on current temp and chase a moving humidity target, then you will probably have to cobble together something yourself. I have a system using a zigbee temp/humidity sensor, zigbee smart plugs, and HomeAssistant (home automation software) to control it all.

VPD is calculated based on temp/humidity data from the sensor, an automation in HomeAssistant determines if the VPD is within range, and powers up/down the smart plugs accordingly.

dis right here

Also those tents are great and all but your shelves will eventually get real rusty. My suggestion is something like this with plastic shelving. That's just me though

here is a link to the thermometers i use. i love them! they're suction and digital if you're alright with that, they stay up and they're accurate! my last thermometers (don't even remember the name) were HORRIBLE, always so far off that my poor baby's humidity was never accurate and he always had issues shedding. in fact, i just found his first full shed in his enclosure this morning!!

the temperatures seem okay to me, but 82% humidity seems high, which i've been informed can lead to respiratory issues. however, i am by no means an expert! someone please feel free to correct me if i'm wrong.

hope this helps! :)

They get plenty of FAE from the 12 holes. If you want to actually measure the air quality in your tub here is a cheap meter. It may not be the most accurate like the hand held one's that are around $1k but it will give you an idea of how much air fresh air your tub is getting. https://www.amazon.com/CO2Meter-AZ-0004-Temperature-Relative-Humidity/dp/B001PDGFR8

>you plug both the humidifier and dehumidifier into one unit and the unit controls both to the humidity level you want

So this combo of controllers

Ah nice bro i dont the luxury of runnin an ac yet but hopefully gonna be able to next year.

Ah man you gotta get a few of these flower, veg, clone, dry, cure i use them everywhere honestly lol

Plus:

https://www.bhphotovideo.com/c/product/1353675-REG/juice_goose_rt_rel_ac_current_dry_contact.html

You’d connect the DEHUM contacts across the NO or NC terminals on the latter and set the switch on the dehumidifier appropriately.

Note that you can DIY the juice goose for like $0-10 depending on what You have laying around. Basically stuff an old power brick and relay (automotive works well) into a junction box.

If your humidifier does not have a humidistat and your space heater/AC does not have a thermostat:

Inkbird controllers

AC infinity exhaust fans are known for being pretty quiet. Most peoples grow tents are kinda loud tho.

AC infinity has controllers to help regulate the tent so it's not exhausting too much or not enough.

If you exhaust to the room that your tent is in, your lung room, it can cause problems (heat/humidity) but can be done. It's best to just exhaust outside.

Carbon filters work best when the tent is under some negative pressure (walls suck inward). I don't smell anything until I open the tent up.

I try to support my hydroponics stores, even tho the little things are usually overpriced. Soil is usually cheaper at the store because of shipping cost.

Depends on the RH of the environment.

Veg has a diff RH requirement than flower and curing. It's good to be able to be flexible when you can.

Our winters get SUPER dry and you'll absolutely want to add humidity to your tent not only while growing, but when curing as well.

For what it's worth, you can find some cool shit like Inkbirds on Amazon. https://www.amazon.com/Inkbird-Temperature-Controller-Pre-Wired-Thermostat/dp/B07GQWY9HM

I've got one of those hooked up to a tiny cheap electric heater and a small humidifier. You can set the thresholds for when to kick on/off or alarm.

Thank you. This one does 2 settings, maybe humidity in the winter and temp in the summer

CONGRATULATIONS, you've achieved near perfect humidity!!

80% is perfectly fine, your snake loves it.

I would, however, recommend 2 separate hygrometers, one for the hot and one for the cool side. Digital is better than analog, I bought these [beauties](jedew 4-pack mini hygrometer thermometer digital lcd monitor indoor/outdoor humidity meter gauge temperature for humidifiers dehumidifiers greenhouse reptile plant humidor fahrenheit(℉) or celsius(℃) https://www.amazon.com/dp/B07GR67G1M/ref=cm_sw_r_apan_glt_fabc_PBHHBFMZ0QZVXWG83F56?psc=1) and they've been great! Additionally, it isn't advised you use anything sticky that may come off in the enclosure. I have mine hot glued to the inside facing outwards, works great.

Best of luck!

You need the Inkbird humidity sensor, not the temp sensor, along with a miniature humidifier

Here:

Inkbird Humidity Controller IHC200 Humidistat Mushroom Greenhouse Pre Wired Outlet Dual Stage Humidifier Dehumidifier https://www.amazon.com/dp/B01J1E5LWM/ref=cm_sw_r_cp_api_glt_fabc_JGT9AJHSDHDE906K9F28

You can build drying/curing boxes. Hang dry for a few days if you can first then get large totes or garbage cans. Put a couple PC fans in the sides to pull air in with a few passive exhaust vents. Then use a hydrometer controller to run the fans, probably set it low like 55% and when you get home bovida up to 62. It's not ideal and still might get bud rot especially if they go in too moist, but I think it's your best bet besides just hanging them in a closet until you get back, which might not get you bad results. Link to the type of controller I would use https://www.amazon.com/dp/B01J1E5LWM/ref=cm_sw_r_cp_awdb_imm_dl_YMSP4HYNZJTHBH6XC9ZK

I wish you would have posted a photo or two. By blackened, do you actually mean black in color, or brown and dead-looking? Usually you'll see the sugar leaves turning yellow, and the buds dying and turning a dead brown color, along with a moldy appearance. All affected areas need to be removed.

You should have something like this: https://www.amazon.com/gp/product/B01J1E5LWM/ref=ppx_yo_dt_b_asin_title_o04_s02?ie=UTF8&psc=1

As well as a digital or mechanical humidity/temp gauge. The electronic ones like the link above need to be calibrated (usually) so they're the same reading as your gauge. Then plug in an exhaust fan to the "high humidity" side of the device, and a cool mist humidifier to the "low humidity" side. Humidity in the outside room that the grow tent/closet/etc is in should be kept lower than the desired humidity in the tent. That way the exhaust fan can pull in dryer air.

No plants, not even your lawn, should be watered at night. Being wet and dark is the perfect breeding ground for molds, mildews, and diseases. Water as early as possible in the morning, after the light is on. Excess water (runoff that comes out of the pot) should be removed (a sponge and bucket if nothing else).

It's called a controller. It reads humidity and turns power on and off to an outlet. You can have a humidifier, a fan, a ultrasonic fogger anything plugged in to it. Don't bother with wifi if your on a budget. Inkbird is a great manufacturer and can probably get a basic controller for $40. Then add a humidifier. 👍 https://www.amazon.com/dp/B01J1E5LWM/ref=cm_sw_r_cp_apa_glt_fabc_CRHXC4801C366NF7F68V

All I did was add a controller to the carbon fan. I don't mind a little smell. Fan runs most of the time anyway venting humidity. I use this but I saw them as low as $25. Just search humidity controller. If you get a dehumidifier, you will need a controller anyway. The ones built in a extremely inaccurate. https://www.amazon.com/dp/B07GQWY9HM/ref=cm_sw_r_cp_apa_glt_fabc_2Z5P5B9KNQHGCWDVWM8D

If you don’t believe published CO2 numbers, you can buy CO2 sensors for yourself.

Go ahead. I’ll wait here for you to test out the CO2 levels at your house and see if they’ve risen to 400 ppm or not.

This is what I use in my martha. https://www.amazon.com/Humidity-Controller-Inkbird-Humidistat-Pre-wired/dp/B01J1E5LWM/ref=sr_1_3?dchild=1&keywords=humidity+controller&qid=1617829237&sr=8-3

You don't need to worry about playing in a bone dry room. It's more of a long term effect. The only major concerns as far as immediate effects have more to do with temperature (e.g. taking a guitar out of a case in a warm room after having been in the extreme cold) which could damage the finish moreso than the actual structure.

For some peace of mind, I would recommend one of these to put in your case and make sure the humidity is staying around 50%. I've been using the same humidipaks for YEARS despite the manufacturer telling you to replace them every 2-6 months. They did dry out a bit during the New England winters, but I would kind of "recharge" them by putting them in a humid environment for 24-48 hours to reabsorb some moisture. Worked like a charm and all three of my guitars have stayed at a comfortable 45-51% humidity level.
